Abstract
Six different cases of helicopter main rotor parameter
variation are considered for each of three different forward
velocities - hover, sixty knots and one-hundred fifty knots - in
order to consider the effects of the changes on the total power
required for the helicopter. The six cases included variations
in rotor radius, rotor chord, solidity, disc area, rotational
velocity and tip velocity.
Although strong positive or negative effects may be observed
at some velocities, these trends are generally not the same at
all velocities, indicating that trade-offs must be made in the
design process in order to optimize the level flight
performance.
