The Handley Page H.P.39 was a wooden biplane design of the late 1920s. The aircraft was intended to compete in a competition proposed by the Daniel Guggenheim Fund for the Promotion of Aeronautics - the Guggenheim Safe Aircraft Competition. The original working name for the aircraft was the Guggenheim Competition Biplane. The name Gugnunc was at first unofficial, coming from the ''Pip, Squeak and Wilfred'' newspaper cartoon (in the ''Daily Mirror'' and later in silent films), but it later became official. ==Construction and operation== Only one example of the type was constructed, allotted civil registration G-AACN. It used slots and flaps to achieve the necessary low speed and short takeoff and landing distances for the various safety prizes. The aircraft competed in the competition in 1929. Most of the competitors failed to enter due to mechanical problems or failure to satisfy the organizers' safety checks. The Gugnunc performed adequately but did not win any prizes. While there, the HP team noticed that the Curtiss competitors were using an unlicensed version of the Handley Page slot. In the following legal battles, the Curtiss lawyers brought up a postwar judgement that foreign aircraft (and particularly HP aircraft) were prohibited from being imported into the US. On return to the UK, the aircraft continued experimental flying, and was ultimately purchased by the Air Ministry, given registration K1908, and allocated to the Royal Aircraft Establishment for further testing. The aircraft was struck off in 1934 and presented to the Science Museum. It is currently displayed in the Science Museum annex at Wroughton, Wiltshire. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Handley Page Gugnunc」の詳細全文を読む スポンサード リンク
