A performance analysis has been made to determine whether boundary- layer control by suction might be effective in making the power-off landing distance of a liaison type of airplane less than that obtainable with conventional high-lift devices. The airplane was assumed to be operating from airstrips which would give a combined ground and braking friction coefficient of 0.4. The pay load was fixed at l500 pounds, the wing span was varied from 25 to 100 feet, the aspect ratio was varied from 300 to 1200. Maximum lift coefficients of 5.0 and 2.8 were assumed for the airplanes with and without boundary-layer control, respectively. A conservative estimate of the added weight due to the boundary-layer control equipment was included. The effects of boundary-layer control on the total landing distance, ground run, stalling speed, and sinking speed were investigated.
