Nacelle structure type lubricating oil tank

Abstract

The invention provides a nacelle structure lubricating oil tank. The lubricating oil tank comprises a shell, an oil filling port, an oil supply pipe, a feathering oil supply pipe, a discharging valve,a discharging pipe, a communicating pipe, a breather pipe and a rear wall plate. The shell comprises a rear wall plate, a front wall plate, an inner skin, an outer skin and at least two sealing partitions. The at least two sealing partitions are arranged in an annular cavity enclosed by the rear wall plate, the front wall plate, the inner skin and the outer skin. At least two support partitions are arranged between the outer skin and the inner skin. The oil filling port is formed in the upper portion of the outer skin. The two sealing partitions below the outer skin are connected through thecommunicating pipe. The feathering oil supply pipe and the discharging pipe are arranged on the communicating pipe. The feathering oil supply pipe is connected with the aircraft feathering oil supplypipeline. The discharging pipe is located at the bottom of the communicating pipe. The discharging valve is arranged at the bottom of the discharging pipe. The oil supply pipe is arranged in the middle of the rear wall plate. The breather pipe is communicated with the left side and the right side of the lubricating oil tank.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and relates to a nacelle structure lubricating oil tank, in particular, the functions of refueling, oil storage, oil supply and oil discharge can be realized by utilizing the space of the nacelle structure. Background technique [0002] The oil tank on the aircraft is generally provided by the engine, or a separate integrated fuel tank is set in the engine nacelle. The fuel tank is generally made of castings or welded parts, and has nothing to do with the structure of the engine nacelle, which has a large weight and space. The problem of waste, and the lubricating oil tank may face the problem of rotor containment, so the layout is difficult. Contents of the invention [0003] The invention provides a lubricating oil tank with a nacelle structure, which has the functions of refueling, oil storage, oil supply and oil discharge, can rationally utilize the space of the nacelle, and store l...
