摘要: A hydrocarbon leak detection sensor having a hydrocarbon indicator paint applied to a surface exposed to a flow in which the presence of a hydrocarbon is detected. The sensor is located at a low point in a static drain line that is connected to a main fuel line of a liquid propellant rocket engine between a main fuel valve and a fuel injector of a combustion chamber. The sensor includes a housing with a flow inlet port and a flow outlet port with an optical device opposed to a removable plug that secures a target disk with a hydrocarbon indicator paint applied to an exposed surface. A light source is used to illuminate the hydrocarbon indicator that changes color from white to red in the presence of a hydrocarbon.

摘要: A turbopump for a liquid rocket engine in which an oxidizer is pumped, where the turbopump is formed with a single piece rotor within a single piece housing by a metal additive manufacturing process, and where surfaces exposed to the oxidizer is coated with enamel glass to provide a smooth surface over the rough printed surface and to provide burn resistance to the base metal from exposure to the oxidizer such as oxygen. A Mondaloy coating can be used below the enamel glass coating to add additional burn resistance to the base metal.

摘要: An extendable nozzle for a rocket engine includes a chamber with a main combustion chamber and a throat and a main nozzle formed within a guide tube, where a nozzle extension slides over the guide tube from a stowed position to an extendable position. A locking O-ring secures the nozzle extension in a stowed position, and a locking split ring holds the nozzle extension in the extended position.

摘要: A Helmholtz resonator is used to detect a presence of a two-phase flow in a conduit. The resonator is sized so that a range of frequencies it is tuned for corresponds to a change in the speed of sound as the fluid changes from all liquid, to liquid plus vapor, and to all vapor. A band-pass filter is used to cancel out any external noise that would pollute the signal from the resonator. The resonator is used to monitor for a two-phase flow occurring within a feed line leading into a turbopump of a rocket engine.

摘要: In a gas turbine engine having a rim cavity formed between a rotor disk and a stator, and a brush seal or other seal member providing an airflow seal between the stator and a side plate of the rotor disk, a thermally responsive valve device is located in the bypass passage of the stator to form a parallel air flow path with the brush seal. As the brush seal wears and the leakage airflow around the worn brush seal increases, the air flow temperature in the rim cavity would decrease. The thermally responsive valve device would detect the decreasing airflow temperature, and reduce the airflow passing through the bypass passage in order to prevent the temperature of the rim cavity from decreasing. The temperature responsive valve device makes use of a bimetallic valve member that regulates airflow based upon temperature.

摘要: A bearing lubrication system for a high temperature bearing, such as in a small gas turbine engine for a UAV, in which the bearing and lubricant requires a long shelf life, where the bearing includes a solid lubricant movable within a chamber formed within a housing and located adjacent to the bearing. The solid lubricant is biased by a spring toward the bearing and abuts against a runner that rotates along with the rotor shaft during engine operation. A cooling air passage opens into a space formed between the bearing and the solid lubricant to supply cooling air through the bearing. When the engine operates, heat is transferred through the runner to the solid lubricant to melt the lubricant. Rubbing of the runner against the biased solid lubricant will also melt the lubricant. The melting lubricant is carried by the cooling air through the bearing to provide both cooling and lubrication for the bearing.

摘要: A turbine disc used in a turbo-pump that is exposed to a large thermal gradient across the sides of the rotor disc. The warm side of the turbine disc is covered by a cover plate that forms a sealed space between the turbine disc and the cover plate, and this space is evacuated or insulated to form a complete vacuum or as near as a complete vacuum as possible. The surfaces of the turbine disc and cover plate that form the vacuum space are also coated with a reflective coating such as with a highly polished surface of low emissivity in order to minimize the radiation heat loss through the vacuum space. The turbine disc can have a cover plate forming a vacuum space or insulated cavity on both sides of the turbine disc. Ribs are also used within the vacuum space as supports for the cover plate due to the difference in pressure from the ambient side and the vacuum.
