Since … WebMay 1, 2024 · Using the definition of the lift coefficient. (4.5) C L = L 1 2 ρ V ∞ 2 S. and the assumption that lift equals weight, the speed in straight and level flight becomes: (4.6) V = 2 W ρ S C L. The thrust needed to maintain this speed in straight and level flight is also a function of the aircraft weight. Since T = D and L = W we can write.

WebFor those powerplants that experience a decay in thrust with an increase in altitude, the effect on the net accelerating force and acceleration rate can be approximated by assuming a direct variation with density. Actually, this assumed variation would closely approximate the effect on aircraft with high thrust-to-weight ratios.
