There is a growing interest in the use of micro and nanosatellites within the aerospace community. Constellations of small satellites may eventually replace much larger, single function spacecraft as a cheaper, more flexible alternative. Micro-technologies will be required to enable small satellite missions including efficient, low-cost propulsion systems for maneuvering. A MEMS fabricated prop...

Over the last century chemical propellants have been the dominant fuel source for the aviation and aerospace industry, primarily because they are able to provide ample power for a limited cost. However, over the last decade as the price of chemical propellant continues to soar and their detrimental effect on our environment comes to light, there has been a surge to develop an alternative propul...

Originating from the early 1920's, the so-called Biefeld-Brown effect claims the generation of thrust in capacitor configurations exposed to high voltage. This thrust was claimed to be not due to corona wind phenomena and also exists in vacuum. These claims, although only published in patents, survived until recent publications for very advanced propulsion concepts. This paper reviews Brown's a...

A numerical framework for studying plasma flows in electric propulsion systems is developed. The novelty of this kinetic-theory-based method is the spectral treatment of the Boltzmann collision operator using Fourier-Galerkin scheme coupled with the computational efficiency of the streaming of the lattice Boltzmann method. This spectral treatment (i) avoids the low Mach number restriction of th...

In this study, three-dimensional simulations of xenon plasma plume flow fields from a cluster of four Hall thrusters are performed with a hybrid particle-fluid method on unstructured meshes. In these simulations, a detailed fluid model is used to compute the electron properties, the direct simulation Monte Carlo method models the collisions of heavy particles and the Particle-In-Cell method mod...

Acrylonitrilebutadiene-styrene (ABS) thermoplastic is evaluated as a potential fuel for hybrid rocket motors and compared to the widely used fuel material Hydroxyl-Terminated Polybutadiene (HTPB). For this project Nitrous Oxide (N2O) is used as the matching oxidizer. ABS is widely mass-produced for non-combustion applications including household plumbing and structural materials. Analytical pre...

in this work, the feasibility study for design of a laboratory sample rde which has an annular geometry with diameter of 76 mm and length of 101 mm has been performed. detonation engines are expected to be used as propulsion system in aerospace applications in the future. several types of detonation engines are currently under examination, including the rotating detonation engine (rde). first, ...
