Abstract

This chapter presents a preliminary analysis of fault tolerance, availability and performance assessment of the two promising options of the hybrid-electric traction drive version for the helicopter, which can be treated as multi-state system, where components and entire system in general case have an arbitrary finite number of states corresponding to the different performance rates. The performance rate (output nominal power) of the system at any time instant is interpreted as a discrete-state continuous-time stochastic process. In the present chapter, the Lz-transform is applied to a real multi-state hybrid-electric traction drive version for the helicopter system that is functioning under various stochastic demands and its availability and performance is analyzed. It is shown that Lz-transform application drastically simplifies the availability computation for such a system compared with the straightforward Markov method.
