Description

Technical Field

[0001] The utility model belongs to the field of aerial refueling, in particular to a refueling rod device used for confirming aerial refueling docking. Background Art

[0002] The most widely used aerial refueling system in the world is the hose-drogue refueling system.

[0003] The tanker releases the hose of the aerial refueling pod, and the refueling connector at the end of the hose opens a stable parachute canopy in the high-speed airflow, waiting for the refueling plug of the receiving aircraft to dock. A refueling rod extends near the nose of the receiving aircraft and moves forward relative to the tanker. The self-sealing valve on the top of the refueling rod pushes open the refueling connector, constructing the aerial refueling fuel passage, and refueling begins. However, the success of aerial refueling docking is currently judged only by whether there is a stable refueling flow. The instructions received by the refueler on the receiving aircraft are not timely and clear enough, which leads to wrong judgments. In addition, the existing technology has the following problems with unclear instructions:

[0004] 1) Before docking, when the fuel rod has not entered the refueling joint, the fuel rod has no contact with the contact, the signal circuit where the contact is located is not connected, and an indication of undocking (or no light on) is given;

[0005] 2) When the refueling rod just enters the refueling joint and the connection is not successful, the contact is lifted, the signal circuit is closed, and the connection indication (or light is on) is given;

[0006] 3) The refueling boom continues to advance and dock with the refueling connector. Two scenarios exist. If docking is successful, the contact will be depressed into the annular groove of the refueling boom, disconnecting the signal circuit again. Therefore, the signal indications during the entire docking process should be in the order of disconnected, connected (briefly), and disconnected. However, if an unexpected situation occurs and the receiving aircraft withdraws without docking, the contact will naturally be depressed, disconnecting the signal circuit again, and the signal indications will continue in the order of disconnected, connected (briefly), and disconnected. Utility Model Content

[0007] The technical problems of the utility model are:

[0008] Currently, the success of aerial refueling docking is judged only by whether there is a stable refueling flow. The instructions received by the refueling crew of the receiving aircraft are not timely or clear enough, which leads to wrong judgments.

[0009] The purposes of this utility model are:

[0010] In order to overcome the problem of unclear aerial refueling docking indication in the prior art, the utility model provides a device and method for detecting whether the aerial refueling docking is successful by using light indication. The successful aerial refueling docking is detected by converting the arrival signal when the docking is successful into a light signal that can be seen by the pilot.

[0011] The technical solution of the utility model is:

[0012] The utility model provides a refueling boom device for confirming aerial refueling docking, comprising a turbine generator, an LED lamp, contacts, and a cable. The turbine generator, LED lamp, contacts, and cables form an open circuit. When the aerial refueling docking is successful, the contacts are connected, the entire circuit becomes closed, and the LED lamp lights up, indicating a successful docking to the pilot of the receiving aircraft.

[0013] The above-mentioned fuel rod device for confirming aerial refueling docking can be improved on the basis of the existing fuel rod.

[0014] The above-mentioned refueling rod device for confirming aerial refueling docking is that when the refueling rod enters the refueling joint, the locking arm roller in the refueling joint is lifted up by the refueling rod and continuously rolls toward the rear of the refueling rod as the refueling rod moves forward until the locking arm roller falls into the groove of the refueling rod, indicating that the docking is successful.

[0015] In the above-mentioned refueling rod device for confirming aerial refueling docking, after successful docking, the locking arm roller is connected to the contact in the refueling rod groove, and the open circuit inside the refueling rod is connected.

[0016] The above-mentioned refueling rod device confirms the aerial refueling docking, and the turbine generator device generates electricity under the blowing of the aircraft's high-speed airflow to provide power supply for the LED lamp beads.

[0017] The advantages and beneficial effects of the utility model are:

[0018] As soon as the aerial refueling docking is successful, the docking success signal can be clearly fed back to the pilot of the receiving aircraft in the form of lights. There is no need to wait until a fuel path with a stable flow rate is established between the receiving rod and the refueling drogue before confirming the docking. BRIEF DESCRIPTION OF THE DRAWINGS

It is obvious that the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other, and the embodiments can refer to and quote each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] The receiving rod device for confirming aerial refueling docking includes a turbine generator device 3, an LED lamp bead 4, a contact 5 and a cable 6. Before the receiving aircraft docks, the turbine generator device 3, the LED lamp bead 4, the contact 5 and the cable 6 form an open circuit, such as Figure 2 During the docking process, the receiving aircraft approaches the refueling connector 1, and the refueling rod 7 enters the refueling connector 1. The locking arm roller 2 inside the refueling connector is lifted by the refueling rod 7 and rolls backward along the refueling rod 7 until the locking arm roller 2 moves into the groove of the refueling rod 7, pressing down the contact 5 in the groove of the refueling rod 7, so that the turbine generator 3, LED lamp bead 4, contact 5 and cable 6 form a closed circuit, as shown in FIG. Figure 1 As shown in the figure, turbine generator 3, under the action of high-speed airflow, powers LED lamp 4, illuminating it and providing a light indication to the pilot of the receiving aircraft. When the light is on, it indicates that the receiving aircraft has successfully docked; when the light is off, it indicates that the receiving aircraft has failed to dock.

[0026] This patent places the signal circuit contacts within the annular groove of the fuel rod. Only when the fuel rod is successfully docked and the locking arm is firmly pressed into the groove will the signal circuit be stably connected and the corresponding indication be given. If docking is unsuccessful, the signal circuit is always disconnected. This ensures a unique signal indicating successful docking, eliminating the possibility of misidentification.

[0027] When a traditional receiving aircraft performs aerial refueling docking, it is impossible to directly observe and determine whether the docking and locking action has been completed. It usually takes a period of time to discover that the docking and locking has not been completed through abnormal fuel transmission, which puts a heavy burden on the receiving aircraft. In order to overcome the problem that the aerial refueling docking indication in the prior art is not clear enough, the present utility model provides a device and method for detecting whether the aerial refueling docking is successful by using light indication. The device and method convert the arrival signal when the docking is successful into a light signal that can be seen by the pilot, thereby completing the detection of the success of the aerial refueling docking. The utility model can be improved on the basis of the existing receiving rod and implemented. It is convenient and fast, and can be applied to all domestic receiving aircraft with refueling capabilities, and has broad market prospects.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present invention, and these modifications or replacements should all be included in the protection scope of the present invention.
