Abstract:

Aerospace electrical power demands have been growing due to an increased amount of electrical load onboard aircraft. This increased load has come about as electrical power sources for various aircraft subsystems, such as pumps, compressors and flight controls, replace mechanical power sources. The main source of electrical power on an aircraft is a generator. The nature of emerging power demands on an aircraft causes increased temperatures and complexdynamic loads many contemporary generators are not necessarily designed to repeatedly tolerate such phenomena. Due to the need for high amounts of reliable electrical power among future aircraft, future generators should be designed for reliability, stability, power density and long-term durability. The objective of this thesis project was to determine if generator sizing techniques can be calculated to a reasonable accuracy for preliminary machine design optimization and analysis. A conceptual sizing tool was created in MATLAB using equations, assumptions, and rule-of-thumb metrics in an attempt to accomplish this objective. This work was performed through support of the AFRLRQQ Intelligent Power Systems program.
