Pulse Detonation Propulsion
The objective of theoretical, computational and experimental studies outlined in this lecture note was to evaluate the design principles and propulsion performance of prospective air-breathing engines operating on pulse detonations of realistic hydrocarbon fuels with a realistic technique of detonation initiation via deflagration-to-detonation transition (DDT). 1.0 INTRODUCTION Activities in th...
متن کاملNuclear Naval Propulsion
The largest experience in operating nuclear power plants has been in nuclear naval propulsion, particularly aircraft carriers and submarines. This accumulated experience may become the basis of a proposed new generation of compact-sized nuclear power plants designs. The mission for nuclear powered submarines is being redefined in terms of signal intelligence gathering and special operations. Th...
متن کاملPulse-Based Polarity Randomization for Ultra Wideband Impulse Radio Systems
Time Hopping (TH) is commonly used for Ultra Wideband Impulse Radio (UWB-IR) systems as a multiple access scheme. Such system suffers from the existence of spectral lines, which in turn require a power back-off of the total signal. Recently, Pulse-based polarity randomization for UWB IR system was proposed. The use of polarity codes can provide additional robustness against the Multiple Access ...
متن کاملImpulse radio pulse shaping for ultra-wide bandwidth (UWB) systems
In this paper, we investigate the design of pulse shaping FIR filters for impulse radio ultrawideband (UWB) communications systems. The goal of the shaping is to meet an arbitrary spectrum mask, e.g., the mask mandated by the FCC for UWB emissions. Compared with classical FIR filter designs, the current problem introduces three new challenges: (1) it is minimax with quadratic constraints, (2) a...
متن کاملCycle Trades for Nuclear Thermal Rocket Propulsion Systems
Nuclear fission has been used as a reliable source for utility power in the United States for decades. Even in the 1940’s, long before the United States had a viable space program, the theoretical benefits of nuclear power as applied to space travel were being explored [Humble, et. al.]. These benefits include long-life operation and high performance, particularly in the form of vehicle power d...
