Technical Field

[0001] This invention belongs to the field of unmanned vessel technology, specifically relating to an unmanned vessel powered by an aero-engine. Background Technology

[0002] Unmanned surface vessels (USVs) have high speeds and lack the steering rudders of traditional ships, thus posing greater challenges to their hull structure and aerodynamics. In particular, the instantaneous acceleration and steering vector changes of USVs make them very difficult to control; therefore, it is necessary to make USVs more stable and their steering more responsive. Summary of the Invention

[0003] In view of this, the present invention provides an unmanned vessel based on aero-engine power, which uses an aero-engine as its power source and makes full use of aerodynamics by setting up a canard system and a tail system to increase the attitude stability of the unmanned vessel at high speeds.

[0004] The present invention adopts the following technical solution:

[0005] An unmanned surface vessel powered by an aero-engine includes the unmanned surface vessel body, fuel tank, aero-engine, canard system and tail system;

[0006] The fuel tank is located in the front middle part of the unmanned vessel body;

[0007] The aircraft engine is located at the stern of the unmanned vessel.

[0008] The forewing system is located at the front top of the unmanned vessel body and is used to reduce the nose lift of the unmanned vessel body.

[0009] The tail fin system is located at the top end of the unmanned vessel body, and is used to increase the lift of the unmanned vessel body by the air and to generate a lateral force to assist the unmanned vessel body in turning.

[0010] Furthermore, the tail fin system includes a tail fin spoiler and a motion adjustment mechanism;

[0011] The upper surface of the tail spoiler is convex, and the lower surface is flat;

[0012] The motion adjustment mechanism can drive the tail spoiler to pitch and rotate and rise and fall.

[0013] Furthermore, the motion adjustment mechanism has a self-locking function, which can lock and fix the position of the tail spoiler.

[0014] Furthermore, the tail fin system also includes tail fin support plate I, tail fin support plate II, and supporting web plate;

[0015] The tail fin support plate I and the tail fin support plate II are symmetrically arranged about the longitudinal axis of the unmanned vessel body at the tail end of the top surface of the unmanned vessel body.

[0016] The two ends of the supporting web are respectively connected to the tail fin upright plate I and the tail fin upright plate II;

[0017] The motion adjustment mechanism is connected in parallel to the supporting web plate;

[0018] The lower surface of the tail spoiler is connected to the motion adjustment mechanism.

[0019] Furthermore, the motion adjustment mechanism includes an auxiliary branch and at least two power branches;

[0020] The auxiliary branch is located in the middle of the supporting web. The bottom of the auxiliary branch is connected to the supporting web through a ball joint, and the upper part is connected to the lower surface of the tail spoiler through a linear drive electric cylinder.

[0021] The bottom of the power chain is connected to the support web via a ball joint, and the upper part is connected to the lower surface of the tail spoiler via a ball joint. The upper and lower parts are also connected by a linear drive electric cylinder.

[0022] Furthermore, the canard system includes a canard spoiler, canard vertical plate I, canard vertical plate II, a rotating mechanism, and a braking mechanism;

[0023] The front wing vertical plate I and the front wing vertical plate II are symmetrically arranged at the front end of the top of the unmanned vessel body about the longitudinal axis of the unmanned vessel body;

[0024] The upper surface of the forewing spoiler is flat, and the lower surface is convex. The forewing spoiler is rotatably connected to the forewing vertical plate I and the forewing vertical plate II via a rotating shaft.

[0025] The rotating mechanism includes a motor, which is supported and mounted on the front wing upright plate I. The motor can drive the front wing spoiler to rotate around the axis of the rotating shaft.

[0026] The braking mechanism includes a power-off electromagnetic brake, which is supported and mounted on the front wing vertical plate II and is used to lock the rotation of the front wing spoiler.

[0027] Furthermore, the forewing spoiler, the forewing vertical plate I, the forewing vertical plate II, the rotating shaft, the tail wing vertical plate I, the tail wing vertical plate II, the supporting web, and the tail wing spoiler are all made of carbon fiber reinforced polyetheretherketone material, and are coated with a reinforcing coating.

[0029] 1. The fuel tank is located in the front middle part of the unmanned vessel body; the aero engine is located in the stern of the unmanned vessel body; the canard system is located at the front top of the unmanned vessel body to reduce the nose lift of the unmanned vessel body; the tail fin system is located at the rear top of the unmanned vessel body to increase the lift of the air on the unmanned vessel body and to generate lateral force to assist the unmanned vessel body in turning.

[0030] Thus, because aero engines are the power source for jet aircraft, possessing the characteristics of powerful performance and rapid response, they have advantages that traditional power sources cannot match. A large number of retired aero engines from recent decades still exist, and using them as a power source for unmanned surface vessels (USVs) can improve the speed and maneuverability of existing USVs. Furthermore, the canard and tail fin systems can fully utilize aerodynamics, increasing the attitude stability of USVs at high speeds.

[0032] In this way, through the coordinated action of the auxiliary chain and the power chain, the tail spoiler can rise and fall in the height direction (Z-axis direction), pitch and rotate in the front-to-back direction (X-axis direction) and left-to-right direction (Y-axis direction), and rotate around the Z-axis. Thus, the tail spoiler can achieve the adjustment needs of the unmanned vessel at different attitudes and speeds through beneficial turbulence.

Detailed Implementation

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] like Figures 1-10 As shown, an unmanned surface vessel powered by an aero-engine includes an unmanned surface vessel body 03, a fuel tank (not shown), an aero-engine (not shown), a canard system 01, and a tail system 02, wherein:

[0048] The fuel tank is located in the front middle part of the unmanned vessel body 03; the aero-engine is located in the tail of the unmanned vessel body 03; the canard system 01 is located at the front top of the unmanned vessel body 03 to reduce the nose lift of the unmanned vessel body 03 (the aero-engine is located in the tail of the unmanned vessel body 03, and the fuel tank is in the front middle part. As the speed increases and the fuel is consumed, the center of gravity moves towards the tail, resulting in the unmanned vessel body 03 tilting its nose up); the tail fin system 02 is located at the rear top of the unmanned vessel body 03 to increase the lift of the unmanned vessel body 03 and to generate lateral force to assist the unmanned vessel body 03 in turning.

[0049] Thus, because aero engines are the power source for jet aircraft, possessing the characteristics of powerful performance and rapid response, they have advantages that traditional power sources cannot match. A large number of retired aero engines from recent decades still exist, and using them as a power source for unmanned surface vessels (USVs) can improve the speed and maneuverability of existing USVs. Furthermore, the canard system 01 and tail system 02 can fully utilize aerodynamics to increase the attitude stability of USVs at high speeds.

[0050] Specifically, the tail fin system 02 includes a tail fin spoiler 21 and a motion adjustment mechanism 24; the upper surface of the tail fin spoiler 21 is convex, and the lower surface is flat; the motion adjustment mechanism 24 can drive the tail fin spoiler 21 to pitch and rotate and rise and fall. The motion adjustment mechanism 24 has a self-locking function, which can lock and fix the position of the tail fin spoiler 21. The tail fin system 02 also includes a tail fin support plate I22, a tail fin support plate II23, and a supporting web plate; the tail fin support plate I22 and the tail fin support plate II23 are symmetrically arranged about the longitudinal axis of the unmanned vessel body 03 at the top aft end of the unmanned vessel body 03; the two ends of the supporting web plate are respectively connected to the tail fin support plate I22 and the tail fin support plate II23; the motion adjustment mechanism 24 is supported in parallel on the supporting web plate; the lower surface of the tail fin spoiler 21 is connected to the motion adjustment mechanism 24. The motion adjustment mechanism 24 includes an auxiliary branch 24-1 and at least two power branches 24-2. The auxiliary branch 24-1 is located in the middle of the supporting web. The bottom of the auxiliary branch 24-1 is connected to the supporting web via a ball joint, and the upper part is connected to the lower surface of the tail spoiler 21 via a linear drive electric cylinder. The top of the auxiliary branch 24-1 has a mounting flange, which is connected to the threaded hole machined on the tail spoiler 13 via screws. The bottom of the power branches 24-2 is connected to the supporting web via a three-degree-of-freedom ball joint bearing (ball joint), and the upper part is connected to the lower surface of the tail spoiler 21 via a three-degree-of-freedom spherical bearing (ball joint). The upper and lower parts are also connected by a linear drive electric cylinder (linear sliding pair). In this embodiment, there are four power branches 24-2, which are arranged in a trapezoidal shape.

[0051] Thus, through the coordinated action of auxiliary branch 24-1 and power branch 24-2, the tail spoiler 21 can rise and fall in the height direction (Z-axis direction), pitch and rotate in the forward and backward direction (X-axis direction), pitch and rotate in the left and right direction (Y-axis direction), and rotate around the Z-axis. This beneficial disturbance by the tail spoiler 21 allows for adjustments to the unmanned surface vessel at different attitudes and speeds. Specifically, as the unmanned surface vessel's speed increases, the tail system 02 can rise as a whole. The tail spoiler 21 generates a reaction force through airflow, increasing the lift of the unmanned surface vessel. Simultaneously, through the coordinated action of power branch 24-2 and auxiliary branch 24-1, the angle of contact between the tail spoiler 21 and the air can be adjusted, achieving control at different speeds and under different conditions. Furthermore, when the unmanned surface vessel uses aero-engine steering vector control, the tail spoiler 21 can be controlled to generate lateral force, assisting in steering and increasing the stability of the unmanned surface vessel during steering.

[0052] Specifically, the canard system 01 includes a canard spoiler 13, a canard vertical plate I11, a canard vertical plate II12, a rotation mechanism 14, and a braking mechanism 15. The canard vertical plates I11 and II12 are symmetrically arranged about the longitudinal axis of the unmanned vessel body 03 at the front top of the unmanned vessel body 03. The upper surface of the canard spoiler 13 is planar, and the lower surface is convex. The canard spoiler 13 is rotatably connected to the canard vertical plates I11 and II12 via a rotation shaft. The rotation mechanism 14 includes a motor, which is supported and mounted on the canard vertical plate I11. The motor can drive the canard spoiler 13 to rotate around the axis of the rotation shaft. The braking mechanism 15 includes a power-off electromagnetic brake, which is supported and mounted on the canard vertical plate II12 and used to lock the rotation of the canard spoiler 13. The canard system 01 has a simple and compact structure.

[0053] In addition, the forewing spoiler 13, forewing vertical plate I11, forewing vertical plate II12, rotating shaft (integrated machining), tail wing vertical plate I11, tail wing vertical plate II12, supporting web plate, and tail wing spoiler 21 are all made of carbon fiber reinforced polyetheretherketone material, and the surface is coated with a reinforcing coating. It has the advantages of low density, high strength, and good rigidity, and is lightweight while taking into account the mechanical performance of withstanding high-speed airflow.

[0054] More specifically, this invention, based on unmanned high-speed vessels powered by aero-engines, fully utilizes hydrodynamics to enhance adaptive assisted control of the unmanned vessel at different speeds and attitudes. This increases the unmanned vessel's attitude stability at high speeds and provides auxiliary power during turning, making the unmanned vessel more stable and reliable, and improving its motion performance and control stability. The adaptive nature is reflected in the fact that, under different states, speeds, and attitudes of the unmanned vessel, the forewing system 01 and tail wing system 02 can provide different action responses according to the action requirements and algorithms, giving the unmanned vessel superior dynamic performance at high speeds. The forewing system 01 can adjust the angle of the forewing spoiler 13, creating beneficial disturbances through the airflow during high-speed movement to assist in adjusting the bow attitude. The unmanned vessel's steering is mainly achieved through tail vector control of the aero-engine. Compared to rudder control, aero-engine vector control is more difficult. Through attitude adjustment by the forewing system 01, beneficial auxiliary adjustments can be achieved through aerodynamics, enabling precise steering. In this embodiment, the unmanned vessel's maximum speed can reach 150 knots.

[0055] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
