Jet drive i.e. gas turbine, for airplane, has thrust nozzle with two parts, where one of parts has cylindrical outer part and inner part tapering in flow direction of turbine shaft, and another part has outer part tapering in flow direction

摘要

The drive has a compressor (1), a combustion chamber (2), and a thrust nozzle (5) consisting two parts, where one of the parts has a cylindrical outer part and an inner part tapering in a flow direction of a turbine shaft (4). Another part has an outer part tapering in the flow direction. A turbine assembly (3) has turbine stages (6, 7), where the latter part of the nozzle is designed as a diffuser. The turbine stages generate torque for aligning flow between blades, where acceleration of gases in the latter part takes place during expansion of the nozzle.
