A Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics. Part 2. User's Manual

Wayne R. Johnson

Open full text 24 citations

Abstract

The use of a computer program for a comprehensive analytical model of rotorcraft aerodynamics and dynamics is described. The program calculates the loads and motion of helicopter rotors and airframe. First the trim solution is obtained, then the flutter, flight dynamics, and/or transient behavior can be calculated. Either a new job can be initiated or further calculations can be performed for an old job.
