HESCOMP. The Helicopter Sizing and Performance Computer Program. User's Manual. Revision 2.
Abstract
The purpose of the HESCOMP computer program is to provide the means for a rapidly developing helicopter sizing and mission performance data. The program can be used to define design requirements, such as weight breakdown, required propulsive power, and physical dimensions of aircraft which are designed to meet specified mission requirements. It is also useful in sensitivity studies involving both design trade-offs and performance trade-offs. HESCOMP may be used for sizing helicopters for which the type of aircraft and the mission profile are specified. Alternatively, it may be used for mission calculations for aircraft for which sizing details (gross weight, fuel available, engine power and fuel consumption, etc.) are known. As a combination of these two capabilities, it may be used first to size a helicopter for a given mission and then calculate the off-design point performance for other missions. It contains size trends equations which reflect the variation of helicopter dimensions with gross weight, detailed statistical weight trends equations, a routine for sizing of engines to match airframe requirements, a comprehensive library of engine cycle data, a library of rotor cycle data, and a variety of optional procedures for calculating rotor and propeller (cruise only) performance. The program can be used to study any single, tandem, or coaxial pure winged, compound, or auxiliary propulsion helicopter.
