PARAMETRIC TRADE-OFF ANALYSIS FOR TILTING FREE PROPULSOR V/STOL AIRCRAFT IN EQUILIBRIUM TRANSITION

Abstract

An analysis for tilting free propulsor Vertical/Short Take-Off and Landing (V/STOL) aircraft in equilibrium transition is presented. Families of curves are generated in terms of nondimensional flight parameters so that the effects of aerodynamic interactions and varying geometric configurations may be studied. For known values of the ideal hover quantities, the transition characteristics, including thrust and power requirements, may be determined for specific aircraft designs. Suggestions are presented as to those characteristics which should be incorporated into the design of a tilting free propulsor V/STOL aircraft. A comparison is then made between a tilt-wing and tilt-rotor aircraft, each employing the favorable characteristics prescribed by the tradeoff study.
