Abstract
The invention discloses a rotatably flexible oil extractor. The rotatably flexible oil extractor comprises a rotating shaft, a flexible oil extraction pipe, an oil inlet pipe and an oil delivery pipe, wherein the two ends of the rotating shaft are connected with an oil outlet and an oil supply opening of an oil tank respectively, an angular contact ball bearing is arranged at the connecting position for enabling the rotating shaft to be capable of rotating into the oil delivery pipe, and oil inlet and delivery channels are formed inside the rotating shaft, and are connected with the oil inlet pipe and the flexible oil extraction pipe respectively. According to the rotatably flexible oil extractor, the oil inlet pipe and the oil delivery pipe are arranged on the same rotating shaft, a flexible oil suction opening is formed in the oil delivery pipe, the flexible oil suction opening and the oil delivery pipe form an included angle of 180 degrees, when the flexible oil suction opening is rotated, an air opening is formed above the liquid level all the time, a phenomenon that pressure air is directly blown into fuel oil to cause the mixing of oil and air when the liquid level is changed can be avoided, and a condition of narrow oil extraction range caused by single rotating direction can be avoided due to the flexible oil suction opening; and besides, the operation is simple and less oil is remained when oil is supplied normally or oil is drained on the ground.
Description
Technical field
The present invention relates to a kind of flexible oil drawer, particularly relate to a kind of rotatable flexible oil drawer.Belong to aircraft fuel delivery field.
Background technique
The requirement of modern Aviation aircraft to maneuvering flight ability improves constantly, typicalness has the pull-out etc. in latter end large angle of fall attacking ability, banked turn ability and flight way, during for preventing maneuvering flight state, fuel supply is interrupted, jeopardize flight safety, oil-fired system generally applies fuel oil supply device under various dissimilar zero and negative G condition.
Inverted flight fuel tank, flexible bag, flexible liquid sucting port etc., be overload-resistant oil supplying device conventional at present, inverted flight fuel tank is applicable to the situation of repeatedly transshipping and occurring, but needs residual fuel more, overload time is short, and has on the aircraft at certain hour interval between twice overload; Flexible bag can realize the physical isolation of air and fuel, overload-resistant effective, but its complex structure, control unit are many, and manufacture cost is high; Flexible liquid sucting port is applicable to transship little situation, and its structure is simple, and cost is low, but unavailable fuel oil is more.In a word, existing zero and minusg oil supplying device, because its inlet port mostly is fixing or rigid construction, at less and fuel feeding weak effect when there is maneuvering flight of fuel oil residue.Therefore, need to provide a kind of new technology to solve the problems referred to above.
Summary of the invention
The technical issues that need to address of the present invention are to provide the effective rotatable flexible oil drawer of a kind of fuel feeding.
The present invention is a kind of rotatable flexible oil drawer, this oil supplying device comprises rotatingshaft, flexibility gets oil pipe, oil inlet pipe and transport pipe, the two ends of described rotatingshaft are connected with oil-feed port with main fuel tank oil outlet respectively, joint is provided with radial thrust bearing, make that rotatingshaft can move into, transport pipe rotates, described rotatingshaft inside is provided with oil-feed and oil transportation channel, and this oil-feed and oil transportation channel are got oil pipe with oil inlet pipe and flexibility respectively and be connected.
Described oil inlet pipe and flexibility get oil pipe in same plane, and described oil inlet pipe and flexibility are got to stagger 180 ° between oil pipe and arranged.
The bottom that described flexibility gets oil pipe is provided with the counterweight be with and flexibly connected.
Described oil inlet pipe and transport pipe adopt seal ring and sealing nut to be connected respectively with between overload oil tank wall.
Oil inlet pipe of the present invention and transport pipe are positioned on same running shaft, transport pipe is with flexible inlet port, angle is 180 ° between the two, can ensure that ventilating hole is positioned at more than liquid level all the time during rotation, avoid during level change, occurring that pressure air directly blows into the situation that fuel oil causes air-fuel mixture, flexible inlet port can overcome can only by single direction rotate bring get the narrower situation of oily scope, and time draining the oil in normal fuel injection or ground, simple to operate, excess oil amount is few.

Embodiment
Be further elaborated below in conjunction with embodiment and accompanying drawing.Embodiments of the invention, only for illustration of the present invention, are not used for limiting the scope of the invention.
With reference to figure 1, the rotatable flexible oil drawer of one of the present invention, this oil supplying device comprises rotatingshaft 3, flexibility gets oil pipe 4, oil inlet pipe 7 and transport pipe 6, the two ends of rotatingshaft 3 are connected with oil-feed port 1 with main fuel tank oil outlet 9 respectively, joint is provided with radial thrust bearing 10, and end face end cap 12 is compressed into, such that rotatingshaft 3 can move into, transport pipe 7,6 rotates, rotatingshaft 3 inside is provided with oil-feed and oil transportation channel, and oil-feed and oil transportation channel are got oil pipe 4 with oil inlet pipe 7 and flexibility respectively and be connected.
Above-mentioned oil inlet pipe 7 and flexibility get oil pipe 4 in same plane, and oil inlet pipe 7 and flexibility are got to stagger 180 ° between oil pipe 4 and arranged.
The counterweight 11 that the bottom mounting strap getting oil pipe 4 in flexibility flexibly connects, for controlling center of gravity, driving rotatingshaft 3 to follow overload change and rotating.The section of flexibly connecting can adopt rubber hose with metalwork curing tube or adopt metal bellow to be connected with metal catheter.
In order to ensure sealing, oil inlet pipe 7 and transport pipe 6 adopt seal ring 2 and sealing nut 8 to be connected respectively with between overload fuel tank 5 wall.
Referring to figs. 2 and 3, fuel oil or pressurization gas in main fuel tank, by oil inlet pipe 7(fuel oil or gas inlet manifold) enter overload fuel tank 5, during normal flight, the flexible oil drawer in device vertically downward, is immersed in fuel oil; When having overload to occur, flexible oil drawer can rock together along with fuel oil, flexible oil drawer can slightly movement in the plane vertical with plane of rotation, rotation body structure can not be limited in when overload fuel tank 5 is designed, the restriction of overload fuel tank 5 is reduced, flexible oil drawer is immersed in fuel oil all the time always, and suction port, all the time more than liquid level, ensures that the fuel feeding under maneuvering flight state is uninterrupted continuously.
The oil inlet pipe 7(fuel oil of oil supplying device of the present invention or gas inlet manifold) and transport pipe 6 be positioned on same running shaft, transport pipe 6 is with flexible inlet port, angle is 180 ° between the two, can ensure that ventilating hole is positioned at more than liquid level all the time during rotation, avoid during level change, occurring that pressure air directly blows into the situation that fuel oil causes air-fuel mixture, flexible inlet port can overcome can only by single direction rotate bring get the narrower situation of oily scope, and normal fuel injection or ground are when draining the oil, simple to operate, excess oil amount is few.
According to the overload requirement in the total technical index of aircraft, be converted into pasta angle situation of change, the rate of change according to pasta angle designs rotational velocity, and chooses suitable bearing; Amount of fuel required when calculating overload according to the time of maneuvering flight.
The present invention has the feature of low cost, and has used modular design.Therefore, can be used for using the low cost aircraft of liquid fuel, to meet its less and fuel feeding requirement carried out in maneuvering flight situation at surplus oil.
