The X-33 would flight-test a range of technologies that NASA believed it needed for single-stage-to-orbit reusable launch vehicles (SSTO RLVs), such as metallic thermal protection systems, composite cryogenic fuel tanks for liquid hydrogen, the aerospike engine, autonomous (uncrewed) flight control, rapid flight turn-around times through ...

2023年5月3日 · Lockheed Martin's X-33 was a technology demonstrator of the VentureStar orbital spaceplane funded by NASA in the 1990s. Part of the Space Launch Initiative, the X-33's ultimate goal was to prove the feasibility of a completely reusable …

2024年5月11日 · Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV). McDonnell Douglas submitted a vertical landing configuration design which used liquid oxygen/hydr...

2024年6月15日 · X-33/Venturestar（冒险之星）计划是由NASA在1995年发起的，目的是开发一种技术成熟的演示载具，让未来的企业家有信心认为开发商业的单机入轨（Single Stage To Orbit, SSTO）飞行器所需的技术已经足够成熟，且可以在2000年左右开始成功的开发。

NASA-sponsored suborbital unmanned prototype for a single-stage-to-orbit rocketplane. The Lockheed Martin vehicle would have used a linear aerospike engine, metallic insulation, and other features similar to their Starclipper shuttle proposal of 1971.

2009年9月26日 · The most significant project under the umbrella of the Space Launch Initiative (SLI) was the Lockheed Martin X-33 announced in 1996. The ultimate goal of the X-33 was to develop a completely reusable single-stage-to-orbit (SSTO) launch vehicle to replace the aging Space Shuttle by about 2010.

2023年7月26日 · This artist's rendering depicts the NASA/Lockheed Martin X-33 technology demonstrator for a Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV) at high...

The X-33 is a 1/2 scale prototype of a rocket based Single State to Orbit (SSTO) Reusable Launch Vehicle (RLV). The goal of the X-33 program is to reduce the business and technical risks by the end of the decade such that private industry can build and operate the next generation reusable launch vehicle.

The X-33 is an integrated ground and flight operations demonstration of the critical technologies required for a SSTO RLV. The technology development and demonstration activities will be focused on flight demonstrations of the X-33, supported by appropriate ground test. The design of the X-33 and ground test articles will be based

2024年6月13日 · Even if the VentureStar had been build and worked as SSTO, payload would have been limited, even to LEO. Going to GEO and get the comsat market would need a reusable upper stage - called Space...
