What is the purpose of flap peening?

Flap Peening is mainly used by maintenance and repair professionals for aircraft and helicopters, because it allows a shot peening treatment directly on the area to be treated, without disassembling the part. The Flapper Peening process can also be used for straightening applications on thin aerostructures.

What is Flapper peening?

Rotary flap peening (also called “flapper peening”) was first developed by 3M Corporation in the 1960s for U.S. Army helicopter field repair during the Vietnam war. Rotary flap peening is widely used in the aerospace industry today because it’s ideal for peening small areas on new or repaired parts.

What is shot peen intensity?

Peening intensity is a measure of the average dent capability of the individual particles that make up a shot stream. Dent capability varies from particle to particle. The established procedure of deducing the arc height at the “10% point” accurately indicates average dent capability.

How does shot peening work?

Shot peening works by striking a surface with a shot (round metallic, glass or ceramic particle) with enough force to generate plastic deformation. When a group of shots impact the surface they generate multiple indentations, resulting in the component being encased by a compressive stressed layer on the metal surface.

What can flap peening process be used for?

The Flapper Peening process can also be used for straightening applications on thin aerostructures. Download our brochure to know more about Flap Peening (or Flapper Peening or Rotary Flap Peening) and FlapSpeed Pro®.

Where can I buy a rotary flap peening kit?

When to use flapper peening in a helicopter?

Flap Peening is mainly used by maintenance and repair professionals for aircraft and helicopters, because it allows a shot peening treatment directly on the area to be treated, without disassembling the part. The Flapper Peening process can also be used for straightening applications on thin aerostructures.
