“…Furthermore, specifications, such as reliability and power density, became ever more critical. For these reasons, a general world-wide move towards AC generation was observed [13,30], which reveals several advantages compared to DC generation. First of all, a significant improvement is achieved in terms of power density (i.e.…”

“…A frequency of 240Hz was suggested at the beginning of 1940s, for keeping motors and transformer weight to a practical minimum [30]. Obviously, this choice was also dictated by the magnetic materials available at that time.…”

“…Based on respective needs and requirements, the Army Air Corps in 1943 chose 400Hz as the standard frequency, since it appeared to be more feasible for the generator speed (e.g. 12000rpm for 4-pole machines) [30,31]. This 'standard' of 115/200V at 400Hz frequency has been made mandatory for use by the US Air Force in 1959 (MIL-STD-704) and has remained with us to this day.…”

Abstract-The constant growth of air traffic, the demand for performance optimization and the need for decreasing both operating and maintenance costs have encouraged the aircraft industry to move towards more electric solutions. As a result of this trend, electric power required on board of aircraft has significantly increased through the years, causing major changes in electric power system architectures. Considering this scenario, the paper gives a review about the evolution of electric power generation systems in aircraft. The major achievements are highlighted and the rationale behind some significant developments discussed. After a brief historical overview of the early DC generators (both wind-and engine-driven), the reasons which brought the definitive passage to the AC generation, for larger aircraft, are presented and explained. Several AC generation systems are investigated with particular attention being focused on the voltage levels and the generator technology. Further, examples of commercial aircraft implementing AC generation systems are provided. Finally, the trends towards modern generation systems are also considered giving prominence to their challenges and feasibility.

“…Currently the highest commercial battery energy storage has energy density range from 150 to 250 Wh/kg; however, an ideal energy density in these batteries would be at least 500 Wh/kg. In addition, to improve energy density, long battery life-cycles and better recharging speeds are also essential for battery-powered aircraft [10].…”

Electric and hybrid-electric aircraft propulsion are rapidly revolutionising mobility technologies. Air travel has become a major focus point with respect to reducing greenhouse gas emissions. The electrification of aircraft components can bring several benefits such as reduced mass, environmental impact, fuel consumption, increased reliability and quicker failure resolution. Propulsion, actuation and power generation are the three key areas of focus in more electric aircraft technologies, due to the increasing demand for power-dense, efficient and fault-tolerant flight components. The necessity of having environmentally friendly aircraft systems has promoted the aerospace industry to use electrically powered drive systems, rather than the conventional mechanical, pneumatic or hydraulic systems. In this context, this paper reviews the current state of art and future advances in more electric technologies, in conjunction with a number of industrially relevant discussions. In this study, a permanent magnet motor was identified as the most efficient machine for aircraft subsystems. It is found to be 78% and 60% more power dense than switch-reluctant and induction machines. Several development methods to close the gap between existing and future design were also analysed, including the embedded cooling system, high-thermal-conductivity insulation materials, thin-gauge and high-strength electrical steel and integrated motor drive topology.

“…Since the use of direct current EPS, which was also the first system used on board, was no longer an option due to weight, volume, and power losses on the electrical distribution network, the studies, and research carried out in the early '40s found that an alternating current EPS at a frequency of 400 Hz would be optimal precisely because of the reduced weight for motors and generators without a significant increase in wire weight [1].…”

Although recent developments in aircraft electrical technology have had a significant impact on aircraft electrical power systems (EPS), thus reminding the development and production of more electric aircraft (MEA), but also important steps in the development of all-electric aircraft (AEA), still the EPS of the latest aircraft produced by the two big players in the market, the Neo series from Airbus and the NG or Max from Boeing respectively, is completely traditional – a constant speed constant frequency (CSCF) system. Thus, for an alternating current one, it is composed of the power source – the integrated drive generator (IDG), the command and control system – the generator control unit (GCU), the transmission and distribution system, the protection system – the CBs (circuit breaker) and electrical loads. This paper presents the design and simulation of an aircraft EPS using Simulink’s Simscape package, a MATLAB program, and for the first time in the specialized literature, a model of the constant speed drive (CSD) generated with the same program is used to drive the synchronous generator (SG) in the IDG.
