Customer Challenge
Standardization of loom assembly across aero engines
A global aero engine manufacturer needed a new loom assembly design for every engine program – the activity was always on the critical path of Engine Development Program
Scope
Standardize Flight Test Instrumentation (FTI) lead-out loom assembly through:
- Sensing pick-up point to disconnect panel
- Disconnect panel to Data Acquisition Unit (DAU)
Solution
- Study FTI measurement matrix applicable for each temperature zone
- Review & propose lead-out, end-connector, cable details for various measurements
- Propose arrangement layout for lead-out routing from different measurement zones
- Calculate loom length from measurement pick-up point to disconnect panel and disconnect panel to DAU
- Study surrounding geometry and devise lead-out strategy
- Develop concept devising various lead-out techniques, standards, and securing methods
- Standardize the loom length applicable for each of the measurement zones
- Create standard loom assemblies of all variants
- Define lead-out matrix for each measurement zone
Features
