2014年2月28日 · NASA’s X-34 program began in 1996 to demonstrate a low-cost, advanced technology flight demonstration test bed for space access and to demonstrate a streamlined management approach with a rapid development schedule and limited testing.

The Orbital Sciences X-34 was intended to be a low-cost testbed for demonstrating "key technologies" that could be integrated into the Reusable Launch Vehicle program. It was intended to be an autonomous pilotless craft powered by a "Fastrac" liquid-propellant rocket engine, capable of reaching Mach 8 and performing 25 test flights per year.

2014年1月30日 · NASA’s X-34 program was initiated in 1996 to provide a low-cost advanced technology flight demonstration test bed vehicle for space access and to demonstrate a streamlined management approach with a rapid development schedule and limited testing.

“轨道科技”X-34是一种专门用于验证“可重复使用航天器”计划“关键技术”的测试平台。 X-34原计划由速度可达8马赫的'Fastrac'液体燃料火箭驱动，每年可进行25次试飞。 2001年该计划由于成本问题被取消，“轨道科技”和罗克韦尔在与NASA签署协议后一年相继退出。 因为两家公司都认为在如此少的预算下完成试验机是不可能的。 X-34后来作为亚轨道可重复使用火箭技术验证机重生。 但是当第一架试验机接近完成时NASA又要求对设计进行大改却不提供任何资金支持，作为承包 …

2016年2月18日 · The X-34 was a single-engine rocket that was to be carried aloft and launched from an Orbital Sciences L-1011 aircraft. On June 29, 1999, the prototype test version of the X-34 made its first captive-carry flight attached to the belly of its newly modified L-1011 carrier aircraft.

NASA failed to attract industry co-investment to develop the original X-34A air-launched, reusable, low-technology, low-cost orbital launch vehicle concept. So the project was scaled back and NASA contracted with Orbital Sciences on 28 August 1996 to build and fly the X-34 unmanned technology demonstrator.

The X-34, being designed and built by the Orbital Sciences Corporation, is an unmanned sub-orbital vehicle designed to be used as a flying test bed to demonstrate key vehicle and operational technologies applicable to future reusable launch vehicles (RLV). The X-34 will be air-launched from an L-1011 carrier

1998年1月1日 · The X-34, being designed and built by the Orbital Sciences Corporation, is an unmanned sub-orbital vehicle designed to be used as a flying test bed to demonstrate key vehicle and operational technologies applicable to future reusable launch vehicles.

2005年1月22日 · The unpiloted X-34 is a technology testbed demonstrator that is designed to demonstrate key vehicle and operational technologies applicable to future low-cost reusable launch vehicles. The vehicle structure is all-composite with a one-piece delta wing design. The vehicle is 58.3 feet long and has a 27.7-foot wingspan.

2000年1月1日 · The X-34 program demonstrates the technologies and operations required to develop the next generation of reusable launch vehicles. The presentation includes descriptions and design views of the vehicle.
