Description

Technical Field

[0001] The invention relates to the field of aerospace technology, and in particular to a gliding airdrop type unmanned sailboat. Background Art

[0002] As the conditions for using solar airships for sea observation become more mature, the use of solar airships to drop falling payloads for detection will also be realized. The currently used falling payloads include uncontrollable delivery methods such as parachuting and free fall, and controllable delivery by airdrop gliders. Uncontrollable delivery methods have disadvantages such as uncontrollable routes and landing points and short delivery distances, while controllable delivery aircraft have limited gliding time and cannot land on water for surface observation tasks.

[0003] Airdropped watercraft have disadvantages such as uncontrollable routes and landing points and short drop distance. If the watercraft uses propeller propulsion, there are also problems such as short flight time and difficulty in long-term coordinated observation with solar airships.

[0004] The existing technology lacks an unmanned sailboat that can achieve both fixed-point delivery and long-term endurance to complete observation tasks. Summary of the invention

[0005] The purpose of the present invention is to provide a gliding airdrop type unmanned sailboat, which has a long delivery distance and high landing point accuracy. After landing on the water, it can use wind power to navigate with low energy consumption, and can achieve rapid and accurate arrival in a large range and long-term coordinated observation of air and sea.

[0006] To achieve the above-mentioned objectives, the present invention provides a gliding airdrop type unmanned sailboat, comprising a first unmanned sailboat device and a second unmanned sailboat device, wherein the first unmanned sailboat device and the second unmanned sailboat device are symmetrically distributed, the first unmanned sailboat device is provided with a mainsail, one side of the mainsail is provided with an aileron, one end of the aileron is provided with a tail wing strut, one end of the tail wing strut is sleeved on the mainsail, and the other end thereof is provided with a vertical tail wing, and the vertical tail wing is provided with a rudder.

[0007] Preferably, one end of the mainsail is connected to one side of the pontoon, and both ends of the other side of the pontoon are respectively provided with underwater pillars and horizontal tail fins, the underwater pillars and horizontal tail fins are both connected to the joint casing, and the horizontal tail fin is provided with an elevator.

[0008] Preferably, the buoyancy box is connected to the mainsail via a mainsail rotating shaft and a mainsail pin shaft arranged at both ends of the buoyancy box.

[0009] Preferably, a first double-ship joint assembly is provided on the other side of the joint casing.

[0010] Preferably, the first double-ship joint component on the first unmanned sailboat device is connected to the second double-ship joint component provided on the second unmanned sailboat device.

[0011] Therefore, the present invention adopts the above-mentioned gliding airdrop type unmanned sailboat, and its technical effects are as follows:

[0012] (1) The gliding delivery capability extends the delivery distance of the unmanned boat and increases the delivery accuracy.

[0013] (2) The ability to use wind power for water navigation reduces the power required for navigation, allowing unmanned vessels to sail for long periods of time.

[0014] (3) The capabilities of the present invention are conducive to rapid and accurate deployment, and are conducive to long-term coordinated observation with airborne platforms such as airships.

[0015] (4) The solution adopted by the present invention requires fewer moving parts during the air-to-water conversion stage and is simple and reliable.

When in the air, a first double-ship joint assembly 13 provided on the first unmanned sailboat device 1 is connected to a second double-ship joint assembly 22 provided on the second unmanned sailboat device 2.

[0028] The first unmanned sailboat device 1 is provided with a main sail 3, a side of the main sail 3 is provided with an aileron 12, one end of the aileron 12 is provided with a tail wing support rod 9, one end of the tail wing support rod 9 is sleeved on the main sail 3, and the other end is provided with a vertical tail 10, and a rudder 11 is provided on the vertical tail 10. The buoyancy box 4 is connected to the main sail 3 through a main sail rotating shaft 14 and a main sail pin shaft 15 provided at both ends of the buoyancy box 4.

[0029] One end of the mainsail 3 of the first unmanned sailboat device 1 is connected to one side of the pontoon 4, and the two ends of the other side of the pontoon 4 are respectively provided with underwater pillars 5 and horizontal tail 7, the underwater pillars 5 and the horizontal tail 7 are both connected to the joint casing 6, and the horizontal tail 7 is provided with an elevator 8, and the other side of the joint casing 6 is connected to the first protrusion 16 provided on the first double-ship joint assembly 13.

[0030] like Figure 5 As shown, a first connecting piece 17 is provided on the first protrusion 16, a first through hole 18 and a second through hole 19 are provided at both ends of the first connecting piece 17, a first groove 20 is provided on one side of the first protrusion 16, the first groove 20 is provided on the joint casing 6, and a second groove 21 is provided in the first groove 20.

[0031] A second protrusion 23 is provided on the second double-ship joint component 22 arranged on the second unmanned sailboat device 2, and the second protrusion 23 is the same as the first protrusion 16 on the first double-ship joint component 13. A second connecting piece 24 is provided on the second protrusion 23, and the second connecting piece 24 is the same as the first connecting piece 17 on the first double-ship component 13. A third through hole and a fourth through hole are provided at both ends of the second connecting piece 24. A third groove 25 is provided on one side of the second protrusion 23, and the third groove 25 is the same as the first groove 20 on the first double-ship component 13. A fourth groove 26 is provided in the third groove 25, and the fourth groove 26 is the same as the second groove 21 on the first double-ship component 13.

[0032] When the first unmanned sailboat device 1 and the second unmanned sailboat device 2 are connected, the first groove 20 provided on the first double-ship joint component 13 is sleeved on the second protrusion 23 provided on the second double-ship joint component 22, the second groove 21 is sleeved on the second connecting plate 24, the first protrusion 16 is connected to the third groove 25, and the first connecting plate 17 is connected to the fourth groove 26.

[0033] The first unmanned sailboat device 1 and the second unmanned sailboat device 2 are connected together to form a glider, which is launched from an aerial platform, flies to a predetermined area based on a satellite navigation system and an automatic control system, and lands on water in the predetermined area. During this period, the mission payload performs an aerial mission.

[0034] The mainsail 2 adopts a symmetrical airfoil and serves as the main wing of the glider in the air. It is fixed to the pontoon 4 by the mainsail shaft 14 and the mainsail latch 15. The outer section of the mainsail 3 has ailerons 12 to provide rolling control. The underwater support 5 between the pontoon 4 and the joint casing 6 also adopts a symmetrical airfoil and serves as the inner wing section to provide partial lift in the air. The rear underwater wing surface (horizontal tail 7 and elevator 8) adopts a symmetrical airfoil and serves as the horizontal tail 7 in the air. The vertical tail 10 is connected to the mainsail 3 by the tail stay 9. The mainsail 3 is provided with a rudder 11 to provide heading stability and maneuverability.

[0035] When Figure 2 After landing in the form shown, the joint between the first unmanned sailboat device 1 and the second unmanned sailboat device 2 is unlocked, and the two boats are separated. The separated unmanned boat is erected under the action of the moment formed by gravity and buoyancy, so that the main sail 3 is perpendicular to the water surface, as shown in FIG. Figure 3 The rotating shaft on the tail wing support rod 9 is unlocked, and the vertical tail wing 10 rotates to be parallel to the main sail 3 under the action of gravity and is locked, as shown in FIG. Figure 4 The mainsail latch 15 is unlocked, so that the mainsail 3 can rotate freely, completing the empty-water conversion. Figure 5 shown.

[0036] On the water, the first unmanned sailboat device 1 and the second unmanned sailboat device 2 use the buoyancy box 4 to provide the main buoyancy, and the center of gravity thereof is below the buoyancy box 4, providing a moment to keep the main sail 3 vertical. The underwater parts of the first unmanned sailboat device 1 and the second unmanned sailboat device 2 have high lateral damping and heading stability, which can ensure that the bow of the unmanned boat points to the sailing direction relative to the water body. Through the rear elevator 8, the first unmanned sailboat device 1 and the second unmanned sailboat device 2 can perform heading control.

[0037] After the mainsail latch 15 on the water is unlocked, the mainsail 3 is connected to the mainsail shaft 14 provided on the pontoon 4, and the mainsail 3 can rotate freely. The vertical tail 10 rotates to a position parallel to the mainsail 3 and is locked, providing a torque to make the mainsail 3 parallel to the wind direction under the action of wind. Through the rudder 11 and aileron 12 on the vertical tail 10, a torque is formed to deflect the mainsail 3 in the corresponding direction under the action of wind, forming an angle of attack and generating lateral lift. If the component of the lift in the bow direction is positive, the unmanned boat obtains forward thrust. By controlling the heading of the boat, the deflection of the vertical tail 10 and the mainsail 3 through the automatic control system, the first unmanned sailboat device 1 and the second unmanned sailboat device 2 can be made to sail forward.

[0038] Therefore, the present invention adopts the above-mentioned gliding airdrop type unmanned sailboat, which has a longer delivery distance and higher landing point accuracy. After landing on the water, it can use wind power to navigate with low energy consumption, and can achieve rapid and accurate arrival in a large range and long-term coordinated observation of air and sea.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
