New-generation aviation fire protection standard flame burner

Abstract

The invention relates to a new-generation aviation fire protection standard flame burner. The burner comprises a flame jetting device, an adjustment movement device, a flame calibration device and a clamping device, the flame calibration device and the clamping device are distributed in the length direction of the adjustment movement device, and the clamping device is used for fixing a test samplepart; the flame jetting device is slidingly arranged on the adjustment movement device, the adjustment movement device has a first position, a second position and a third position, when the flame jetting device slides to the first position and the second position, a flame outlet of the flame jetting device directly faces the flame calibration device to detect the heat flow and temperature of theflame, and when the flame jetting device slides to the third position, the flame outlet of the flame jetting device directly faces the test sample part to test the fire protection and fire resistanceperformance of the test sample part. According to the new-generation aviation fire protection standard flame burner, just by moving the flame jetting device, temperature and heat flow calibration of the standard flame and fire protection and fire resistance tests of the test part can be obtained, and the flame characteristic parameters such as flame temperature and heat flow density can be strictly controlled.

Description

technical field [0001] The invention belongs to the field of aviation fire protection. It involves a new generation of aviation fireproof standard flame burner. Background technique [0002] Safety has always been the most important consideration in the design process of civil aircraft. According to statistics, in U.S. civil aviation aircraft crash accidents, the number of people who were burned to death after the crash accounted for 15% of the total number of deaths, and in those crashes that could survive the crash, the proportion of people who were burned to death was as high as 40%. Whether in flight or on the ground, fire is one of the most serious threats to aircraft. At the same time, aircraft fire is also one of the common accidents in the process of aircraft use and maintenance. [0003] According to the statistics of the National Transportation Safety Board (NSTB) on fire accidents of various civil aircraft from 1983 to 2015, fuel oil is the greatest risk in airc...

Problems solved by technology

Although extensive and effective research has been carried out internationally on flame characteristics and standard burners in fire tests, relevant domestic standards, including the latest revisions of HB6167.14 and HB7044 (2014), continue to use traditional gas or Liquid burners, which will undoubtedly have a major impact on the international fire protection and airworthiness certification of Chinese engines, there is an urgent need to establish fire test standards and methods based on NexGen standard burners
