CT58 ER-7 Compressor Blade Coating
Heli-One, in conjunction with
MDS Coating Technologies (MCT), and AeroTech Engineering Consultants, has developed an FAA Approved Repair for the application of MCT’s ER-7 erosion resistant coating on GE’s CT58 engines that extends engine Time-on-Wing (TOW) and improves safety-of-flight in erosive environments. This coating prevents blade erosion from airborne particles in desert operations and has proven to improve: engine efficiency, TOW, safety, and lower scrap rates.
Operational Benefits in Erosive Environments:
- Protects compressor blades
- Minimizes erosion from: sand, ash, and dust
- Extends TOW
- Prevents Leading Edge (LE) curl
- Eliminates LE curl safety-of-flight issues
- Reduces fuel consumption
- Decreases scrap rate through extended blade longevity
