Abstract

Performing a temporary shutdown of one engine of a twin-engine-powered helicopter in suitable situations during a flight mission saves fuel. Quantifying the potential fuel savings is a relevant item for both economic and environmental reasons. Before performing extensive and costly flight tests relevant simulations should be done. Therefore, in a first step, a cost-effective and detailed simulation model of the BO 105 for normal flight operations has been developed in MATLAB/Simulink, as part of a diploma thesis. The purpose was not to research new helicopter simulation methods but to select appropriate and approved methods to ensure a proper state-of-the-art simulation model. Besides the flight dynamics model, it includes a simple flight control system and an autopilot as well as a flight mission management system. In conjunction with the existing Allison 250-C20B simulation model of the Institute for Flight Propulsion, self-composed flight missions can be performed. The comprehensive model was validated with flight test data from the DLR, thereby demonstrating its prospects.
