Aerojet Rocketdyne plays role in placing communications satellite

27 January 2014

GenCorp (NYSE: GY) company Aerojet Rocketdyne said it played a vital role in placing the second of three next-generation tracking and data relay satellites (TDRS-L) into orbit for NASA.

The mission was launched from Cape Canaveral Air Force Station aboard a United Launch Alliance Atlas V rocket, with an RL10A-4-2 upper-stage engine, helium pressurization tanks and a dozen Centaur upper-stage thrusters used for roll, pitch, yaw and settling burns.

Aerojet Rocketdyne´s role in the launch primarily began with the second stage, when a single RL10A-4-2 engine ignited to place the TDRS-L into orbit, helped by the 12 Aerojet Rocketdyne monopropellant (hydrazine) thrusters in four modules on the Atlas V Centaur upper stage providing roll, pitch and yaw control as well as propellant settling burns during ascent.
