Testing of the Strutjet RBCC Engine

The testing of the Strutjet Rocket-Based Combined Cycle (RBCC) engine is described in this presentation. Since 1996 Aerojet has conducted thousands of tests on its Strutjet RBCC Engine. The Strutjet is specifically designed as an RBCC engine. The tests included: (1) Inlet, (2) Rocket Checkouts, (3) Direct Connect Mach 6 and 8, and (4) Freejet M = 0, 2.4, 4.1. The modes tested include: (1) Air Augmented Rocket (AAR), (2) Ramjet (3) Scramjet (4) Scram/Rocket (5) Ascent/Rocket. The Strutjet RBCC engine has been tested across the complete airbreathing trajectory. The presentation shows the results of the tests, through diagrams, charts and pictures.

Strutjet RBCC Engine Performance

In the past two years Strutjet Rocket Based Combined Cycle (RBCC) engine has been tested extensively under the Advanced Reusable Technology (ART) contract from NASA MSFC. RBCC Engines combine the high thrust to weight of the rocket with the high efficiency of the ramjet engine. This propulsion system has the potential to reduce the cost of launching payloads to orbit by up to a factor of 100. In the ART program we have conducted over 100 hot fire tests. The propellants have been hydrogen and oxygen. The Modes tested have included the Air Augmented Rocket (AAR) from M = 0 to 2.4, the Ramjet at M = 2.4 & 6, Scramjet at M = 6 & 8, Scram/Rocket at Mach 8 and Ascent Rocket in Vacuum. This invited paper will present an overview of these test results and plans for future development of this propulsion cycle.
