In an old World War II-era hangar here in this blistering-hot town, a passionate group of young aerospace engineers is building a private spaceship called Lynx. 

Developed by XCOR Aerospace, Lynx is the main competitor of Virgin Galactic's SpaceShipTwo, built by Scaled Composites, also in Mojave.

Commercial flights of the Lynx space plane are expected to commence in 2015, mainly through the Dutch company Space Expedition Corporation.

ROCKET SCIENCE XCOR Aerospace Announces Significant Propulsion Milestone on Lynx Suborbital Vehicle

67 second engine test featuring XCOR's 2,500 lb-thrust Lynx main engine (one out of four engines). 

This engine is fed entirely by XCOR's revolutionary rocket propellant piston pumps, which are far more cost effective and manufacturable than turbopumps. 

Both the liquid oxygen oxydizer and kerosene fuel are being pumped into the engine using this techonology. For more information, see our press release at XCOR

XCOR Aerospace has announced a first in aviation and space history, the firing of a full piston pump-powered rocket engine. This breakthrough is the foundation for fully reusable spacecraft that can fly multiple times per day, every day.

It is a game changing technology that has the power to fundamentally alter the way we as a society view, visit, and utilize the abundant resources around our planet and in our solar system.

The initial portion of XCOR's pump test program culminated in a 67-second engine run with the propulsion system mated to the flight weight Lynx fuselage.

After the installation of the flight sized liquid oxygen tank, the next test sequence will extend the engine run duration to the full powered flight duration of the Lynx Mark I suborbital vehicle.

"Through use of our proprietary rocket propellant piston pumps we deliver both kerosene and liquid oxygen to our rocket engines and eliminate the need for heavy, high-pressure fuel and oxidizer tanks. It also enables our propulsion system to fly multiple times per day and last for tens of thousands of flights," said XCOR Chief Executive Officer Jeff Greason.

"This is one more step toward a significant reduction in per-flight cost and turnaround time, while increasing overall flight safety."

Boeing provided additional funding to complete the XCOR test sequence and advance low-cost rocket propulsion technology. The demonstrated results of the full pump fed engine firing for extended periods helps to ensure the technology migrates into broader global applications.

"Unlike the expensive and finicky turbopumps on today's rocket propulsion systems, XCOR's piston pumps are designed to be as powerful in their thrust class as turbines, but as easy to manufacture, maintain and operate as an automotive engine," said XCOR Chief Operating Officer Andrew Nelson.

"This is the culmination of a 12 year program to develop this unique technology. The kerosene piston pump has been successfully flight-proven during our 40-flight test program on the X-Racer aircraft. We'll be entering another flight test program soon with Lynx and these pumps and engines will power XCOR and the industry to the next level."

The Lynx Supersonic Wind Tunnel Model

XCOR Aerospace has announced they have completed the primary supersonic wind tunnel testing of the Lynx suborbital spacecraft. The tests were performed at NASA Marshall Space Flight Center (MSFC) using a precision scale model and demonstrated the integrity of the Lynx aerodynamic shape and provided data to make final refinements to the vehicle.

These new data provide confidence that the Lynx aerodynamic shape will have stable and controllable flight throughout the range of Mach numbers and angles of attack needed for the Lynx mission.

The recent tests add to subsonic wind tunnel testing data obtained by XCOR late last year at the Air Force Research Laboratory in Dayton. As part of a Cooperative Research and Development Agreement (CRADA), XCOR, NASA and the Air Force will all benefit from the data. The tests are a joint effort between XCOR and the AFRL's Air Vehicles Directorate.

Lynx is a two-seat, single-stage winged suborbital vehicle that lifts off from a runway powered by non-toxic, reusable rocket engines. The vehicle can carry safely to the edge of space and back a pilot, one spaceflight participant, and engineering and scientific payloads. The Lynx can be flown up to four times a day with minimal touch labor between flights.
