Detailed description of the invention
The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
Drones are widely in use for various works to facilitate services and sales. For fire, safety and rescue also it is being used only to supply goods and rescue equipments to the victim. First aid is also being provided through drones but to have launcher of fire extinguishing media directly over fires to act as first responder to fires is being used nowhere. This launching system of fireballs over fires with accuracy by firemen from ground will become revolutionary in the field of firefighting as air route is always shorter than the road route.So it is basically a multipurpose system having capability of fighting fire simultaneously with providing assistance in rescue operations
Another novelty is the versatility of this drone as it can perform multiple tasks i.e, surveillance before and after incident and quick response in case of emergency. Locating victims through thermal imaging camera is yet another novelty of this product.
Refereeing now to figures 1 to 3, itshowsdifferent views of a firefighting drone system (100) in accordance with the present invention.

1. Drone:
The drone itself is made from some of the top materials available on the market, 3K carbon fibre plates and tubes, aluminium CNC parts which are anodized, plus thick and lightweight carbon fibre plates at the base of each
motor. The drone measures 1.2 meters , or 3.9 feet from motor to

motor.Advanced flight controller system, the operator can program waypoints and flight plans into the drone before takeoff. The flight controller features manual flying modes, stabilize mode, and return to home mode in addition to the autonomous mode. The drone can either be piloted with the included controller when flying manually or via a laptop or tablet utilizing the free Mission Planner software when flying autonomously.lt also features a failsafe function and will return to home automatically if it loses signal or if the battery becomes weak.Carry a payload up to 8kg.Octo-copter design frame promotes stability and precision flight control.Electronically controlled folding landing gear to protect landing.Capable of achieving range distance of 2 miles.Achieve flight time of up to 20 minutes on a single charge.
2. Fireball launcher:
The fireball launcher is an advanced pneumatic remotely operated launcher that is consisted of piston chamber that under high pressure strikes the fireball to laugh out of barrel. All the parts are constructed with light weight materials. These parts are as follows:
a) Pressurized air cylinder:
Constructed from light weight aluminium alloy inner lining wrapped with carbon fiber above this is a glass fiber layer and final coating of resin layer. This cylinder can provide a high pressure air up to 300bar. This will be very light weight not more than 3kg. The discharge port is an air release valve leading towards the diaphragm valve.

b) Electronic Diaphragm valve:
A diaphragm valve is a spring loaded valve that doesn't allow upstream to release pressurized fluid unless spring is released manually or electronically. Here electronic operation is preferred for remote operation.
c) Piston chamber:
After the diaphragm valve, this pressurised line reaches to a wooden piston. The compressed air pushes the piston from upstream chamber as it is highly pressurised. The downstream chamber is low pressure chamber and hence piston moves forward with a high momentum.Front part of the wooden piston is a round hemisphere made of gasket rubber/wood.This hemisphere has same diameter as the barrel diameter. Movement of the piston strikes the fireball pushing it out of the barrel with a huge force that makes it launch to a considerable distance.
d) Air reservoir tank:
Once the piston is pushed by the upstream pressurised chamber, the downstream chamber gets pressurised due the piston movement. This pressurised air moves into air reservoir tank creating positive pressure but now the up-stream chamber depressurises due to closing of diaphragm valve. Hence this air reservoir with positive pressure pushes the piston back to its normal position. Hence this air reservoir tank is used to move the piston back every time when piston is operated.
e) Fire ball cartridge:
This is a circular tube loaded with 4 fireballs which are pushed forward by a spring that provides sufficient force to supply fireballs into the. barrel for shooting. This barrel is constructed with lightweight yet strong material.
f) Shooting Barrel:
Barrel is connected to piston chamber where the piston will strike the fireball. This barrel has diameter equal to the diameter of fireball. Barrel

also provides better accuracy for shooting fireballs to the required area under fire. Barrel is constructed of a lightweight yet a very strong material.
g) Thermal imaging camera:
Thermal imaging camera is mounted just over the barrel to provide with better visibility of fire and temperatures of the area under fire. Victim location is yet another use of thermal imaging camera which is first priority. Camera will also be used for targeting the fireball at an accurate position.
As soon as the fire occurs, the fire brigade has to take turnout and reach at the fire site as quick as possible. This drone will reduce this time and leave the fire brigade as it is readily placed for turnout. As the drone will be in the air, it will become very easy to locate fire site from the sky. The drone will then reach quickly at the site locating the nature and of fire and the substance burning. Victims will be easily located by the use of thermal imaging camera, also the fire intensity will be measured by the camera that will make easy for the shooting of the fireball at right locations. The fireball launcher will be electronically launched remotely from control room or anywhere within the radius of 2 miles. Once the cartridge with 4 fire-balls is finished, fire brigade reaching the site will have extra fireball cartridges and extra set of quick removable batteries. This will allow fire fighters for extended time to response and firefighting. As the fire is now controlled at its incipient stage, it is now easy for the fire-fighters for winding up and post-fire investigation processes.
A Drone is a very good carrier for various equipments and therefore, it is also useful for firefighting operations. Hence, introduction of the Launcher system, that allows the fireballs to launch with accuracy over fire. These fireballs are filled with DCP powder which can control all classes of fire. Thermal imaging camera allowing the firemen to locate victim and also intensity of fire, same camera is also used to launch fireballs with accuracy.

With this system installed over a drone, will become revolutionary in firefighting at various occupancies when the fire is at its incipient stage.
