Glide angle for given lift-to-drag ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Glide Angle = atan(1/Lift-to-drag Ratio)
θ = atan(1/LD)
This formula uses 2 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)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)

Variables Used

Glide Angle - (Measured in Radian) - Glide Angle is defined as the angle made by the glide flight path with the horizontal.
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.

STEP 1: Convert Input(s) to Base Unit

Lift-to-drag Ratio: 6.61 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ = atan(1/LD) --> atan(1/6.61)

Evaluating ... ...

θ = 0.150147343396535

STEP 3: Convert Result to Output's Unit

0.150147343396535 Radian --> No Conversion Required

FINAL ANSWER

0.150147343396535 ≈ 0.150147 Radian <-- Glide Angle

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)

Glide angle for given lift-to-drag ratio Formula

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