P7674 Ejector Bench

The principle of operation of an ejector is simple: a high velocity steam jet blows into the ejector throat and thereby produces a suction which draws a fluid into the throat at high velocity.

FEATURES

• Compact modular design
• Easy installation
• Comprehensive instrumentation
• Pressure test certificates supplied for major components
• Low capital cost 

Steam Head Assembly

Mild steel steam header welded in accordance with BS2633 (1973) with a branch providing a steam supply to the ejector. The steam header is enclosed within a header box and fully insulated with mineral wool.

Certification

The steam header is pressure tested at 21 bar and is supplied complete with a test certificate.

Inter-Connection of Steam Benches

To enable steam benches to be linked to form a system utilising a common steam supply and service system, the steam bench is supplied complete with:

• An interconnecting back panel and student work surface.
• A set of 4 stainless steel flexible hoses for the steam and service connections.
• A section of aluminium clad lagging for the flexible steam hose.

P9010e Turbojet Engine Test Stand

Cussons Turbojet Engine Test Stand provides a fully functioning, aero derivative small jet turbine.

Turbojets are used as high performance jet engines in aircraft and to provide the core of the very successful turbofan engines used on the great majority of airliners.

Cussons Turbojet Engine Test Stand provides a fully functioning, aero derivative small jet turbine. The jet turbine thrust can be measured and outputs from up to 230N can be achieved. The unit is provided with a mimic diagram displaying the temperatures of the gas flow and engine pressure ratio. Air flow, fuel flow and rotational speed measurement mean that an energy balance for the engine can be undertaken.

EXPERIMENTS / LEARNING CAPABILITIES

• Demonstration of the Turbo jet principle
• Performance analysis of a Turbojet at varying power
• Temperatures air inlet
• Fuel inlet compressor outlet
• Combustion chamber outlet 
• Tail pipe stream
• Ambient air pressure
• Air inlet differential pressure
• Compressor outlet pressure
