Helicopter drone for fighting forest fires
Thursday 9 Apr 2020
Created by Chinese manufacturer QilingUAV, the JC260 can be equipped with two of the company's retardant-filled "fire extinguishing bombs." Dropped separately or in unison, each of the bombs the company claims can cover a flaming forest area of 50 cubic metres.
Lift is provided by two sets of counter-rotating rotor blades, measuring 3.6 m in diameter. These are powered by two 34-hp water-cooled gasoline engines, taking the aircraft to a claimed cruising speed of 100 km/h. One tank of gas should be good for a flight time of three to four hours.
A ground-based operator remotely pilots the drone in real time, based on output from its onboard cameras. A simple one-click system on the remote is used to drop the bombs. The copter measures 2.8 m in length, and tips the scales at 260 kg – bombs included.
