INTERORBITAL QUALIFIES ROCKET ENGINE FOR UPCOMING LAUNCH!
by Randa Milliron
MOJAVE-10.21.13---At dawn on October 21, 2013, Interorbital Systems conducted a short-burn flight qualification run of its main rocket engine in a spectacular hot-firing at the Mojave Spaceport. An incandescent 24-foot beam of fire thundered from the engine’s ablative combustion chamber, generating 7,500-lbs of thrust. The test verified several new software systems including automated launch control and launch system health reporting. In addition, the test verified the combustion stability of the engine's secondary hypergolic liquid ignition propellant in an extended igniter burn phase. The video of the test shows a smooth transition from the secondary hypergolic fuel to the primary fuel, turpentine, with a corresponding increase in the brilliance of the plume.Read more on the Interorbital Systems website.
