Title: David H Edmonds: Innovator in Auxiliary Power Units
Introduction
David H Edmonds is a notable inventor based in Tempe, AZ (US). He has made significant contributions to the field of auxiliary power units (APUs), holding a total of 4 patents. His innovative designs focus on improving efficiency and reducing emissions in power generation systems.
Latest Patents
One of his latest patents is for an integrated gearless and nonlubricated auxiliary power unit. This APU features a compressor, a turbine, a combustor, and a starter-generator unit all integrated within a single containment housing. The turbine has an output shaft on which the compressor is mounted, and the starter-generator unit is coupled to the turbine output shaft without any intervening gears. The rotating components are supported within the containment housing using bearings that do not require a flow of lubricating fluid. Another significant patent is for an auxiliary power unit that includes a rotary fuel slinger. This design features a single-spool, two-stage turbine, where the rotary fuel slinger receives a rotational drive force from the turbine and a supply of fuel from a fuel source. The rotary fuel slinger injects the fuel into a combustor as a continuous 'fuel sheet,' improving fuel mixing and atomization, which reduces emissions and enhances turbine life.
