DISCOVER*The aeroacoustics research experience at PEDECE dates back to the Concorde noise reduction technology.
The expertise covers a broad area of advanced technologies, with focus on aeronautics and space, such as:
generation, propagation and absorption of noise by aircraft, other vehicles and machinery, and its effects on humans (annoyance) and structures (acoustic fatigue) in airport and human environment.
dynamics, performance, stability and control of aircraft, rockets and other vehicles, including classical and novel configurations, and human-machine interface and partial or total automation.
safe separation of aircraft and vehicles for very low collision risk, wake vortex effects on aircraft, flight in adverse weather conditions, airspace and airport capacity.
including mechanical, thermal, electric, magnetic, gravity effects and combinations for fluids, solids and plasmas, in industrial, environmental, geophysical and astrophysical conditions.
The senior staff has 50 years of experience and the junior staff consists mostly of Ph.D.s, with involvement in a variety of private and public national and international projects. A sample of projects supported by the European Union, European Space Agency and Eurocontrol:
(Perspectives for Aerospace Research in Europe): analyses the progress towards the objectives for aeronautical research in the European Union up to 2050, assesses the remaining gaps and recommends measures to be taken to close them.
(Evolution of Air Traffic Management): considers the effect of changes in the overall performance of the Air Traffic Management (ATM), including technical and human factors, to recommend the most cost-effective in terms of final results.
(Community Oriented Solutions to Minimize aircraft noise Annoyance): addresses noise generation by aircraft, sound propagation in the atmosphere and transmission into buildings to minimize the annoyance to residents near airports.
(Future Launchers Preparatory Program): optimizes trajectories of satellite launchers and lifting trans-atmospheric vehicles in terms of the choice among possible launch conditions and the orbit to be reached by the payload to be delivered.
(New Aircraft Concepts Research): compares novel aircraft configurations (like flying wing or engines between U-tail) with a conventional configuration (underwing engines) from the points-of-view of external and internal noise and flight performance, stability, control and handling qualities.
(integration of technologies in support of a passenger and environmentally Friendly helicopter): consideration of how to minimize helicopter noise in all stages of flight, including climb and descent near the ground and cruise at altitude.
(Sound Engineering For Aircraft): aircraft design for low internal and external noise, in the latter case taking into account transmission to the ground and subjective effect on populations near airports.
(Very Efficient Large Aircraft): design of several flying wings capable of carrying 1000 passengers with reduced fuel consumption and emissions in cruise and less noise near airports compared with existing aircraft, providing more air transport asd airport capacity with less environmental effects.
(Research On Silent Aircraft Concepts): new designs and technologies to reduce aircraft noise at the level of the overall configuration and also in the integration of major systems like propulsion.
(Significantly Lower Community Exposure to noise – Reduction): full range of novel technologies to reduce the noise of aero-engines, from the inlet, through the compressor, combustor, turbine and Exhaust, such as non-uniform acoustic liners.
(Jet Exhaust Aerodynamics and Noise): technologies to reduce the noise of jets, like the exhausts of turbojet and turbofan engines, without compromising aerodynamic efficiency and keeping low fuel consumption and emissions.
(Environmental Noise Associated with turbulent Boundary Layer Excitation): minimizing the transmission of external engine and aerodynamic noise through the fuselage into the aircraft cabin to ensure passenger comfort and rest.
(Assessment of Wake vortex Safety): Ensuring safe separation between aircraft in a sequence to land at or take-off from an airport, to ensure a smooth flight while maximizing airport capacity and ability to accommodate schedules at convenient peak times.
(Advanced Propulsion Integration of Aerodynamics and Noise): design of advanced propellers for low and high-speed aircraft combining low noise with high aerodynamic efficiency and low fuel consumption and emissions.
(European Flight Experiments on four-Dimensional Approach and Landing): organizing the air traffic approaching an airport into an orderly queue with aircraft at safe separation landing at precise times to maximize runway and airport capacity.
(Advanced Study of Active Noise Reduction in Aircraft): use of loudspeakers and /or speaking panels to reduce the noise and vibration inside a living space in the presence of external noise sources, for exemple keeping a silent area around passenger headroom in a cabin by cancelling engine noise.
(Applications of Multi-Agent Knowledge-based Systems): automated annalysis of a variety of data from test, certification or routine flights of aircraft, including flight performance, stability, control, propulsion, structure, navigation, communication and other on-board and off-board systems.
(ACOUstic Fatigue of composite and advanced AircrafT structures): fatigue life of composite and advanced structures subject to very high noise and vibration levels, such as aircraft panels near engines or satellite payloads of rocket launchers.
