FIELD: aviation.
SUBSTANCE: pilotless helicopter comprises the motor, which is connected to the main rotor gear box by virtue of the transmission gear, located at the self supporting body frame with the forebody, a part of the body frame of which is designed as the fuel tank. The motor is separated from the gear box by virtue of the fire seal with the annular slot. The part of the transmission gear between the motor and the main rotor gear box is designed as the externally actuated clutch and the expansion clutch. The fan is mounted on the clutch collars opposite to the annular slot from the motor side, and the main rotor brake is mounted on the expansion clutch collars from the gear box side. The front dome-shaped section with the disposable load closable cavity is made in the forebody. The air intake orifices are implemented into the forebody on the outside of the front section opposite to the motor main heat-generating parts, and the outlet slots are implemented into the body frame behind the motor and gear box heat-generating parts.
EFFECT: helicopter weight and size reduction.
