XCOR Aerospace is an American private spaceflight and rocket engine development company based at the Mojave Air and Space Port in Mojave, California, Midland International Air and Spaceport in Midland, Texas[2] and the Amsterdam area, the Netherlands.[3] 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.[4]

XCOR Aerospace is the parent operation and is concerned with engineering and building spaceships. There are two main subdivisions within it; XCOR Space Expeditions provides marketing and sales, and XCOR Science conducts scientific and educational payload flights.

History

The company was founded in Mojave, California in 1999[5] by Jeff Greason, Dan DeLong, Aleta Jackson and Doug Jones[1] who had previously worked at the Rotary Rocket company.[6]

In 2001, XCOR designed and built EZ-Rocket, the first privately built and flown rocket-powered airplane.[7] EX-Rocket made its maiden flight in July 2001.

XCOR moved its development and manufacturing operations to Midland, Texas from July 2012 to 2015.[5] The company uses the Mojave Air and Space port primarily to conduct test flights.[8]

In 2015, XCOR attracted investment from Chinese venture firm Haiyin Capital, valuing the company at $140 million.[9]

In mid-2015, John "Jay" Gibson succeeded Jeff Greason—CEO from 1997-2015—as CEO.[4][6][10] Later that year three of the co-founders, Jeff Greason, Dan DeLong and Aleta Jackson, left the company to found Agile Aero, an aerospace company focused on rapid development and prototyping of aerodynamic spacecraft.[11]

In May 2016, the company halted development of the Lynx spaceplane and pivoted company focus toward development its LOX/LH2 engine technology, particularly on a funded project for United Launch Alliance. The company laid off more than 20 people of the 50–60 persons onboard prior to May.[12]

Lynx rocketplane

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

The Lynx was planned to be 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.[13] The Lynx superseded a previous design, the Xerus spaceplane.[14] The Lynx was initially announced in March 2008, with plans for an operational vehicle within two years.[13] That date slipped, first to 2012,[15] then to 2015[16] and in January 2016 the company declined to give a projected date for the first test flight.[17] The Mark II was projected fly twelve to eighteen months after the first test flight depending on how fast the prototype moved through the test program.[13][16]

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

As of 31 May 2016, XCOR has laid off a significant portion of its workforce and has placed the development of the Lynx Spacecraft on indefinite hold to focus on development of a rocket engine.[18]

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.[19] As of February 2012, Nonburnite will be used in the tanks of the Lynx rocketplane.[20]

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."[21]

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" [22]

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."[23]

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.[22]

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.[24] 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."[24]

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.[25]

XCOR Space Expeditions

History

The Space Expedition Corporation (SXC) was founded by Harry van Hulten and Lt-Gen (ret.) Ben Droste in 2008. Initially operating under a wet-lease agreement with XCOR Aerospace, it was acquired by XCOR Aerospace in June 2014 and is now a fully owned subsidiary. Michiel Mol and Maarten Elshove joined SXC in 2010 and are thus considered founders. After the acquisition by XCOR Aerospace SXC has been rebranded as XCOR Space Expeditions and is fully integrated into the XCOR brand. XCOR Aerospace is since organized as part of XCOR Corporate, but operates as the center of XCOR.[35]

XCOR Space Expeditions is based in the Amsterdam area, the Netherlands, and has a regional sales office for Asia in Hong Kong.[36]

XCOR Space Expeditions works closely with a global network of 35 independent resellers, also called space agents, that sell tickets for a flight on the Lynx Mark I or Lynx Mark II to the public.[37]

Space Flights

XCOR Space Expeditions offers suborbital flights with the XCOR Lynx Mark I and Lynx Mark II Spaceships for the public. It will operate from Mojave, California, and Curaçao, where a spaceport is planned to be built.[38] There is no official date set for the start of operation.

XCOR Space Expeditions also offers medical check ups, training missions with space simulators and G-Force Fighter Jet flights for ticketholders, among other preoperational missions and events.[39]

Strategic partnerships have been created with global companies such as Philips, KLM, Heineken, Unilever and Luminox, among others.[40]

XCOR Science

XCOR Science will offer payload flights for educational institutions and science to conduct experiments in space.[41]

The Lynx Mark I and Mark II allow a maximum payload of 140 kg to be transported into space besides the pilot. Payloads are separated into two parts, whereas Payload A with a maximum capacity of 20 kg is situated in a vessel behind the pilot seat. Payload B with a mass up to 120 kg takes the space of the second seat.[42]

It is planned in the future to develop the Lynx Mark III which will have the same capabilities as the Lynx Mark II and will fly up to 100 km above ground. In addition to the payloads of the Lynx Mark I and II, the Lynx Mark III will have an external dorsal mounted pod which will hold up an extra 650 kg.[42]

Payloads will only be available from the Mojave space station in California.[42]
