The smart tactical missile propulsion system, mated with a target seeker, was launched from a Bradley Fighting Vehicle. The missile successfully impacted near a target which the seeker's automatic target recognizer locked onto during the flight, demonstrating the propulsion system's reliability and predictable performance.

TRW and teammate Talley Defense Systems worked closely with AMCOM to develop the gel system under the Future Missile Technology Integration (FMTI) program. FMTI's objective has been to develop missile technology that can be integrated into future weapons.

"The gel propulsion system performed according to our expectations," said Gary Joseph, manager, TRW Propulsion Systems Center. "It demonstrated the reliability and capability that make our gel systems superior for ground-to-ground and air-to-ground missions. This system is an example of TRW's innovative propulsion technology, providing a discriminating advantage to our customers."

This test follows an initial flight test last year when the missile prototype, integrated with a gel propulsion system but no seeker, successfully flew 8.0 kilometers. During the 51-second flight, the motor fired five times with the missile hitting squarely in the target zone.

Gel propulsion systems are fueled with a viscous, semi-solid propellant combining the best characteristics of solid and liquid propellants. The gel system stores like solid rocket propellant but flows like a liquid when pressurized, enabling throttle and restart capability similar to conventional liquid propellants.

Gels are safer, however, because they do not leak, spill or explode. The gel propulsion system can control the energy to achieve long range while retaining optimal closed-end performance. Gel engines are capable of completely shutting off and restarting multiple times, allowing coast periods conventional solids cannot provide.

The Army recently awarded TRW a study contract to develop gel propulsion technology for Common Missile and modernized Hellfire program applications. The goal of the study contract is to mature the technology for insertion in product engineering, manufacturing and development.

Talley Defense Systems, based in Mesa, Ariz., has been teamed with TRW for almost two decades in developing gelled propellant and pressurization technologies. AMCOM has supported the development with manpower, testing services and facilities.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005
The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India.
