【Abstract】 This paper introduces the aerodynamic coupling effects produced by the lead’s vortices in close formation and analyzes the change of lift, drag and side force caused by upwash and sidewash based on Biot Savart law. The calculating formulae of the new formation stability derivatives are derived in the last Example of an application shows that modeling the aerodynamic coupling effects in formation flight is of practical value更多还原
