The air refueling technology is a technology for replenishing fuel oil to other oil-receiving airplanes by a refueling machine in flight, so that the cruising ability of a military airplane can be obviously improved, the dependence of the military airplane on an airport is reduced, the dispatching space of the airport is increased, and the like. The air refueling technology has an extremely important supporting role for air force troops in battle in strategic or tactical aspects.
At present, the mature aerial refueling modes in the world mainly comprise two modes, wherein one mode is hose type aerial refueling equipment and is also called a hose-floating anchor type refueling system; another type is flying truss type telescopic truss type aerial refueling equipment, also called hard refueling equipment. The operation of modern airborne fueling techniques is a complex process, with the fueling sequence typically having four stages, convergence-docking-fueling-disengagement.
Although the last hundred years have passed since the advent of airborne fueling, the basic principles of airborne fueling have not changed, whether hose fueling or hard-hose fueling, which still requires equipment to connect the fuel tank and the fuel rail, and in practice, presents a number of problems, such as:
1) the air refueling needs a high flying technology and extremely delicate coordination, and during refueling, the refuelling machine and the refueling machine have no defense capability and are extremely easy to be stolen by enemy aircraft and need to be protected by other military aircrafts;
2) one hard tube type oiling machine can only refuel one military aircraft, and other aircraft can only wait, so that the refueling efficiency is low, and the time consumption is long;
3) the hose and other equipment of the oiling machine are also professional equipment, so that the maintenance cost is higher; in addition, the refueling hose is sensitive to atmospheric turbulence, so that the docking is difficult, and the technical requirement on a driver is high; secondly, the hose oil conveying speed is slow, about 1500 liters per minute, and the time for refueling a large airplane is long;
4) rigid connection is adopted in hard tube type oiling, no buffer exists when the hard tube type oiling machine is subjected to other forces, the hard tube type oiling machine can only be hard to touch, and as a result, the damage of a connection part is easy to cause;
5) the existing hard tube type air refueling is characterized in that two flying airplanes are connected through an oil delivery pipe for oil delivery, a rigid oil pipe is connected between the two moving airplanes, if the two flying airplanes are subjected to the acting force of air flow, the oil delivery pipe cannot be deformed, and only can be blown by wind, the high-altitude air flow is turbulent, the connection strength is greatly tested, and in addition, the two flying airplanes are in motion, and the relative speed of the two flying airplanes is difficult to control;
6) during docking, the hard tube type air refueling needs an operator on the refueling machine to operate a fine oil delivery pipe to extend to a small oil receiving hole above the oil receiving machine which is several meters away, which is undoubtedly a very challenging work and has the risks of docking failure, damage to the body and easy accident triggering.

A use method of an air-to-air refueling system of an air military aircraft comprises the following steps:
and S1, manufacturing the spherical oil bullet 3.
And S2, loading, specifically, after the fuel dispenser 1 receives an instruction that a military aircraft needs to carry out air refueling in the air, the fuel dispenser 1 enters a loading working procedure. In order to reduce the convergence time of the oiling machine 1 and the oil receiving machine 2, the oiling machine 1 needs to be provided with the spherical oil bombs 3 in advance, taking the number of the telescopic joints as three as an example, at this time, the adjusting oil cylinder 12 at the tail part of the body of the oiling machine 1 presses the first telescopic joint out of the body to be in a tail inclined state, then under the driving of the electric winch 16, the second telescopic joint and the third telescopic joint are pushed out outwards through a winch steel wire 17 fixed on a steel wire fixing pin 18, and when the second telescopic joint and the third telescopic joint are pushed to be in a completely extended state, the electric winch 16 stops working; and then the sealing cover 14 is opened in the body of the oiling machine 1 according to the direction of an arc arrow in the figure 1, the spherical oil bomb 3 is filled into the three-section expansion joint, the surface layer of the spherical oil bomb 3 is made of elastic materials with good air tightness, and the inside of the spherical oil bomb is filled with the aviation fuel.

In addition, the fuel dispenser 1 can eject the amount of spherical fuel balls 3 required to be filled by the fuel receiver 2 according to the instruction of the fuel receiver 2. The spherical oil bomb 3 in the ejection tube 11 can be ejected by a single spherical oil bomb 3 or by a plurality of spherical oil bombs 3 continuously according to the requirement of the refueling amount, and the ejection speed is controlled by the pressure of the air pressure provided by the pressurizing air nozzle 15. After the oil receiving machine 2 adds the required number of the spherical oil bullets 3, the oil receiving hatch cover 22 is closed, and the outer skin of the spherical oil bullets 3 after the oil is added can be recycled, so that the oiling working procedures of the two machines are finished.
