Objective
To generate a basis for quiet and efficient future helicopters. To this end, such tools as code development, feasibility study and experiments are applied.
For validation of the codes featuring now higher prediction performances, wind tunnel tests will be performed with a modern, more complex model rotor again equipped with pressure sensors. A further goal of the wind tunnel tests is to investigate direct noise reduction measures such as low tip speeds and noise oriented flight procedures. For analysing the feasibility of quiet helicopter designs, a dedicated study is conducted.
The activities related to the different tasks are summarized in the following:
Euler and Navier-Stokes Codes:
Prediction methods of unsteady transonic pressure distribution, shocks, wave drag, viscous drag and boundary layer characteristics are improved. The flight condition addressed is mainly hover.
Full Potential Code:
A common prediction model and a validated and documented computer code for transsonic pressure distribution for supplying rotor performances and loads is established.
Boundary Element Methods
Free wake generating codes for prediction of blade pressure distribution particularly for flight conditions with interactions between rotor wake and rotor blades as in descent and flare and for transonic flow conditions are improved.
Quiet Helicopter Study
Chances and risks of future Quiet Helicopter development are studied and the related requirements are defined.
Parametric Wind Tunnel Tests
Wind tunnel tests with a Mach-scaled rotor equipped with pressure transducers and advanced, exchangeable blade tips for code validation and study of noise reduction measures of modern complex rotors will be performed in the DNW.
Aeroacoustic Codes
Aeroacoustic codes addressing high speed and broad band noise are improved and validated, the first by different approaches such as unsteady Euler, acoustic analogy and Kirchoff integral formulation in order to identify the most capable method.
