It is a 120-percent-scaled derivative of the earlier Boeing X-40. The X-37 began as a NASA project in 1999, before being transferred to the United States Department of Defense in 2004. Until 2019, the program was managed by Air Force Space Command. [2]

2016年2月24日 · On-orbit propulsion will be provided by the AR-2/3, a highly reliable engine with a legacy stretching back to the 1950s. The X-37 is a reusable orbital launch vehicle put into orbit atop an Atlas V rocket. It was built by Boeing. The vehicle is used by the U.S. military.

X-37B空天战斗机（英文：X-37B Space Plane [1]，又称：X-37B Orbital Test Vehicle [22]，缩写：OTV，又译为：轨道试验飞行器） [2]，是美国 波音公司 研制的无人且可重复使用的 太空飞机。 该机由火箭发射进入太空，是第一架既能在地球 卫星轨道 上飞行、又能进入 大气层 的 航空器，同时结束任务后还能自动返回地面，被认为是未来 太空战斗机 的雏形。 该机最高速度能达到 音速 的25倍以上，常规军用 雷达 技术无法捕捉。 [21] [33] 2014年10月17日，X-37B（OTV-3）已于 …

Reusable satellite satellite built by Boeing for NASA, USAF, USA. Launched 2010 - 2015. AKA: OTV. Status: Operational 2010. First Launch: 2010-04-22. Last Launch: 2015-05-20. Number: 4 . Gross mass: 3,200 kg (7,000 lb). Height: 8.38 m (27.49 ft). Span: 4.57 m (14.99 ft).

除了具备X-40A的功能之外，X-37A还完全装备了太空飞行，配备了用于轨道机动的火箭发动机、先进的可重复使用热防护系统、载荷舱和用于轨道和大气飞行的导航/飞行控制系统。 因此，NASA X-37A的最终意图与美国空军计划的X-40B SMV相同。 在2000年初，空军同意参加X-37计划，随后将X-40A转交给NASA，作为X-37A进近和着陆阶段的试验台。 为此，X-40A被改装为空间集成GPS/INS (SIGI)系统、计算空气数据系统 (CADS)和改装的仪器和遥测设备。 在NASA的一次试 …

The Boeing X-37 is an unpiloted demonstration spaceplane that is intended to test future spaceflight technologies while in orbit and during atmospheric reentry. It is a reusable robotic spacecraft based on the smaller X-40. The X-37 began as a NASA project in 1999, then was transferred to the US Department of Defense in 2004.

In July 2003 an approach and landing test version of the X-37, a spacecraft designed to demonstrate technologies for NASA's Orbital Space Plane Program, successfully completed structural testing at...

这架就是传说中的美国空军神秘太空飞行器X-37B，一种新型太空飞机 Space Plane（港台海外华人多称为太空穿梭机），NASA更喜欢称它为迷你版航天飞机（Mini Space Shuttle）。 其实就是一款太空版无人机，跟航天飞机一样，能够多次往返、重复使用的带翅膀飞行器。 这架太空飞机从2017年9月7日由SpaceX猎鹰9号火箭发射，一直到2019年10月27日最新飞回，总计在轨飞行780天。 由此刷新在轨飞行时间最长纪录。 到底是啥神器？ X-37B太空飞机，被美国空军代 …

2006年4月7日 · It is derived from the X-40A spaceflight and is one of the most modern spacecraft in the world. Fuelled with military fuel JP-8 and hydrogen peroxide, the Rocketdyne engine of the X-37 is designed to run for nine months. The engine installed in the aircraft currently uses hypergolic nitrogen tetroxide or hydrazine.
