AI Technical Summary

Technical Problem

The closed structure of traditional igniters makes it impossible to directly observe the internal flame propagation path, the dynamic evolution of the pyrolysis layer on the surface of the ignition propellant, and the distribution of intermediate products. The lack of correlation data for all-dimensional parameters hinders a deeper understanding of the combustion mechanism.

Method used

Design a visual testing device for the combustion and explosion boundary of ignition propellants, including a visual combustion chamber, a data acquisition system, and an insertion sensor, to achieve synchronous visual observation of flame morphology, combustion surface dynamics, overpressure process, and temperature changes, and to combine the data acquisition system for synchronous triggering and acquisition of pressure and temperature signals.

Benefits of technology

It enables simultaneous visualization and observation of multi-dimensional parameters within the igniter combustion chamber, optimizes the combustion process, reduces the risk of combustion and explosion, provides comprehensive data support, and enhances the depth and control capabilities of combustion mechanism research.
