Abstract

The invention discloses an ignition experimental device and an ignition experimental method of an airplane fuel tank. A temperature and a pressure of the ignition experimental device are controlled respectively through a heater and a boosting pump to simulate status change in the fuel tank, extinguishment, burning and exploding of sparks in the fuel tank when the fuel tank is punctured by a threatening weapon and the sparks are generated with different anti-explosion materials placed in the airplane fuel tank or in different filling manners. Changes of the temperature and the pressure in the fuel tank are recorded through temperature sensors and pressure sensors at different positions so that performances of different anti-explosion materials and different filling manners under different flight statuses can be determined. The ignition experimental device is simple in structure. The temperature sensors and the pressure sensors are respectively connected to a computer. A ventilating hole and a vacuum pump, a fuel inlet and a pump, and a fuel outlet are respectively connected to each controlling button on a control panel. An ignition device is connected to a power supply. The device and the method can provide basis for selection of built-in materials and the filling manners in the airplane fuel tank according to an experimental result, thereby performing high-survivability evaluation to the airplane fuel tank.

Description

technical field [0001] The invention belongs to the field of aircraft fuel tank survivability design, in particular to an aircraft fuel tank ignition experimental device and an experimental method. Background technique [0002] Among the various system components of the aircraft, the fuel tank is the most vulnerable part, and it is extremely easy to burn and explode under the attack of threat propagators. The combustion and explosion of the fuel tank will cause burns and shocks to the fuel tank and adjacent structural systems, causing serious damage. Anti-flammation and anti-explosion of fuel tank is the main content to improve the high survivability of aircraft. At present, the commonly used fuel tank anti-explosion suppression methods for military aircraft can be divided into two categories: filling the fuel tank with anti-explosion and anti-explosion materials and inerting the fuel tank. Filling the fuel tank with flame-proof and explosion-suppressing materials refers t...
