XCOR Completes DARPA Contract
Mojave CA (SPX) Oct 21, 2004 XCOR Aerospace announced Wednesday it has completed another significant milestone in its Pump-Fed Rocket Program by successfully pumping liquid oxygen through a cryogenic liquid oxygen pump developed by XCOR. The cryogenic liquid oxygen pump is driven by a motor unit that has been operating to requirements for over a year. Previously, the pump had been pumping liquid nitrogen. Both motor and pump are piston machines, rather than the more traditional turbo-centrifugal hardware. The pump's size is matched to XCOR's 1,830 lbf thrust LOX-kerosene engine under development with private investment funds. The pump's success completes a Defense Advanced Research Projects Agency (DARPA) Phase II contract. DARPA's objective for this contract was to develop a low cost, highly operational alternative to turbo pumps for high performance propulsion systems. DARPA is the central research and development organization for the Department of Defense (DoD). It manages and directs selected basic and applied research and development projects for DoD, and pursues research and technology where risk and payoff are both very high and where success may provide dramatic advances for traditional military roles and missions. "This contract has helped us develop the rocket engines for our Xerus vehicle as well as for several potential DoD programs," said Rich Pournelle, Director of Investor Relations. The Phase II contract follows the successful completion of Phase I and Bridge Phase contracts that developed the pump design through concept proof and preliminary design of a flight configuration. XCOR qualified for accelerated award of the Phase II contract by matching the government award with private capital. The second phase allowed for the construction and test of prototype flight pumps for liquid oxygen and kerosene propellants. Dan DeLong, XCOR's Chief Engineer said, "We are very pleased with our progress. This liquid oxygen pump will greatly improve our ability to reach suborbit in the Xerus." The company will now focus on securing a combination of government contracts and additional private investment to continue development of a suborbital vehicle for space tourism, microgravity research and microsatellite launches.

Successful First Test For Vega's Zefiro 9 Engine
Paris, France(ESA) Dec 28, 2005Flames, smoke and a deafening noise accompanied the first firing test of Vega's Zefiro 9 third-stage solid rocket motor. A first examination of the data indicates that everything went well at the test carried out yesterday at Salto de Quirra in southeast Sardinia. |
