A Computer Model for Determining Weapon Release Parameters for a Helicopter in Non-Accelerated Flight.

Abstract

A mathematical model capable of computing flight path and orientation data for helicopters having a single main rotor and a vertical tail rotor is presented. The model calculates power level and contro angles in steady (trimmed) flight for ascending, level, or descending flight paths. Provisions are included for simulating a fixed wing, auxiliary thrust, and a movable horizontal tail whose incidence angle is linked to the main rotor longitudinal cyclic control. The model is coded in Fortran Extended to run on the CDC 6700 Computer system. Output from this model is used in the generation of aiming data for the delivery of unguided ordnance. (Author)
