4.
Recruiting actions and events
From this point of view, over the last four years have been employed 32 young professionals,
2 of them after getting PhD in USA and France.
After employment, young people were encouraged to pursue doctoral degrees, financially
sustained by institute. 5 are registered at Doctoral Studies. A young woman will support her thesis in
20nd of December 2012 and 2 young people have sustained their PhD in the last year.
After a selection 4 young people, in the final year of study, were employed.
Six specialists have sustained their PhD.
Young employees are encouraged to participate in work on national and international
conferences, competitions for certification and/or promotion for scientific degrees. 38 young people
were promoted by competition.
The policy of attracting young professionals is reflected in several directions:
• Selecting and attracting young people, since they are students, with COMOTI’s specialists
(2 senior research first degree) who have teaching activities, 4 academics from UP
Bucharest and 2 from UT Iasi, or with academics who are collaborating in research programs
(UP Bucharest, UT Iasi, UPG Ploiesti, UT Cluj Napoca, UT Timisoara).
• Selecting and attracting foreign young people, with academics aid from foreign universities,
who are working at COMOTI (e.g. Prof. D.M. Stefanescu from Ohio StateUniversity,
employed during the POS CCE c 174/2010 project).
• Specialization of young employees with teachers from international programs, such as Prof.
Thomas GERBER, COST action “CM0901, specialization courses at Paul Scherrer
Institut, Switzerland for 3 weeks for phd.sudent F. Florean, and Prof. Nicole Stoici from
City University London.
• Attracting young professionals during national and international conferences where
COMOTI’s scientists are participating.
5. Technology transfer activities
From this point of view, technology transfer has concluded transferring the knowhow of
Romanian companies, which have executed some of the products designed and executed by COMOTI
in research contracts, especially the private ones, or those which have had economic partner in national
research plan contracts. For example compressors groups designed by COMOTI have the following
trajectory: A. - COMOTI’s Project; B. - COMOTI’s Execution – execution of specific essential parts
(rotors, bearings, automation, etc.); C. –execution release of parts and subsets with COMOTI’s project
and technology (frames, pressure tanks, valves, special electric motors, separators, etc.) to other
Romanian companies; D. – COMOTI assembly manufacturing (mounting, testing); E. –
Commissioning at the beneficiary; F. – Staff training.
In major manufacturings, w i t h delivery and commissioning at the beneficiary (centrifugal and
screw compressors, air blowers, wastewater treatment plants, etc.), the value of knowhow and
technology transfer is situated between 40-70%. Thus, for example, at value of 5.52 million only for
private sector completed research contracts, technology transfer is EUR 2.71 million at an average of
50% from knowhow and technology transfer value.

Introduction
C112 Computational Fluid Dynamics Department is specialized in axial and centrifugal
blade machines design and CFD analysis. The design is based on the use of specialized programs
like Concepts and in house codes developed and validated in our department. CFD analysis is
performed, also with specialized and validated programs. The two programs used are ANSYS CFX
13 and NUMECA, programs that have certain features for the CFD calculation of bladed machines.
These programs are used by major companies specialized in the field (SIEMENS, DRESSER,
INGERSOLL RAND).
Also the experience in this field has enabled our team to research topics that
have resulted in national research projects conducted by this department. The quality
and the novelty of research topics that were studied were acknowledged nationally
and internationally. One project, with the acronym TRIPLUFLUX, received the gold
medal at International Exhibition of Inventions and New Technologies INVENTIKA
2008.
In addition the experience accumulated in research programs was implemented in the
development of commercial products as blowers for waste water treatment plants or recently
industrial air centrifugal compressor with a pressure ratio of 8.5:1 bar, in three stages, which was
sold last year (2010) in Hungary .

2010-2011 - Participation during MTI for developing a proprietary design of an industrial gas
turbine engine. In the MTI framework ( Motorul cu turbina industrial ) it was assured the safe
operation of the basic components like compressing stages and the turbine stages. The stress and
vibration calculations were realized in order to assess the clearances between the rotating parts
and the gas turbine cases in the critical regions for operation and efficiency.
2008-2011 - The research project FSI ( Platfoma Software pentru analiza interactiunii fluid
structura ). This project was developed in partnership with STRAERO research institute and this
was also the leader. There was studied the complex phenomenon which appear at the interaction
between the aerodynamic profiles used at the blades and the working fluid of the
turbomachinery. A very important phenomenon encountered during the operation of
turbomachinery is the flutter. This process is caused by self feeding oscillations of the
aerodynamic profiles and leads to destruction of the gas turbine. Various methods were studied
such is ONERA method, which is based on finite elements and "meshfree" discretisation using
particles. In this manner is realized the design and safe exploitation of the bladed machinery.
At present are concerned the following research directions:
- The developing of the next generation of the aircraft engines using composite materials, the
development of stress analysis using composite materials.
- The increasing of the safety and cost reduction of the exploitation and maintenance by
implementing real time active monitoring systems of the integrity of parts in the aircraft engines.
- The developing of the software solutions for increasing the efficiency of the research activity
by decreasing the time needed for design cycles.
Regarding the interdisciplinary aspect can be mentioned the participation to FSI project during
which it was studied the interaction between the fluid and the solid and was studied multiple
software algorithms for simulating this. Therefore was involved the disciplines in the stress
analysis domain, fluid mechanics, mathematics and computers programming.
Regarding the initiative can be noted the research proposals in the field of the integrity
monitoring for the aviation composite structures. This monitoring has a beneficial contribution
regarding the increase of the transportation safety and decreasing the maintenance costs in the
field of aerospace structures.
Another initiative deserving to be mentioned is the collaboration with one of the most important
American research institute CONCEPTS . In association with this was implemented software
solutions of the latest generation for increasing the competitiveness in the activity of design and
calculation of the gas turbines.

B. Significant results
The experience and research ability of the research team is highlighted, first of all, by the participation of the members of
the team in research projects. We underline some of the most important results:
1. In the framework of the European project FP7 OPENAIR, between 2009 and 2011, a series of
demonstrators have been manufactured, representing fan vanes made of last generation composites materials,
for the gas turbines of the future. These demonstrators represent a premiere, both at national and international
level, as they combine high quality technologies which aim at civil aircraft weight reduction for decreasing the
fuel consumption and, implicitly, decreasing the aircrafts environmental impact, as well as noise reduction
technologies for decreasing the aircrafts impact on the human communities neighboring airports.
2. In the framework of some national research projects, in 2011 the gas
turbine – afterburner assembly was successfully tested in the gas turbine testing
cell. This achievement crates the premises for continuing advanced research on industrial power
plants equipped with gas turbines for the purpose of rising the thermal efficiency and
environmental impact.
3. Between 2009 and 2010, in the project „Cercetari privind
dezvoltarea de turbine pentru turbomotoare” of the NUCLEU program,
was achieved the design of and axial turbine for an industrial gas turbine
by means of most modern computational techniques. Using these calculus techniques, it can be
obtained improved efficiencies for the gas turbine major components, which leads to a decrease in fuel
consumption and environmental impact. At the same time, the computational techniques reduce the
effort required in the design process and helps shortening the experimental phase, which is intended for validating the
numerical results.
4. The transformation of the aviation gas turbine to work on gaseous
fuel was also achieved by using high level computational techniques, which
allowed the design of the subassemblies necessary for the functional model.
The modified gas turbine was successfully
tested in the experimental facilities and is
the basis of all projects that require
validation through experimentation.
5. The involvement in national interest aviation projects regarding the gas turbines
manufactured under license by Romanian factories, Viper 633-47 and Turmo IVC, as well as
design and certification of aircrafts manufactured in Romania: IAR 93, IAR 99, IAR 330 şi
IAR 316.
C. Dynamic of research subjects
Although, in general, the research conducted by department C122 are oriented towards the gas turbine assembly,
turbines and gas turbine testing, the project in which the department was, and is involved denotes the ability to approach a large
variety of research subjects. We add here some of the projects having distinguished topic:
1. Contract 21-001/2007 - ANCS-PN II, „ Centrală hidropneumatică acţionată de valuri” – CHPV, between 2007- 2010. In this
project it was addressed the possibility of obtaining and electric power plant by using the pneumatic energy of the sea waves.
The C122 department contribution was to conduct the numerical simulations as well as testing an experimental model
manufactured by the project’s coordinator.
2. Contract 20/2007 AMCSIT-RELANSIN, „ Soluţii tehnologice de valorificare a gazului de depozit pentru utilizarea unui
turbogenerator aeroderivativ” – SOLTURB, between 2007- 2010. In this project, it was studied the real possibilities of
exploitation of gaseous fuels resulted in urban landfills for aero – derivative gas turbines fuel supply. Although highly related to
gas turbines, the project also involved manufacturing, storage and transportation of these gaseous fuels, which even led to a
Patent: „Instalatie de alimentare cu combustibil gazos”, Decision OSIM Nr. 1014813/29.04.2011.
3. Contract 93 /2005 - AMCSIT – INOVARE, „ Instalaţie autonomă, complexă de mare capacitate pentru evacuarea apei din
zonele calamitate prin inundaţie” – MTPA, between 2005- 2008. This project came in response to the major floods that
occurred in 2003 in the west part of Romania by proposing an installation equipped with an aero-derivative gas turbine and a
high capacity water pump. Although the project was not finalized with an experimental model, the results obtained during this
project shows the team’s engineering capacity of blending the gas turbines in different terrestrial applications of high social
interest. The project also led to obtaining the Patent „ Instalatie de ventilat”, Decision OSIM Nr. 1032867/30.06.2009.
4. Contract 4N/2006, Program NUCLEU, Project: „ Cercetări privind instalaţii de postardere pentru grupuri de putere integrate
în centrale cogenerative”, between 2006-2 008 and Contract 4N/2006, Program NUCLEU, Project: „ Stand de experimentare
instalaţii de postardere”, between 2007- 2008. In these two projects, the afterburning installation was intensively studied as a
thermal installation attached to a gas turbine for cogeneration power plant applications. The studies conducted reveal the
capacity of addressing complex physic and chemical phenomena such as burning different fuels in the flue gases from a gas
turbine in afterburning installations.

A. Description of the research team
1. Achievements:
INCD GasTurbines COMOTI experience in the field of high speed blade equipments enables to
focus the R & D activities for developing of high tech equipment for environment protection,
respectively centrifugal air blower. Fundamental and applied research results have imposed COMOTI
as unique Romanian producer of centrifugal equipment for wastewater treatment plants, mainly for:
Supply of compressed air for secondary treatment of wastewater treatment plants;
Fat separation and filters cleaning;
Providing necessary oxygen in un-iron processes and / or demagnetization
The centrifugal air blowers have similar performances to the equipments products worldwide, high
reliability, safety in operation and a long functioning period between revisions. The COMOTI
centrifugal air blowers solutions received medals in Geneva and Budapest, and have the market
recognition, such kind of equipments are installed in wastewater treatment plants throughout the
country: Targoviste, Slatina Dej. They have over 85% overall efficiency, and efficiency of the
centrifugal impeller over 92% a high rate of reliability and.
High efficiency is due to constructive system for adjustable flow. The aeration process is entirely
automatic, a special developed software allow the acquisition and reading of measured results,
maintaining a constant values of dissolved oxygen concentration in the water, depending of the real
chemical oxygen consumption, even for wide margins of hourly, diurnal and seasonal water quality
parameters variation.
Research for centrifugal air blowers led to a floating aeration system for water quality
improvement in remote areas (lakes, mountain lakes, marine perimeters, etc.).
Experiments on functional models were done in real operating conditions, and included tests of
components, equipment and command, automation and control system. Water physical and chemical
parameters were monitorised.

Projects:
C125 laboratory staff was and is still involved in research projects with various topics, derived
from the metallic and composite materials, turbo-engines, aircraft structures and aircraft components,
environment domains. During a year of activity (until present 10/20/2011), the C125 laboratory
conducted research activities within the projects:
National projects:
- NUCLEU-PN/2009- 09.07.07- Development of technologies for blade machine7.1 - Research on the
development of composite materials for blade machines. The C125 laboratory team was responsible for
three phases during this project: Phase B17 / Numerical simulations of thermal and mechanical
solicitations in order to choose the composite structure materials; Faza B18 / Developmentand
assessment of preliminary working procedures and instructions, technical training on working technique;
FazaB19/ Manufacturing of composite components and experimental testing. Interpretation of results
obtained and assessment of strengths and weaknesses.
International projects:
OPENAIR”Optimization for low Environmental Noise impact AIRcraft” FP7234313(2009-2013). Within this project period 2009-2011, the composite team
manufactured a serie of demonstrators (prototypes) representing stator blades made from
advanced composite materials, lighter than the classic metallic materials.These prototypes
represents a novelty at national but also international level because it integrates performant
technologies that targets decreasing the weight for civil aicrafts aiming reducing fuel
consumption and environemnetl impact, but also noise reduction technologies for reducing
the impact of aircrafts on communities around airports. The physical manufacturing of the
stator blades has been the result of team complex reserches, which involved performing a complete
technological cycle cstarting from design&geometry, stress analysis, processing and testing the composite
materials up to the manufacturing of the blade using the autoclave technology, within the C125 laboratory
in INCDT COMOTI. Activity of the institute in this project was completed in May 2011, by providing the
prototype – composite stator blade, to the project coordinator, the group Snecma, France. The
encouraging results obtained led to the engagement of the institute COMOTI for another 2 years in this
project (2011-2013).

Introduction
The team which manages the technological researches specific to the metallurgical industry was
organized similarly to all the research and design departments of INCDT Comoti. The team handles
research and design in order to establish casting technologies, forging and heat treatment implied by the
new constructive solutions of the reference products designed by the institute or of those incorporated
in the various research programs, usually requested by the research and design department concerned.
The focus of the technological research specific to metallurgy is finding modern technologies to
provide additional quality to the products to be realized, but as well to achieve economic efficiency.
Also, the research and design activity for the assimilation or putting up the original way of high
technology methods to enable design-research departments to choose modern, reliable and competitive
constructive solutions when producing new products, that are subject of research programs of the
National Institute for Research and Development Turbomotoare.
2.
Technological research projects run between 2007-2011
In the department the activity is oriented towards those technologies that condition the
realization of new products, technologies through which are realized new constructive solutions that
will give to the new product superior technical parameters. Here are closely known the applied
technologies in the field and provide technical assistance to the research and projecting workshops in
order to achieve technological constructive solutions, safe way to obtain a low manufacturing cost. The
team develops the technologies and designs the SDVs to execute the research objects made by the
Institute or in collaboration with specialized units.
The National Institute for Research and Development Turbomotoare Comoti holds the license
from GHH-RAND-Germany company, part of American group Ingersoll Rand, for the production
screw compressors, for natural gas and air, CU64G/D, CU90G and CU128G, activity at which the
department conducted the assimilation of casted semi-finished in Romania foundries and also the use of
other materials than those mentioned by the license in order to improve mechanical characteristics, thus
leading to the possibility of using the same range of compressors for higher pressures and fluid flows.
Another activity of the compartment was materialized in a research contract in which the
National Research and Development Institute Turbomotoare Comoti was a partner in the contract
SENT 233/2006 (07.2006-12.2008): Integrated technology for obtaining unconventional energytechnological sources used as raw materials in developing steel – project responsible engineer
Gheorghe VERDES.
Another program in which the compartment was involved in was the development of the air
centrifugal compressor CCAE 9-125, delivered to LINDE GAS, one of the best known companies in
the world in the industrial air supply. This compressor, of high complexity, required a laborious activity
in terms of designing the technologies to obtain casted and forged semi-finished and achieving the
necessary SDVs.

• 6 dB noise reduction per aircraft operation and equivalent to a cumulative margin of 15-18 EPNdB;
• 7% reduction in CO2 emissions with respect to engines in service prior to 2000.
VITAL will integrate the benefits and the results of on-going research projects with respect to weight
reduction (EEFAE) and noise reduction (SILENCE(R)) technologies, assess at a whole engine level their benefits and
combine their outcomes with those of VITAL:
• 8 dB Noise reduction per aircraft operation (cumulative ~24 EPNdB on the 3 certification points);
• 18 % reduction in CO2 emissions.
WP 2.4 was dedicated to evaluate of performances and economic efficiency of the solution ‘counterrotating
fan’. The perspective is to use this solution to the next generation of aeroengines in service beyond 2020.
4. Activities
For a comprehensive assess of counterrotating solution, WP 2.4 completed four test campaigns, in CIAM C3A anechoic chamber test bench. One of them was for reference data.
The main design logic followed in VITAL was based on concept optimisation mixed with experimental validation.
Following a 1st CRTF design named CRTF1, Snecma and VITAL partners carried out parametric studies to explore
different zones of interest in the conception space (blade count, loading split between rear and front rotors, 3D
shapes). The objectives were again to maximise cruise efficiency and to improve noise emissions over the 3
certification points.
Cycle of conception in VITAL project.
Four test machines were developed:
a) CRTF 1
The basic version of counter-rotating fan was design by SNECMA – Moteurs and included four test
configurations (see below). Was developed with the maximal spacing between rotors. To satisfy this condition, the
first rotor (rotor 1) of the fan is fitted on the inner shaft console using a special extended journal connected with a disk
flange located on the back side of the disc.
Rotor 2 of the fan is fixed to the outer shaft and connected with a booster made of titanium alloy as a blisk. Rotor 2 is
equipped with a Hock of telemetry.

COMOTI design team performed the Fan blisk mechanical pure scale down of cold blade geometry from 800
mm DIA to 22 inches DIA and 3D solid models for all parts of fan module including struts and pylons.
Mechanical team has completed fan module parts mechanical analysis- static, nonlinear analysis for fan, OGV
and IGV blades, dynamic analysis (Campbell diagram) for fan, OGV, IGV blades and cases, tip clearance
computation for fan blade.
Stress and vibration analysis for bladed parts and casings was performed in COMOTI.
COMOTI performed CFD aero evaluation for SRF Fan Module as a standard procedure for bladed machines.
Blade to blade Mach number contour.

The performance evaluation has been done in complete configuration including IGV2, struts and pilons.
c) Counterrotating fan CRTF 2a:
It is an improved CRTF 1 version designed and manufactured by CIAM; prepared for high efficiency. As a
result of this parametric study phase, CRTF2a design (22” diameter) consisted in CRTF1 blade aero-acoustic
optimization using the CIAM 3D-inverse optimization method [5] and matching new constraints relative to blade
thickness. COMOTI was involved in this task ONLY with static equivalent stress analyze in parallel with CIAM.

d) Counterrotating fan CRTF 2b:
It is an improved CRTF 1 version designed and manufactured by DLR; design for high efficiency and
composite blade technology ( ticker blade ). Optimized geometry of blade through more than 3000 iterations.
Four adaptation casings were designed and manufactured by COMOTI in this task.

e) Test bench
All test campaigns took place on C3A test bench – Touraevo Moskow. Aerodynamic and acoustic
measurements has been performed for classical and counter-rotationg fans. Test campaign included the effort of all
partners.
Four basic operating modes were considered:
• Fan Aero Design Point, Cruise (14444rpm, 100%);
• Sideline (14602rpm, 101.1%);
• Cutback (12508rpm, 86.6%);
• Approach (7843rpm, 54.3%).
A COMOTI team was parts in experiments teams, involved in collect experimental data and final analyses of
experimental conclusions.
