How to calculate best glide speed
In 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. Web6 feb. 2016 · What I discovered is that the changes in the various V-speeds aren’t equally relative to aircraft weight changes. For example, the Columbia’s stall speed and any v-speed related to it changes 1.25 knots per 100-pound change in aircraft weight. Maneuvering and Best Glide speeds change 2.3 knots and 1.3 knots respectively per …

Web11 feb. 2016 · Every aircraft will have it's own best glide speed, based on lift, drag and its wing loading. For example a Tiger Moth will have a best glide speed, but 75 knots is 6 knots above it's cruise speed. Same with the Aermacchi MB-326H. It has a best glide speed, but 75 knots is 4 knots below its stall speed.

WebBest glide velocity is calculated using the following equation. TAS (true airspeed in feet per second) is the velocity of the aircraft relative to the surrounding air mass. T A S b g = 2 W ρ S × [ 1 4 C D 0 2 + C D 0 π e A cos 2 ϕ] 1 4 TAS_bg = sqrt ( (2*W)/ (rho*S) ) ... * ( 1./ ( (4*C_D0.^2) + (C_D0.*pi*e*A* (cos (phi)^2)) )).^ (1/4); % TAS, fps
WebDrag curve. The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag.
