FIRE CRANE HELICOPTER Russian patent published in 2023 - IPC B64C27/08 B64D1/16 B64D1/22 

FIELD: aviation; designs of fire helicopters.

SUBSTANCE: helicopter contains a carrier system, a power plant, turboelectric generators, a fuselage with front and rear cockpits for pilots and crane operators, left and right pylons with rotary main tail rotors, pylons with racks of a four-point controlled self-propelled landing gear, a crane system for securing cargo or an autonomous tank with a hydraulic monitor and intake hose water in the technological cavity of the fuselage. In the front and rear parts of the fuselage there are two main rotors of a rigid design, hingeless fastening to the propeller hub at the end of the shafts. The shafts are installed in pairs with a shaft camber of 10-20 degrees and are inclined at an angle of not more than 5 degrees in different directions from the vertical perpendicular to the longitudinal axis of the helicopter fuselage. The power and turboelectric generators are located in the lower part of the fuselage and are separated from the cockpit by a fireproof bulkhead. The technological cavity for placing the cargo allows you to place the centre of mass of the cargo as close as possible to the centre of mass of the helicopter. The helicopter has an electronic control system for the carrier system, tail rotors, crane system.

EFFECT: improved flight controllability in all modes, increased ground speed.
