数字化赋能自燃推进剂点火延迟时间的实验研究OA
Digitally Enhanced Measurement of Ignition Delay Time Measurement for Hypergolic Propellants
自燃推进剂因不需要点火装置,是推进剂的主流发展方向之一,其主要指标是点火延迟时间.本实验采用自制落滴实验装置研究了推进剂燃料与高浓度过氧化氢氧化剂的点火延迟特性,并通过数字化设计优化了实验过程.针对点火延迟时间测试中大批量图片的处理难题,本实验基于YOLOv8深度学习算法自编Python软件,通过图像识别实现了对推进剂自燃点火延迟时间的分析,从而高效准确地处理实验数据.此外,将该创新实验内容引入大学化学课程教学,有效提高了学生的学习兴趣.
Hypergolic propellants represent a predominant development direction in propulsion systems due to their ignition device-free characteristic,with ignition delay time serving as their primary performance metric.This study employed a custom-designed drop-test apparatus to examine the ignition characteristics between propellant fuel and high-concentration hydrogen peroxide oxidizer,while optimizing the experimental procedure through digital design.To overcome the challenge of processing extensive image data in ignition delay time measurement,we developed Python-based software incorporating the YOLOv8 deep learning algorithm.This implementation of image recognition technology enables precise analysis of propellant self-ignition delay time,facilitating efficient and accurate experimental data processing.Furthermore,integrating this innovative experimental approach into the"University Chemistry"curriculum has demonstrated significant enhancement in student engagement and learning motivation.
