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
