FxUAV Technologies: The Fire Fighting Wing

Objectives
  • To build an Unmanned Aerial Vehicle (UAV), that reaches the spot of report/incidence in the least time possible for initial severity analysis.
  • To ensure proper data logging from the on board avionics for assistance in decision making process.
  • To develop a suitable payload and payload deployment system so as to mitigate the fire hazard, in case of incidents of high severity.
  • To create launching and ground control descent systems suitable for getting the UAV on or off flight.
National Scenario
  • India faces a steep deficit of fire stations. Where, as per the area to be covered, 8559 fire stations are needed, currently India has 2987 fire stations, in all, marking the deficiency at 65%.
  • The Forest Survey India (FSI), reported 22,882 forest fire spots in Odisha alone, the highest in India in 2018. These incidents escalate during summers and throughout the year in perpetually dry areas.
  • Testimonies taken directly from fire station officials in Bhubaneswar and Sambalpur, state that in several situations, additional brigades were sent after the first dispatch reached the spot.
  • Currently, there are several Startups dealing with general purpose UAVs, but none of them deal with firefighting as a specific exclusive purpose.
Novelty
  • The usage of Fixed Wing UAVs: Our usage of fixed wing UAVs is based on the idea of getting to the fire spots as fast as possible. None of the companies in the Indian Market use Fixed Wing UAVs specific to the purpose of fire-fighting.
  • Deployment of Payload: Our UAVs have a payload deployment system incorporated within itself. This is to mitigate the fires with very high severity and expansion risk.
  • Versatility of Payload: The payloads are customized as per the fire source. For class B fires - sourced from petroleum and other liquid explosives, aerosol or foam based payloads are used. For class A fires - solid powdered extinguishing agents as Monoammonium phosphate are used.
  • Hybrid Control of UAVs: The UAVs can be manually controlled by trained fire station officials front the ground station. In any case of contact disruption, the UAV has the capability of switching to Auto Pilot Mode and navigt3 based on the incorporated flight path.
DESIGN ASPECT
  • The UAV is a fixed wing tail type UAV.
  • The tail is below the wing axis (high wing).
  • The Fuselage is of airfoil shape.
  • The wing is of NACA 2412 design as it has a greater weight balancing ability.
  • The wing is straight leading and trailing edge type.
  • There are two rotor attached on the wings (front facing).
  • The UAV has two aileron, two flaps, two elevators connected with servos to show simulated movement.
  • The Fuselage will have Lithium ion battery made from combinations of 2600mah li-ion battery.
  • For constant connection with the ground station, 2.4Ghz tx and rx are used.
  • Bungee launcher will be used for launching.
  • The tail will have a hook for sky hook landing system.
  • Parachute landing is considered as a recovery system.
  • RTL will remain on while going for a flight.
PAYLOAD DEPLOYMENT
  • The payload is made up of mono ammonium phosphate.
  • Gun powder is tightly packed inside the core of the chemical.
  • The drop payload has a design of an egg like structure.
  • The later model has a mini missile launching technique which is designed keeping building fire in consideration.
  • The missile will be a low cost missile placed inside the body of the UAV.
