Rotary Flap Peening of Aircraft Metallic Structure, Components and Parts
Generally speaking, we want to avoid stresses in metallic structures. But what if having a certain type of stress brought into a component or part actually improves the structure? And so it does. Rotary Flap Peening is related to Shot Peening. Shot Peening is done to pre-stress surfaces of some metallic parts. By doing so, the fatigue strength of the part is increased and it helps to prevent stress- and corrosion cracks. Nevertheless, such surfaces can still get damaged. When damage occurs, the damage must be removed (by blend out and/or smoothening). If still within allowable damage limits, the part must be shot-peened again (after all, the pre-stressed surface at the damaged area is removed). But what if the damaged part is installed on the aircraft and rather difficult or time-consuming to remove? Don’t worry, that’s when they call you. Flap Peening is the Shot Peening of small areas of components or parts that are installed on the aircraft. Flap peening can be done best with the specialized tooling made by Shockform Aeronautique: The FlapSpeed PRO. Aircraft manufacturers (OEM’s) demand that the person who performs the flap peening procedures is qualified and trained.
This training makes sure you become qualified for the job!
Not only will you become familiar with how the Flapspeed PRO works, you also get an extensive explanation of the Flap Peening procedure. After following this training you will fully understand the flap peening procedure given by, for example, Airbus and Boeing.
