Effects of the actively morphing root chord and taper on helicopter energy

Abstract

Purpose

The purpose of this paper presents the effects of actively morphing root chord and taper on the energy of the flight control system (i.e. FCS).

Design/methodology/approach

Via regarding previously mentioned purposes, sophisticated and realistic helicopter models are benefitted to examine the energy of the FCS.

Findings

Helicopters having actively morphing blade root chord length and blade taper consume less control energy than the ones having one of or any of passively morphing blade root chord length and blade taper.

Practical implications

Actively morphing blade root chord length and blade taper can be used for cheaper helicopter operations.

Originality/value

The main originality of this paper is applying active morphing strategy on helicopter blade root chord and blade taper. In this paper, it is also found that using active morphing strategy on helicopter blade root chord and blade taper reasons less energy consumption than using either passively morphing blade root chord length plus blade taper or not any. This causes also less fuel consumption and green environment.
