Cross-medium aircraft

Abstract

The invention discloses a cross-medium aircraft. The aircraft comprises an aircraft body, hydrofoils are connected to the aircraft body through a storage mechanism, main wings are connected to the aircraft body through a discarding mechanism, a water inlet and an air inlet are further formed in the aircraft body, an air nozzle and a water nozzle are further formed in the tail end of the aircraft body, the air inlet communicates with the air nozzle through an air channel, and the water inlet communicates with the water nozzle through a water channel; a tail vane is also connected on the rear end of the aircraft body; the aircraft is additionally provided with the main wings to provide lifting force for aerial working conditions, and the main wings are upper single wings to reduce water entry impact. The attack angle of the main wings is changed by adjusting pitching of the aircraft so as to achieve the purpose of adjusting the lifting force of the main wing. An overwater / underwater cross-medium engine technology is adopted, and an air spraying port and a water spraying port are formed in the tail end to be matched with a propelling mode of air spraying and underwater water spraying.Retractable hydrofoils are additionally arranged on the front portion of the aircraft and used for providing enough lifting force in the take-off process, and the hydrofoils are retracted under the stable operation condition to reduce navigation resistance. When the aircraft is attacked in water, the main wings are discarded, the navigation resistance is reduced, and the navigation speed is increased.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a trans-medium aircraft. Background technique [0002] The trans-medium vehicle is a new type of trans-medium weapon that can be launched from the water or underwater, and can navigate both in the air and underwater. Its characteristic is that it can avoid the detection of enemy ships when navigating underwater, and has good concealment; it has high speed and efficiency when navigating in the air outside the detection range of enemy ships. [0003] Generally, due to the large navigation resistance, small platform space, and weight limitation, traditional underwater vehicles have a smaller range than air missiles, and cannot effectively break through the enemy's defense circle. After the aircraft is launched, it is easy to expose the position of the mother ship. For missiles that attack from the air, the formation of enemy ships already has a three-dimensional air de...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the platform, the flying aid vehicle cannot be launched underwater, and can only perform single-mode cross-media work from air to water in one direction, resulting in defects such as poor launch concealment and lack of penetration methods, which directly affect its combat effectiveness.

[0005] Moreover, due to the large navigation resistance, small platform space and weight restrictions of traditional underwater vehicles, their range is relatively small compared to air missiles.
