Cornelius XBG-3 : ウィキペディア英語版 | Cornelius XBG-3
The Cornelius XBG-3 was an American "bomb glider", developed by the Cornelius Aircraft Corporation for the United States Army Air Forces. Using an unconventional design that included a forward-swept wing, a single prototype was ordered in 1942; however the contract was cancelled later that year before the aircraft had been constructed. ==History== Early in the Second World War, the United States Army Air Forces initiated research into the possibility that gliders, towed by other, conventional aircraft to the area of a target, then released and guided to impact via radio control, could be a useful weapon of war.〔Gunston 1988, p.28.〕 Essentially an early form of (very large) guided missile,〔 the concept was similar to a Navy project underway at the same time, known as Glomb (from "glider-bomb"),〔Parsch 2009〕 and led to the establishment of the 'BG' series of designations, for 'Bomb Glider', in early 1942.〔〔 Among the designs considered for use as a bomb glider was an unconventional design submitted by the Cornelius Aircraft Company. Cornelius, having established a reputation for unconventional aircraft designs,〔Miller 2001, p.297.〕 proposed a design that featured a "tail-first" configuration,〔 with canard foreplanes and a radical forward-swept wing.〔 The USAAF considered the design interesting enough to award a contract to Cornelius for the construction of a single prototype, designated XBG-3.〔Mondey 1978, p.132.〕 However the project was cancelled in late 1942, when the bomb glider concept was abandoned by the USAAF.〔〔Jane's 1947〕 An enlarged, tailess, forward-swept wing glider would be built by Cornelius later in the war, acting as a "flying fuel tank" for long-range bombers, as the XFG-1.〔("Gliding Gas Tank May May Refuel Planes On Ocean Hops." ) ''Popular Science,'' August 1944, p. 124.
