A subsonic target aerodynamic configuration

Abstract

An embodiment of the present invention discloses a subsonic target aerodynamic configuration, characterized in that the wing-body fusion body comprises a fusion fuselage and a fusion wing arranged onboth sides of the fusion fuselage, an air inlet is arranged on the top of the fusion fuselage, a vertical tail ventral fin fusion body is arranged at one end of the fusion wing away from the fusion fuselage, and a flap aileron is also arranged on the fusion wing. The invention is characterized in that the wing-body fusion body comprises a fusion fuselage and a fusion wing arranged on both sides ofthe fusion fuselage. The embodiment of the invention provides a subsonic target aircraft aerodynamic configuration for reducing drag and increasing aerodynamic efficiency, which adopts flying wing configuration and further improves aerodynamic efficiency through wing aerodynamic torsion and geometrical torsion, so that under the condition of the same power system, the speed and load can be increased and the flight distance can be increased; At the same time, the fuselage and wing skin can be integrally formed due to the wing-body integrated flying wing layout, which reduces the processing steps and the number of molds, and reduces the processing cost.

Description

technical field [0001] The invention relates to the technical field of aircraft aerodynamic layout design, in particular to an aerodynamic layout of a subsonic target drone. Background technique [0002] The target drone is a special powered unmanned aerial vehicle, which is used as an air maneuvering target simulator to test the tactical and technical performance of the air weapon system and the training and exercises of combat troops. With the rapid development of aviation technology, target drones have become an important part of military aircraft. The target drones that China has developed include low-speed target drones, subsonic target drones, supersonic target drones, rotor target drones and solid target drones, and the types are relatively complete. [0003] The main feature of the low-speed target drone is that the flight speed is below 0.4Ma. The current low-speed target drone products have a flight speed of no more than 100m / s. Typical products include the B-2 an...

Problems solved by technology

[0004] The relative aerodynamic efficiency of the conventional layout target drone is not high. To increase the speed and load and increase the range, a stronger power system must be used, which increases the cost. Moreover, the conventional layout target drone has many components, which is time-consuming and labor-intensive to process, and the manufacturing cost is high. , does not conform to the principle of low cost, so there must be a new form of aerodynamic layout that can improve the defects of the conventional layout on the premise of meeting the control requirements of the target machine
