A sub-scale rocket-ramjet combined cycle engine model was designed and will be tested at the Ramjet Engine Test Facility under sea-level static, Mach 4, 6 and 8 flight conditions. The engine operates in the ejector-jet, ramjet, scramjet and rocket modes and this model has two H2-O2 rockets in the duct. Fuel injectors for secondary combustion have been installed in the downstream straight duct section. Each component of the engine was examined experimentally and physical models were constructed. The engine model is 3 m long, 0.2 m high with a width of 0.22 m at the inlet entrance. The pressure level in the rocket chambers is 3 MPa, and net thrust is 4 kN under the sea-level static, design condition.
