摘要： Passive reactivity control technologies that enable reactivity control of a nuclear thermal propulsion (NTP) system with little to no active mechanical movement of circumferential control drums. By minimizing or eliminating the need for mechanical movement of the circumferential control drums during an NTP burn, the reactivity control technologies simplify controlling an NTP reactor and increase the overall performance of the NTP system. The reactivity control technologies mitigate and counteract the effects of xenon, the dominant fission product contributing to reactivity transients. Examples of reactivity control technologies include, employing burnable neutron poisons, tuning hydrogen pressure, adjusting wait time between burn cycles or merging burn cycles, and enhancement of temperature feedback mechanisms. The reactivity control technologies are applicable to low-enriched uranium NTP systems, including graphite composite fueled and tungsten ceramic and metal matrix (CERMET), or any moderated NTP system, such as highly-enriched uranium graphite composite NTP systems.

摘要： The present subject matter overcomes the deficiencies in the prior art by introducing or generating charged particles in an air stream and manipulating the air stream with magnetic fields operating on the charged particles. Embodiments of the present subject mater compress the air stream by accelerating charged particles with a moving magnetic field, where the magnetic field has a velocity perpendicular to its flux lines. The increased velocity of the charged particles increases the statistical mean particle velocity and thereby increases the pressure in the air stream. The compressed air stream is then heated and expanded through a second magnetic field. The expansion of the air stream substantially increases the velocity of the air stream and the charged particles therein. The interaction of the high velocity charged particles and the magnetic field imparts a force perpendicular to the flux lines, this force powers the movement of the magnetic field.

摘要： A thruster system is provided for a vehicle that can be used to reduce the roll propensity of a motor vehicle. The system utilizes a control system and multiple sets of thrusters which are strategically placed upon the vehicle. The control system is provided for detecting a potential roll condition and activates selected ones of the thrusters to produce a necessary thrust force for counteracting roll forces. The thrusters are connected to an on-board pressurized gas source that generates the anti-roll thrust force.

摘要： In an underwater vehicle, hydrogen and oxygen are fed into a combustion chamber of a combustor of the underwater vehicle to initiate a combustion reaction, which generates high-pressure steam. The high-pressure steam can be cooled with the injection of seawater, and can be condensed into high-pressure water by the addition of sufficient seawater. High-pressure water is then ejected out of the combustor, generating thrust for the underwater vehicle. Sensors that measure the combustor pressure and the external pressure could be used to adjust the combustor pressure, allowing for constant velocity as the depth of the underwater vehicle changes. Alternatively, the sensors could adjust the area of an exit nozzle of the combustor. Stored water can be converted back into hydrogen and oxygen by using electrical power external to the system. After regeneration of the water into hydrogen and oxygen, the propulsion system would be ready for operation again.
摘要翻译：在水下航行器中，氢气和氧气被输入到水下航行器的燃烧室的燃烧室中以引发产生高压蒸汽的燃烧反应。高压蒸汽可以通过注入海水进行冷却，并通过加入足够的海水将其冷凝成高压水。然后将高压水从燃烧器中排出，产生用于水下航行器的推力。可以使用测量燃烧器压力和外部压力的传感器来调节燃烧室压力，从而随着水下航行器的深度改变而允许恒定的速度。或者，传感器可以调节燃烧器的出口喷嘴的面积。储存的水可以通过使用系统外部的电力转换回氢和氧。在将水再生成氢气和氧气后，推进系统将准备再次运行。
