High Density, High Efficiency Electrical Power Generation

Fighter jets use dual starter generators that provide dc power in two channels, and also provide the mechanical power during start mode for starting the propulsion engine. A current application of the dual starter generator has two generator channels each capable of providing 80 kW power at 270 Vdc. This proposal offers application of a different generator technology to support the growing power needs, by producing 25% more power with reduced overall weight of the generator. Additionally due to better cooling techniques, the generator losses are reduced and the generator efficiency in improved. Due to the lower component count of the generator, the reliability of the generator is expected to be better and the production costa are anticipated to be lower. This proposal includes a plan to complete the design of the dual starter generator, and the associated controller, and test the system in a laboratory environment. The test results will be compared to the requirements of fighter aircraft. This will be followed by a laboratory demonstration.
