Abstract
The utility model relates to a biaxial rotating type oil absorption ventilation device for aerobatics, and belongs to the field of aviation machinery. The biaxial rotating type oil absorption ventilation device for aerobatics comprises an oil supply assembly, a ventilation assembly and a rotating shaft; the rotating shaft is a hollow body, the two ends of the rotating shaft are cylinders, and a hole is formed in the side wall of each cylinder; the oil supply assembly is communicated with a lubricating oil outlet of a lubricating oil tank, and is connected to one end of the rotating shaft in a sleeved mode; the ventilation assembly is communicated with a ventilation hole of the lubricating oil tank, and is connected to the other end of the rotating shaft in a sleeved mode; the port of each cylinder of the rotating shaft is connected with a plug cap, and the plug caps are fixed through a cone end fastening screw. The biaxial rotating type oil absorption ventilation device for aerobatics has the advantages that the aims of continuously supplying the lubricating oil to an engine under a continuous negative overload state and meeting the ventilation requirement of the lubricating oil tank are effectively achieved, and the device is simple in structure, light in weight and good in system stability.
Description
Technical field
The utility model relates to the oil suction air-breather that a kind of aircraft uses in aerobatics process, belongs to aviation machine field.
Background technique
Aircraft, in aerobatics process, there will be minusg or the flight of inverted flight state of certain time, and the flight of this state is particularly common on sports type, trainer version and military aircraft.Under this regime of flight, system should be able to guarantee that lubricating oil transports to motor continuously reliably.Change due to aspect, lubricating oil in oil tank can depart from fuel tank bottom, flow to oil tank top, and oil tank is positioned at oil tank bottom to the outlet of motor lubrication delivery, the ventilating hole of oil system is positioned at the top of oil tank, if do not taked key measure cannot guarantee to the ventilation requirement of the continual and steady lubrication delivery of motor and oil system.But aircraft is continuing to guarantee that oil system is the technical barrier of aircraft system design to the continual and steady fuel feeding of motor under negative G condition.
Summary of the invention
The purpose of this utility model is to solve the problems of the prior art, and a kind of simple in structure, lightweight and Double-shaft rotary aerobatics oil suction air-breather that the stability of a system is good is provided.
For achieving the above object, the utility model adopts following technological scheme: a kind of Double-shaft rotary aerobatics oil suction air-breather, and described Double-shaft rotary aerobatics oil suction air-breather comprises fuel feeding assembly, ventilation assembly, rotating shaft; Described rotating shaft is hollow body, and its two ends are cylindrical body, and on cylindrical sidewall, arrange porose; Described fuel feeding assembly is communicated with the outlet of oil tank lubricating oil, is socketed on one end of rotating shaft; Described ventilation assembly is communicated with oil tank vent, is socketed on the other end of rotating shaft; The cylindrical body port of described rotating shaft is connected with blocking cap, and holds Cock screw to fix by cone.
Working principle: when aircraft carries out inverted flight aerobatics, flow of oil in oil tank is to oil tank top, fuel feeding assembly in this device is under counterweight effect, inverted flight with aircraft went to oil tank top by being originally placed in oil tank bottom, the inlet port that is used for the pipe of oil suction also goes to oil tank top thereupon, guarantees that oil system can continue continuously reliably to motor lubrication delivery; The ventilation assembly of this device is transferred to the position of ventilating hole the bottom of oil tank by the effect of counterweight by the top of original oil tank.Now oil tank bottom lubricating oil flows to oil tank top entirely, and remaining space is air entirely, has guaranteed the ventilation demand of oil system.The counterweight of the fuel feeding assembly of Double-shaft rotary aerobatics oil suction air-breather and ventilation assembly is decided by aircraft overload, this with regard to having guaranteed inlet port and being always immersed in oil and ventilating hole always above pasta.Under any overload, (comprise negative G condition) and all can be drawn onto oil and keep ventilation, guarantee to motor non-interruptible supply lubricating oil.
Compared with prior art, tool has the following advantages the utility model: efficiently solve the problem continuing under negative G condition to motor non-interruptible supply lubricating oil and oil tank self ventilation requirement, and simple in structure, lightweight, the stability of a system is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described in further detail: a kind of Double-shaft rotary aerobatics oil suction air-breather, described Double-shaft rotary aerobatics oil suction air-breather comprises fuel feeding assembly 1, ventilation assembly 2, rotating shaft 4; Described rotating shaft 4 is hollow body, and its two ends are cylindrical body, and on cylindrical sidewall, arrange porose; Described fuel feeding assembly 1 is communicated with the outlet of oil tank lubricating oil, is socketed on one end of rotating shaft 4; Described ventilation assembly 2 is communicated with oil tank vent, is socketed on the other end of rotating shaft 4; The cylindrical body port of described rotating shaft 4 is connected with blocking cap 3, and holds Cock screw 5 fixing by cone.
Working principle: when aircraft carries out inverted flight aerobatics, flow of oil in oil tank is to oil tank top, fuel feeding assembly in this device is under counterweight effect, inverted flight with aircraft went to oil tank top by being originally placed in oil tank bottom, the inlet port that is used for the pipe of oil suction also goes to oil tank top thereupon, guarantees that oil system can continue continuously reliably to motor lubrication delivery; The ventilation assembly of this device is transferred to the position of ventilating hole the bottom of oil tank by the effect of counterweight by the top of original oil tank.Now oil tank bottom lubricating oil flows to oil tank top entirely, and remaining space is air entirely, has guaranteed the ventilation demand of oil system.The counterweight of the fuel feeding assembly of Double-shaft rotary aerobatics oil suction air-breather and ventilation assembly is decided by aircraft overload, this with regard to having guaranteed inlet port and being always immersed in oil and ventilating hole always above pasta.Under any overload, (comprise negative G condition) and all can be drawn onto oil and keep ventilation, guarantee to motor non-interruptible supply lubricating oil.
The utility model is simple in structure, if to primary clustering of the present utility model, (fuel feeding assembly, ventilation assembly, rotating shaft) makes the change of shape, size and counterweight, still belongs to protection domain of the present utility model.
