XCOR Aerospace was an American, privately owned rocket propulsion and spacecraft developer based at Mojave Spaceport in Mojave , California .

history

XCOR was founded in September 1999 by four employees of the rocket manufacturer Rotary Rocket in Mojave: Jeff Greason, Doug Jones, Dan DeLong and Aleta Jackson. The first CEO was Jeff Greason . In July 2012 the headquarters were relocated to Midland , Texas . XCOR considered, among other places u. a. to move to Spaceport Colorado . Ultimately, the choice fell on Midland, as the city government and the Midland Development Corporation lured with financial support of up to 10 million US dollars. Jay Gibson was appointed as the new CEO in March 2015 , Greason and DelOng left the company in November 2015.

In May 2016, XCOR laid off its employees and registered Chapter 7 bankruptcy in 2017.

Completed Projects

XCOR has dealt with rocket-powered aircraft from the start:

  • EZ-Rocket : A Rutan Long-EZ equipped with 1.8 kN rocket drives that replace the conventional propeller drives. The aircraft has also been shown several times at air shows, including a. at the 2005 Oshkosh Airshow . EZ-Rocket was the world's first privately built and flown rocket aircraft.
  • Rocket Racer : The EZ Rocket program led to a second model designed for the Rocket Racing League . It is based on the Airframe of a Velocity SE and was also known as the Mark-I X-Racer. It was powered by a self-developed engine. It is the XR-4K14 engine . This aircraft made various demonstration flights on the EAA AirVenture Oshkosh in 2008 . The thrust of the single engine is said to have been between 6.7 kN and 8 kN. That would be twice as much as with the EZ-Rocket. The engine burns liquid oxygen and kerosene . This combination allows easy storage in the wing tanks. After testing, which was completed in 2008, XCOR was able to complete seven flights in one day by plane.
  • Tea cart engine : A 67N steering engine that uses nitrous oxide and ethane . It is mounted on a mobile frame and has often been started indoors for demonstration purposes and has over 1837 ignitions and 9039 s total running time.
  • Test of LOX / methane rocket engines in 2005.
  • Earlier work on LOX / methane thrusters led to a contract with NASA, together with ATK, a 33 kN strong engine for possible use as a return engine for the Orion CEV moon lander. On January 16, 2007, XCOR announced that it had tested a fully functional previous version.

Lynx

Lynx is a suborbital rocket aircraft that is designed to bring the pilot and payload to an altitude of over 100 km. Between 20 and 50 test flights as well as numerous static engine tests on the ground are planned. A full program of taxi tests, take-off tests and full take-offs is planned to make the aircraft fully operational. Lynx is the size of a small private airplane. Thanks to its reusable, non-toxic engines, it should be able to start several times a day in order to keep operating costs low. Lynx replaces a previous design, the Xerus spaceplane. The development of Lynx was announced on March 26th, 2008 with the aim of developing an airworthy vehicle within two years. This date has been postponed several times, first to spring 2012, then to 2013 and finally to 2015. The Mark II model is expected to fly nine to 18 months after the Mark I prototype, depending on how quickly the test program can be completed.

XCOR Aerospace has already pre-sold 175 Lynx flights for $ 95,000 each.

Nonburnite

XCOR has developed Nonburnite, a cryocompatible, inherently non-combustible composite material based on thermoplastic fluoropolymer resin . A low temperature coefficient and built-in suppression of microcracks make it a suitable material for cryogenic tanks and for the construction of the spacecraft itself.

Joint development of an LH2-operated upper level with ULA

In March 2011, the United Launch Alliance (ULA) announced that they had entered into a contract with XCOR for the joint development of an airworthy upper stage engine. This is to be developed cryogenic with LH2 and LOX. Based on positive attempts to develop a new aluminum alloy engine nozzle using innovative manufacturing processes, ULA believes that the new engine can be built several hundred kilograms lighter and result in lower costs and higher payloads for private and public space travel.

The main objective of the development is the production of an engine with a thrust of 110 to 130 kN, which has significantly lower production costs and is easier to operate and integrate than comparable engines.

The first tests took place on March 22, 2011 and used the LOX kerosene engine 5K18 intended for Lynx. The engine-nozzle combination demonstrated the ability of the aluminum nozzle to withstand the high temperatures in several test runs without any visible wear or changes in the material properties. The tests confirmed the design, choice of materials and manufacturing processes of the nozzle and are the basis for enlarging the existing design.

The duration of the development program will depend on the level of investment required to achieve the goals set within the framework of XCOR's “ build-a-little, test-a-little ” principle. If investments were reduced, the engine would not be ready for five to ten years.
