Yawing Moment given Rudder Deflection Solution

STEP 0: Pre-Calculation Summary

Formula Used

Yawing Moment Coefficient = Negative Yawing Moment/Dynamic Pressure at Wing*Wing Reference Area*Wingspan
C_n = N/Q_w*s*b
This formula uses 5 Variables

Variables Used

Yawing Moment Coefficient - Yawing moment coefficient is the coefficient associated with the moment that tends to rotate an airplane about its vertical (or yaw) axis.
Negative Yawing Moment - A Negative Yawing Moment is produced by positive sideslip.
Dynamic Pressure at Wing - (Measured in Pascal) - Dynamic Pressure at Wing Represents the kinetic energy per unit volume of air due to its motion.
Wing Reference Area - (Measured in Square Meter) - Wing Reference Area is the planform area, refers to the projected area of the wing, as if viewed directly from above.
Wingspan - (Measured in Meter) - The Wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip.

STEP 1: Convert Input(s) to Base Unit

Negative Yawing Moment: 11.5 --> No Conversion Required
Dynamic Pressure at Wing: 90 Pascal --> 90 Pascal No Conversion Required
Wing Reference Area: 8.5 Square Meter --> 8.5 Square Meter No Conversion Required
