Compressibility

Compressibility is the measure of the ability of a fluid to be compressed. In aviation, compressibility is a phenomenon that occurs when an aircraft is flying at high speeds, typically at or above the speed of sound. At these speeds, the air flowing over the aircraft can become compressed, leading to a decrease in lift and an increase in drag. This can cause control issues and even structural damage to the aircraft. To mitigate the effects of compressibility, aircraft designers use various techniques such as swept wings, which delay the onset of compressibility, and shock cones, which redirect the compressed air away from the aircraft. Compressibility is an important consideration in the design and operation of high-speed aircraft.
