This work proposes two alternative analytical models to evaluate the ac losses of High-Temperature Superconducting (HTS) tapes during their hysteretic and resistive modes. These models intend to extend the application range of state-of-the-art analytical models for current values higher than the critical one, i.e., for the resistive state, and to correctly predict the ac losses during the transition between the hysteretic and resistive modes. Two analytical models are proposed, one considering an extension of the Norris model for the HTS tape’s resistive mode and the other based on a Sigmoid function to characterize the hysteretic losses and their smooth transition to the resistive mode. Analytical models capable of estimating ac losses of superconducting (SC) tapes are an important tool for the design of complex SC systems, such as SC fault current limiters, SC electrical machines and SC cables. The proposed models are validated experimentally, for a 1st generation BSCCO tape and a 2nd generation ReBCO tape. Finite element simulation is also carried out to verify the accuracy of the proposed models. Results show that the proposed Extended-Norris model presents some deviation at the transition between the hysteretic and resistive modes, while the Sigmoid model presents very accurate results for the whole spectrum of applied current. Also, the parameters of the Sigmoid models are independent of the tape geometry.

“…Conventional materials and systems architectures are approaching their performance limits and cannot meet the dual requirements for the weight reduction and power increase of the future generation of aircraft. An HTS generator with an accompanying aviation power system is one of the most promising options [5][6][7][8][9].…”

Aircraft electrification has become a tendency with demands for low carbon emissions and high electrical load capacity nowadays. Aircraft are especially strict with onboard weight; as a result, high-temperature superconducting (HTS) electrical machines are drawing attention for airborne applications due to their potential for a significant increase in power density. In this study, a feasible scheme of a hybrid-HTS airborne synchronous generator was proposed to fulfill the requirements of a small aircraft (with fewer than eight seats and a maximum range of about 1000 km). The full design from top to bottom is described. The output characteristics and metallic and superconducting AC losses were calculated based on the finite element method. The power grade of 1 MW was obtained, with a power density of 9.27 kW/kg and an efficiency of 98.73%. Furthermore, the performance of the machine was optimized using the Taguchi method. The preliminary design demonstrated the possibility and benefits of hybrid-HTS machines for airborne applications.
