Description

Ground effect carrier with front and rear wing type

Wing In Ground Effect Vehicles (WIGs) are known as ground-effect vehicles. When the vehicle is flying in the air, the airfoil lift must be used to overcome its own weight and the various resistances to the air movement by the airfoil. The so-called "Wing In Ground Effect" The phenomenon is that when the bottom of the wing is close to the ground or the water surface, the airflow flowing under the wing is compressed by the airfoil and the ground to increase the pressure, so that the wing gains additional lift, and the flight performance of the vehicle increases. The fuel consumption rate is relatively reduced; when the vehicle application field is on the water, it has the function of the ship, and this effect can be used to achieve the most difficult high-speed characteristics of the water bearing.

The conventional ground effect vehicle has two wings front and rear (Tendem). Please refer to the first figure in the figure. A ridged hull type with a hydrodynamic lift is installed in the lower part of the body. The performance is lower than that of the hydrofoil, and the bottom of the ship is immersed in the water when the body is stopped. Although this shape helps to reduce the surface resistance and quickly bring the body into the ground effect range, it starts from the acceleration process. In the surface stage, the engine still needs to be propelled by a higher power speed than when it is in the ground take-off phase. It can get rid of the liquid surface adhesion, and the wings of the front and rear main wings are both short and wide, and the wing's airfoil lifts. The application efficiency is low.

For the improvement of the prior art, the application of the airfoil configuration enhances the airfoil lift and combines the ground effect to make the aerodynamics perform better.

In view of this, the present invention provides a ground effect carrier having a forward-swept wing front and rear arrangement, the structure comprising: a body, the external body type conforms to aerodynamics and fluid mechanics design, has appropriate buoyancy; a pair of front Sweeping the wing and forming an appropriate forward sweep angle forward; a pair of wings, located below the nose, with hydrofoil function; a pair of structural reinforcements extending from both sides of the middle section of the body; Buoyancy for the web; a pair of ridge-shaped hull-type pontoons; one empennage; an engine mounting frame; and a wing support column.

The ground effect carrier described in the present invention is provided with a pair of wings 70 below the machine head, and is connected with the connecting plates 50 on the left and right sides to assume the role of structural support, and assists in suppressing the occurrence of buoys on the left and right sides of the traveling room. Torque moment.

The effect of hydrodynamic lift is that the hydrofoil is superior to the ridge-like hull type. The above-mentioned wing 70 provides the function of the body to lean down, and when the propulsion is advanced, the effect of hydrodynamic lift is generated at an appropriate speed. The function of the wing assists the vehicle to quickly leave the water surface; when landing, the function of the water raft can be generated due to the guiding effect of the hydrofoil placement angle, and the gliding function can be stopped to the stop state, and the pontoon or float is also caused by the hollow structure. The function of the board keeps the posture of lifting off the water surface even in the first half of the vehicle in the stop state; the setting of the wing 70 enables the engine to use the lower power to get the vehicle out of the water surface and to take off at a short distance.

The creation system provides a structure reinforcing frame 21 end through a connecting wing, has the function of strengthening the wing structure, and the function of generating the air collecting port through the configuration, so that the airflow can accelerate the flow rate on the surface of the wing to increase the negative pressure to generate greater lift; It has the function of leading edge slot (Slat), which enables the wing to have the ability to delay airflow separation; to reduce air resistance, airfoil can produce liters Force, the wing combined with the bottom is added to the same wing area.

The structural reinforcement frame 21 includes the suspension frame as a suspension hanger. In the embodiment of the second embodiment, the engine is installed under the structural reinforcement frame 21. When the engine running power is gradually increased, the airflow is accelerated and pushed through the lower wing surface. The increased negative pressure on the airfoil increases the effectiveness of the lift.

The present invention provides a forward-swept wing 20 whose grazing angle advances to form an appropriate angle, and an interface connecting the structural reinforcing frame 21 at an appropriate distance from the leading edge of the wing becomes a tangentially swept airfoil. The wing end is a triangular airfoil 22, which can become a vortex generator when the elevation angle of the fuselage caused by sudden environmental factors is too high, and provides a vortex lift to assist in correcting the stable posture of the body.

The two side connecting plates 50 of the present invention are a hollow structure with buoyancy, combined with the ridge-shaped hull-type pontoon 51, and combined with the forward-swept wing 20 and the wing 70 to enhance the strength of the wing structure and can withstand The rebounding force of the water surface after tapping, the connecting plate 50 has the function of reducing the wing vortex (Wingtip Vortices), the ridge-shaped hull type pontoon 51 assists the head of the machine to lift off the water surface, and the pontoon itself has buoyancy when the vehicle is stopped. Can support the entire set of vehicles floating on the water.
