摘要： An active balancing system for rotating machinery is provided which is light weight, solid state and powered by radiant energy. One or more balance rings coupled to the rotating machinery each have balancing elements which are moved to a selected position by actuators whose operation is controlled according to measured vibration resulting from imbalance of the machinery. The actuators are powered by an electrical energy generating device, such as a photo cell or a photovoltaic element, which is coupled to the machinery and located across an air gap from a source of radiant energy such as an array of light emitting diodes.

摘要： A ram air turbine comprises a turbine housing which mounts a number of circumferentially spaced turbine blades that function predominantly as impulse turbine blades and a number of splitters, each located in between adjacent turbine blades, which function predominantly as a reaction turbine blade but are shorter in length than the turbine blades. The cross section of the turbine housing decreases between its forward and aft ends while the height of both the turbine blades and splitters increases in the same direction such that the tips of the turbine blades and splitters collectively form a substantially cylindrical shape.

摘要： A seal comprises the combination of a primary seal and a secondary seal each of which acts on at least one shoe that is installed with clearance relative to one of a rotor and a stator in a position to create a non-contact seal therewith. The at least one shoe is provided with a surface geometry and labyrinth-type teeth that influence the inertia of fluid flowing across the seal, and, hence, the velocity of the fluid and the pressure distribution across the seal, ultimately affecting the balance of forces applied to the seal.

摘要： A brush seal for sealing a circumferential gap between two relatively rotating machine components, e.g. the rotor or shaft and stator of a fluid flow machine, such as a gas turbine engine. One end of a plurality of seal bristles is fixed in an annular shape and are mounted to the stator, and their opposite ends are attached to a number of individual shoes located at the rotor. The shoes function very similarly to that of a tilting pad bearing shoe. Prior to shaft rotation, the shoes are in contact with the rotor surface with preferably the leading edge of each shoe set to have less contact than the trailing edge of the shoe. As such, when the rotor begins to rotate, a hydrodynamic wedge is created which lifts the shoe slightly off the surface of the shaft allowing the shoe to effectively “float” over the shaft at a design gap.
