Wave Drag
Wave drag is a type of drag that occurs when an aircraft is flying at high speeds near or above the speed of sound. It is caused by the formation of shock waves and the resulting increase in air resistance. As an aircraft approaches the speed of sound, the air flowing over its wings and fuselage begins to compress and create a series of shock waves. These shock waves generate a significant amount of drag, known as wave drag. Wave drag can be further divided into two types: supersonic wave drag and transonic wave drag. Supersonic wave drag occurs when an aircraft is flying faster than the speed of sound, while transonic wave drag occurs when an aircraft is flying near the speed of sound. Wave drag can have a significant impact on an aircraft's performance and fuel efficiency, and it is a major consideration in the design of high-speed aircraft. Engineers use various techniques, such as aerodynamic shaping and the addition of wingtip devices, to minimize wave drag and improve the overall efficiency of the aircraft.
