Gerald R. Ford-class aircraft carrier

The Gerald R. Ford-class nuclear-powered aircraft carriers are currently being constructed for the United States Navy, which intends to eventually acquire ten of these ships in order to replace current carriers on a one-for-one basis, starting with the lead ship of her class, Gerald R. Ford (CVN-78), replacing Enterprise (CVN-65), and later the ...

Flywheel energy storage

Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly results in an …

The Status and Future of Flywheel Energy Storage

Indeed, the development of high strength, low-density carbon ﬁber composites (CFCs) in the 1970s generated renewed interest in ﬂywheel energy storage. Based on design strengths typically used in commercial ﬂywheels, s. max/r is around 600 kNm/kg for CFC, whereas for wrought ﬂywheel steels, it is around 75 kNm/kg.

Optimal power system design and energy management for more electric aircraft…

Meanwhile, the H 2 efficiency is further improved to 43.4% and 46.8%. With the optimal HESS size, more energy storage capacity can be used to ameliorate the working area of the FC system. As a result, the average FC anti-aging performance and H 2 efficiency can be further improved by 19.1% and 8.1% within two voyages.
