Description

Safe artificial rocket with parachute throwing device

technical field

The invention relates to a safe special-purpose lightning-inducing rocket for artificially inducing lightning.

Background technique

Artificially induced lightning (also known as artificially triggered lightning, artificially induced lightning, and artificially induced lightning) is a new technology developed in recent decades. It refers to the use of certain equipment and devices (generally by A small rocket carries a thin steel wire several hundred meters long and 0.2 millimeters in diameter that is launched into a thunderstorm cloud) to trigger lightning.

In the technology of artificial lightning induction, the lightning induction rocket is the main tool for lightning induction. According to the principle of artificial lightning induction, the lightning induction rocket is required to have the following technical indicators:

V ₀ <15m/s

Vmax＜190m/s

H＝800-1000m

The practice of artificially inducing lightning shows that: the speed of the lightning-inducing rocket is the key to the success of artificially inducing lightning. If the speed is too fast, the metal wire will be broken, and if the speed is too slow, the lightning will not succeed. General anti-hail and rain rockets are characterized by high speed and high range, and this speed and height are not applicable to artificial lightning; secondly, after the lightning-induced rocket rises to the highest point, the rocket remnant will move extremely fast. Falling at a high speed will cause damage to ground personnel, livestock and buildings, and there are hidden dangers in safety. Therefore, it is necessary to design a safe special-purpose lightning-induced rocket suitable for artificially induced lightning.

Contents of the invention

In view of the above-mentioned problems, the object of the present invention is to provide a safe special rocket for artificial lightning with a parachute throwing device suitable for artificial lightning. Utilize its structural features to successfully induce lightning, and make it throw out a parachute during the landing process, so that the rocket can land slowly and safely.

The purpose of the present invention is to realize through the following technical solutions:

The utility model relates to a safe artificial lightning special rocket with a parachute throwing device, which mainly consists of three parts: an arrowhead, a rocket body and an empennage. There are rocket motors, engine ignition electric squibs in the rocket body, parachutes, parachute throwing powder and delay devices in the arrowheads, spools are installed at the lower part of the tail, and the engine ignition electric squib wires drawn from the rocket body and the throwing tubes drawn from the arrows Umbrella powder ignition wires are connected in parallel to form rocket launch ignition wires. A spool of metal wire is installed at the bottom of the rocket tail. There is a card slot in the spool, and the lower part of the tail is embedded in the groove, so that the spool is fixed.

The rocket engine is a double-lead-2 tubular double-base drug, and the length of the drug column is Φ45×Φ8×175mm.

The rocket trajectory parameters are: V ₀ ≤15m/s, Vmax<190m/s, H=800-1000m, and the rocket speed range is 120m/s<V _100-500m <190m/s.

Another object of the present invention is to provide a special rocket launcher suitable for artificial lightning.

The rocket launcher is composed of two aluminum alloy grooves to form the guide rail of the rocket. There is a bracket for fixing the guide rail under the guide rail. Place the pneumatic igniter on the lower part of the guide rail, connect the igniter power output lead to the rocket ignition lead, and connect the gas pipe for controlling the pneumatic switch to the launch console 80 meters away.

Advantage of the present invention and the beneficial effect that produce are:

1. The present invention designs rocket ballistic parameter as muzzle velocity V _0≤15m /s, maximum velocity Vmax＜190m/s, velocity range requirement is 120m/s＜V _100-500m ＜190m/s, can guarantee that lead wire is not caused by rocket like this The speed is too fast and it is pulled off, and the speed is too slow to cause the failure of lightning.

2. The present invention adopts the device that a parachute is housed at the arrowhead, and the rocket remnant falls slowly due to the traction of the parachute during the landing process, thereby greatly reducing the possible damage caused by the rocket remnant to ground personnel, livestock and buildings. injuries, ensuring the safety of ground personnel.

3. The present invention adopts engine ignition and parachute charge ignition to start simultaneously, but the method for delayed ignition of parachute charge makes the parachute throw out when the rocket rises to the highest point, ensuring the height of the rocket rise.

4. The present invention has a spool in the lower part of the empennage, and adopts the method of setting out the wire in the air to lead the lightning, which is better than the effect of pulling the wire on the ground, and can greatly improve the success rate of the lightning.

5. The rocket engine is a double-lead-2 tubular double-base drug. The drug is a safe gunpowder, which can only be ignited under high temperature and high pressure conditions, so it is relatively safe to use.

6. The upper part of the rocket rack is open, so that the rocket and the spool can be released smoothly.

There are parachute 6, parachute ignition powder and delay device 7 inside the arrow; spool 8, engine ignition electric detonator lead 9 and parachute charge ignition lead 10 are installed on the lower part of the tail, and the two wires are connected in parallel to form a rocket launch ignition Wire 11.

The rocket is placed on the rocket launcher (seeing accompanying drawing 2), and the launcher is made up of the guide rail 12 of rocket by two wide 56 millimeters long 2 meters alloy groove aluminum, there is the support 13 of fixing guide rail below, and the rocket support top is open so that the rocket and bobbin 8 can be released smoothly. Pneumatic igniter 14 is placed on the bottom of guide rail, igniter power supply output wire 15 is connected with rocket ignition wire 11, and the gas pipe 16 of control pneumatic switch is connected to the launching console (seeing Chinese patent 200510041659.2) beyond 80 meters, when thunderstorm cloud arrives When the launch point is above the sky, and the electric field strength on the ground reaches the lightning trigger index, the console switch is connected to the gas source, and the high-pressure gas is output to reach the pneumatic igniter through the gas pipe. The rocket motor 4, the rocket flies out from the launcher along the guide rail 12 of the rocket. When the rocket flew upwards, the metal wire on the spool 8 would be continuously released downwards. When the rocket reached the maximum height (800-1000m), the delay device 7 ignited the parachute, and the arrow 1 was separated from the rocket body 2. The parachute 6 installed on the head of the rocket is thrown out from the arrow, dragging the arrow 1 and the rocket remnant to land slowly on the ground, completing the whole process of rocket launch.
