Aerojet to test AR1 at SSC

Aerojet Rocketdyne and NASA's Stennis Space Center, Miss., signed an agreement for test services and test stand support of the AR1 multi-element pre-burner and main injector. Currently in development, the AR1 engine is a replacement for the Russian-made RD-180 engines that power the Atlas V launch vehicle. This agreement builds on the current assembly and testing of the company's RS-68 and RS-25 engines at NASA Stennis. Aerojet will pay NASA Stennis to modify the E-1 complex, cell 1 test stand over a period of six months. The test stand will be configured to conduct AR1 staged combustion testing. (Source: Aerojet Rocketdyne, 06/16/15)
