Mission-Influenced Optimized Hybrid Propulsion Architectures for Aircraft

点击翻译按钮获取中文摘要

Electric aircraft propulsion has the potential to revolutionize the aerospace industry, by reducing the fuel burn,**emissions, noise, and improve the aircraft performance. The interest for this technology has increased in the**last couple of years with the development of vertical take off and landing aircraft with a large number of**propulsors and very short missions. While the battery technology matures, hybrid-electric propulsion is seen as**an enabler to improve range, while taking advantage of some of the benefits from electric propulsion. In a**parallel-hybrid architecture, an electric motor is used to add or extract power from a conventional gas turbine**and its propulsion system. In a series-hybrid architecture, the propulsion system is driven by an electric motor,**and the electricity is provided by a generator and a gas turbine.**The focus of this research project is to compare parallel-hybrid and series-hybrid propulsion architecture for a**variety of conventional aircraft, including a regional transport aircraft (40 pax), a commuter aircraft (8 pax),**and a modern rotorcraft. For each type of aircraft, each type of propulsion architecture will be optimized and**compared to minimize fuel burn or direct operating cost for a predefined mission given today's technologies**and future technologies. A system-level mission simulation will be developed to analyze the aircraft**performance throughout each mission phase. While there is a target mission defined in terms of range or**endurance, the optimization process will also vary the mission profile, including cruise altitude and the**climb/descent profile to maximize the benefits of the hybrid propulsion powertrain.**This research project will benefit the industrial partner, with the identification of the most promissing market**for the development of hybrid propulsion for more conventional aircraft
