dc.description.abstract	Measurements of the direct pitching-moment derivatives m and m at transonic speeds for two delta and two swept wing planforms are discussed. The tests were made in the N.P.L. 9½ in. high-speed wind tunnel using slotted liners, a Mach number range from M = 0.695 to M = 1.07 being attained. These measurements extend earlier subsonic results obtained with solid tunnel liners into the transonic range. Comparison with theory is made for one of the delta wings and the effect of a body on the other was examined.	en_US
