The E-Flight design team has reached a major milestone in the development of the E-Flight Electric Powerplant System’s Main Controller Unit (MCU) and Integrated Motor and Switching electronics (IMS). The E-Flight design team has been running the system at high voltage and amperage power inputs with a large bank of lead-acid batteries, simulating power levels to eventually be provided by the aircraft’s Battery Containment Unit (BCU) containing Lithium Polymer batteries.
On December 4, 2008 the E-Flight system was successfully run under load with a test club propeller achieving 2800 RPM, a major benchmark RPM goal demonstrating the MCU and IMS systems’ ability to provide the power necessary for flight (see video, above-right).
