XV-8A Flexible Wing Aerial Utility Vehicle
Abstract
The purpose of this test program was to determine the performance characteristics, the over-all handling qualities, and to establish the operational flight envelope of the XV-8A Flexible Wing Aerial Utility Vehicle. Standard performance, stability and control flight testing techniques were em employed during all phases of operation. Airborne oscillograph recordings and pilot-observed instrument readings were used for data acquisition. A Fairchild Flight Analyzer camera was used to measure take-off and landing distances. The handling characteristics of the aircraft are good. Control harmony between the longitudinal and lateral control systems is excellent, enabling the aircraft to be flown with one hand. Stability in all cases is positive with only light forces required. The flight characteristics of this airplane are similar in most respects to those found in a conventional airplane with a comparable light wing loading. The performance capabilities of the airplane are all within predicted values. The cruise capability is such that a 100-mile mission can be flown at maximum gross weight. Take-off and landing performance proved the STOL capability of the airplane. At maximum gross weight, the take-off distance over a 50-foot obstacle is 1, 000 feet. Landing distance to clear a 50-foot obstacle is 400 feet. During the course of the test program, the airplane proved a reliable and easy aircraft to maintain and service. Some test operations were conducted from unprepared desert surfaces, establishing the capability for operation from areas other than regular airfields. The operational and flying techniques are basically similar to lightweight conventional aircraft. The two-control system lends itself to simplicity and provides adequate control power to permit a fixed wing incidence trim setting for the entire flight including take-off. climb. cruise, descent and landing.
