Gloster Guan

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.
