H337H-2

Product catalog summary

Overview: The H337H-2 Engine Performance Analyzer, also known as PACT7, is a specialized tool designed for on-wing testing of the General Electric CT7 engine. It utilizes approved performance equations and algorithms to compute, display, and print performance margins and requirements.

Key Features:

Verifies engine performance during troubleshooting and after module replacement.
Allows on-wing Interturbine Temperature (ITT) trim adjustment.
Ensures accuracy of aircraft ITT, torque, and speed in specific engine applications.
Requires minimal setup and testing time.
Measures and displays various engine parameters and calculates functions during flight line and test cell engine runs, including ITT Setting, ITT and Gas Generator Speed Margins, Compressor Efficiency, and Cockpit Gauge Verification.

Components:

Data Acquisition Unit: Housed in a rugged, deployable casing with snap locks and a carrying handle, it collects and transmits data.
Display Terminal (DT): A rugged notebook computer with a color touch screen that provides real-time test results.
Accessory Kits: Include cables, hoses, and sensors for engine interface, stored in portable cases that double as protective shipping containers.

Specifications:

Input Signals: Various signal types with specific accuracy levels, such as DC Voltage (±0.1% Full-Scale) and Isolated Thermocouple (±2 °C).
Data Acquisition Unit: Requires 85 to 265 VAC, 50 to 400 Hz or 28 VDC power, with dimensions of 10.2 inches H x 15.6 inches W x 11.0 inches D, and weighs approximately 35 lbs.
