Abstract

PURPOSE:To reduce the generation of noise and vibration during take-off and landing by utilizing a lift generating device for an aircraft and to shorten a runway by artificially generating an air flow to generate a lift. CONSTITUTION:Air is fed to the whole upper surface of a wing 1 so that a flow A of air is generated, an atmospheric pressure in a vertical direction on the upper side of the wing 1 is reduced, and a lift F is generated by means of a difference in an atmospheric pressure between upper and lower parts. In this case, air flows out through an air outflow port 4 after the flow of it through an outflow port slide rail 2 and an air outflow amount regulating plate 3. This structure causes the artificial generation of an air flow on the wing 1 and positively generates a lift. Thus, by mounting a lift generating device on, for example, an aircraft, safe flight can take place and consumption fuel is saved. Further, the device is served as a measure to counter the generation of noise and vibration.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that generates lift by artificially creating airflow on a wing.

1. Description of Lift Generation Device As shown in Figure 1, the lift generation device sends wind so that air flows over the entire surface of the true upper side, lowers the atmospheric pressure in the vertical direction of the true upper side, and increases the air pressure above and below it. This is a device that generates lift using a pressure difference.

2. Aircraft equipped with a lift generating device Conventional airplanes advance the aircraft at a certain speed against still air, creating true airflow as shown in Figure 2, and creating a difference in airflow above and below the wing. This creates a pressure difference, which generates lift. Therefore, lift cannot be generated unless the aircraft speed is increased, requiring a long runway, and the high speeds of takeoff and landing made maneuvering difficult and dangerous. In addition, noise and vibration during takeoff and landing were also a problem.

There are also short-range takeoff and landing aircraft that generate lift using a mechanism similar to the present invention, but because the flight engine and lift generator are both used, lift can only be generated on a portion of the main wing. Ta.

Conventional vertical take-off and landing aircraft use propulsion to lift vertically, which is inefficient in terms of energy, and requires advanced technology to maintain balance.

(a) When the lift generating device of the present invention is attached to an airplane as shown in FIG. 3 and the device is activated, the airplane will rise as soon as it taxis, as shown in FIG. 4. When a certain altitude is reached, the jet engine is injected, the lift generator is stopped, and normal flight begins.During landing, the lift generator is activated to generate lift, then the jet engine is stopped and the speed is increased. and land as shown in Figure 4. Therefore, noise and vibration during takeoff and landing are low, and the runway can be shortened. In addition, the aircraft takes off and lands at low speeds, making it easy to maneuver and safe.

(a) Figure 5 shows a vertical takeoff and landing aircraft with circular wings and a lift generator. When the device is activated, lift is generated on the wings, causing them to rise vertically. Since it lifts up using lift, it is energy efficient, and it is easy to maintain balance because the center of gravity is lowered.Furthermore, even if the device fails, the wings will replace the falling weight, so it descends at a low speed while maintaining balance. ,
If you reverse thrust just before crashing, you can land safely.

In this way, adding a lift generating device to an aircraft
It allows for safe navigation, saves fuel consumption, and also acts as a countermeasure against noise and vibration. It should be noted that various other methods for generating airflow based on the shape of the wing can be considered.

3. When moving a transporting machine equipped with a lift generating device, it is difficult to move vertically, but it is easy to move horizontally. Therefore, the transporting machine has a lift generating device as shown in Figure 6. Once the device is attached, objects can be easily transported.

The small lift generator can also be used to transport small items.

4. Other applications Humans can also be made to fly by attaching lift generating devices to their bodies. It can also be applied to toys and models.

Note that even underwater, the lift generating device can generate water flow to generate lift.

As mentioned above, the lift generating device can be widely applied.
