can remove waste heat from the aircraft EMAs components and transport the heat to the entire bay surfaces. The entire bay surfaces area can act as a heat sink, thus avoiding the need to mount a condenser or cold plate to the bay wall. The EMAs waste heat is generated at the motor, associated control electronics (E-box), gear box, and drive train. The major heat generation source is the motor and it has fins and a cooling fan attached. The fan is structurally integrated with the motor, but is powered and controlled independently with temperature sensors so that the fan is turned on whenever a certain temperature of the actuator is exceeded [2,3]. The drive train and gear box are cooled by recirculating air within the bay. Enclosing the fins with an outer shell creates an annular duct for air to pass through. This way the forced

Power management has become a significant concern that must be addressed before the realization of an allelectric aircraft. Electromechanical actuators (EMAs) for flight control surfaces are of special concern. They demand high power with highly variable duty cycles and are extremely flight-critical. Dynamic, nonlinear, lumped-element modeling of permanent magnet motors provides the means to simulate with high fidelity and speed the behavior of EMAs over any given mission profile. This paper focuses on a successful technique of dynamic, nonlinear inductance modeling which is at the heart of modeling the whole EMA.

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.
