WebIn aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under given flight conditions. The L/D ratio for any given body will vary according to these flight conditions. For an aerofoil wing … WebThe thrust in the rocket is equal to T = m ˙ V (Assuming the rocket nozzle is operating at its optimum condition) The Thrust is a strong function of the exhaust velocity V = 2 γ R ∘ T ∘ ( γ − 1) μ ( 1 − ( P e P c) γ − 1 γ) This equation gives the exhaust velocity of the rocket WebMay 16, 2024 · Bottom line. Taking off from hot and high airfields can seriously affect the performance of all aircraft. When departing in such conditions, pilots must pay careful attention to the conditions and adjust the aircraft weight accordingly. Taking off at too heavy a weight could have serious implications for the safety of the aircraft. small section carpet rug
