Ceramic shot peening strengthens the wings to make them stronger

In the aviation industry, the strength and durability of wings are critical. To enable wings to withstand greater loads and risks in flight, scientists have been looking for ways to strengthen them. In recent years, a technique called ceramic shot reinforcement of wings has been invented to make wings stronger and improve their performance. Our ceramic shot is mainly used for wing strengthening to improve the fatigue strength and extend the service life.

Conventional processing of wing wall panels is usually done by CNC integral milling with appropriate mechanical press bending method. Overall milling the complex shape of the wall plate will waste a lot of material, mechanical bending is easy to affect the performance of the wall plate, quality control is very difficult. Today, domestic and foreign aviation manufacturing enterprises are using shot peening technology for wing wall plate processing. The principle is mainly: in the high-speed projectile injection to the surface of the parts, the surface of the plastic deformation, and the formation of a high residual stress reinforcement layer, so that the parts are loaded to offset part of the stress, thereby reducing the stress on the parts, improve the life of the parts. The fatigue life of the blasted parts can be increased by tens of times compared to the original, and the fatigue strength and corrosion resistance are greatly enhanced. Such a thick alloy of raw materials, under the high frequency and high-speed impact of hundreds of thousands of projectiles, into a hard, complex and very thin skin, and finally combined with the skeleton, and finally formed a complete wing, lifting the aircraft to fly in the air at 10,000 meters.
