Jet Propulsion Test Stand

Product Description

Description of DIDAC Jet Propulsion Test Stand Ram Jet Engine

For operation the Jet Propulsion Test Stand Ram Jet Engine requires incoming air to have a significant approach velocity in order to maintain combustion. The forward speed is simulated by a single stage blower delivering air through a 76mm diameter nozzle mounted 200mm in front of the air intake. The use of gaseous fuel makes a low operating speed and therefore a moderate air supply requirement well within the reach of any engineering laboratory.

The Jet Propulsion Test Stand Ram Jet Engine engine is fabricated from a heat resistant alloy and requires no maintenance even after many years of operation.

Propane a fuel particularly suited for laboratory use is fed to the engine by its own vapour pressure and is controlled by a single valve. Jet Propulsion Test Stand Ram Jet Engine an ignition system ignites the fuel/air mixture at the commencement of operation. Fuel gas flows into the engine through a purpose designed manifold and is measured using a gas flow meter. A unique flame holding baffle serves to create local turbulence and retains the combustion flame within the chamber allowing operation over a wide range of approach velocities.

Experimental Capabilities of Jet Propulsion Test Stand Ram Jet Engine

1. Complete performance analysis at various approach speeds. Calculation of exhaust velocities, measurement of temperatures, thrust, specific thrust, drag and fuel consumption.
2. Collection of gas samples from any point within the ramjet motor.
3. Demonstration and investigation of the ramjet principle.
4. Total and static pressure plots along the ramjet engine axis.
5. Demonstration and investigation of the pulsejet principle.
6. Comparison of Propane with other gaseous fuels, e.g. Butane, Methane.
7. Jet noise investigation using suitable additional instrumentation.

Specification of Jet Propulsion Test Stand Ram Jet Engine
