Abstract

An improved aircraft (10) is provided through the use of an improved hydraulic system (12) which incorporates a flywheel peaking unit (28) that stores energy during periods when the aircraft is demanding less hydraulic power than the remainder of the hydraulic system is capable of producing, and utilizes that stored energy to augment hydraulic power being provided by the remainder of the hydraulic system when the aircraft is demanding more hydraulic power than can be produced by the remainder of the hydraulic system. The flywheel peaking unit allows use of existing Ram Air Turbines (58) on new aircraft requiring more emergency hydraulic power than previous aircraft, thereby eliminating unwanted cost and time in developing a new aircraft.
