SHOT PEENING

Shot peening is a metal working process which enhances the surfaces of a variety of different materials.

Various manufacturing processes used throughout the aerospace, aircraft, automotive, energy, and heavy equipment industries can produce tensile stresses on the surface of components. These processes include milling, turning, drilling, welding, severe grinding, heat treating, bending, and forming. The tensile stress left behind on the surface provides a perfect environment for a cracking or stress corrosion to start forming, reducing the life of these components.

Shot peening is performed by accelerating spherical media toward the surface of a part. When the media hits the part, a small dent is formed, stretching the surface of the part. The material surrounding that dent resists this, and creates an area of compressive stress. When the surface of the part has these small dents all over the surface, there is a continuous layer of compressive stress on the surface of the part. This replaces the tensile stress on the surface with a compressive layer. The compressive layer stops the fatigue cracks and stress corrosion that typically start at the surface of the part.

NON- DESTRUCTIVE TESTING

Prop Care's certificate of approval allows us to undertake Magnetic Particle Inspection (MPI), Fluorescent Dye Penetrant Inspection (FPI) & Eddy Current Inspections (ECI) as an external service. Which means we can MPI all your engine components, your undercarriage legs, any bolts, or FPI wheels, or any alloy parts & release the job with a Release Note.

Prop Care can also carry out the above inspections for Marine, Heavy vehicle, and the Automotive industry including High performance racing cars.

Propeller Re-Pitching

This is a process carried out on “Fixed Pitch” propeller to change the existing pitch to another, to either increase take off performance or cruise performance, but not both, and in fact an increase in one is usually detrimental to the other ie. If your propeller cruises well but you would like to improve the take-off performance the propeller can be re-pitched and it can improve your take-off performance, but your cruise performance will be made a little worse, and vice versa. If you want the best of both worlds you need a constant speed propeller.

As a rule of thumb, every inch of pitch change will reduce or increase the resulting engine rpm at the same power setting by 30 to 50 rpm.
