__NOTOC__ The Grob G 103 Twin Astir was a two-seat sailplane developed in Germany in the 1970s by Grob Aircraft AG as a counterpart to the single-seat G 102 Astir then in production. Construction throughout was similar, although to preserve the balance of the design, the wings were given a slight forward sweep. While many two-seat derivatives of single-seat sailplanes have fixed undercarriage, due to the added space restrictions created by the second seat, Grob devised a novel retraction system for the Twin Astir. The single wheel was designed to rotate 90° sideways before retracting "flat" under the rear seat, resulting in a rather unusual seating position. This was only incorporated in early examples, later on, the wheel was fixed. Options offered to customers included whether the front seat should be equipped with flight instruments, and whether water ballast capacity should be installed. Production continued until around 1980, when it was replaced in production by the Twin II, a new and not directly related design originally designated G 118 but later redesignated the G 103a. ==Operators== ; *Italian Air Force operated 9 Grob G103 Twin Astir from 1975 until 1999〔(aeroflight )〕 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「Grob G103 Twin Astir」の詳細全文を読む スポンサード リンク
