  • Clean Sky Project » Aircraft Research Association
    In support of a major wind tunnel test by Airbus ARA delivered two customised hub designs whose innovative layout allowed quick accurate and repeatable blade setting changes minimising test time This was achieved in close cooperation with the Office National d Etudes et Recherches Aerospatiales ONERA and the Nationaal Luchten Ruimtevaartlaboratorium NLR who were responsible for the CROR rig itself and the blade design respectively Velociraptor Active flow control aims to influence the natural flow around an aerodynamic body by active or energy consuming methods such as suction or air being blown through the surface One of the aims of this project is seperation control ensuring manoeuvrability and minimising the air vehicle s drag The VELOCIRAPTOR module a synthetic jet actuator delivered by the University of Manchester and ARA provides a single spanwise linear array of 30 synthetic jet actuators In comparison with the previous prototype the VELOCIRAPTOR unit s required part count has been reduced by a third and the lead time for manufaturing reduced by three quarters The power density of the actuator unit has been increased with a demostrated peak velocity of around 90ms 1 at 200V peak to peak The integrated real time actuator health monitoring system represents another important step towards the applicability of such actuators in aviation CARD The increasing concern about the adverse environmental effects of engine emissions has resulted in the need to identify methods to reduce the fuel burn of helicopters A major source of aerodynamic drag for helicopters is from the rotor hub hence the interest in this area Thus significant fuel burn reductions are envisioned via drag reductions obtained by a new generation of suitable fairings arount the part of the hub exposed to the airstream The experimental CARD research program undertaken by ARA the University of Glasgow and VZLU the Aerospace Centre of the Czech Republic aims at accurate qualitative measurements of the effectiveness of different fairings by designing maufacturing and testing a customised helicopter model with a powered rotor Its significant size a quarter scale Dauphin about 3m long will enable accurate three dimensional flow visualisation to identify the vortex systems responsible for the rotor hub drag LOSPA Despite the recent major advances in the reduction of aircraft engine noise there is still a great concern of the effects of this noise on the local environment during take off and landing One potential method of further reducing these effects is using innovative horizontal tailplane designs as a noise shield for engines mounted on the rear fuselage ARA will lead a program of work supported by Future Advanced Manufacturing Ltd FAM to design and manufacture an innovative wind tunnel model to enable the acquisition of aerodynamic and acoustic data Nacelles and pylons will be included to accomodate two turbofan simulators which are to be supplied by DNW or ONERA A set of high aspect ratio wings will be produced incorporating removable leading edges and trailing edge flaps This will allow a wide range of configurations to be investigated
