The General Dynamics Transonic Aircraft Technology (TACT)/F-111A Aardvark is seen In a banking turn over the California Mojave desert. This photograph affords a good view of the supercritical wing airfoil shape.
Starting in 1971 the NASA Flight Research Center and the Air Force undertook a major research and flight testing project, using F-111A (#63-9778), which would span almost 20 years before completion. Intense interest over the results coming from the NASA F-8 supercritical wing (SCW) program spurred NASA and the Air Force to modify the General Dynamics F-111A to explore the application of supercritical wing technology to maneuverable military aircraft. This flight project was called TACT.February 21, 1974NASA Photo / › F-111 TACT Project Description
