The ground test stand and revolutionary aerospike engine for the Demonstrator 3 rocket, are ready for tests.
The effort was completed in 60 days since the start of fabrication, at ARCA Space Corporation facilities. The system will perform a series of ground tests that will ultimately qualify the engine for flight.
After the ground tests, the same engine will be integrated into the Demonstrator 3 rocket that will perform a suborbital space flight up to an altitude of 120 km above the New Mexico desert. It will be the first ever flight of a linear aerospike engine and the first ever space flight of an aerospike engine.
The engine, with a sea level thrust of 4.2 tons, uses hydrogen peroxide 70% as monopropellant. Despite low energy propellant, the rocket is able to reach space due to the use of an extremely lightweight tank and high efficiency aerospike engine.
