The Folland Fo. 108 was an engine testbed used by Great Britain during the 1940s.
Description[]
Resembling a scaled up Hawker Hurricane, the Fo. 108 was a low wing monoplane with fixed undercarriage. The large fuselage, which contained a large cabin for two observers and their instruments, was a light alloy semi-monocoque construction, while plywood was used to cover the tail assembly and the wings, which featured split trailing edge flaps and automatic wingtip slots.[2]
History[]
The first design by Folland to reach the hardware stage, the Fo. 108 was developed in response to Specification 43/37, which called for an aircraft capable of testing a variety of aero engines. Selected ahead of designs from Percival and General Aircraft, 12 examples of the Fo. 108 were built,[2] with serials P1774 to P1785.[3]
The first aircraft was delivered in 1940, with examples remaining in service until 27th March 1945.[2]
