UNSTEADY AERODYNAMIC AND AEROELASTIC SIMULATION USING PANEL METHODS
COUPLED TO A FINITE ELEMENT STRUCTURES METHOD AND INCLUDING
AEROELASTIC EFFECTS
Abstract:
The proposed program of work will show that it is possible to
predict the behavior of flight vehicles in response to external
stimuli such as microbursts or wake-vortex encounters, using
tractable high-speed computational methodologies. In the Phase I
work outlined in this proposal, computational tools, based on well
tried configuration modeling methods and
structural analysis techniques, will be applied in the time domain, and their
performance demonstrated modeling typical aircraft in representative
situations. Certain extensions to the numerical flow method would be
investigated with a view to speeding up the calculations when treating the
complex vortex wake/surface interactions. In a subsequent Phase II, the
method would be formalized and implemented, and its performance validated
through comparison between the calculated results and results obtained from
flight and wind-tunnel tests of representative aircraft.
Reduced reliance of wind-tunnel testing of scale models
Reduced prototype development time
Reduced prototype development costs
Reduced technical risk during development
Reduced overall program cost for new aircraft
