Aerojet, a GenCorp recently conducted an internally funded test firing of large-scale controllable solid rocket motors. Controllable solid rocket motors are an advanced propulsion capability that combines the simplicity of using solid propellants with the flexibility normally associated with use of liquid propellants.

This test resulted in the largest successful firing of the company's controllable solids product line using a high-power electromechanical valve control system. The electromechanical valve control system is being developed by Aerojet to provide faster responding, smaller and more reliable controllable solids that can be used on larger scale applications, like ORION, and will reduce development risks for controllable solids.

"In addition to proving the electromechanical valve control system, this test successfully concludes a one year effort to demonstrate a lower cost method of fabricating the high temperature device used to control thrust and flow direction in our controllable solid products," said Aerojet vice president of Space Programs, Julie Van Kleeck.

"Aerojet is making steady progress toward improving the performance, cost and reliability of our controllable solids products."

Aerojet's controllable solid product line is critical to stabilizing the flight of space vehicles used in our nation's missile defense and by NASA.

Currently the only company manufacturing and delivering controllable solids products for operational vehicles, Aerojet will continue to develop new capabilities to produce enhanced controllable solids for NASA and other future missile defense applications.

Development Contracts Signed For Future European Launchers

Paris, France (ESA) Jun 28, 2007
This week, ESA signed two key contracts with NGL Prime S.p.A. of Italy, one for the definition of launcher system concepts for the European Next Generation Launcher and the other for the development of a European Intermediate eXperimental Vehicle (IXV). Both contracts are part of ESA's Future Launchers Preparatory Programme (FLPP), which aim is to develop and demonstrate the technologies for a Next Generation Launcher (NGL) for Europe, which is expected to become operational after 2020.
