High Speed Flight: Subsonic Versus Supersonic Flow
In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is immersed. At speeds o…
High Speed Flight: Speed Ranges
The speed of sound varies with temperature. Under standard temperature conditions of 15 °C, the speed of sound at sea level is 661 knots. At 40,000 feet, where the temperature is –55 °C, the speed of…
Effect of Weight on Stability and Controllability
Overloading also affects stability. An aircraft that is stable and controllable when loaded normally may have very different flight characteristics w…
Effect of Weight on Aircraft Structure
The effect of additional weight on the wing structure of an aircraft is not readily apparent. Airworthiness requirements prescribe that the structure…
Effect of Weight on Flight Performance
The takeoff/climb and landing performance of an aircraft are determined on the basis of its maximum allowable takeoff and landing weights. A heavier …
