Abstract

The invention belongs to the field of aircraft design, and particularly relates to a water-air critical aircraft. The water-air critical aircraft comprises a fuselage, wings, a heading-effect face, longitudinal effect faces, pontoons and a water propeller; the wings are mounted on the two sides of the fuselage, and the heading-effect face is mounted on the back of the fuselage; the longitudinal effect faces are mounted on the two sides of the tail of the fuselage, and the pontoons are mounted on the wings on the two sides; and the water propeller is mounted at the tail. According to the water-air critical aircraft, through matching of the gravity center, the buoyant center and the pneumatic pressure center of the water-air critical aircraft, the water-air critical aircraft can float on water and fly close to the water surface; by using the water power propeller, the water-air critical aircraft has extremely high acceleration performance; by arranging the two pontoons, the water-air critical aircraft keeps stable navigation under the special sea conditions; in the cruising process, only the propeller exists in the water, and thus the water-air critical aircraft has good sonar invisibility; and the water-air critical aircraft gets close to the water surface when berthing and navigating, and thus has good radar invisibility.

Description

technical field

[0001] The application belongs to the field of aircraft design, in particular to a water-air critical aircraft. Background technique

[0002] In the field of water-air critical aircraft, the current mainstream aircraft in the world include hydrofoil boats, ground-effect aircraft and conventional seaplanes. Strictly speaking, the hydrofoil boat does not belong to the aircraft category. Through a set of hydrofoils, the draft of the boat is reduced during the driving process, the water-stained area is reduced, and the viscous resistance of water to the boat is reduced, thereby improving its performance to a certain extent. Driving speed and efficiency; the ground effect aircraft uses the ground effect to make it glide on the water surface, and takes advantage of the relatively flat water surface driving environment and parking environment, such as the "Caspian Sea Monster" ground effect aircraft of the former Soviet Union, but its acceleration performance is poo...
