Aerojet Rocketdyne gets U.S defence contract

Aerojet Rocketdyne announced on August 18, 2014 that the company was recently awarded a contract by Wright-Patterson Air Force Base through the Defense Production Act Title III Office. Under the contract, Aerojet Rocketdyne will make parts ranging from simple, large ducts to complex heat exchangers, and include metals such as nickel, copper and aluminum alloys. The program scope is expected to replace the need for castings, forgings, plating, machining, brazing and welding.

The contract will secure multiple large selective laser melting machines to develop liquid rocket engine applications for national security space launch services. Aerojet Rocketdyne and its subcontractors will design and develop larger scale parts to be converted from conventional manufacturing to 3D printing.

“We have developed and successfully demonstrated additive-manufactured hardware over the last four years but the machines have been limited in size to 10-inch cubes,” said Steve Bouley, vice president of Space Launch Systems at Aerojet Rocketdyne.

“These next generation systems are about six times larger, enabling more options for our rocket engine components. We are extremely honored to have received this contract, and foresee the day when additive-manufactured engines are used to boost and place important payloads into orbit. The end result will be a more efficient, cost-effective engine.”
