The Walter HWK 109-500 was a liquid fuelled rocket motor developed by Walter in Germany during the Second World War. The 109-500 is a ''Starthilfe'' (take-off assist) motor in a pod, able to produce thrust for thirty seconds. After the fuel was expended, the pod was jettisoned and it returned to earth by parachute,〔Christopher, John. ''The Race for Hitler's X-Planes'' (The Mill, Gloucestershire: History Press, 2013), p.125.〕 with the parachute packed externally, onto the blunt forward end of the pod. It entered service in 1942, and some 6,000 were built, by Heinkel.〔Christopher, p.125.〕 It was "used extensively on a wide range of aircraft", especially the potentially underpowered (when heavily laden with external ordnance) Jumo 004-engined Arado Ar 234B,〔Christopher, p.125.〕 with two of the units uniquely displayed as mounted operationally on the NASM's sole surviving, restored Ar 234B. ==Applications== *Arado Ar 234 *Blohm & Voss Bv 138 *Dornier Do 18 *Heinkel He 111 *Messerschmitt Me 321 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「Walter HWK 109-500」の詳細全文を読む スポンサード リンク
