Problems solved by technology

[0003] However, the existing fire-fighting helicopters are affected by smoke and air currents during mountain fires, and are difficult to drive, requiring high drivers and prone to crash accidents; at the same time, severe smoke and dust will block the driver's field of vision, plus Carrying limited fire extinguishing materials and inaccurate dispensing will greatly increase the difficulty of fire extinguishing; moreover, most fire helicopters use a single engine in the middle, and once they stop in the air due to the harsh working environment, the situation will be very critical

Abstract

The invention discloses a double-engine coaxial aircraft for fire fighting. The aircraft comprises a main frame, a flexible water tank, motors, coaxial blades, a water supply and drainage device and a visual module, a top shell is fixedly installed at the top end of the main frame, a stabilizing frame is fixedly installed on the inner wall of the middle of the bottom end of the top shell, the coaxial blades are rotatably installed on the upper portion of the stabilizing frame, the upper portions of the coaxial blades are located on the outer side of the top shell, the motors which are oppositely arranged left and right are fixedly installed in the top shell, belts are installed between the motors and the coaxial paddles in a sleeving mode, an air inlet barrel is fixedly installed at the left end of the top shell, and a draught fan is fixedly installed at the right end of the top shell. The aircraft is reasonable in structural design, a high-precision unmanned driving mechanism is matched with self-cleaning imaging equipment, stable fire extinguishing is achieved in a dangerous environment, the safety of rescue workers is guaranteed to the maximum extent, the water taking device with the variable size guarantees convenient control over the water taking size and advancing control, the double-engine coaxial combination is adopted, the error-tolerant rate is higher, a self-cooling system is matched, and the use is safer.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an aircraft for twin-engine coaxial fire fighting. Background technique [0002] A wildfire is an uncontrollable fire that occurs in the forest. Usually caused by lightning. Some other common causes are human carelessness and intentional arson. In Australia, wildfires frequently occur in summer, because summer is hot and dry, and fire helicopters are widely used when fighting wildfires. [0003] However, the existing fire-fighting helicopters are affected by smoke and air currents during mountain fires, and are difficult to drive, requiring high drivers and prone to crash accidents; at the same time, severe smoke and dust will block the driver's field of vision, plus Carrying limited fire-fighting materials and inaccurate spreading will greatly increase the difficulty of fire-fighting; moreover, most fire-fighting helicopters use a single-engine mid-engine. Once the helicopter stops in...
