As a multi-purpose learning material and science toy that combines the principles of general science with exciting play, the water rocket launcher recycles synthetic resin recycled beverage bottles, etc., and attaches a water rocket made of a beverage bottle to a water rocket launcher, And the pressure inside the water rocket is raised to automatically fire at the set pressure. The principle of this water rocket is Newton's third law of motion, which states that "when a force is applied between two objects, the forces between the objects are the same, the directions are opposite, and they act on the same straight line" The compressed air is similar to the principle of a real rocket that launches while blowing gas from the principle surface, which acts like a spring, causing the propelling force of water to fly in the direction opposite to the direction in which the water is sprayed. Many teachers and students are interested in water rockets, and the use of water rockets is becoming common, and water rocket lectures are being actively conducted in the invention classroom and the gifted classroom.

The above-described learning rocket launcher is useful as a learning material for observation of the launching principle by the physical motion law as well as the educational effect of the recycling of the waste product using the disposable beverage bottle, thereby contributing to the improvement of the inquiry power by promoting the interest of the children The bar is big, and it is possible to realize the learning effect that helps the understanding by not only learning by memorizing with the eyes but also by experiencing directly.

The conventional water rocket launching apparatus of the present invention constitutes a warhead composed of a container body made by recycling a synthetic beverage bottle and the like, and a water rocket of a known shape having a plurality of blades coupled to the lower part of the warhead, A launching device for supporting the launching device in such a manner that it can be supported by a clamping method and at the same time allowing the compressed air to be blown by the force of ejecting the water by the action of the compressed air and a pedestal for stably supporting the launching device on the floor, An angle and direction control device for controlling the launch angle and launch direction of the water rocket, an air injection device such as a foot pump, a remote launch handle, and a water rocket guide rail.

However, unlike a conventional rocket launcher, which uses fuel as its combustion power, the compressed air acts as a spring to act as a propelling force, which allows precise and stable firing. Even if development of an easy device is required, it is troublesome and troublesome due to its configuration and operation, and is liable to malfunction due to foreign substances. Moreover, even if water rocket snout is closed with one hand and water rocket is mounted upside down or mounted, It is difficult to precisely target a target such as a firing distance, it is difficult to inject a proper amount of compressed air of a desired pressure into a water rocket, and it is difficult to install and carry and store .

The pedestal 100 is installed above the angle and direction adjusting means 130 to store and compress the air supplied to the rocket, (200) for emitting a light beam.

Since the configuration of the launching means 200 is the same as that shown in Figs. 1 to 3, a detailed description thereof will be omitted. However, since the configuration of the pedestal 100 shown in Figs. 1 to 3 is different, only the configuration will be described.

The tripod 120 includes a support 121, a center rod 122, a rod control lever 123, a height / direction control rod 124, a coupling member 124-1, a plate member 126 And a connecting member 128, as shown in Fig.

A user holds the handle 126 installed on the plate member 126 with the height of the height / direction adjusting rod 124 adjusted and rotates to the left or right to set the launch direction of the rocket.

The aim of the rocket is to adjust the length of the antenna 244 installed in the distributor 210, and then to set the launch direction of the rocket so that the antenna 244, the target, and the rocket are located on the same line.

In this case, the launch angle of the rocket is determined by holding the knob 127 and moving the hinge 124-2 along the axis of the plate member 126) in the front-rear direction (front-rear direction in a state where the user holds the knob) to adjust the firing angle. At this time, the firing angle is adjusted while checking the angle scale (not marked) displayed on one side of the hinge 124-2.

It is determined whether the pressure of the air stored in the air tank 250 has reached an appropriate pressure in a state in which the launch direction and the angle of fire of the rocket are adjusted and if the pressure of the air tank 250 reaches a proper pressure, Stop and determine the launch time of the rocket.

When the button 231-1 of the switch 231 provided at one side of the connecting hose 230 is pressed with the direction of the rocket, the angle of fire and the pressure of the air tank 250 being set, The remaining air is discharged to the button 231-1 and the exhaust valve 240 is operated to supply the compressed air of the air tank 250 to the launch rod 270 provided with the rocket.

The compressed air in the air tank 250 is applied to the exhaust valve 240 and the air applied to the exhaust valve 240 is supplied to the launch rod 270 to fire the rocket.

In the case where air is supplied to the launch rod 270, the inflow hole (not shown) of the exhaust valve 240, that is, the inflow hole toward the air inflow side is closed, and only the discharge hole on the side where the launch rod 270 is installed Because it is open, the rocket is fired by air.

Since the air is not stored in the air tank and the air is directly supplied to the rocket, the user can not clearly grasp when the rocket is fired, so that the user does not understand the principle of launching the rocket. I did not. However, since the user directly controls the launch of the rocket, the present invention can clearly confirm the state of the launch of the rocket, so that it is possible to clearly understand the principle of launching the rocket.

In other words, by selecting the launching point of the rocket, the user can clearly see the launching moment of the rocket and the principle of launching the rocket. There is an advantage to understand easily.

In addition, the present invention makes it possible to easily understand the principle of science by making it possible to confirm the state that the compressed air acts like a spring using the Newton's action and reaction law.
