Abstract

This paper aims to offer a simultaneous design approach for helicopter having swept anhedral blade tip shape and helicopter flight control system (HFCS) to minimize controller cost.Design/methodology/approachBy considering previously stated offer, control-oriented models and a stochastic optimization method are applied to minimize controller cost of the HFCS.FindingsUsing simultaneous design approach for helicopters having blade tip swept and blade tip anhedral causes considerably less control effort than the helicopters not benefiting this related design approach.Practical implicationsSimultaneous design approach for helicopters having blade tip swept and blade tip anhedral is applicable to consider fuel economy.Originality/valueOne important novelty of this paper is using simultaneous approach for determining optimum shape of blade tip swept and anhedral. Another considerable novelty of this paper is also using a stochastic optimization method called simultaneous perturbation stochastic approximation for previously mentioned purpose. In this paper, it is also reached that using simultaneous design approach for swept anhedral helicopter blade tip shape and HFCS causes less control effort than the helicopters not using this approach. This leads to less fuel consumption and green environment.
