The invention provides a linear rotor propeller helicopter. A cross beam is arranged on the gravity center of the top of a helicopter body, a left rotor wing is arranged on the left side of the cross beam close to the helicopter body, a left first propeller is arranged on the left side of the left rotor wing, and a left second propeller is arranged on the left side of the left first propeller. A right rotor which is symmetrical to the longitudinal shaft of the body is arranged at the right side of the cross beam next to the body. A right first propeller is arranged on the right side of the right rotor wing, a right second propeller is arranged on the left side of the right first propeller, the rotating surfaces of the left rotor wing and the right rotor wing are not overlapped, and the left first propeller, the left second propeller, the right first propeller and the right second propeller are fixed pitch propellers with the same propeller pitch. The rotation directions of the left rotor and the right rotor are opposite, the rotation directions of the left first propeller and the left second propeller are opposite, the rotation directions of the right first propeller and the right second propeller are opposite, an undercarriage is arranged below the fuselage, and the unmanned aerial vehicle is suitable for being applied to occasions such as pesticide spraying and forest fire extinguishing.
