Preliminary Helicopter Design Decision Making Based on Flight Performance Factors

摘要

This thesis assists those evaluating helicopter design to make preliminary judgements about the feasibility of new designs. By using the computer program developed in this thesis, a designer can produce estimates for power requirements, endurance velocity, rate of climb, range velocity, hover ceiling, and service ceiling versus main rotor radius. These estimates can also be examined for the effects of changes in main rotor radius, chord, and rotational velocity.
