1P Moment Test Rig – Pratt & Whitney, West Virginia, US
Project
The design, supply, and commissioning of 1P Moment Test Rig* to provide accurate and repeatable 1P bending loads and thrust loads to the running engine. Reducing test set-up times, the test rig is dual purpose and used for both production pass-off and 1P testing.
Features
- Maximum 1P moment of 150,000 in-lbf applied to an engine running at 2,000 shp @ 2,200 rpm
- 100 Hz steady-state and transient data measurement
- 3000 channels capacity
- 100 KHz dynamic data measurement
- Dual bleed air control systems that are fully redundant
Capabilities
- Production testing of a turboprop engine
- Simulation of in-flight bending moments on the propeller shaft arising from gyroscopic forces during aerobatic maneuvers
- Simulation of in-flight thrust loads
MDS Project Scope
- Project management
- 1P Moment Production Test Rig, including:
- Cradle
- Bearing assembly
- Tooling
- Front and rear frames
- Load and build ring assemblies
- Counterbalance assembly
- Load strings
- 1P Moment Control System with automission capability to perform automated tests
- Rig-bearing Lubrication System
- 1P Moment Actuator Hydraulic System
* As a result of increased capacity at the Pratt & Whitney facility, and in light of the effectiveness of the first MDS delivered test rig, Pratt & Whitney has commissioned MDS to supply a second rig.
