摘要:
A Projectile Continuous Power Module (PCMP) is configured to take incoming or oncoming airflow of an inflight projectile and direct the airflow to a turbine for converting the airflow into electrical power. The PCMP is mounted within or otherwise coupled to an airframe of the projectile. The PCMP is coupled to the projectile in a manner such that an air inlet of the projectile is positioned to capture incoming or oncoming boundary layer airflow as the projectile travels.

A method of balancing turbocharger rotating assembly (50) includes installing a shaft-and-turbine wheel subassembly (40) into a ball bearing cartridge (20) within a bearing housing (8) of a turbocharger (1), connecting a compressor wheel (5) to the shaft (6), and testing the balance of the turbocharger rotating assembly (50) while the turbocharger rotating assembly (50) is installed within the bearing housing (8) of the turbocharger (1). Based on the results of the balance testing, material is removed from the turbine wheel (4) while the shaft-and-turbine wheel subassembly (40) is installed within the bearing housing (8) of the turbocharger (1). The step of removing the material from the turbine wheel (4) comprises removing material from a peripheral edge (35) of a backwall (34) of the turbine wheel (4).
摘要:
The present invention relates to a turbocompound unit (100), comprising a bearing housing (110) and a turbine shaft (120) being rotatably supported in the bearing housing (110), wherein one end of the turbine shaft (120) is provided with a turbine wheel (122). The turbocompound unit (100) further comprises a diffuser duct (130) in which the turbine wheel (122) is arranged to rotate, an exhaust collector (140) extending from the diffuser duct (130) to an exhaust outlet (142), and a sealing arrangement (150) positioned in the vicinity of the turbine wheel (122) for preventing oil from escaping from the bearing housing (110) to the diffuser duct (130). The turbocompound unit is characterized in that the exhaust collector (140) forms part of a buffer gas duct (160) that is arranged to supply exhaust gas from the exhaust collector (140) to the sealing arrangement (150) for pressurizing the sealing arrangement (150).
