Abstract:

In the context of manufacturing and servicing shutdown for the gas turbines that presently equip Romanian Naval Forces Fast Patrol Boats (Missile), their replacement is imposed, with high performance, more reliable, newer generation of gas turbines. For this purpose, the consortium has identified for implementation the solution of replacement the propulsion systems that equip the three Fast Patrol Boats (Missile), with ST40M gas turbine propulsion groups, thus leading to performance improvement, especially gas turbines efficiency, and also reducing operating and maintenance costs, for the three Fast Patrol Boats (Missile). Maintenance operations will be conducted in Romania on the entire product lifecycle. This solution does not imply ship structure modifications. ST40M gas turbines insertion and extraction in the cruise and power (high speed) modules will be achieved on the same paths as the old gas turbines, using specially designed tools, devices and checkers. ST40M gas turbine ship installation is achieved through adaptations, in order to use the same fixing points on the ship structure. The supply of fuel, lubricants and air is achieved using the on board, existent installations, only requiring ship-gas turbine adaptations. The ST40M gas turbine command and control system will be entirely new, designed and manufactured by Romanian Research and Development Institute for Gas Turbines COMOTI, from state-of-the-art equipment systems, using high performance process computers. Tests performed on the new propulsion demonstrator group (cruise and power) will be conducted both on project coordinator test bench and ship: yard (harbor) and sea trials. A technical product documentation will be elaborated (technical description manual, illustrated part catalog, maintenance and operation manual, etc.) and naval personnel instruction will be accomplished.

Abstract:

The project involves the development of an innovative concept of hybrid UAV, aircraft type with a vertical takeoff/landing system specific to a quadcopter with applications in combating global warming. Nowadays, global warming is a worrying phenomenon that cannot be stopped. Studies show a temperature increase over the last four decades, upward trend recorded since the 1850s. Among the many causes of global warming are increased pollution, deforestation and overexploitation of grazing. The UAV has integrated ultra-modern sensors for intercepting and locating noise produced by deforestation tools, a video monitoring system and sensors for capturing meteorological data. By optimizing the hybrid flight system together with the aerodynamic configuration of the wing, the UAV will have a high flight range, the versatility of a quadcopter and the flight efficiency of an aircraft, optimal characteristics for fulfilling its mission. The general objective of the project is to align Romanian research, in the field of Energy, Environment and Climate Change, the subdomain of Environment and Climate Change at the level of those from developed European countries. Achieving the project’s goal will lead to increasing the competitiveness of the economic agent AFT R&D by assimilating the RDI results and transferring them to the market. Simultaneously, COMOTI's expertise in the field of UAVs and programmable electronic systems will be improved.

Abstract:

For maintaining a good position on the helicopter market, IAR Brasov SA must develop an industrial production using modern technologies based on TGE European strategy and introduce into the European market competitive products. To improve the acoustic comfort, for crewmembers and passengers for Executive and VIP versions, IAR SA is searching solutions to reduce noise inside the cabin, without making changes on its structure or propulsion system. The main objective of the project is to support IAR Brasov in developing helicopters that will permit from acoustic comfort point of view, to enter the European market with products based on new concepts of advanced materials that respond to the client’s requests. Thus, is aimed to identify new phono-absorbent structures, with high economic potential no just for the helicopter manufacturing industry but also for any other industry (i.e. automotive industry).

The new developed structures will be designed to obtain a reduction of the noise pressure level inside the cabin of approximate 5 dB. The project is structured on 4 clear development steps: existing solutions characterization, search of advanced materials that will comply with requirements, testing and selection of the best-obtained solution and the last step: validation on helicopter.

From the secondary objective one can briefly mention: the acoustic characterization of the helicopters produced by IAR Brasov SA, knowledge transfer from the acoustic domain into the market by undertaking activities specific to industrial research; strengthening practical training of students from the Faculty of Aerospace Engineering, UPB by performing practical training at IAR Brasov and INCDT COMOTI.

Studies and research on reducing aircraft engine noise using chevrons Call name:

Role in this project: Project coordinator

Abstract:

The main objective of the project is to find chevron shapes capable of reducing the noise produced by the jet stream while minimizing the loss of propulsion force.

To achieve these objectives, numerical simulations will be conducted to study the flow field and acoustic field generated by the jet nozzles with and without chevrons,

using commercial software. The number, shape, and immersion angle of the chevrons equipped on the respective jet nozzles will be varied.

After conducting a significant number of numerical simulations, those combinations of the mentioned parameters will be selected for laboratory experiments at the

Faculty of Aerospace Engineering to validate the results. The experiments will be performed using the microturbine engine available in the turbomachinery laboratory,

a microturbine engine acquired from the GUNT company, and the parameters and functional coefficients of the microturbine engine will be measured using the laboratory equipment.

This equipment can be seen in the image to the right.

In the first stage, experiments will be carried out using the basic geometry of the microturbine engine's reaction nozzle, as shown in the image to the left. In subsequent stages,

the basic reaction nozzle will be replaced with other nozzles equipped with various chevron shapes, and acoustic recordings will be made using a sound level meter.

Comparisons will be made between the baseline case without chevrons and with chevrons regarding the level of acoustic power, frequency spectrum analysis, and propulsion force losses.
