Development of an Aerospike Nozzle for a High Performance Green Hybrid Propulsion (Hpghp) System for Small Satellites

Development of a Reusable Aerospike Nozzle for Hybrid Rocket Motors

The Department of Mechanical Engineering at the California Polytechnic State University, San Luis Obispo, has developed an innovative program of experimental research and development on hybrid rocket motors (where the fuel and the oxidizer are in different phases prior to combustion). One project currently underway involves the development of aerospike nozzles for such motors. These nozzles, ho...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

SSC04-XI-6 Advancing the Utility of Small Satellites with the Development of a Hybrid Electric-Laser Propulsion (HELP) System

Some of the major space operational capabilities desired for modernizing and transforming our existing space infrastructure include: 1) in-space robotic assembly of modular structures, 2) routine spacecraft repositioning and rescue services, 3) use of formations of satellites that can perform functions not possible with traditional single large structures. All of these applications can make use...
