The Mississippi State University XV-11A Marvel was an experimental American STOL research aircraft of the 1960s. It was a single-engined pusher monoplane fitted with a boundary layer control system. It carried out its initial programme of research on behalf of the US Army in the late 1960s, and was rebuilt in the 1980s as a proof-of-concept for a utility aircraft.


Development and design

The Department of Astrophysics and Aerospace Engineering at the Mississippi State University had been involved in a programme of research into boundary layer control on behalf of the Office of Naval Research and the US Army since the early 1950s, carrying out trials on a modified Schweizer TG-3 glider, a Piper L-21 and a Cessna O-1.[1][2] Based on the results of these studies, the US Army awarded the Department a contract to develop a new STOL research aircraft the XV-11 MARVEL ("Mississippi Aerophysics Research Vehicle, Extended Latitude").[3]

The resultant design was a shoulder-winged monoplane powered by a single Allison T63 turboprop engine driving a pusher ducted propeller. The boundary layer control system used a blower driven by the engine to draw suction through more than one million tiny holes in the wings and fuselage, while instead of conventional flaps the Marvel used a form of wing warping to deflect the wing trailing edges to vary the wing's camber.[1]

The aircraft's wing and ducted propeller were tested on a piston engined tested, the XAZ-1 "Marvellette". The full sized Marvel was built by the Parsons Corporation based at Traverse City, Michigan, being completed in 1966.[1] It successfully completed a 100 hour flying programme for the US Army in 1970, and was then stored.[3][2]

The Marvel was brought out of storage as a proof-of-concept demonstator of a STOL utility aircraft for Saudi Arabia.It was fitted with a more powerful (420 hp (313 kW)) engine and longer span wings, first flying in this form as the Marvel II on 17 August 1982, and carried out a further trials programme.[3]
