Synopsis
:
This paper
describes the mathematical modelling, analysis and simulation study of a
helicopter with an external slung load system. The primary feature of the
proposed model is the use of a helicopter model that consists of a six-degree
of freedom and combined with a three-dimensional motion load model. Considering
the two models, a mathematical model for a helicopter carrying an external load
is obtained. The combined system model can be used for stability analysis and
controller development to improve flight handling quality and system
performance. Stability analysis of the system was carried out via simulation.
Simulation results revealed that the stability of the helicopter is
significantly reduced due to the presence of an underslung load.
