Dihedral angle for given sideslip velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dihedral angle = asin(Side Velocity Normal Component/Sideslip velocity)
Γ = asin(V_n/V_β)
This formula uses 2 Functions, 3 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
asin - The inverse sine function, is a trigonometric function that takes a ratio of two sides of a right triangle and outputs the angle opposite the side with the given ratio., asin(Number)

Variables Used

Dihedral angle - (Measured in Radian) - The dihedral angle is defined as the spanwise inclination of the wing with respect to the horizontal.
Side Velocity Normal Component - (Measured in Meter per Second) - Side velocity normal component is the normal component of side velocity associated with the dihedral effect.
Sideslip velocity - (Measured in Meter per Second) - Sideslip velocity is the velocity of aircraft when it sideslips.
