Innovative counter rotating fan system for high bypass ratio aircraft engine (COBRA)

Date du début: 1 oct. 2013, Date de fin: 31 mars 2017,

The purpose of COBRA is to use technology breakthroughs to overcome the insufficient noise performance of the counter-rotating fan tested in VITAL FP6 Program. This will be achieved through exploring higher by-pass ratio (15-25) resulting in much lower blade tip speed and blades count. The designs shall comply also with higher or equal aerodynamic efficiency compare to the VITAL ouputs.COBRA is s ...

Tangential Impulse Detonation Engine (TIDE)

Date du début: 1 août 2013, Date de fin: 30 avr. 2016,

The proposed project aims at designing, manufacturing and building of a demonstrator for a new engine concept. The new concept replaces the usual turbine of a classical turboengine by a number of Pulse Detonation Combustors (PDC) placed on a disk that rotates under the tangential impulse provided by the exhaust jet of the PDC. The rotating disk is coupled, through a shaft, to the compressor that i ...

Optimization of air jet pump design for acoustic application (OPA)

Date du début: 1 avr. 2013, Date de fin: 31 juil. 2015,

"According to the call topic, the goal of the project is to optimize the design of a subsonic jet pump, to reduce as much as possible the noise level. The optimization of the subsonic jet pump will be done from the aerodynamic point of view and two type of analyses will be used, a RANS analysis as a “fast-screening” procedure to be able to identify using such techniques a trend in the flow behavio ...

ANotec-COmoti Rotorcraft Acoustics initiative for preliminary acoustic flight tests for the tuning of simplified rotorcraft noise models (ANCORA)

Date du début: 1 juil. 2011, Date de fin: 31 déc. 2013,

"One of the objectives of GRC5 is to implement a tool for the minimisation of noise impact on the ground, capable of being executed on-board “on-the-fly”, providing flight directives to the FMS of the helicopter. To this end reliable and fast noise predictions will have to be made, based on actual flight conditions. The envisaged semi-emperical model to be used for this purpose requires informatio ...

Noise Impact of aircraft with Novel engine configurations in mid- to High Altitude operations (NINHA)

Date du début: 1 oct. 2010, Date de fin: 30 sept. 2013,

"The introduction of aircraft with advanced counter-rotating open rotor (CROR) powerplants will improve specific fuel consumption by 10-15% relative to equivalent turbofans. The NINHA project will assess whether noise issues away from airports (i.e. during high altitude operations) will hazard the introduction of this new generation of powerplants designed to improve fuel burn and reduce CO2 emiss ...

Turboshaft Engine Exhaust Noise Identification (TEENI)

Date du début: 1 avr. 2008, Date de fin: 31 mars 2013,

"Helicopters can generate a large amount of external noise, as their traditional missions –rescue, medical, law enforcement– are very close to populated areas. As emphasised in ACARE SRA2, increasing rotorcraft missions in the public vicinity should not lead to increasing public disturbance. Turboshaft engine is known as a major contributor to exterior noise for take-off conditions. ACARE SRA2 ob ...
