Design and development
editThe 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 Midwest 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
editIn 1983 Soaring Magazine reported that two MU-1s were still in existence, but in October 2015 only one was on the Federal Aviation Administration registry.[1][4]
Variants
edit- MU-1
- 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]
- TG-18
- Military designation for impressed MU-1 gliders used for glider pilot training.
