D.H. 75A HAWK MOTH

摘要

The prototype D.H. 75 Hawk Moth four-seat cabin monoplane made its first flight at Stag Lane aerodrome in December of 1928, but was underpowered with its original de Havilland 'Ghost' V8 engine of 200 hp (149 kW). This engine was replaced with a 240 hp (179 kW) Armstrong Siddeley Lynx seven-cylinder radial and the wingspan and chord was increased slightly, as well as other structural modifications. As a result flight performance was improved and the aircraft was re-designated as the D.H. 75A. This design was intended for the export market; a handful of aircraft were sent to Canada and performed successfully on both wheels and skis. However, the aircraft proved unsuitable as a floatplane and the D.H. 75A could not compete with other new designs available from North American manufacturers.
