![]() For air flowing through this shock wave, there is a sudden change in density, pressure, and temperature. The shock wave is a result of fluid, in this case, air, being unable to react to the sudden disturbance from the aircraft. However, when the object moves at such a high speed, shock waves are formed, which can alter the aerodynamics of the aircraft. To deal with the aerodynamic characteristics at such speed, supersonic airfoils are required on the aircraft. Supersonic flights travel faster than the speed of sound, i.e., Mach 1. In this article, we will discuss these design requirements in detail. An understanding of the aerodynamic characteristics of a supersonic airfoil and the acting forces is, therefore, an important part of supersonic aircraft design. At supersonic speed, airfoils need to be designed in such a way that enough lift is generated and in an efficient manner without compromising the performance of other aircraft components. However, the mechanism of generating lift on such aircraft requires some strict design changes compared to regular aircraft.Īt different speeds, the air conditions for flight vary. Airliners like Concorde are supersonic, i.e., they are able to fly faster than the speed of sound. Engineers and designers are constantly working on designing aircraft that are faster and more efficient. Since the invention of aircraft, there has been a massive improvement in aircraft technologies. Supersonic airfoils are usually swept with a thin cross-section to reduce drag.ĬFD simulation of supersonic airfoils facilitates the maximization of supersonic flight efficiency Supersonic flights travel at a speed faster than that of sound, i.e., Mach 1.Īt high speed, airfoils are exposed to shock waves, which alter the pressure distribution to increase drag.
