Intelligent fuel oil supply device for aviation turbine engine

Abstract

The invention discloses an intelligent fuel oil supply device for an aviation turbine engine, which comprises an oil supply ring and a fuel oil nozzle spraying connecting part, and the oil supply ring comprises a main oil supply ring and at least one auxiliary oil supply ring; one end of the fuel nozzle connecting part is connected with the fuel supply ring, the other end of the fuel nozzle connecting part is connected with the fuel nozzle, a main fuel supply channel, an auxiliary fuel supply channel and a nozzle mounting channel are formed in the fuel nozzle connecting part, and the main fuel supply channel and the auxiliary fuel supply channel are both communicated with the nozzle mounting channel; the fuel oil nozzle is installed on an outlet of the nozzle installation channel, an oil inlet of the fuel oil nozzle is communicated with the main oil supply channel and the auxiliary oil supply channel at the same time through the nozzle installation channel, the main oil supply channel is communicated with the main oil supply ring, and the auxiliary oil supply channel is communicated with the auxiliary oil supply ring. According to the invention, the adjustment range of the oil supply amount is expanded, and the oil supply uniformity of the main-stage fuel nozzle in the circumferential direction of the head of the combustion chamber is realized.

Description
