Abstract:
The report describes a lifting surface theory for calculating the aerodynamic characteristics of jet-flapped wings. Based on a finite-element scheme - the method of Elementary Vortex Distribution or the EVD method, the wing and jet sheet are represented by a set of overlapped elementary vortex distributions. A solution is obtained by satisfying a set of mixed-type boundary conditions on both the wing and jet sheet. The EVD method, as described, provides the following spanwise and chordwise loading spanwise variation of induced drag a capability to investigate the effects of part span flaps, part span blowing, rolling, yawing, pitching, and sideslip and total lift and induced drag momentum method, pitching moment, yawing and rolling moments, and side force.
