Description

Rudder for a tail wing of model plane {Rudder for a tail wing of model plane}

The present invention relates to the direction key device of a model airplane tail wing to increase the gliding time of the model airplane, and more specifically, to allow the part of the vertical wing of the tail wing of the model airplane to be rotated, so It is related to the direction key device of the model wing tail wing that amplifies the sense of pleasure because it will turn in the air for a long time.

In general, a model airplane, which is a type of play equipment that satisfies the desire to fly, is equipped with a non-powered model airplane consisting of a glider flying in the air or a rubber power driven by rubber power, and a motor and engine. It can be classified as a powered model airplane that can be adjusted wirelessly.

The present invention is applied to the dual non-powered model airplane, and will be described below with particular emphasis on rubber power units.

As shown in FIG. 1, the rubber power unit is fixed with a fore wing holder 2 'and a tail wing holder 3' to the fuselage 1, and a fore wing 2 and a tail to each of the holders 2 'and 3'. The wing 3 is fixed, and the propeller 6 and the landing wheel 9 are coupled to the front end of the fuselage 1, and are provided at the lower end of the shaft 6 'and the tail wing holder 3' of the propeller. The power rubber line 7 is connected between the hooks 8.

Rubber-powered model airplanes configured as described above have a propeller coupled to the front of the fuselage in either direction (for example, the direction of rotation is determined by the angle of propeller blade rotation, which is usually clockwise). As the rotational force is transmitted to the connected rubber power line, it rotates in the same direction as the shaft.

At this time, since the hook is connected to the other side of the rubber power cord provided on the tail wing side is fixed, the rubber band is twisted while receiving the rotational force around the hook is a rubber cord that was loose, and the length is contracted.

In addition, the twist is to amplify the elastic force while twisting the rubber power line through the rotation of the propeller until the range of the elastic limit of the rubber power line does not deviate.

In order to prevent the propeller from rotating by the elastic amplified rubber power cord, the propeller is held by one hand and the fuselage is held by the other hand and then blown into the air. Conversely, the propellers will rotate.

At this time, the model propeller becomes more emergency in the air by the rotating propeller, and the model plane flying in a straight line decreases the speed due to the resistance of the wind, and feels the playfulness during the landing time while drawing the parabolic shape as a whole. will be.

However, since the wind and airflow are not constant at all times, when the strong wind blows, the propellers must fly low even when the propeller rotates, so the play time is short and the playfulness is easily lost. There is a risk that the model plane will be lost due to airflow on the tail wing.

In addition, because the wind does not catch the landing point to gliding with the parabola, the model airplane has to go back to find the landing after completing the landing work, and landed in a shape that slides down from the top, there is a risk that the model airplane is easily damaged. have.

In particular, in a model airplane flying contest, many studies are being conducted to increase the gliding time by making a lot of modifications within the scope of the regulations, which are scored according to the gliding time of the model airplane.

The purpose of the present invention is to devise to solve the above problems, and to allow the model aircraft to turn into the air in the court, it can make the turn and increase the glide time and increase the pleasure, but also easily swept in the strong wind. It provides a model airplane that prevents the model airplane from being lost and descends while turning, minimizing the impact on the model airplane and minimizing the risk of damage.

The present invention for achieving the above problems, the front wing fixture and the tail wing guide is fixed to the fuselage, the front wing and the vertical wing and the horizontal wing is connected to each of the fixture is fixed, the propeller and the front end of the fuselage In the rubber-powered model airplane coupled to the landing wheel, the power cord is connected between the shaft of the propeller and the hook located at the bottom of the tail wing fixture; A direction key to enable rotation on either side of the vertical wing of the tail wing; A connecting line connecting the hook and the direction key so that the direction key of the vertical blade can be rotated without being affected by the wind; An elastic cord made of an elastic body which rotates a direction key in association with the operation of the connecting cord; A pedestal formed on one side between the vertical wing and the direction key so that only a limited section can be rotated when the direction key of the vertical wing is rotated; It is characterized in that it has a surface formed at a predetermined angle on the back side of the pedestal, consisting of a variable support detachable so that the angle can be modified.

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

2 is an overall perspective view of a model airplane according to the present invention, the rubber power model airplane is fixed to the front wing fixture (2 ') and tail wing holder (3') to the fuselage (1), each holder (2 ') (3 ') The front wing (2) and the tail wing (3), the vertical wing (4) and the horizontal wing (5) are coupled, respectively, and the propeller (6) and landing wheel (9) is coupled to the front end of the body (1) , The power rubber line 7 is connected between the shaft 6 'of the propeller 6 and the hook 8 located at the bottom of the tail wing holder 3'.

And, the operation sequence is the power rubber line 7 provided between the propeller shaft 6 'and the hook 8 by artificially rotating the propeller 6 provided at the front end of the body 1 as in the conventional description above. ) Is twisted around the hook (8), which is fixed at one end and is subjected to elastic force.

At this time, as shown in Figure 3 and 4, a direction key (rudder) 12 is formed on one side of the vertical wing (4) of the tail wing (3) so as to be rotated, the direction key (12) It is connected to the hook (8) with a connecting line (14), one side is fixed to the vertical wing (4), the other side is provided to support the direction key 12 is the direction key 12 by the connecting line (14) The pedestal 18 is formed to prevent the bending indefinitely.

In addition, the back of the vertical wing (4) formed with the connecting line 14 and the pedestal (18) is formed between the direction key 12 and the fixing base (3 ') of the tail wing (3') to face the connecting line (14) 16 is connected, one side is fixed to the vertical wing (4) so that the direction key 12 can be bent at a certain angle by the elastic cord 16, the other side has a variable pedestal having a surface forming a certain angle ( 19) is provided to be removable.

At this time, since the power rubber line 7 provided between the shaft 6 'and the hook 8 of the propeller 6 is reduced in length while having elastic force by twisting, the tail wing 3 of the fixing stand 3' The hook (8) provided at the bottom is bent to pull the connecting line (14) connected to one side, and to pull the direction key (12) connected to the other side of the connecting line 14, the vertical wing (4) and the direction key (12) By the pedestal 18 provided on one side of the), the direction key can be maintained in an unbent state.

Then, when the model airplane is blown into the air while the power cord 7 is not released, the rubber power cord 7 having elastic force is released while rotating the propeller 6 provided at the tip of the fuselage 1. The propulsion generated there makes the model plane more emergency.

On the other hand, the model airplane that was flying by the propulsion force loses the rotational force transmitted to the propeller 6 while the kink of the rubber power line 7 is released, and the model airplane starts the gliding on the rising air.

And, as shown in FIG. 5, the hook 8 pulled by the rubber power cord 7 has a recovery force as the twist is released and returns to its original position, and the connecting cord 14 formed between the hook 8 and the direction key 12 is provided. It is to reduce the tension, the elastic force is applied to the elastic cord 16 is an elastic body coupled between the tail wing fixture (3 ') and the direction key 12 so as to face the rear surface of the direction key (12) vertical wing (4) The direction key 12 is rotated, and at this time, one side of the vertical wing 4 is fixed and constrained by a variable pedestal 19 having a surface formed at an angle to the other side, so that the direction key 12 is a vertical wing 4 ) And bend at a certain angle.

Therefore, the model airplane on the ascending air is to wind the wind by the angle of inclination of the direction key 12 to bend the direction of travel of the fuselage 1, so that the model airplane is to turn in the air as a whole.

Therefore, not only does the model plane take longer time to glide in the air, but it also falls while turning, so that the impact on the model plane can be alleviated by landing, thereby protecting the model plane and eliminating the risk of being lost by strong airflow. will be.

In particular, competitions in which the winners are decided according to the gliding time such as a model airplane flying competition may have more favorable conditions.

As described above, the present invention not only amplified the pleasure obtained by increasing the gliding time of the model plane by allowing the fuselage to turn when the model plane gliding in the air, but also eliminated the risk of losing the model plane by being swept by strong wind. In addition, it is a useful design that reduces the risk of damage by mitigating the impact on the model plane when landing.
