Description

Ultralight plane using para-wings {A LIGHTWEIGHT FLIGHT UTILIZING PARA BLADE}

The present invention relates to an ultra-light aircraft using para-wings, and more particularly, to a super-light aircraft using para-wings configured to be used for leisure or public transportation by shortening the landing distance and lowering the flight speed.

In general, an aircraft equipped with a propulsion device (engine and propeller) and flying in the air by lift generated by a fixed wing is called an airplane. Among them, an ultralight aircraft is small and light, and mainly sports, communication, practice, pesticide spraying, propaganda advertising, and air taxi. It refers to an unarmed airplane used on the back, and the inside is similar to a car, so anyone who can drive a car can adjust it soon.

Passengers, fuel and emergency equipment, seats of 1 or less, 150kg or less, seats of 2, 225kg or less. The fuel capacity is limited to 19ℓ and 38ℓ, respectively.

In addition, propulsion force must be obtained from the propeller, and flight control method or flight principle equipped with a landing gear as a fixed wing device is almost the same as a general airplane. However, the ultra-lightweight plane is difficult to popularize because it requires a lot of stability as well as adjustability, and the plane in which all the main wings are composed must be lifted to fly with lift (floating force) proportional to the area of the main wing. Because it can lift cargo and people, it is necessary to enlarge wings or increase take-off speed in order to get a large lift, and it is impossible to land in a narrow place because it needs to enlarge wings. There was this.

Meanwhile, on the ground or. Paragliders that take off and fly by using a power source that can cause ridges or headwinds are used to generate lift by using wind and fly in the sky. The paraglider is divided into wing parts, lines, risers and harnesses. The wing of the paraglider consists of upper and lower wings, and partitions are formed at regular intervals between the upper and lower wings, and an air chamber is formed by the partitions. Therefore, a rectangular air inlet is formed from the front of the wing, and a plurality of vents are formed in each partition so that air introduced through the air inlet can also enter the respective air chambers.

At the bottom of the wing, the lines are connected at regular intervals, and the wings are spread by the air flowing into each air chamber of the wing, forming a streamline, so that lift can be generated while flying, acting on the lower wing. The force applied to the lines through the harness and riser by the lift and the weight of the pilot is balanced.

However, if the line is twisted during flight or the operating time of the preliminary parachute is not enough, more than 90% of the passengers will be seriously injured, and the shock-absorbing airbag injecting gas into the harness to prepare for the fall will Since the inside of the harness is filled with the high pressure gas filled inside, the volume of the harness is relatively increased, which makes it difficult to transport and handle the equipment. If there is a gas leakage due to the gas can not be recharged, there was a problem that you need to replace the airbag separately or replace the entire harness.

In addition, when flying using a paraglider, the air flows through the boundary layer of turbulence, ascending and descending air flows, instead of the linear flow due to irregular weather, where the canopy located in the turbulent or airflow boundary layer is lifted. Loss of balance with the force applied to the lines and the paraglider collapses rapidly and rotates or falls, leaving the turbulent or airflow boundary layer, and the collapsed wing collapses by introducing air through an air chamber close to the air inlet. The wings will recover and this time of recovery must be restored within a few seconds. If the wing does not recover within a few seconds, it will crash and cause an accident, and there is a problem of stability, and the existing paraglider and the ultralight plane lacked economic feasibility.

The present invention has been made in order to solve the problems of the conventional ultralight aircraft and paraglider, and can be landed in a small space by the auxiliary function of the paraglider's propulsion force and the paraglider, and can improve stability. The purpose is to provide an ultralight aircraft using a paraglider.

In order to achieve the above object of the present invention, the ultralight plane using the paraglider of the present invention includes a main wing of an ultralight plane consisting of a frame, an upper plate and a lower plate. In the paraglider of the paraglider, the main blade is provided with a through hole formed at regular intervals on the top plate, and a hollow mountain line winding roller in which a line is wound between each pair of small ribs; The upper line connected by the lower line and the connecting ring is characterized by consisting of a paraglider connected to the bottom.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 10, the ultralight plane using the paraglider of the present invention has front and rear ends of each of the large ribs 1a arranged at regular intervals on the front and rear supports 1d and 1e. A pair of small ribs 1c are fixed to each other, and a pair of small ribs 1c are arranged at one side of each of the large ribs 1a or at one side of the small ribs 1b, and each of the large ribs 1a is disposed. And a pair of insertion holes 1a ', 1b', and 1c 'are formed at the bottom of the small ribs 1b and 1c, and each of the large ribs 1a and the small ribs 1b and 1c is formed. A pair of inner supporters 1f are inserted into and inserted into the insertion holes 1a ', 1b' and 1c ', respectively, and an upper plate and a lower plate are provided at upper and lower portions of the frame 1, respectively. Main wings of the combined ultralight airplanes;

The front part is open and the inside is formed in the longitudinal direction by the partition 2a, and the air inflow chamber 2b is formed by the said partition 2a, respectively, and each partition 2a has a vent hole In the paraglider 2 of the paraglider in which the 2a 'are formed at regular intervals, and the line 4 is connected to the bottom surface,

Through-holes 5a are formed at regular intervals to allow the lines 4 to penetrate through the top plate 5, and the hollow line windings in which the lines 4 are wound between the small ribs 1c. A main blade A on which the roller 6 is installed;

The line 4 wound around the hollow acid line winding roller 6 of the main wing A consists of a paraglider 2 connected to the bottom surface,

The hollow acid line winding roller 6 has bolts 6a inserted into the shaft holes 1c "formed in both small ribs 1c, respectively, inserted into the hollow portion of the hollow acid line winding roller 6, and the hollow line winding The spring 6b is provided between the side part of the roller 6 and the small rib 1c of one side,

The shaft hole 1c "is preferably formed between the small ribs 1c on both sides and between the inner supporters 1f on both sides. In the drawing, reference numeral 6a 'denotes a nut, 7 an adjustment chamber, 8 an engine, 9 is a horizontal tail wing and 10 is a vertical tail wing.

The ultralight plane using the paraglider of the present invention configured as described above is used as follows.

In the case of taking off the ultralight airplane using the parallax according to the present invention, if the propeller is rotated by driving the engine after the occupant is in the passenger seat, the ultralight airplane of the present invention obtains the driving force by the propulsion force. .

As such, while the paraglider 2 is slid along the runway in a state where a constant propulsion force is generated in the ultra-lightweight plane, the paraglider 2 is unfolded by the sliding and aerodynamic force of the ultra-lightweight plane, whereby the para-wing 2 is lifted off and is lifted off. The para wings 2 fly in a fully extended state.

Here, all the main wing plane is formed to fly with a lift proportional to the area of the main wing (A), because the lift to increase the cargo and people can lift the main wing (A) to obtain a large lift In the present invention, by using a very light material and a flexible para-wing (2) as an auxiliary wing, when the slide speed is 20km / h or more during takeoff, it is installed in the main wing (A). Since the line 4 wound around the hollow line winding roller 6 is released, the paraglider 2 is formed and receives a large lift, so that it can take off before the speed of 30 km / h.

Therefore, even when the run distance is short, the takeoff of the ultralight airplane using the paraglider of the present invention is possible, so it is possible to operate with only a small airfield and the length of the main blade can be very short, so the low speed of flight speed It becomes possible.

In other words, the force required to float the plane is structurally proportional to the size of the main wing (A), so in order to float only one person, the length of the main wing should be large, about 10m, as in the present invention of the main wing (A) Lifting force is increased by installing large para-wings (2) on the top, which are made of synthetic fibers weighing a few tenths of the weight of main blade (A), and having the function of generating much higher lift than main blade (A). The length of the main wing (A) can be reduced to less than 6-7m.

In addition, by increasing the length of the para-wing (2) and the main wing (A) can be obtained more stability, and the length of the fuselage can be reduced, so that a small engine can be used, the landing distance is also shortened to less than 20m .

In addition, since the para-wing 2 is protected by the main wing A, the para-wing 2 is prevented from collapsing due to a gust or other irregular weather. Thus, the para-wing of the present invention is used rather than a paraglider or an ultralight plane. The used ultralight aircraft can fly in a high safety state, the engine horsepower can be reduced, and the plane can be miniaturized.

On the other hand, if you want to land the ultra-light aircraft using the para-wing of the present invention by pulling the lift key in the same way as a normal airplane to reduce the thrust of the engine than the drag force is gradually lowered as the speed is lowered by the lift key After landing at the landing point of the runway, the vehicle decelerates and stops while running the runway. At this time, the thrust can be made much smaller than the drag force by the para-wings (2). , The loosened line 4 connected to the paraglider 2 has the line 4 wound around the hollow line winding roller 6 as the hollow line winding roller 6 is rotated by the elasticity of the spring 6b. You lose.

As described above, since the present invention combines a paraglider and a light aircraft, the present invention can safely fly at a low speed and eliminate the risk of falling because it can prevent the breakdown of the irregular paraglider 2 of the conventional paraglider. This makes it possible to use a small horsepower engine by making adjustments low and increasing lift. In addition, the airplane can be manufactured in a small size, which reduces production costs, that is, the price is low, thereby facilitating expansion. Since the stability is high without any difficulty in adjusting the plane, anyone can easily learn airplane technique, and the ripple effect of leisure sports activities is greatly increased. In particular, it is possible to solve the pollution problem caused by the increase in traffic volume and the congestion of roads due to the industrialization of the city and the increase of population, and it is possible to use it as a new short-distance public transportation system if only a small runway space is needed. Gliding distance is more than twice as long as the ultralight is effective.
