The Schweizer SGM 2-37 is a two-seat, side-by-side, fixed-gear, low-wing motor glider. It was designed at the request of the US Air Force for use at the Air Force Academy.

Recognition (WEFT)

W — Wings	Low-mounted, straight
E — Engines	1 × piston, nose-mounted
F — Fuselage	8.5 m fuselage
T — Tail	Conventional

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Two-seat motor glider with side-by-side seating and fixed landing gear
Long low wing of about 18 m span, with leading-edge cuffs
Nose, cowling and engine installation adapted from the Piper PA-38 Tomahawk

Look for a motor glider with a very long low wing, a single propeller on a Tomahawk-style nose and two side-by-side seats.

Specifications

The Schweizer SGM 2-37 has a length of 8.5 m (28 ft).
It has a wingspan of 18.14 m (60 ft).
Its maximum speed is 219 km/h (136 mph).
Typical crew: 2.

History

To save time and money it used existing parts: the nose, cowling and engine installation of the Piper PA-38 Tomahawk, the wings of the Schweizer SGS 1-36 Sprite with extensions and leading-edge cuffs, and the tail of the SGS 2-32. It was powered by a 112 hp Lycoming O-235.

Variants

The Air Force designated it the TG-7A, and the basic airframe was later developed into the SA 2-37A and B covert surveillance aircraft.

Where you'll see it

Twelve were built between 1982 and 1988, nine of them for the Air Force Academy, which retired its TG-7As in April 2003. The US Coast Guard also used the type.
