Long-life piston fuel storage tank adapted to extreme weather conditions

Abstract

The invention provides a long-service-life piston type fuel storage tank adapted to extreme climate conditions. The long-service-life piston type fuel storage tank adapted to extreme climate conditions comprises a storage tank cylinder body, a piston, an air path end cover, a liquid path joint, a sensor magnetic induction seat, an air path three-way pipe and a fuel level sensor, wherein one end of the storage tank cylinder body is provided with the liquid path joint; the other end of the storage tank cylinder body is provided with the air path end cover; one side of the air path end cover is provided with a concave structure; the other side of the air path end cover is provided with a convex structure; the fuel level sensor is arranged on the internal side of the concave structure of the air path end cover; the piston is arranged in the storage tank cylinder body and can slide along the inner wall of the storage tank cylinder body; one side of the piston is provided with a concave structure; the other side of the piston is provided with a convex structure; and the sensor magnetic induction seat is arranged in the concave structure of the piston. According to the invention, problems such as fuel discharging frequency, limited working environment temperature and the like of the storage tank can be preferably solved.

Description

technical field [0001] The invention relates to aerospace vehicle power equipment, in particular to a long-life piston fuel storage tank adapted to extreme weather conditions. Background technique [0002] At present, in the power system of aviation aircraft, the main function of the fuel system is to ensure that the aircraft can continuously and effectively supply fuel to the engine under various ground and flight conditions (including extreme conditions and various maneuvering flight conditions), that is, to meet the requirements of the engine fuel pump. Inlet flow, pressure, temperature, vapor-liquid ratio requirements. Compared with aerospace vehicle tanks, aircraft fuel storage tanks do not require complex liquid management devices, and only rely on the gravity of the earth in the flight environment and the thrust acceleration in the engine to ensure the separation of fuel and gas, so that the vapor-liquid ratio at the inlet of the fuel pump fulfil requirements. In th...
