Title:
METHOD FOR OPTIMIZING THE OVERALL ENERGY EFFICIENCY OF AN AIRCRAFT, AND MAIN POWER PACKAGE FOR IMPLEMENTING SAME
Document Type and Number:
WIPO Patent Application WO/2012/025687
Kind Code:
A3
Abstract:
The invention relates to limiting the specific consumption of an aircraft by matching the sizing of the power supply to the actual power needs of the cabin pressure control system, and more generally to that of the aircraft. According to the invention, the method for optimizing the overall efficiency of the energy supplied onboard an aircraft consists of providing, in an environment located near the cabin, at least one main power-generating engine, sized so as to serve as a single pneumatic energy-generating source for the cabin and as an at most partial propulsive, hydraulic, and/or electric energy-generating source for the rest of the aircraft. The method then consists of minimizing the power differential between the nominal point ((Pn)1, (Pn)0) of the power sources when said sources are operating, and the sizing point ((Pd)0) of the non-propulsive energy contributions of said sources when the main engine has failed, by equally dividing the power contributions of the main engines and the main power generator under nominal operating conditions and in the event of a failure of a main engine.
