Catapults and Taking Off from an Aircraft Carrier | HowStuffWorks

The catapult officer carefully monitors the pressure level so it''s just right for the particular plane and deck conditions. If the pressure is too low, the plane won''t get moving fast enough to take off, and the catapult will throw it into the ocean. If there''s too much pressure, the sudden jerk could break the nose gear right off.

OverviewMain componentsPhysical characteristicsApplicationsComparison to electric batteriesSee alsoFurther readingExternal links

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) 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 increase in the speed of th
