“…However, the pumping power through the system was ignored. Since electromagnetic actuators (EMAs) are of special concern in the thermal management of MEA, a nonlinear, lumped-element, integrated modeling of a PM motor used in an EMA was established in [116]. A desired position profile, a load force profile, and an environmental temperature profile are taken as the inputs for this model.…”

This paper presents a review of the electrical and electronic technologies investigated in moreelectric aircraft (MEA). In order to change the current situation of low power efficiency, serious pollution, and high operating cost in conventional aircraft, the concept of MEA is proposed. By converting some hydraulic, mechanical, and pneumatic power sources into electrical ones, the overall power efficiency is greatly increased, and more flexible power regulation is achieved. The main components in an MEA power system are electrical machines and power electronics devices. The design and control methods for electrical machines and various topologies and control strategies for power electronic converters have been widely researched. Besides, several studies are carried out regarding energy management strategies that intend to optimize the operation of MEA power distribution systems. Furthermore, it is necessary to investigate the system stability and reliability issues in an MEA, since they are directly related to the safety of passengers. In terms of machine technologies, power electronics techniques, energy management strategies, and the system stability and reliability, a review is carried out for the contributions in the literature to MEA. INDEX TERMS More-electric aircraft, machine technologies, power electronics techniques, energy management strategies, system stability and reliability.

“…The thermal network analysis provides a rapid tool for predicting thermal distribution without increasing drastically the complexity of the model implementation. For example, Woodburn et al 126 described a lumped-element model of the permanent magnet motor in the EMA system. The parameters, such as non-linear inductance, thermal resistances, Table 6.…”

Conventional hydraulic actuators in aircraft systems are high maintenance and more vulnerable to high temperatures and pressures. This usually leads to high operating costs and low efficiency. With the rapid development of More/All Electric technology, power-by-wire actuators are being broadly employed to improve the maintainability, reliability, and manoeuvrability of future aircraft. This paper reviews the published application and development of the airborne linear electromechanical actuator. First, the general configuration, merits, and limitations of the gear-drive electromechanical actuator and the direct-drive electromechanical actuator are analysed. Second, the development state of the electromechanical actuator testing systems is elaborated in three aspects, namely the performance testing based on room temperature, testing in a thermal vacuum environment, and iron bird. Common problems and tendencies of the testing systems are summarized. Key technologies and research challenges are revealed in terms of fault-tolerant motor, high-thrust mechanical transmission, multidisciplinary modelling, thermal management, and thermal analysis. Finally, the trend for future electromechanical actuators in More/All Electric Aircraft applications is summarized, and future research on the airborne linear electromechanical actuators is discussed.

“…All these parts are heattransfer media with heat sources. The following assumptions are made before calculation [8][9][10][11]: (a) all parts inside the mechanism were isothermal bodies of uniform temperature rises, (b) all parts are cooled down naturally, and (c) air temperature of the external environment is constant. Cross-section structure of the PMSM is shown in Figure 2.…”

Due to serious power loss and heating caused by compact volume and high power density of high power electromechanical actuator (EMA), thermal analysis is becoming the key aspects in its design optimization. Numerical calculation method is proposed to calculate the electrical loss, iron core loss and drive chain mechanical loss in EMA. An equivalent thermal network model based on lumped parameters is established, with the acquisition of heat transfer matrix equation of all network nodes. Temperature rise of each part of the EMA is obtained by solving the equation. By comparison of simulated temperature rise in rated operating condition with test results, the accuracy of the model is verified. Then temperature rise simulation of EMA under simulated actual flight condition is carried out, with the results showing positive guidelines in the optimization design of EMA systems.
