A modular aircraft emergency weight-reducing safety fuel tank and its control method

Abstract

The invention relates to a modular aircraft emergency weight-reducing safety fuel tank and a control method thereof, comprising a plurality of fuel tanks that can be spliced ​​into a central fuel tank of an aircraft, and umbrella boxes for decelerating the fuel tanks for safe landing are arranged on both sides of the fuel tanks. The bottom and sides of the fuel tank are provided with an airbag box for the fuel tank to land smoothly to slow down the impact vibration, and the top of the fuel tank is fixed with an electric circuit for detecting various parameters of the thrown fuel tank and controlling the umbrella box and the airbag box. The control box starts the electric control box when the fuel tank is ready to be thrown, and controls and completes various functions until the fuel tank is recovered safely. Aiming at the weight loss problem of aircraft forced landing, the invention designs a modular throwable and recyclable fuel tank, which can quickly reduce the weight of the aircraft and reduce the amount of fuel carried, increase the safety of forced landing, and is environmentally friendly and pollution-free, and both the fuel tank and the fuel can be recycled Reuse.

Description

technical field [0001] The invention relates to the technical field of aircraft fuel tank structure design, in particular to a modular aircraft emergency weight-reducing safety fuel tank and a control method thereof. Background technique [0002] The airplane is one of the most significant inventions of the early 20th century, recognized as being invented by the American Wright Brothers, who made their flight on December 17, 1903 as "the first controlled sustained powered flight by a heavier-than-air aircraft" Recognized by the Federation of International Aviation (FAI), they founded the "Wright Aircraft Company" in the same year. Since the invention of the airplane, the airplane has increasingly become an indispensable tool of modern civilization. It has profoundly changed and influenced people's lives, and opened the history of people conquering the blue sky. [0003] As an important means of transportation, the safety of airplanes has attracted more and more attention. ...

AI Technical Summary

Problems solved by technology

[0006] (2) The high-altitude oil discharge rate is too slow and there is a risk of explosion

High-altitude oil discharge drains oil slowly through the oil discharge port. Due to the high oil temperature, too fast oil discharge or improper handling can easily cause high-altitude explosions. Too slow oil discharge rate will cause the aircraft to fail to make an emergency landing in time, increasing safety hazards

[0007] (3) High-altitude oil discharge is not recyclable, causing serious waste

Aircraft failures or emergencies may occur at various stages of aircraft flight. If they occur at the stage of aircraft takeoff, most of the aviation fuel will need to be discharged, resulting in serious waste.
