United States : GENCORP. company successfully completes LEO-46 rocket motor test

August 18, 2014

At the Air Force Research Laboratory (AFRL) at Edwards Air Force Base in California, a GenCorp. company, Aerojet Rocketdyne, has been successful in concluding a hot-fire static test of the first phase solid propellant rocket motor (LEO-46) of its Low Earth Orbiting Nanosatellite Integrated Defense Autonomous System (LEONIDAS).

The GenCorp. company monitored the full-scale, full-duration firing of the 52" diameter by 40ft long motor as it produced around 300,000-lbf of thrust in the 73-second test.

LEO-46 is the first phase of a three-stage propulsion system created for the Super Strypi rail-launched, spin stabilized launch vehicle. The the solid rocket motors (SRM)'s innovative design, together with the launch vehicle architecture's simplicity, allows affordable space access for small satellite packages up to 250kg to 300kg.

With the LEO-46 firing, the series of three successful LEO motor ground test demonstrations gets completed.

The testing of LEO-7 second phase motor and the LEO-1 third stage motor was successful in August 2012 and September 2013, respectively. Aerojet Rocketdyne vice president of the Rocket Shop Defense Advanced Programs, Tyler Evans, said : "This final LEO hot-fire test highlights the success of our robust, affordable large motor development efforts. With the advent of the LEO family of motors, along with our recent large class (92") second stage static tests, Aerojet Rocketdyne is an industry leader in newly developed large solid rocket motors."
