HELICOPTER AERODYNAMICS WORKBOOK
Now, we've discussed how rotor blades and rotor systems work, let's investigate how they
work with a helicopter fuselage and all of the forces that come into play. For a helicopter to
remain in steady, level flight, these forces and moments must balance. These forces (figure 3-1)
exist in the vertical plane, horizontal plane, and about the center of gravity in the form of
To begin the discussion of these forces, we will discuss the power required which produces
these forces (figure 3-2).
