Hinge Moment Calculator by Mohit Kudal

Hinge Moment is defined as the force required deflecting a control surface. In small, relatively slow airplanes, hinge moments are not very large; pilots move the controls with ease. But as control surfaces get larger and speeds get higher, Hinge Moments Grow Rapidly.

Where:-

ρ is the Density

Se is the Elevator Area

Ce is the Elevator Chord

Vt is the Velocity at Tail section

CH is the coefficient of Hing Moment
