The Löhr Delta was a propeller-driven delta-wing monoplane, designed and built by Adolf Löhr of Pfarrwerfen, Austria.
Löhr's design was based on the work of Alexander Lippisch and aimed to be an aircraft which had a large wing area, take up minimal space in a hangar, and have good slow-speed flight characteristics.[1][2]
A scale model produced in 1970 verified the qualities of Löhr's design, and led to the construction of a full-size aircraft. It was constructed from composites and aluminium. The centre section of the aircraft comprised a fully faired fuselage, with two occupants sitting side-by-side, a nose-mounted engine driving a tractor propeller, a central fin and rudder, and was supported by a fixed tricycle undercarriage. Control was by full-span elevons and rudder. The outer portions of the delta wing, trapezoidal in shape, could fold up to facilitate storage.[1][2]
The Delta was not inspected during construction, and did not receive official certification of airworthiness.[3] In 1990, taxiing tests were conducted at Zell am See, without any flights being made.[4] The aircraft was later placed on display at the Museum of Vehicles, Technology, and Aviation at Lauffen near Bad Ischl.[1][2]
