Description

Wing structure of flying wing boat

This creation relates to a wing structure of a flying-wing boat, especially a wing-connecting structure of a flying-wing boat. New creations towards mobility.

"Flying wing boat" is a mixture of aviation and navigation technology. Its English name is Wing In Ground Effect Vehicle (WIG for short). As shown in Figure 1, a known flying wing boat is revealed. The wing boat has a fuselage and a pair of wings. The difference from the seaplane is that the flying wing boat has no buoys and lands on the water with the belly or water skids; The unique ground effect (Ground Effect) produced when the wing is close to the water surface makes the lift of the wing greatly increased, but the drag is reduced, so that less power is required, that is, fuel consumption is reduced to achieve water transportation The most difficult high-speed characteristics, and the advantages of maintaining the original high carrying capacity.

At present, the operation process of the "Flying Wing Ship" will generally experience the following four states. 1. Low-speed taxiing period: its sailing state is the same as that of a surface ship, and the lower half of the body is designed like a boat, so it is easy to control. 2. Preparing for acceleration period: In order to quickly bring the body into the range of ground effect to save time, fuel consumption and body resistance; but before it takes off and officially enters the stage of ground effect, its resistance will increase. Needed propulsion is 2 times to 3 times of general cruising propulsion, that is, the thrust required for the take-off of the flying wing boat must wait to be reduced after entering the ground effect stage. 3. Ground effect stage: When the speed is between 120-500km/h, the ground effect force will naturally be generated between the lower plane of the wing and the water surface, so that the flying wing boat can skim above the water surface with low resistance. 4. Response methods in the face of special situations: when the flying wing boat encounters an obstacle or evades an unexpected situation, the response that can be taken is roughly turning sideways to flash over the obstacle, or raising the flying height of the flying wing boat to cross the obstacle.

However, the time for the flying wing craft to skim on the horizontal plane at the above-mentioned high speed is very limited. Therefore, the directions for further research and development of the flying wing craft are as follows: 1. Strengthen the air/hydrodynamic force of the flying wing craft before taking off Design and maintain the stability of ground effect flight on the water surface; 2. Improve the dynamic stability of flying wing boats when they climb instantly or turn sideways during flight.

In view of this, this creation system will provide a kind of flying wing boat structure with good climbing ability and lateral movement ability.

In order to achieve the above purpose, this creation provides a wing structure of a flying wing boat. The flying wing boat structure includes a fuselage and a pair of front wings. The shape of the fuselage conforms to the design of aerodynamics and hydrodynamics, and has appropriate buoyancy; The pair of front wings are arranged on both sides of the fuselage, and the front wings extend outwards and form an appropriate sweep angle backward; the feature is: the structure also includes a pair of rear wings, which are formed by the fuselage Both sides of the tail end extend out and form an appropriate forward sweep angle forward; the wing ends of the front wing and the rear wing are connected to each other.

The improvement of the structure of the above-mentioned flying wing boat, wherein the front wing and the rear wing are respectively located at different heights at the front and rear of the fuselage.

The improvement of the structure of the above-mentioned flying wing boat, the structure further includes a vertical wing, which is arranged at the wing ends of the front wing and the rear wing to connect the front wing and the rear wing.

The improvement of the structure of the above-mentioned flying wing boat, the structure further includes a water ski, and the water ski is arranged under the vertical wing.

After implementing the above structure, it can be seen that this creation improves the structural strength and cruising stability of the flying wing boat, and at the same time has the motion performance of rising, falling, or horizontal skidding at a pitch angle of zero degrees, which greatly improves the dexterity of control.

In order to further understand the structural features, effects and other advantages of this creation, a preferred embodiment and accompanying drawings are described in detail below.

First of all, please refer to Fig. 2 and Fig. 3, which are the preferred embodiments of the wing structure of the flying wing boat of this invention. The flying wing boat includes: a fuselage 10, and the shape of the fuselage 10 conforms to aerodynamics And the design of hydrodynamics, itself has appropriate buoyancy, is provided with at least one propeller 11 on the fuselage 10, so as to produce the power that promotes the flying wing boat whole to move forward; On both sides, the front wing 20 extends outwards and forms an appropriate sweep angle backward; a pair of rear wings 30 extend from both sides of the rear end of the fuselage 10 and form an appropriate forward sweep forward. Angle; a vertical wing 40 is arranged at the wing tip (Wing Tip) of the front wing 20 and the rear wing 30, so that the front wing 20 and the rear wing 30 are formed at the wing tip by different heights of the front and rear of the fuselage 10 Interconnected configuration; a water skid 50 is further provided below the vertical fin 40 to provide assistance in maintaining the balance of the hull. Of course, the water skid 50 is not limited to the above-mentioned position, the airfoil between the water surface and the wing The following can be set in general.

After this creation is implemented according to the above structure, since the end of the second wing is strengthened by the vertical fins 40, the bending moment on the wing can be reduced, and the wing root of the second wing can greatly reduce the The stress carried by the beam (Wing Spar), so the wingspan of the two wings (Wing Span) can be designed to be larger than the wingspan of a traditional aircraft, and because the flying wing boat of this wing configuration has higher strength, Therefore, the design requirement of the structural strength itself can also be reduced, which helps to reduce the production difficulty of the flying wing craft. In view of the large wingspan of the winged boat of this creation, and the two pairs of front and rear wings have vertical vertical fins at the wing ends, which block the flow of the three-dimensional airflow at the wing ends, so it can be greatly reduced. The strength of the Wing Tip Vortex reduces the induced drag.

In addition, because the winged boat of this invention has two pairs of wings, two pairs of elevators and two pairs of ailerons can be installed at the same time. If the two pairs of elevators and ailerons operate simultaneously and the forces are coupled Next, the flying wing boat in the wing configuration can rise or fall at a zero pitch angle (Pitch Angle) as shown in Figure 4, or as shown in Figure 5, make a sideslip movement perpendicular to the flight direction (Sideslip ); These sports modes can provide better dynamic handling performance and greatly improved stability for avoiding obstacles or responding to unexpected situations, and also contribute to the safety of take-off and landing or cruising.

The winged structure of the flying-wing boat of this creation, after comparing with the known flying-wing boat structure, has the following characteristics at least: 1. The wing with the larger aspect ratio (Aspect Ratio) provides better aerodynamic force, has better Large lift, small induced resistance, further increase the flight time and flight height and stability of the flying wing boat. 2. The structure is light in weight and has dexterous movement characteristics, which can generate direct lift or lateral force and improve control performance. 3. The aircraft structure with increased strength has a higher payload capacity, which can increase its fuel carrying capacity and install aerial survey instruments.

It can be seen from the description of the above embodiments that this creation has indeed achieved the preset purpose, and fully meets the industrial utilization and patent requirements. It is necessary to file a patent application according to law, but the above description is only a preferred embodiment of this creation, not for This creation is limited, so the scope of protection of this creation should be defined by the scope of the attached patent application.
