The Lockheed Martin X-33 was a proposed uncrewed, sub-scale technology demonstrator suborbital spaceplane that was developed for a period in the 1990s. The X-33 was a technology demonstrator for the VentureStar orbital spaceplane, which was planned to be a next-generation, commercially operated reusable launch vehicle.

2016年2月17日 · NASA selected Lockheed Martin to design, build, and fly the X-33 Advanced Technology Demonstrator test vehicle between March and December 1999. The X-33, a half-scale vehicle, was expected to feature a lifting-body shape, a new "aerospike" rocket engine, and a rugged metallic thermal protection system.

2014年2月28日 · It awarded a contract to Lockheed Martin to build and fly an uncrewed technology demonstrator. Much of the vehicle was entirely new, including the linear aerospace rocket motor and the composite cryogenic propellant tanks. The leap exceeded what existing and developing technology could support.

2021年7月8日 · It was developed jointly between NASA and Lockheed Martin Skunk Works of Palmdale, California. X-33 was cancelled in 2001. The X-33 was designed to take off vertically …

2006年1月4日 · Taking shape at Lockheed Martin’s Skunk Works facility, the X-33 was intended to be a 1/3 scale prototype of a fully-operational RLV (Reusable Launch Vehicle) called the VentureStar, designed to...

2014年2月1日 · Through demonstration flight and ground research, NASA’s X-33 program was to have provide the information needed for industry representatives such as Lockheed Martin to decide whether to proceed with the development of a full-scale, commercial RLV program.

2009年9月26日 · Lockheed Martin X-33 history, specifications, schematics, pictures, and data.

2011年9月27日 · Reusable spaceplanes offered the potential to lower the cost of access to space by an order of magnitude, compared with conventional expendable launch vehicles. Although a cryogenic tank failure during testing ultimately led to the end of the effort, the X-33 team celebrated many successes during the development.

2000年5月1日 · Two "rise-off" umbilicals for the X-33 have been developed, tested, and installed. The X-33 umbilical systems mechanisms incorporate several unique design features to simplify horizontal operations and provide reliable disconnect during launch. Work of the US Gov. Public Use Permitted. There are no available downloads for this record.

1998年1月1日 · This program began by accepting the mandate that included two unprecedented and highly challenging goals: 1) demonstrate single stage to orbit technologies in flight and ground demonstration in less than 42 months and 2) demonstrate a new government and industry management relationship working together with industry in the lead.
