| The Guan single-seat high-altitude fighter was intended
primarily to test the application of turbo-supercharged
engines to fighters, and three prototypes were
ordered at the beginning of 1925.. Of mixed construction,
with metal fuselage, wooden wings and fabric
skinning, and provision for the standard twin synchronised
7.7mm Vickers gun armament, the
Guan bore a close family resemblance to the Gorcock.
The first prototype was completed in June 1926, having
a geared 450hp Napier Lion IV with an exhaust-driven
turbo-supercharger below the propeller shaft. The
second prototype followed early in 1927 with a directdrive
525hp Lion VI and turbo-supercharger mounted
above the propeller shaft. Difficulties with the turbosuperchargers
led to cancellation of the third prototype
and abandonment of the development programme.
