Fixed-wing sea-air amphibious aircraft and control method

Abstract

The invention provides a fixed-wing sea-air amphibious aircraft. The fixed-wing sea-air amphibious aircraft comprises a housing assembly, a flight assembly and a pneumatic buoyancy assembly; the flight assembly comprises a fixed wing (3) and rotor wing assemblies, and the fixed wing (3) and the rotor wing assemblies are installed on the housing assembly; the pneumatic buoyancy assembly comprises an air bag and an air charging and discharging structure, the air bag is connected with the air charging and discharging structure, and the air charging and discharging structure can perform air charging and discharging on the air bag; the air bag is installed on the housing assembly, a containing space is formed in the housing assembly, and the air charging and discharging structure is partially or completely located in the containing space. The invention further provides a control method using the fixed-wing sea-air amphibious aircraft. The fixed-wing sea-air amphibious aircraft can achieve large-range flying observation in air and long-voyage gliding observation in water and can be switched between different modes of motion in water and in air by means of the vertical taking-off and landing function.

Description

technical field [0001] The invention relates to an aircraft, in particular to a fixed-wing sea-air multi-habitation aircraft and a control method. Background technique [0002] As an emerging underwater mobile observation platform, underwater glider has shown more and more important application value in military and civilian fields such as marine resource exploration, environmental monitoring, and submarine reconnaissance due to its advantages of low power consumption, long range, and low cost. . It changes its own net buoyancy through the buoyancy adjustment mechanism and adjusts the internal center of gravity position through the attitude adjustment mechanism, so as to complete the adjustment of floating, diving and pitch angle and roll angle. Gliders only rely on net buoyancy as a driving force, and their sailing speed and maneuverability are not as good as other propeller-driven underwater vehicles. At present, a variety of underwater gliders have been developed at hom...

AI Technical Summary

Problems solved by technology

At present, the sea-air amphibious vehicles developed abroad all adopt the rotor type, and their common disadvantage is that the air and underwater endurance are extremely limited, which cannot meet the needs of long-term joint sea-air observations
