Rapid aircraft fuel cleanliness detection method

Abstract

The invention discloses a rapid aircraft fuel cleanliness detection method. In a stage of establishing pure aircraft fuel cleanliness scattering data, a first computer acquires brillouin scattering signals of first to eighth reflecting mirrors at different time periods by a first ICCD, draws brillouin scattering signal data generated at different optical paths, and establishes a brillouin scattering signal database of pure aircraft fuel according to the acquired brillouin scattering signal data; at the cleanliness detection stage of the to-be-detected aircraft fuel, the acquired brillouin scattering signal data and the established brillouin scattering signal database of the pure aircraft fuel are compared by a second computer, so that the cleanliness of the to-be-detected aircraft fuel can be obtained. According to the invention, when the aircraft fuel is detected, deep-seated aircraft fuel can be subjected to non-contact detection, so that the complex working procedures and long detection time of the traditional sampling detection are prevented; the rapid aircraft fuel cleanliness detection method is long in timeliness and capable of resisting interference.

Description

Technical field [0001] The invention involves a photon detection technology, which specializes in the rapid detection method of aviation fuel cleanliness. Background technique [0002] Aviation fuel is the "blood" of the aircraft, and the height of the "blood" cleanliness directly affects the safety of the aircraft.According to the US Air Force statistics, 50%of the 33%of the secondary accidents are caused by low -quality fuel.In the 1970s and 1980s, the water and mechanical impurities contained in the pipeline caused severe frozen Gra pipelines on the Qinghai -Tibet Plateau, causing serious economic losses.However, most of the detection methods adopted by oil products are chemical analysis methods, and the equipment used in this method is complicated, the analysis time is long, the workload is large, the sterile conditions are harsh, and the timeliness is poor.Moreover, in the case of war and emergency training, the naked eye observation method is used for high -time effect.

Problems solved by technology

In the 1970s and 1980s, the water and mechanical impurities contained in the oil in the pipeline caused severe freezing of the Gela pipeline on the Qinghai-Tibet Plateau, causing serious economic losses

However, most of the detection methods currently used for oil products are chemical analysis methods, and the equipment used in this method is complicated, the analysis time is long, the workload is heavy, the sterile conditions are harsh, and the timeliness is relatively poor

Moreover, in wartime and emergency training situations, the naked eye observation method is used for high timeliness. The subjectivity and low accuracy rate caused by human factors and individual differences can be imagined, and its water content is even more difficult to judge.
