Abstract

The invention discloses a parallel twin-type rotary-rotor aircraft and belongs to the technical field of aircrafts, in particular to a rotary-rotor aircraft with torque balance on both sides. The technical scheme includes that the parallel twin-type rotary-rotor aircraft comprises a fuselage, a frame, two power units, rotors and a tail; the fuselage is fixed onto the front end of the frame, the power units are symmetrically arranged on two rear sides of the fuselage, the rotors are arranged above the rear portion of the fuselage and are connected with the frame fixedly through a main column, the tail is fixed onto the rear end of the fuselage, the tail has two paired vertical tail fins, and the two tail fins of the tail are respectively arranged right behind the power units. The parallel twin-type rotary-rotor aircraft is widely applicable to the fields of searching, tourism, surveying, forest fire prevention, agricultural planting and the like.

Description

technical field [0001] The invention relates to a parallel twin-engine autogyro aircraft, which belongs to the technical field of aircraft, and in particular relates to an autogyro aircraft. Background technique [0002] Autogyro is a kind of rotorcraft that obtains lift by rotor rotation instead of power drive. It generally has a propeller to provide forward power, and uses the relative airflow during forward flight to blow the rotor to rotate. [0003] The autogyro has the characteristics of simple operation, low price, and safe and reliable performance. The autogyro is widely used in fields such as search, tourism, surveying, forest fire prevention, and agricultural planting. With the rapid development of my country's economy, the demand for autogyro will be more extensive. [0004] Such as image 3 and Figure 4 Shown: A common autogyro is driven by a single engine. Once a failure occurs, it can only be forced to land. Bad ground conditions will bring serious consequen...
