Abstract: With the proliferation of electromagnetic launch systems presently being designed, built, or studied, there appears to be no limit to their application. One of the intriguing applications is electromagnetically catapulting aircraft from the deck of an aircraft carrier.
The US Navy had foreseen the substantial capabilities of an electromagnetic catapult in the 1940s and built a prototype. However, it was not until the recent technical advances in the areas of pulsed power, power conditioning, energy storage devices, and controls gave credence to a fieldable electromagnetic aircraft launch system.
The EMALS energy-storage system design accommodates this by drawing power from the ship during its 45-second recharge period and storing the energy kinetically using the rotors of four disk alternators; the system then releases that energy (up to 484 MJ) in 2–3 seconds.
China developed an electromagnetic catapult system in the 2000s for aircraft carriers, but with a different technical approach. Chinese adopted a medium-voltage, direct current (DC) power transmission system, instead of the alternating current catapult system that United States developed.
Its main advantage is that it accelerates aircraft more smoothly, putting less stress on their airframes. Compared to steam catapults, the EMALS also weighs less, is expected to cost less and require less maintenance, and can launch both heavier and lighter aircraft than a steam piston-driven system.
The Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy.

Abstract: A novel energy storage flywheel system is proposed, which utilizes high-temperature superconducting (HTS) electromagnets and zero-flux coils.
flywheel energy storage system typically works by combining a high-strength, high-momentum rotor with a shaft-mounted motor/generator. This assembly is contained inside a vacuum / containment vessel and operates normally in a non-contact fashion with magnetic bearings acting as a suspension system.
The basic concept of a flywheel electrical system is noted in figure 1. Other common power electronic circuits invert power from the motor/generator to line voltages and frequencies. 1 Funded in part by the Energy Storage Systems Program of the U.S. Department Of Energy (DOE/ESS) through Sandia National Laboratories (SNL).
With the high energy requirement for the flywheel system, the bearing loss can be great enough to significantly reducing the overall system efficiency. The 5 kWh / 100 kW FESS utilizes the hybrid HTS magnetic bearings .
Recharging can be done with essentially the same power switching electronics that are used for the discharge, except that the timing of currents in the motor/generator stator windings is adjusted to push the flywheel back up to high speeds. Once at high speed, the flywheel system can idle thus storing energy and acting as a battery.
