“…Using the fifteen-phase PMSM to directly drive the propeller, the temperature rise caused by the change of motor speed and torque demand during the whole flight is our main concern. According to the flight condition of a typical two-seater fullelectric aircraft [35], the cruising time is shortened, and the required torque and speed are obtained as shown in Fig. 10.…”

In order to not change the space vector pulse width modulation (SVPWM) control strategy during one phase fault, the five-phase six-bridge arm SVPWM fault tolerant control method for fifteen-phase permanent magnet synchronous motor (PMSM) is proposed in this paper, and the thermal stress of fifteen-phase PMSM under different fault-tolerant operations is analyzed. Firstly, the control model of the fifteen-phase PMSM based on three dq axes is established, the generation mode of the SVPWM is analyzed, and the speed and current loop PI regulators of the control system are designed. Secondly, the fault-tolerant control principle of the five-phase six-bridge arm is analyzed and compared with the hysteresis control strategy of equal amplitude and minimum stator loss. Thirdly, the 3D model of the fifteen-phase PMSM is established, the steady-state temperature and the transient temperature rise considering operating conditions under different fault tolerant operations are analyzed, and corresponding temperature rise results of the stator armature windings are compared separately. Finally, the experimental platform is established, the phase current waveforms tested under load conditions confirm the theoretical analysis of five-phase six-bridge arms and hysteresis control, and the test results of steady-state and transient temperature rise confirm the correctness of the simulation prediction.

“…The capacity for the motor and the controller needs to be large enough to satisfy the power demand during the climb phase. For safety purpose, the maximum power output of the propulsion system is determined by the power demand of the climb phase [10]. Power demand during the climb phase is the highest among four phases, which can be approximately 3 to 4 times of the power demand during the cruise phase.…”

“…Given the fact that the motor and the controller are operating at high efficiency during the climb phase, their impact to the energy consumption of the propulsion system can be ignored [19]. The power of the propulsion system during the cruise phase P cr is: (10) where T cr is the thrust of the aircraft during the cruise, v c is the cruise speed. The thrust required during the cruise phase is equal to the resistance it received, therefore:…”

As a key component of electric aircrafts, electric propulsion systems provide sufficient thrust for electric aircrafts. By improving its efficiency, the power consumed by the electric propulsion system can be reduced. Therefore, the maximum range of electric aircrafts, which is limited by the energy density of batteries, can be further increased. Upon investigating the power demand and the energy consumption of the electric propulsion system in each flight profile phase of fixed pitch propellers electric aircrafts, this paper proposes a novel energy efficiency optimization method tailored for fixed pitch propeller electric aircrafts by minimizing the total energy consumption of one flight over the maximum efficiency of the propeller. The proposed method is adopted to the design of a fixed pitch propeller electric aircraft. Experimental results suggest that the tested fixed propeller electric aircraft designed can achieve better energy efficiency while reducing energy consumption by more than 10%.

“…Boeing also flew a motor-glider using a PEMFC system hybridized with Li-ion batteries [13]. The ENF-ICA project led by Politecnico di Torino demonstrated an aircraft powered by a fuel cell and Li-ion batteries [15]. Studies on the effects of air pressure decrease due to altitude on the performances of PEMFC systems have been led [2,16] and conclude to a power and efficiency decline as altitude is increased.…”
