Turboshaft engine i.e. turbojet, for propelling aircraft, has high pressure shaft comprising distribution openings that distribute oil from space to bearing and extend obliquely relative to radial direction defined by axis of engine

摘要

The engine has low pressure and high pressure shafts (10, 20) mounted coaxially relative to each other and extending according to an axis of the engine. The low pressure shaft comprises a set of distribution openings (11) arranged to distribute lubricating oil from a supply unit to a lubrication space (E). The high pressure shaft comprises another set of distribution openings (21) arranged to distribute the oil from the space towards a guide bearing to lubricate the bearing. The latter openings extend obliquely relative to a radial direction (R) defined by the axis.
