摘要： A process for measuring the wheel profiles of wheels of wheelsets in which the wheelsets are moved past a series of a least twenty-six separate sensors while being rotated and moved at specified speeds. The wheelsets are impinged with a multiplicity of laser beams whose reflections are measured by the sensors, thereby indicating various wheel profile properties. In one embodiment, the wheelsets are rotated at a speed of less than 75 revolutions per minute while being moved at a speed of less than 6 miles per hour. In another embodiment, the wheelsets are rotated at a speed of greater than 400 revolutions per minute while being moved at a speed of greater than 45 miles per hour. In both embodiments, the wheelsets are moved past the sensors in a period of less than about 20 seconds.

摘要： The combustion of a hybrid engine is improved by continuously injecting into a precombustion chamber a hypergolic fluid such as triethyl aluminum which exothermically reacts with and vaporizes the oxidizer such as liquid oxygen. The prevaporized oxidizer evenly combusts the solid propellant grain to develop thrust.

摘要： A system is provided for reducing the emissions of hydrochloric acid (HCl) from solid fuel rockets, especially during ground disposal. An aqueous solution (40, FIG. 2 ) of an alkali metal hydroxide is injected as a mist (50) into the rocket chamber (32) as the rocket fuel (30) is burned. The reaction of the alkali metal with hydrogen chloride (HCl) produces a salt and thereby minimizes the presence of hydrochloric acid in the rocket exhaust. An injected neutralizing material which reduces hydrochloric acid, but which produces less thrust than an equal weight of rocket fuel, can be injected into an operating rocket which carries a payload high above the earth, with the injected material being injected only while the rocket is at a lower altitude when hydrochloric acid is most undesirable. The injected material can be produced by a small auxiliary rocket device (82, FIG. 4 ) whose exhaust (84) is delivered directly to the main rocket chamber (86), and with the exhaust of the auxiliary rocket device including a high proportion of magnesium to react with the hydrochloric acid with minimal degradation of rocket performance.
摘要翻译：提供一种系统，用于减少固体燃料火箭的盐酸（HCl）排放，特别是在地面处置过程中。当火箭燃料（30）燃烧时，碱金属氢氧化物的水溶液（40，图2）以雾（50）的形式被注入到火箭室（32）中。碱金属与氯化氢（HCl）的反应产生盐，从而使火箭尾气中盐酸的存在最小化。注入的中和材料，其减少盐酸，但是产生比同等重量的火箭燃料更少的推力，可以注入到运载火箭中，该火箭携带高于地球的有效载荷，注入的物质仅在火箭处于当盐酸最不希望时，较低的高度。喷射的材料可以通过其排气（84）直接输送到主火箭室（86）的小型辅助火箭装置（82）产生，并且辅助火箭装置的排气包括高比例的镁与盐酸反应，火箭性能降低最小。

摘要： A solid propellant component grain is supported in a combustion chamber. A liquid propellant component container is mounted forward of the combustion chamber. The liquid propellant component is supplied through conduits from the container into the combustion chamber, and ignited to form combustion gas which is discharged out the rear of the combustion chamber to generate thrust for propelling a rocket. A high pressure tank containing a non-flammable gas such as helium is at least partially embedded in the grain. A conduit leads from the tank into the container, such that the high pressure gas pressurizes the container and urges the liquid propellant component to flow from the container into the combustion chamber. The tank provides internal structural support for the grain, with the wall of the combustion chamber constituting a safety barrier in the event of structural failure of the tank after the tank is filled with high pressure gas.

摘要： A liquid-solid propulsion system having a tank of liquid oxygen and a high pressure chamber loaded with solid grain fuel with a portion of the liquid oxygen being passed through a heat exchanger to convert the liquid oxygen to gaseous oxygen. The gaseous oxygen is directed to the chamber or solid grain fuel to induce a fuel rich gas burn that is directed to a thrust chamber which also receives liquid oxygen to increase the characteristic velocity of the exhaust and thereby provide the specific impulse of the propulsion system. The gaseous oxygen is also directed to the liquid oxygen tank to pressurize the flow of liquid oxygen from the tank. Valves are interposed to control the flow of liquid and gaseous oxygen to provide the required mixture ratio in the thrust chamber for optimum specific impulse or to terminate the thrust of the propulsion system. A method for providing the liquid-solid propulsion system is also disclosed.

摘要： A single-chamber rocket motor containing both a hybrid fuel charge (with associated oxidizer) and a solid propellant charge. Termination of the hybrid motor at the time desired provides accurate missile range zoning. The hybrid fuel charge is in tandem with and forward of the solid propellant charge which provides the minimum impulse of the rocket motor and the minimum missile range. The volume vacated by the solid propellant charge serves as a mixing chamber for more efficient hybrid fuel charge combustion. A gas mixer baffle plate separates the two charges and provides additional mixing.

摘要： A fuel unit for a hybrid hot-gas generator comprises two consumable constituent parts of different compositions which are separated by a partition which in storage conditions is stable and chemically inert with respect to said two parts and which is consumable during operation of the generator. Reactions between said constituent parts during storage, which might impair the combustion of the fuel unit, are thereby prevented.
