Abstract

This note describes the design of Transonic Mach Number Sweep system meant to vaxy the Mach number during a b1owdown in the Transonic range (M = 0.8 to 1.40). Mach number steps are achieved by preset controlled operation of Transonic Control13; Flaps. The stepwise increase in Mach number is obtained through divergence of the flaps and vice versa.
