Abstract:

A 16-scale, semispan model of an AFTI-111 concept equipped with eleven remotely controllable hydraulic actuation systems used to control wing shape and horizontal tail angle was tested in the Propulsion Wind Tunnel 16T at free-stream Mach numbers of 0.60 and 0.85 and free-stream dynamic pressures of 400 and 500 psf. Angle of attack was varied from 0 to 8 deg. The objectives of this test were to further develop and refine a computer-controlled self- optimizing wing for continual investigation of optimum wing airfoil contours for specific mission profiles.
