Description

The Ornithopter Attached Slide Apparatus}

The present invention incorporates a slide device in the fuselage of the winged wing and moves the wing to the center of gravity relative to the aerodynamic center by moving an accessory or any object disposed therein. The present invention relates to a vehicle flying with wing gestures with improved control by allowing flight posture and flight direction of the aircraft to be adjusted.

The research on ornithopters with flapping motions has been conducted since 1490 by Leonardo da Vinci. It has been going on. Existing flapping-wing aircraft have been produced by fixing the center of gravity and the aerodynamic center from the time of manufacture. Recently, a patent has been filed under the name 'aircraft flying by the wing' (Publication No. 1999-0064660). It includes a fuselage part and a power part, and a wing part that generates lift and buoyancy by being combined to rotate up and down at an angle to the center line so that the wing can be moved up and down by flying the wings up and down like an insect or a bird. It is characterized in that, but the position of the center of gravity is fixed. 'Bat wing flyer' and 'Sky-High Butterflys', which are commercialized and sold in the United States, fly wing with rubber bands as a power source, and are designed to not change the center of gravity. In addition, 'Flying bird', which is sold by Schylling in the US, is a bird-like ornithopter (flapping-wing aircraft) that can fly only a few seconds using rubber power and its center of gravity is fixed. As described above, various Ornithopters are commercialized and sold, but the center of gravity position is fixed and the method of controlling the vehicle in a flight position by changing the position of the center of gravity of the aircraft flying by the wing movement as the present invention using a slide device. No idea of a winged vehicle has been devised or released as a commodity.

Conventional fixed-wing aircrafts have fixed wings and generate lift vertically in the direction of flight, so they are fast and mainly fly forward, while winged aircrafts can hover and ascend in accordance with flight posture and winging. Therefore, there is a feature that can apply the technology to change the flight direction by changing the flight attitude. Therefore, the present invention is equipped with a slide device that allows the user to easily change the position of the center of gravity of the winged wing that is not applied in fixed wing aircraft by changing the position of the center of gravity of the winged wing and flight direction How to control the will apply. Therefore, the user should understand the flight principle of the bird (bird) and apply it to create a product that can control the winged aircraft. The flapping wing of a bird or insect performs essential movements such as vertical and vertical movements, horizontal movements in front and rear, and twisting movements of the wings. These birds and insects weigh from a few milligrams to 100 kilograms (Kg), and wing spans range from 1.3 cm to 10.0 m, but flapping wings are fairly complex. Because winged aircraft that flap like these birds and insects are different from fixed wing aircraft, they can improve their maneuverability by creating slide devices that can change their center of gravity to distribute thrust, lift, buoyancy and drag during the flapping cycle. have.

There are a number of problems to be solved in wing-finging aircraft, such as aerodynamic problems, aircraft structure problems, flapping wing driving problems, and steering problems. The position of the center of gravity can be moved according to the aerodynamic force and aerodynamic center position of the winged aircraft, and the slide device can change the position of the center of gravity within the above center of gravity movement range. Should be manufactured. Therefore, the user should check the flight attitude and flight direction of the winged aircraft while the user has fixed the center of gravity position of the winged aircraft and has the flapping movement. The aircraft structure must maintain the wing skin well attached to the wing structure (skeleton) during the flapping movement. In addition, the problem of increasing the moment of inertia during flapping movement should be solved, and the gearbox to transmit the power to drive the blade should be solved because it increases the weight and reduces the efficiency of the power. If the flapping amplitude of the wing motion and the power dissipation of the engine power change, the relative position of the tail blades affecting stability and maneuverability must also be changed. Tail-wing control is commonly used by electro-mechanical systems or by manual fixation. Therefore, if you make and sell winged toy toys that can perform additional control by changing the position of the center of gravity of a winged wing with complex movements, you will be able to inspire children and improve your brain.

The present invention is equipped with a slide device that can change the position of the center of gravity by moving the position of the accessory or any object to the winged aircraft performing the flapping motion, the user can easily change the flight attitude The present invention relates to a winged wing slide device that can improve the imagination and the inquiry ability while developing the brain by manipulating the winged wing vehicle. When described in detail with reference to the accompanying drawings with respect to the slide device of the flying wing flying according to the present invention as follows.

Figure 1 shows the configuration of the aircraft and the slide device flying in the wing frame according to the present invention. The aircraft according to the present invention; A fuselage unit 3 including a power transmission unit 1, a power unit 2, and other device units; A slide device (4) mounted to the bottom of the fuselage and capable of moving any weighted objects (e.g. batteries) disposed therein; A power unit 2 composed of a power source and a power device (such as a motor), a power transmission unit 1 connected to the power unit; A wing part and a wing structure part 5 made of a flexible luminous cloth connected to a power transmission part and having an airfoil shape; Tail wing portion 6 that can adjust the direction of flight with the slide device; It consists of the other apparatus part 7, etc. which can mount a small camera, a small video camera, a voice generator, etc. in a fuselage | body part. In addition, the present invention can be remotely controlled wing wing by attaching a servo, a receiver, a wireless remote controller 8 and the like according to a wireless control. The fuselage part 3 is made of light wood (eg, shot) or synthetic resin, or composite material, carbon, light alloy, or the like. Power units disposed inside and below the fuselage can be selected from, or a combination of, power sources such as rubber bands, compressed air, engines, motors, chemicals, electrical forces, propellants, springs, and solar power. In accordance with an embodiment of the present invention, a motor and a battery can be used, and the position of the battery can be changed so that the center of gravity can be moved according to aerodynamic center change according to the wing design. In the case of using rubber power, an arbitrary weighted object is disposed inside the slide device to move the center of gravity. The power transmission unit 1 is basically a device that changes the circular motion into a linear motion and adds a torsional motion or elliptical motion of the wing itself. As an example of the power transmission unit, by connecting the crank and connecting rod to the disc connected to the motor shaft, it is possible to change the circular motion of the motor into linear up and down motion or to elliptic motion combined with linear up and down motion, horizontal motion and torsional motion. Use the giving method. In addition, the wing wing according to the present invention was able to adjust the amplitude of the flapping by adjusting the position and length of the crankshaft. The power transmission unit 1 should be provided with one or more gear gears so that the rotational speed of the motor can be reduced and transmitted, and a small bearing should be installed so that the crank and connecting rod system can move smoothly without friction. Two or more pairs of wings 5 generating lift and thrust through the wing are mounted on the fuselage, and a wing structure (skeleton) supporting the wings at right angles is attached to the fuselage. Tail wing portion 6 can control the flight direction with the slide device (4) that can move the center of gravity position. The winged wing aircraft according to the present invention is able to carry out the desired flight by adjusting the position of the center of gravity and the aerodynamic center after fully understanding the flight principle of the bird. Actual bird movement is complex and is divided into three movements: flapping, twisting, and folding. The wing of the bird is lifted up front while it is upstroke to generate lift and drag, while the front wing is down during downstroke to generate lift and thrust. While the wing is downstroke, the angle of incidence in the direction of travel is a negative angle of attack, but it is a positive angle of attack for the relative wind, so thrust and lift are simultaneously generated in the wing. This is the case that helps the most. The lift and thrust obtained by the aircraft are obtained by the air force of the flapping wing, so the user can adjust the flight attitude and flight direction of the winged aircraft by moving the center of gravity position of the present invention. have.

Figure 2 shows an embodiment in which the slide device 9 of the winged aircraft according to the present invention and the battery 10 as an accessory are disposed in the device. Therefore, the user can easily move the position of the center of gravity of the aircraft by moving the position of the battery power source of the wing aircraft. In more detail, the slide device is mounted on the bottom of the fuselage 12 in which the motor 11 and the power transmission device are installed so that the user can move the center of gravity (CG) position of the winged aircraft to move the winged aircraft. Change the flight posture of; When a small camera, voice generator, or other device such as a wireless communication device is mounted in the front part of the body (13), which is a bird's beak, or the empty space (14) in the rear part of the body, the slide center is used as the center of gravity changes. It is a device to control the flight and stability by adjusting the position of the center of gravity of the winged aircraft.

The center of gravity position of the winged aircraft must be in front of the aerodynamic center position to ensure stable flight. Therefore, even if the luggage is mounted behind the existing aircraft aerodynamic center position, the center of gravity position should be able to be adjusted to the front of the aerodynamic center position. In this case, the distance from the center of gravity position to the aerodynamic center position is called a static margin, and the center of gravity can be controlled by changing the position of the center of gravity within this distance. Wing aircraft according to the present invention, if the center of gravity position changes due to the payload center of gravity of the wing aircraft using a slide device containing a weight or accessories such as batteries, voice generators, wireless devices or any object By adjusting, you can improve stability and control the flight attitude and direction. If you fly with the center of gravity in front of the aerodynamic center, but move the object installed in the slide device to the front of the fuselage, the winged aircraft will be leaned to the front to make a lot of forward flight forward. If the object is moved to the rear of the fuselage, the winged aircraft is leaned forward, and ascending upwards is much. Of course, in order to adjust the flight attitude using the center of gravity during flight can be equipped with an automated slide device that can be remotely controlled or automatically adjust the flight attitude. Conventional wing aircrafts use a single parameter, the tail wing, to control the steering, but the wing aircraft according to the present invention have two parameters: the center of gravity and the tail wing (15). Since it is controlled by, the difficulty is increased to induce interest to the user. In addition, the present invention is different from the attitude and direction of flight according to the positional relationship between the center of gravity and aerodynamic center, so that you can produce a variety of flight to understand the principle of flight can be used as a parish to understand the principle of flight of winged aircraft. Flight test to adjust the center of gravity of the winged aircraft according to the present invention is to be performed indoors. The user loads luggage on the fuselage of the winged aircraft, and then changes the center of gravity position of the aircraft while calibrating the aerodynamic center and center of gravity so that they can fly through the flight test indoors. Know the flight posture and direction of flight according to the center of gravity. As described above, in order to check and correct the direction of movement of the aircraft in the state of flapping movement, a method of performing a flight test in a suspended state with a thin thread is easy. At this time, you can check the flight posture and direction by hanging the aircraft in one thin thread, or you can check the flight posture and direction according to the aerodynamic center and the center of gravity by hanging the aircraft on two lines.

The slide device according to the present invention is a technology that can be applied to a wing-based aircraft that is slow in speed and generates wing lift as opposed to a fixed wing aircraft that generates lift only when the speed is high. By adjusting, it was possible to use in parallel with the tail wing. Therefore, it is a toy that can induce interest to the user by increasing the difficulty of the control, and a device that can create various flights through the experience and experience of the bird's flying principle.

Conventional wing aircrafts use a single parameter, the tail wing, to control the steering, but the steering is simple, but the wing aircraft according to the present invention have two parameters: the center of gravity and the tail blades. It can be manipulated to increase the difficulty as well as to interest the user. In addition, this invention can be used as a teaching aid to understand the principle of flight, because the flight principle and direction of flight according to the positional relationship between the center of gravity and aerodynamic center (A.C.) can be wonderful flight. In addition, even if the position of the center of gravity changes with the installation of other devices, by using the slide device to move the center of gravity position to ensure the stability and maneuverability according to the flight. The wing device of the winged aircraft according to the present invention not only allows the user to fully understand the flying principle of flying birds, but also helps the user understand the principles of stability and maneuverability of the ornithopter in the flapping motion. In addition, it is designed to understand the change of flight status and principle according to aerodynamic center and center of gravity position.In addition, the flight path of the winged aircraft according to the present invention is similar to boomerang as well as forward flight. It is possible to draw an ellipse coming back, so it can be used as a toy without a remote control (RC) device.

In this way, the present invention not only improves imagination and inquiry ability, but also improves imagination and inquiry ability by understanding flight principles of not only elementary, middle and high school students but also general people about the stability and maneuverability of wings. It will be a tool that plays a role in raising ideas and expanding the aviation population.
