Aestus II / RS 72 Rocket Engine
A turbopump version of the Aestus bipropellant rocket engine.
Aestus RS72 Rocket Engine
A turbopump version of the Aestus pressure-fed engine
The RS 72 rocket engine was a collaborative development between the the propulsion teams of Pratt and Whitney Rocketdyne and Airbus DS, Ottobrunn. The RS 72 is a prototype pathfinder engine based on the Aestus thrust chamber and a power pack (turbopump, gas generator, valves, and controls) from the PWR developed XLR-132 engine.
Hot-fire testing of the RS-72 Pathfinder engine has been successfully completed at NASA's White Sands Test Facility in New Mexico.
The test success was a milestone in a jointly sponsored development programme to fabricate and test a 55 kN (12,500-pound) thrust pump-fed prototype engine using the storable propellant combination MMH / N2O4.
The 14th and final test of the engine was on 3 May and operated at 100 percent power for 60 seconds.
The combination of Aestus with XLR-132 turbopump provides increased performance, multiple restarts and a design life of 2,500-seconds.
The RS 72 is designed for higher performance, thrust and reliability than competing pressure fed systems using the same propellants, with application on existing, or new and evolved launch vehicles.
