Services
Our Standard Overhaul service is complete blade overhaul to the Original Equipment Manufacturers manual overhaul specifications. We also Overhaul to specific Airline Technical Instructions, OEM Overhaul/Repair Instructions. We are authorized to apply several specialized coatings.
Our Sabor rework process is designed to individually re-contour blade leading edge profiles by the use of specialized tooling and fixtures to ensure uniformity. This makes our SABOR process controlled, measured and repeatable. Our SABOR process restores the original blade profile, restores leading edge radius to original specifications, however, it does not reduce chord width. There can be measurable performance gain and fuel savings by using the SABOR process.
Our SFP (Selected For Performance) measuring process uses a purpose built robotic laser-measuring device that measures blade angle, camber, CP, leading edge radius and chord. These are the most important aerodynamic features of a compressor blade. A proprietary algorithm then computes each individual blade's performance qualities. Each production blade is measured and compared to an optimal blade profile. If a blade optimal profile can be restored then it is reworked using our SABOR process. The blade is then re-measured and categorized as an SFP blade that meets the optimal blade profile for performance. To realize the full performance benefit, SFP blades are designed to be installed in complete sets per engine.
In general these are the SFP measured parameters and how they can affect an engine's efficiency and performance:

In general these are the SFP measured parameters and how they can affect an engine's efficiency and performance:
- 1 degree of angle variation can have a ± effect on pressure ratio
- 1 percent of camber variation can have a ± effect on pressure ratio
- An out of tolerance Coefficient of Pressure can have a ± effect on pressure ratio
- Leading edge radius - a blunt profile beyond threshold radius can reduce blade efficiency
- Chord loss of up to 5% can have a negative effect on pressure ratio - our tolerance is OEM manual limits. Chord alone is not the best predictor of compressor performance.
SFP Benefits
- When you combine SABOR and SFP together there will be a significant gain in engine efficiency
- SFP is a “gate-keeper”, if you will, with tight tolerances for blade angle, camber, CP, Chord and Leading edge thickness to limit outlying blades
- Build your compressor to a verified known build standard using SFP blades - "Predictable Build" will give you predictable results.
- We measure beyond a visual inspection to determine if an airfoil will produce optimal performance.
- This is not a DER, it is an FAA approved process where all tolerances are kept within the OEM limits
- Fleet wide it will produce measurable reductions in fuel burn, reduction of greenhouse gasses and reduce carbon footprint
