15. The F-22 Design Minimizes Radar Detection
The F-22 Raptors angular shape was purposeful. The aircraft has plenty of curved shapes with shifting radii. The reason they are curved is it allows the aircraft to break up radar beams when it is hit rather than enemy’s radar retrieving the beams. On the exterior, there are zero right angles. The design includes sawtooth edges aligned across the outside of the cockpit. These edges appear on the opening and doorways as well. The edges perform a similar function to the curves by scattering radar beams. The wings, on the other hand, are designed, so the aircraft appears smaller on enemy’s radar. The F-22 designers accomplished this by aligning the edges of the main wing and rear wing.
