Energy and Power System Design and Test Verification for Electric VTOL

<div class="section abstract"><div class="htmlview paragraph">Electric technology has gradually changed the form of energy use in transportation. Electric vertical take-off and landing aircraft (eVTOL) will become an important means of transportation in the future, bringing significant changes to urban transportation and providing a more convenient and comfortable travel experience for people. eVTOLs are being extensively researched and developed by the global aviation industry as well as by many innovative technology companies. In this paper, we focus on the system design and testing of the four-axis and eight-propeller eVTOL. The overall parameters of the aircraft are defined, and the energy and power architecture design and analysis are carried out. Carry out the hybrid power supply design of lithium battery and fuel cell, and complete the parameter matching design of power system. The lithium battery and fuel cell hybrid power supply, single propeller test, dual propeller test, system integration verification were carried out, and finally the bench test was carried out to verify the feasibility of the scheme.</div></div>
