technical field

The invention relates to the technical field of aerial refueling, more specifically, it relates to an aerial refueling drogue stabilization ring.

Background technique

The application of aerial refueling technology has increased the range of the aircraft, and significantly improved the survivability of the fighter, increasing the efficiency and other aspects of the capabilities have been significantly improved, making the mission impossible to complete possible. In addition, aerial refueling technology subverts the traditional concept of human beings on the types of missions performed by fighter jets, and enables people to have a new understanding of the combat capabilities of aerial refueling aircraft supporting fighter jets.

For the current hose-type aerial refueling method, due to the influence of atmospheric turbulence and the head wave generated by the precursor of the tanker, coupled with the flexibility of the refueling hose, the spatial position of the refueling drogue relative to the tanker cannot be fixed , there is a phenomenon of fluttering within a certain range; at the same time, more than 75% of the total resistance of the hose-type aerial refueling drogue is provided by the canopy, so the sinking amount of the awl depends on the windward area of the canopy. The refueling drogue has a certain amount of sinking at high speed and low speed. The canopy is divided into high-speed canopy and low-speed canopy. It is limited that the refueling machine can only operate at a certain speed after being equipped with a hose-type aerial refueling drogue equipment. The range can complete aerial refueling, which greatly limits the envelope of the tanker.

At present, there are three disadvantages in the soft aerial refueling method:

1. Due to the fluttering phenomenon of the taper sleeve, the refueling and docking link takes a long time;

2. When the refueling machine is close to the refueling drogue, the head wave of its precursor may induce the refueling drogue to vibrate, resulting in related refueling accidents;

3. The traditional hose-type aerial refueling drogue cannot realize the refueling of the tanker at high and low speeds, which greatly limits the refueling envelope of the tanker.

detailed description

The present invention will be described in further detail below in conjunction with accompanying drawings 1-3.

Embodiment: An aerial refueling drogue stabilization ring, as shown in Figures 1 to 3, includes 4 steering gears 9, 4 resistance surfaces 1 and a ring body 10; as shown in Figures 1 and 2, 4 The end of the resistance surface 1 is hinged with the end of the ring body 10; as shown in Figure 4, the side walls of the four resistance surfaces 1 near the inside of the ring body 10 are connected with resistance surface struts 5; the four steering gears 9 are all located In the ring body 10, the output shafts of the four steering gears 9 are connected with the steering gear rocker 6, and the end of the steering gear rocker 6 away from the steering gear 9 is connected with the end of the resistance surface strut 5 away from the resistance surface 1.

The battery 7 and the flight controller 2 are fixedly installed in the ring body 10 .

The end of the ring body 10 away from the resistance surface 1 is fixedly mounted with a tightening support 8 .

As shown in Figure 5, a jacking screw 3 is installed on the side wall of the jacking support 8, and the thread in the jacking support is connected with the jacking screw, and the ring body and the taper sleeve are connected together by the jacking screw.

Working principle: In the process of air refueling, when the tanker reaches the predetermined track, the drogue 11 is released. Under the action of resistance, the canopy opens and the ribs open. Corresponding cruising speed flight, after processing the speed and other data measured by the flight controller 2, control the four steering gears 9 to rotate at different angles, drive the steering gear rocker 6 to rotate at different angles, and the steering gear rocker 6 drives the resistance surface The struts of 1 produce different displacements, so that the four resistance surfaces 1 open at different angles around their rotation axes, and produce different windward areas in the direction of incoming flow, thereby generating different resistances and changing the resistance characteristics of the taper sleeve 11. Make the taper sleeve 11 have a certain amount of sinking at different speeds. When the oil receiving machine is a low-speed aircraft such as a helicopter, the resistance of the drogue 11 needs to be increased to reach the corresponding sinking position. By increasing the opening angle of the resistance surface 1, the resistance of the drogue 11 can be increased and the drogue can be increased. The sinking amount of 11 makes it reach the predetermined position; when the oil receiver is a jet aircraft, the drogue 11 needs to reduce the resistance to reach the corresponding sinking position, which can be reduced by reducing the opening angle of the resistance surface 1. The resistance of the small taper sleeve 11 reduces the sinking amount of the taper sleeve 11 to reach a predetermined position. During the release process of refueling, the speed, attitude and position of the drogue 11 measured by the flight controller 2 are used to control the four steering gears 9 to rotate at different angles, and to drive the steering gear rocker arm 6 to rotate at different angles. The arm 6 drives the struts of the resistance surface 1 to produce different displacements, so that the four resistance surfaces 1 open different angles around their rotation axes, and produce different windward areas in the direction of incoming flow, thereby generating different resistances and making the resistances produce differential resistances In order to control the posture of the taper sleeve 11, the taper sleeve 11 is stable during the entire release process. During this process, the oil receiver follows behind. When the taper sleeve 11 is released to the predetermined position, the oil receiver accelerates and approaches, and when it reaches the area, it slows down. Get closer, and at the same time stretch the oil receiving pipe to start docking with the taper sleeve 11. During the docking process of the oil receiving pipe and the taper sleeve 11, the steering gear 9 is controlled by the flight control 2 to rotate, so that the resistance surface 1 opens at different angles to suppress the differential force generated by the oil receiving machine. The head wave phenomenon produced by the precursor of the approaching refueling drogue 11 makes it complete the docking and start aerial refueling; Differential power, control the attitude of the drogue 11 to suppress its swing, recover the drogue 11 into the tanker, and complete the entire aerial refueling. This scheme is applicable to both manned and unmanned aerial refueling.
