manufacture of aircraft engines. SUBSTANCE: engine includes lower case with intake device and jet propulsion nozzle. Shaft with compressor and gas turbine mounted on it is located inside lower case. Shaft is mechanically connected with reduction gear which is swivel in front portion of lower case. It is located in intake device housing and is connected with upper reduction gear by means of vertical shaft; it is mounted under lower case and is shifted forward relative to longitudinal axis of lower case. Secured on output shafts of upper reduction gear are disks. Each disk has front smooth polished surface; rear surface of each disk has round or square passages located over concentric circles in even number in each of them. Longitudinal axis of each passage is inclined forming angle with plane running through center of rotation. Bottom of each passage is parallel relative to front and rear surfaces of disk owing to which areas of opposite side walls of each passage are equal in longitudinal and transversal directions. EFFECT: improved operational properties of engine. 2 dwg |
