Abstract

The invention relates to the technical field of aircrafts, in particular to the technical field of aerodynamic layout of aircrafts, and particularly relates to an aircraft. A retractable and extendable vertical fin is arranged on the aircraft; and the vertical fin is used for enhancing the navigation stability of the aircraft in the extending state. The invention provides the extendable and retractable vertical fin arranged for the aircraft, the course stability of the aircraft can be improved, the problems of poor course stability and high control risk of the take-off and landing section of aflying wing layout aircraft can be partially solved, and meanwhile, the efficient aerodynamic configuration of the flying wing layout is maintained.

Description

technical field [0001] The present invention relates to the technical field of aircraft, in particular to the technical field of aircraft aerodynamic layout, and in particular to an aircraft. Background technique [0002] Aircraft with a conventional layout usually have a vertical tail at the tail of the fuselage, and the vertical tail mainly plays a role in increasing the heading stability of the aircraft. The flying wing layout without vertical tail is an advanced aircraft layout design, which has the characteristics of high aerodynamic efficiency, good stealth performance, and strong loading capacity. It has been applied in military aircraft, and it is also an important research direction for civilian aircraft. However, the vertical tail is canceled for the flying wing layout aircraft, which leads to the unstable heading of the aircraft and increases the difficulty of flight control, especially during the take-off and landing phase of the aircraft. During the takeoff and...
