  • a fast approach to model the effects of propeller slipstream on wing load distribution
    53rd AIAA Aerospace Sciences Meeting, 2015
    Co-Authors: Christian Agostinelli, Simone Simeone, Christian B Allen, F Zhu, Abdul Rampurawala
    Abstract:

    In this paper rapid aerodynamic modelling and design tools are developed and validated, in particular to model the effects of propeller slipstream. A numerical method to take into account the effects of wing mounted propeller on aerodynamic performance is validated against RANS Actuator Disk model. Combining a power off (no propeller effects) RANS database, created setting the wing at a number of flight incidences, with a Blade Element Momentum theory module, the method allows variation of parameters such as propeller span and vertical position. A novel method of modelling the physics due to vertical shift of the propeller is also presented. This combines existing slipstream tube contraction models with a geometric transformation of the Tangential Induced Velocity. Following a validation with the inflow angle and the vertical shift of the propeller, an optimisation study of the placement of the actuator disk has been performed. Results have been validated against Actuator Disk simulations, and cost issues considered.
