Strip analysis procedure used to calculate effect of twist and plan form taper, on rotor efficiency in hovering; comparison made for rotors of equal solidity, solidities of tapered blades being computed by means of equivalent chord; 5% increase is shown over rectangular blades if both linear twist (-8° to -12°) and taper (ratio of root to tip chords of 3) are applied.
