AI Technical Summary

Technical Problem

When conventional amphibious aircraft take off and land at sea, they are difficult to take off and land due to the influence of sea storms, and the take-off and landing distance and speed are far higher than other aircraft. Especially in high sea conditions, the aircraft is difficult to take off and land and is dangerous, which limits its frequency and range of use.

Method used

A new type of jet lifting and stabilizing amphibious aircraft is designed, and a system including intake fan, pressurized gas storage tank, shunt pipeline, aerial state perception device, intelligent analysis device, jet control device and multiple air chambers are used. The navigation data is detected through the aerial state perception device, the intelligent analysis device analyzes the data and generates a jet control scheme. The jet control device adjusts the jet state of the air chamber to assist the aircraft in a smooth flight.

Benefits of technology

By distributing multiple air chambers at the bottom of the aircraft and adjusting the jet volume according to the control plan, the aircraft can be assisted in smooth flight, solving the problem of difficulty in taking off and landing in high sea conditions by conventional amphibious aircraft, and improving the safety and stability of take-off and landing.
