Axial Flow Turbine Test Bed
Description & Specification
Technical Specifications
The experimental axial flow engine-start turbine comprising a single-stage radial compressor, an annular combustion chamber and a low mass, high-performance axial flow turbine.
The engine has been integrated into a sturdy metal frame that holds it firmly, while enabling accurate measurement of the thrust produced by the engine.
The engine inlet has been replaced with a custom fabricated frontal duct, to enable the air mass flow rate to be accurately measured.
An electronic preprogrammed controller constantly supervises the engine, ensuring safe operating conditions at all times.
The engine is easy to start and stop from the software interface, and automatic, optimal start-up and power-down sequences are already set to assure minimum mechanical stresses. There is no requirement for compressed air supply or propane gas to start the engine.
A tough, transparent polycarbonate screen is fitted in order to make the apparatus completely safe, but still provides excellent visibility of the engine when in use. The screen is removable, enabling full access to the engine and instrumentation.
The engine software runs on a
personal computer, requiring only a single USB interface between the
electronic console and the PC. This enables simple installation into a
test cell or soundproof enclosure.
FEATURES:
- Complete aeronautical axial flow gas turbine engine
