XV-11A DESCRIPTION AND PRELIMINARY FLIGHT TEST

Abstract

The XV-11A is a polyester reinforced fiber glass STOL aircraft. This four-place aircraft, powered by a 250-horsepower T-63 turbine engine, was designed to achieve high-lift coefficients by means of a variable camber wing with distributed suction boundary layer control. A shrouded propeller was used for thrust augmentation at low forward velocities, and beta control on the propeller was successfully used as a drag increment for glide path control. To date, the XV-11A aircraft has flown 49 flights with a total flight time of 35 hours. The majority of the flight time was involved in aerodynamic research of the shrouded propeller, the distributed suction boundary layer control system and in an evaluation of the general handling characteristics of the aircraft. A minimum of performance data was collected since the primary objective was aerodynamic research. The fiber glass material demonstrated the excellent possibilities of this type of construction when complex, aerodynamically smooth curvatures are desired.
