Orbital ATK tests rocket motor



Orbital ATK (NYSE: OA), a global provider of aerospace and defense technologies, has announced the successful completion of three consecutive ground-based static firings of a tactical, air-launched high performance propellant rocket motor — the first-ever and one of the largest of its class to be designed, built and static tested at hot and cold extreme conditions, the company said.

With this test, Orbital ATK has successfully demonstrated materials and technologies applicable to future air-launched, high speed weapon systems.

Emerging requirements for high-speed air-launched weapons are driving the need for larger, high performance tactical class boosters. The rocket motor tested contains high performance propellant in a large, lightweight composite case. Orbital ATK´s composite case greatly reduces the inert weight ratio over a conventional metal casing and also incorporates integral launcher attachment and payload interface features designed to withstand captive carry and flight environments.

Under a contract with the US Air Force Research Lab, the tests were all accomplished over a three-week period at the company´s tactical propulsion center of excellence at the Allegany Ballistics Laboratory in Rocket Center, West Virginia, validating motor performance at both the hot and cold temperature extremes required by air-launch tactical missiles and boosters.
