STEP 0: Pre-Calculation Summary

Formula Used

Lift-to-drag Ratio = 1/tan(Glide Angle)
LD = 1/tan(θ)
This formula uses 1 Functions, 2 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Lift-to-drag Ratio - The Lift-to-drag ratio is the amount of lift generated by a wing or vehicle, divided by the aerodynamic drag it creates by moving through the air.
Glide Angle - (Measured in Radian) - Glide Angle is defined as the angle made by the glide flight path with the horizontal.

STEP 1: Convert Input(s) to Base Unit

Glide Angle: 0.15 Radian --> 0.15 Radian No Conversion Required

Weight of Glider

Go Weight Of Glider = Lift Force*cos(Glide Angle)+Drag Force*sin(Glide Angle)

Glide angle

Go Glide Angle = atan(Drag Force/Lift Force)

Lift Force for given Glide Angle

Go Lift Force = Drag Force/tan(Glide Angle)

Drag for given Glide Angle

Go Drag Force = Lift Force*tan(Glide Angle)

Glide angle for given lift-to-drag ratio

Go Glide Angle = atan(1/Lift-to-drag Ratio)

Lift-to-drag ratio for given glide angle

Go Lift-to-drag Ratio = 1/tan(Glide Angle)

Lift-to-drag ratio for given glide angle Formula

Lift-to-drag Ratio = 1/tan(Glide Angle)
LD = 1/tan(θ)
