“…When the electric propulsion system is used, most of the noise is generated by the interaction of the external components of the aircraft and the interaction between the propeller and the air. This shows that the use of electric propulsion has a significant noise reduction effect for propeller aircraft [3].…”

At present, the air traffic becomes more and more important to people’s daily life and the aviation industry has exposed to many problems to be solved. Now, the air bus have become one of the most significant way of transportation and its high fossil fuel costs and low efficient overwhelmed people. Electric planes are seen as one of the solutions because many advantages they have although there still exist lots of difficulties. This article explores the advantages of electric aircraft: the reason why it is fabricated and the problems along with the process and what the future is be like. This paper represents many factors of the all-electric plane’s edges like the efficiency and the environmental friendliness. The study sums up a comprehensible conclusion about this transport. As for the difficulties, the essay also describes the electric propulsion system of an all-electric jet and analyses the reasons why it has not yet been successfully commercialized including the specific energy of the battery, capacity, temperature and other problems. People will focus on them in the future and this report will provide some information. This article shows that while there are still too many difficulties for scientists to make a practical one, people have made some breakthrough through past few years, and people will soon fabricate the real one.

“…Siemens developed a 260 kW PM motor for the Extra 330LE aerobatic aircraft. The lightweight propulsion system helped the Extra 330LE set a world record for the shortest climb time [26]. Airbus and Rolls-Royce have collaborated to develop the E-Fan X, the world's largest hybrid electric aircraft, which is based on the BAe 146 RJ100, replacing one of the four engines with a 2 MW PMSM; the E-Fan X has now passed wind tunnel testing [23].…”

As the electrification process of aircrafts continues to advance, the propulsion motor system, as its core component, has received more attention and research. This paper summarizes and analyzes the development status, research focus and typical cases in this field in recent years. Firstly, it analyzes the basic structure and principle of five common motors, summarizes the current status of their respective applications in electric aircrafts, and compares them to determine the most suitable type of motor for use as a propulsion motor, focusing on various performance indexes. Then, the optimized design of propulsion motors is generally divided into two categories, namely high power density and fault tolerance. Starting from the basic relationship equation of motor design, the basic method to improve the power density of motors is pointed out; at the same time, according to the basic principles and objectives of the fault tolerance of motors, the fault tolerance design is divided into two aspects, namely the redundant design and the design to improve the fault tolerance capability. Finally, this paper summarizes the current development status of the propulsion motor system and the existing problems and points out the main development direction of this field in the future, so as to provide reference for the further development of the electric propulsion system of aircraft.

“…It is perceived that All-Electric aircraft have already been deployed in various applications, including the drones and unmanned aircraft [8]. Moreover, in the realm of manned aircraft, there are some ambitious projects such as E-Fan, Extra 330 and Accel with the objective of fully electrifying the propulsion systems of commercially-sized passenger aircraft [9][10]. The propulsion machine is a critical technology for All-Electric aircraft as it provides the necessary propulsion power, directly impacting the reliability and ight capabilities.…”

In this paper, three typical permanent magnet machines for All-Electric aircraft propulsion are designed, optimized and compared. Firstly, the necessary performances are determined based on the requirements of high power/torque density and an aircraft with a maximum takeoff weight of 1500 kg. The initial structures of interior permanent magnet synchronous (IPM) machine, vernier permanent magnet (VPM) machine and ux-switching permanent magnet (FSPM) machine are designed with identical stator radius and rotor shaft length. Then, parametric sensitivity analysis and multi-objective particle swarm are combined as an optimization methodology to optimize these machines. Based on the nite element analysis, the electromagnetic performances such as no-load airgap ux density harmonic spectrum, cogging torque, average output torque, losses, e ciency and power factor etc. are generally compared and analyzed. Subsequently, the discussions are carried out, where the strength and weakness of these three machines are concluded and the future prospects are suggested. Finally, it is concluded that if effective measures are implemented to reduce the permanent magnet eddy current loss and improve the power factor, the VPM machine would be the most suitable choice among these machines for All-Electric aircraft propulsion.
