Measurable engine performance, industry recognised EGT margins for CFM56 engines.
It’s precisely why operators choose Aero Norway.
Up to 15˚C higher than industry standard. Reduced costs and improved reliability.
The greater the EGT margin achieved, the healthier the engine. So from a commercial perspective Aero Norway’s customers’ engines will last longer on wing, and the engine components, especially in the hot section, will remain in better condition.
EGT refers to Exhaust Gas Temperature, it is a measure of the performance efficiency of the engine to produce the designed level of thrust. During certification, every engine is assigned an absolute operating limit – EGT red line. The difference between EGT red line and the gauge reading in the cockpit is EGT Margin. It is industry-recognised that Aero Norway provides customers with best-in-class EGT margins across the CFM56 family of engines.
There are ten basic rules that we abide by to sustain performance results:
- Tooling quality and routine checks. (Scheduled measuring of critical fixtures.)
- Shop practice and machining of honeycomb seal, HPT and HPC blades. (Custom grinding.)
- Training and information continuous pursuit of best practice.
- Introduction of recommended Service Bulletins. (HPC, HPT Nozzle/HPT Blades/Comb.ch. and HPT Shroud are key areas for performance optimisation.)
- Selection of the right parts. (Inherent component quality is returned after an Aero Norway managed repair.)
- Cleanliness in the shop.
- Engine testing after shop visit. (Following OEM recommendations.)
- Aero Norway Engine Maintenance Programme. (Application of ‘Aero Norway standard’ limits whilst recognising the shop-manual limits.)
- Borescope inspection after test. (Record HPC blade tip rub and HPT/Shroud rub.)
