The Boeing X-40A Space Maneuver Vehicle was a test platform for the X-37 Future-X Reusable Launch Vehicle. ==History== The unpiloted X-40 was built to 85 percent scale to test aerodynamics and navigation of the X-37 Future-X Reusable Launch Vehicle project. After the first drop test in August 1998 the vehicle was transferred to NASA, which modified it. Between April 4 and May 19, 2001 the vehicle successfully conducted seven free flights.〔 In 2001 it successfully demonstrated the glide capabilities of the X-37's fat-bodied, short-winged design and validated the proposed guidance system. 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「Boeing X-40」の詳細全文を読む スポンサード リンク
