XCOR Aerospace is an American private spaceflight and rocket engine development company based at the Mojave Air and Space Port in Mojave, California and Midland International Air and Spaceport in Midland, Texas.[2] XCOR was formed by former members of the Rotary Rocket rocket engine development team in September, 1999.

XCOR is headed by John "Jay" Gibson who is CEO.[3]

History

The company was founded in Mojave, California in 1999[4] by Jeff Greason, Dan DeLong, Aleta Jackson and Doug Jones[1] each of whom had previously worked at the Rotary Rocket company.[5]

In 2001, the XCOR designed and built EZ-Rocket, the first privately built and flown rocket-powered airplane.[6] EX-Rocket made its maiden flight in July 2001, flown by test pilot Dick Rutan.

Rick Searfoss, Chief Test Pilot in 2013, joined the company in the mid-2000s.[7] Scaled Composites record-setting test pilot Brian Binnie joined XCOR in 2014 as both a test pilot and engineer.[8]

XCOR announced a move of its development and manufacturing operations to Midland, Texas in July 2012. XCOR considered a number of locations for the move, including Spaceport Colorado,[4] before announcing that they would be moving their company headquarters and R&D activities to Texas, in part due to a significant set of financial incentives (US$10,000,000[9]) offered to XCOR by the Midland Development Corporation (MDC) and the Midland City Council.[10]

In a 2015 financing round, XCOR attracted capital from Chinese venture firm Haiyin Capital for "vision" reasons, and not as a profitable investment. At the time of the financing round, the company was valued at $140 million.[11]

In mid-2015, John "Jay" Gibson succeeded Jeff Greason—CEO from 1997-2015—as CEO. Greason then became the Chief Technologist.[5][12][3]

In late-2015, three co-founders of XCOR, Jeff Greason, Dan DeLong, Aleta Jackson, left the company to found Agile Aero, an aerospace company focused on rapid development and prototyping of aerodynamic spacecraft.[13]

Lynx rocketplane

For more details on this topic, see Lynx (spacecraft).

The Lynx is capable of carrying a pilot and a passenger or payload on sub-orbital spaceflights over 100 kilometres (62 mi). Between 20 and 50 test flights of Lynx were planned, along with numerous static engine firings on the ground. A full step-by-step set of taxi tests, runway hops and full-up flights were planned to get the vehicle to a state of operational readiness. Lynx was envisaged to be roughly the size of a small private airplane. It would be capable of flying several times a day making use of reusable, non-toxic engines to help keep the space plane's operating costs low.[14] The Lynx superseded a previous design, the Xerus spaceplane.[15] The Lynx was initially announced on March 26, 2008, with plans for an operational vehicle within two years.[14] That date slipped, first to early 2012,[16] and then to 2015.[17] The Mark II would fly twelve to eighteen months afterwards depending on how fast the prototype moved through the test program.[14][17]

As of July 2012, XCOR had presold 175 Lynx flights at US$95,000 each.[1]

Thermoplastic polymer development

XCOR has developed Nonburnite, a cryo-compatible, inherently non-combustible composite material based on a thermoplastic fluoropolymer resin. Low coefficient of thermal expansion and inherent resistance to microcracking make it well suited to cryogenic tank use and also part of vehicle structure.[18] As of February 2012, Nonburnite will be used in the tanks of the Lynx rocketplane.[19]

XCOR/ULA liquid-hydrogen, upper-stage engine development project

In March 2011, United Launch Alliance (ULA) announced they had entered into a joint-development contract with XCOR for a flight-ready, 25,000 to 30,000 pounds-force (110–130 kN) cryogenic LH2/LOX upper-stage rocket engine. Partially as a result of positive results achieved from an earlier (2010) effort to develop a new aluminium alloy engine nozzle using innovative manufacturing techniques, ULA believes the new engine technology will save several hundred pounds of weight from the large engine and will "lead to significantly lower-cost and more-capable commercial and US government space flights."[20]

The "multi-year project’s main objective [was] to produce a flight-ready LOX/LH2 upper-stage engine in the 25,000 to 30,000 pounds-force (110 to 130 kN)-thrust class that costs significantly less to produce and is easier to operate and integrate than competing engine technologies" [21]

2011 demonstration test firings of an aluminum nozzle on XCOR’s Lynx 5K18 LOX/kerosene engine demonstrated "the ability of the aluminum nozzle to withstand the high temperatures of rocket-engine exhaust over numerous tests, with no discernable degradation of the material properties of the alloys. The tests validated the design, materials and manufacturing processes used in the nozzle, and laid a foundation for scaling the design to EELV-sized engines."[22]

Template:Asof 2011, the length of the development program was stated to depend on "the level of investment as milestones are met in the build-a-little, test-a-little approach favored by XCOR." If investment is minimized, flight engines would not be available for five to ten years.[21]

A subscale 2,500 pounds-force (11 kN)-thrust LH2/LOX engine was developed by 2013, named the XR-5H25, in order to support the XCOR/ULA engine development program. The first hot fire test of the prototype engine was in November 2013, the test was deemed successful.[23] It was also the first demonstrated use of a piston-pump-fed LH2 rocket engine, a new method to design "liquid hydrogen rocket engines that fundamentally breaks current cost, reliability and operational models."[23]

In April 2015, ULA announced that the XCOR/ULA joint-development rocket engine is one of the candidate engines for a new ULA upper stage rocket to be fielded no earlier than 2023. The Advanced Cryogenic Evolved Stage (ACES) is a long-life-on-orbit, high-performance, upper stage that, after consideration/competition by ULA, will use one of three engines to go into production with. The other engines under consideration are the 110-kilonewton (25,000 lbf)-Aerojet Rocketdyne RL-10 and the 670-kilonewton (150,000 lbf)-Blue Origin BE-3. ACES will be a second stage for the Vulcan launch vehicle after 2023, in lieu of the Centaur upper stage that is projected to fly on Vulcan as early as 2019.[24]
