The Midwest MU-1 was an American single-seat, high-wing, strut-braced utility glider that was designed by Art Schultz in the 1930s.[1]


Design and development

The MU-1 was designed by Schultz prior to the Second World War and was used by the United States Army Air Corps for glider training and designated as the TG-18.[1][2]

The MU-1 was constructed with a welded steel tube fuselage and a wooden-framed wings, all covered in doped aircraft fabric covering. The wing was of 36 ft (11.0 m) span, employed a NACA 4412 airfoil and was supported by two parallel struts with jury struts. Landing gear was a fixed monowheel.[1][3]

The aircraft was type certified on 13 October 1944 and about six were completed by Midwest Sailplane and possibly also by the Motorless Flight Institute of Chicago, Illinois.[1][3]

Operational history

In 1983 Soaring Magazine reported that two MU-1s were still in existence, but by June 2011 none was on the Federal Aviation Administration registry.[1][4]


Standard model with 36 ft (11.0 m) wingspan and 172 sq ft (16.0 m2) wing area[1]
MU-1 long-wing
Version with a longer span, double-tapered wing of similar wing area. This model may have been a proposal only as completed examples have not been confirmed.[1]
Schultz ABC
Developed from the MU-1, the ABC has a longer wingspan and higher glide ratio. It won the 1937 Eaton Design Competition[1]
