A variable-geometry annular cascade-type inlet is proposed and demonstrated. Such an inlet yielded total-pressure recoveries of 0.84 and 0.53 at Mach numbers of 1.9 and 3.05., respectively. Unity mass-flow ratios were obtained at each Mach number with only marginal subcritical stability ranges of mass-flow ratio (?0.03). Angles of attack up to 6 percent produced only moderate decreases in performance.
