Approximate Changes in Aircraft Stability Derivatives Caused by Battle Damage.
Abstract
Approximations of stability derivative changes, due to battle damage, were made for the FDL-23 Remotely Piloted Vehicle. This vehicle is being simulated by the Aerospace Medical Research Laboratory at Wright-Patterson Air Force Base and uses decoupled linearized perturbation equations. The location of the damage was determined by projectile trajectory characteristics, combined with range and target altitude information, and probability theory. Changes in lift and the coefficient of lift were calculated using the geometry associated with an elliptical lift pattern distribution and the location of the damage. Changes in drag and the coefficient of drag were calculated using a flat plate approximation for the damaged surface area. The changes in the slopes of the nondimensional stability derivative curves was determined by analyzing the cause of each and then calculating how battle damage would change the slope of each curve.
