Wings of aspect ratio 2.7 having diamond, circular-arc, and blunt-trailing edge airfoil sections were tested. Pressures were measured on the base of the blunt-trailing-edge airfoil which had a rectangular The lift coefficient is a number that aerodynamicists use to model all of the complex dependencies of shape, inclination, and some flow conditions on lift. This equation is simply a rearrangement of the lift equation where we solve for the lift coefficient in terms of the other variables. The lift coefficient Cl is … See more For very low speeds (< 200 mph) the compressibility effects are negligible. At higher speeds, it becomes important to match Mach numbers between the two cases. Mach number is the ratio of the velocity to the speed … See more Similarly, we must match air viscosity effects, which becomes very difficult. The important matching parameter for viscosity is the Reynolds number. The Reynolds number expresses … See more
WebJul 28, 2024 · Lift Coefficient For given air conditions, shape, and inclination of the object, we must determine a value for Cd to determine drag. Determining the value of the drag coefficient is more difficult than determining the lift coefficient because of the multiple sources of drag. WebLift coefficient is illustrated in Fig. 1.23 for an airfoil, i.e., a two-dimensional (infinite-span) wing. Considering first the full curve (a), which is for a moderately thick (13%) section of …
WebFeb 5, 2024 · Cl – This is Coefficient of Lift. It’s a tricky value because it changes with different shapes of wings, how fast you’re going, the wing angle, and turbulence. For the time being, you can use a value of 1. Multiplying by 1 is easy, and I’ll explain later why this is also a reasonable value. V^2 – Velocity in feet per second, squared.
