Problems solved by technology

However, the current triplanes focus on the aerodynamic characteristics and ignore the stealth characteristics, which leads to the large RCS (radar cross-section) of the triplanes, and the low survivability of the aircraft during combat

Abstract

The invention belongs to aircraft design in the technical field of aviation, relates to aerodynamic configuration of a three-surface aircraft, and solves the problem that the RCS of the three-surface aircraft with high aerodynamic performance is too large. The aerodynamic configuration comprises the aerodynamic configuration of an aircraft body, wings, canard wings, a horizontal tail and vertical tails and is characterized in that the wings, the canard wings and the horizontal tail form three surfaces for bearing aerodynamic force, the aircraft body has stealth performance, the full-flight-simulator double vertical tails incline outwardly, and double ventral fins incline outwardly. The aerodynamic configuration has the advantages that the aircraft using the aerodynamic configuration is high in lift-drag ratio, good in operability, good in stability and good in stealth performance.

Description

technical field [0001] The invention relates to an aerodynamic layout of a three-plane aircraft, which belongs to the aircraft design direction in the field of aviation technology. Background technique [0002] Three-plane aircraft is the aircraft that forms aerodynamic bearing surface by canard, wing and flat tail. Although the triplane has a slight increase in weight due to the addition of canards, the aerodynamic performance of the triplane is good at low and ultra-low altitudes, and its maneuverability is strong at high altitudes. Therefore, it has received extensive attention from the aviation industry at home and abroad. At present, Russia's Su-30SM, Su-33 and Su-34 and other three-plane aircraft are equipped with a large number of troops, which has improved the combat capability of the aviation unit. However, the current triplanes focus on the aerodynamic characteristics and ignore the stealth characteristics, which leads to the large RCS (radar cross section) of the...
