The H337H-2 Engine Performance Analyzer is an on-wing performance analyzer specifically designed to test the General Electric CT7 engine. Incorporating performance equations and
algorithms approved by General Electric, the analyzer automatically computes, displays and
prints performance margins and requirements for CT7 engines.
The PACT7:
• Verifies engine performance during
troubleshooting and after module
replacement
• Permits on-wing Interturbine Temperature
(ITT) trim adjustment
• Verifies aircraft ITT, torque and speed
accuracies in the specific engine applications
• Requires minimal time for set-up and testing
• Measures and displays various engine
parameters and calculates functions during
flight line and test cell engine runs including:
- ITT Setting (Trim Resistor)
- ITT and Gas Generator Speed Margins
- Compressor Efficiency
- Cockpit Gage Verification (ITT, Torque, Gas
Generator Speed and Propeller Speed)
