Alliant Techsystems has certified its Advanced Propulsion Research Complex (APRC) during a recent direct-connect test of a Variable Flow Ducted Rocket (VFDR) propulsion system.

APRC is the only domestic facility capable of developing accurate pre-flight assessments of next-generation tactical missile propulsion systems for high speed, long range, time critical strike mission needs.

The technologies demonstrated in the APRC are critical to the development of next-generation air-to-air, air-to-surface, and surface-launched tactical missile applications. It is a clean-air facility capable of evaluating solid- fuel integral rocket ramjet and scramjet propulsion systems without incurring the costs associated with airborne flight tests.

When combined with ATK's X-43A program, which set the world speed record for air-breathing powered flight at Mach 10, the APRC propulsion demonstration places ATK on the leading edge of hypersonic ramjet and scramjet technology innovation.

VFDR engines use the same solid propellants found in current missile propulsion systems. However, VFDR technology can more than triple the energy output.

ATK's technology demonstration will significantly enhance the effectiveness of next-generation missiles by giving them up to three times the range of current rocket systems while flying at Mach speeds that today's technology can not meet.

The APRC can test propulsion systems over a range of Mach numbers up to Mach 6, and simulated altitudes of up to 42,000 feet. Additional upgrades to the facility are under way to enhance both Mach number and altitude test capabilities with Mach 10 and 100K feet set as goals, respectively. Located in Rocket Center, W.Va., ATK operates this facility for the Naval Sea Systems Command - NAVSEA.

Russia Suggests Spaceship Standardization

Moscow (UPI) Feb 03, 2005
Russian space officials have suggested standardizing the systems of new spaceships so crews could come to each other's aid, local media reported Thursday.
