The invention discloses a lubricating oil supply system based on a gas turbine engine and the gas turbine engine. The lubricating oil supply system comprises a lubricating oil supply pipe and a lubricating oil collecting device. A pipe connector at one end of the lubricating oil supply pipe is used for being connected with a lubricating oil supply way, and a pipe connector at the other end of the lubricating oil supply pipe is used for being connected with a rear bearing connecting guide pipe connector of a gas generator rear bearing of the gas turbine engine so as to provide lubricating oil for the gas generator rear bearing. The lubricating oil collecting device is wrapped on the outer surface of the connecting part of the rear bearing connecting guide pipe connector and the lubricating oil supply pipe and is used for collecting the lubricating oil leaking at the connecting position of the rear bearing connecting guide pipe connector and the lubricating oil supply pipe, the collected leaking lubricating oil is guided out of a high-temperature part of the gas turbine engine, and therefore the risk that the lubricating oil leaks to the high-temperature part, and a fire is caused is effectively avoided. By means of the lubricating oil supply system based on the gas turbine engine and the gas turbine engine, the lubricating oil supply safety is good, and reliability of a lubricating oil pipeline is high.
Description
technical field [0001] The invention relates to the field of gas turbine engines, in particular to a lubricating oil supply system based on a gas turbine engine. In addition, the present invention also relates to a gas turbine engine comprising the above-mentioned lubricating oil supply system based on the gas turbine engine. Background technique [0002] The gas turbine engine sends lubricating oil to the rear bearing of the gas generator through a lubricating oil supply pipe to lubricate and cool the rear bearing of the gas generator. Both ends of the lubricating oil supply pipe are connected in the form of pipe joints, and the oil outlet pipe joints are generally installed on high-temperature parts such as turbines or combustion chamber casings. When the gas turbine engine works abnormally and vibrates abnormally, the oil supply pipe may crack or even rupture near the joint, causing the oil to leak on high-temperature components such as the turbine case, which may cause ...
