Flight Simulation of the Model 347 Advanced Tandem-Rotor Helicopter

Abstract

The basic purpose of the study was to define important flight control system design and handling qualities criteria for moving loads along beneath tandem-rotor heavy lift helicopters. The principal study effort involved flight simulation of the Model 347 advanced tandem-rotor helicopter. Methodologies used in developing data included theoretical analyses, acquisition and evaluation of wind tunnel and flight test data, derivation of motion equations, analysis of sling load carrying problems, development of the dynamics of a container slung beneath a tandem-rotor helicopter, and the actual flight simulation of a Model 347 helicopter with external loads using Northrop's advanced large-amplitude moving-base simulator and its associated hybrid computers.
