Description and Specification for Lab Tenders
Astra Scientific Two Shaft Gas Turbine Engine Test Bench.
The self-contained, fully instrumented, educational two-shaft gas
turbine. Powered by kerosene, the experimental abilities of this
high-quality apparatus enable comprehensive practical investigations
into the principles, and performance of two-shaft gas turbines.
This product helps students to understand the use of this ‘engine’ with a
secondary power turbine, on practical applications such as helicopters
or electrical power generators.
Air passes through a calibrated nozzle and air box, into a compressor,
then into the combustion chamber. A pump transfers fuel from the fuel
tank to spray through a special nozzle into the combustion chamber. A
high-energy spark ignites the air and fuel mixture that flows to a gas
generator turbine. The combustion chamber gives excellent combustion,
low-pressure loss and good flame stability over a wide range of
conditions. A fuel flow control valve on the instrumentation and control
panel regulates the turbine speed. This design reduces the possibility
of over speed.
A steel frame holds a gas generator, power turbine, combustion chamber,
oil and fuel tanks, pumps, ancillaries and guards. Above these is an
instrumentation and control panel with schematic diagram. The clearly
labeled control panel with mimic diagram includes the instrument
displays, controls and warning lights.
FEATURES:
• Specific fuel consumption
• Pressure losses and ratios
• Thermal, isentropic and mechanical efficiencies
• Work and power
SPECIFICATION:
• Small two-shaft gas turbine engine with radial flow compressor and
axial flow turbine as in modern power generation industry. First shaft
is gas generator similar to the Gas Turbine engine, providing hot gas
for a single-stage axial flow turbine. Hot gas is discharged axially to a
larger power turbine of the second shaft and exhausts to the
atmosphere.
• Automatic front motor starter. Ceramic bearings, lubrication through mixing lubricant oil with fuel.
• Hydraulic, water-cooled dynamometer.
• Sensors and indicators for:
temperatures, pressures, speeds, torque, fuel flow rate, airflow rate.
Hour meter for logging operating hour. Human-Machine interface with
touch screen.
• 220V, 1ph, 50Hz or as requested.
