Sidewash angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sidewash Angle = Vertical Tail Angle of Attack-Sideslip Angle
σ = α_v-β
This formula uses 3 Variables

Variables Used

Sidewash Angle - (Measured in Radian) - Sidewash Angle is caused by the flow field distortion due to the wings and fuselage. It is analogous to the downwash angle for the horizontal tailplane.
Vertical Tail Angle of Attack - (Measured in Radian) - Vertical Tail Angle of Attack is the angle of attack experienced by the vertical tailplane of an aircraft.
Sideslip Angle - (Measured in Radian) - The Sideslip Angle, also called the angle of sideslip, is a term used in fluid dynamics and aerodynamics, and aviation which relates to the rotation of the aircraft centerline from the relative wind.

STEP 1: Convert Input(s) to Base Unit

Vertical Tail Angle of Attack: 0.117 Radian --> 0.117 Radian No Conversion Required
Sideslip Angle: 0.05 Radian --> 0.05 Radian No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ = α_v-β --> 0.117-0.05

Evaluating ... ...

σ = 0.067

STEP 3: Convert Result to Output's Unit

0.067 Radian --> No Conversion Required

FINAL ANSWER

0.067 Radian <-- Sidewash Angle
