Force of lift equation
WebMay 13, 2024 · Aerodynamic forces are mechanical forces. They are generated by the interaction and contact of a solid body with a fluid, a liquid or a gas . Aerodynamic forces are not generated by a force field , in the sense of the gravitational field ,or an electromagnetic field . For lift and drag to be generated, the rocket must be in contact … The lift equation states that lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A. L = Cl * A * .5 * r * V^2 Flow Conditions. For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift. See more Lift depends on the density of the air, the square of the velocity, the air’s viscosity and compressibility, the surface area over which the air flows, … See more One way to deal with complex dependencies is to characterize the dependence by a single variable. For lift, this variable is called the lift coefficient, designated … See more In the equation given above, the density is designated by the letter “r.” We do not use “d” for density, since “d” is often used to specify distance. In many textbooks on aerodynamics, the density is given by the Greek symbol “rho” … See more For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift.
