ABSTRACT: Electrical motors are rapidly replacing hydraulic motors in flight actuators for aircraft applications. In hydraulic systems, accumulators are used to store regenerative energy from the actuators as well as to supply peak energy demands of these actuators in response to flight control system demands. No electrical analog (Electrical Accumulator Unit) exists in production, although some prototype hardware has been demonstrated to store/supply transient electric energy (~100 Kwatt spikes). Advanced EAU designs merge the emergency power function (battery energy storage) with the transient electrical energy function. Working with the battery, the resultant Dual Mode EAU (DMEAU) would have the following functions: emergency power, transient energy supply/storage, battery charging, engine starting and 270 VDC power generation. The DMEAU would meet the requirements of the current BCCU space . For this proposal, an advanced EAU breadboard converter will be fabricated and tested to expected aircraft actuator transient loads with an emulated energy storage battery BENEFIT: Fabrication of an advanced packaged EAU converter will increase the technology readiness level of the DMEAU. The combined outcomes of weight savings and increased vehicle capability will spur the application of Dual Mode Electrical Accumulator Units to several thousand high performance aircraft.
