摘要： A method and system improving energy efficiency of a turbojet engine by optimizing rotating speed of a fan and operability of an engine, by freeing the fan from exclusive control of a low-pressure (LP) shaft by providing combined control with a high-pressure (HP) shaft when cruising power has been reached. The turbojet engine include at least one LP turbine and one HP turbine coupled to coaxial LP shafts and HP shafts, respectively, which can drive LP and HP compressors, respectively. The LP compressors include a fan that forms a first primary air-intake compression stage. The LP and HP shafts are mounted on one of two driving mechanisms, an inner ring gear, and a planet carrier for a planetary gear train for driving the fan, the HP shaft being mounted on a disengagement mechanism and the fan being coupled to the planetary gear train via an outer driven ring gear.

摘要： A brake assembly (44) for an air turbine starter (10) includes a brake cylinder (46) located in the air turbine starter (10). A brake piston (48) is located at least partially within the brake cylinder (46) and slidable therein. A biasing member (50) biases the brake piston (48) toward a turbine wheel (12) of the air turbine starter (10) applying a braking force to the turbine wheel (12) and defining a piston chamber (58) between the turbine wheel (12) and the brake piston (48). A through opening (56) in the brake piston (48) into the piston chamber (58) is configured such that a flow of fluid through the through opening (56) into the piston chamber (58) applies a force to the brake piston (48) sufficient to overcome the bias thereby allowing rotation of the turbine wheel (12).

摘要： An axial flow turbine motor is provided which includes a rotor with a peripheral row of drive blades and a peripheral band-shaped wall element radially clamped against the tops of the drive blades, and a housing with at least one pressure medium inlet nozzle and an annular inner surface surrounding the rotor drive blades and the wall element, wherein the wall element is arranged to withstand centrifugal forces and uphold its clamping engagement with the drive blades at rotor speed levels up to a predetermined speed level, but to expand and loosen its clamping engagement with the drive blades at speed levels above the predetermined speed level, thereby moving into contact with the annular surface and interfering with the rotational movement of the rotor so as to prevent the rotor from reaching hazardous high speed levels.

摘要： A synchronizing stationary clutch system for compression braking in a two spool gas turbine engine is provided by the present invention. The synchronizing stationary clutch system allows the two shafts of a two spool gas turbine engine to be reliably coupled at any given speed of either shaft. This coupling ability is useful to a gas turbine engine functioning in a land vehicle for the purpose of slowing the forward momentum of a rolling vehicle. The clutch system may also allow the use of auxiliary power from an electrical motor to start the engine.
