A Study on Quality Improvement for Reducing Residual of K677 Gun Propellant

Key Points

• This research aims to understand the causes of residuals from K677 propellant during artillery tests and improve quality to minimize these residues.
• Identified causes of residuals during test firings using K677 propellant.
• Conducted component analysis of residuals to ascertain their properties.
• Tested various liner prototypes to minimize residuals while meeting military requirements.
• Evaluated the impact of improvements on muzzle wear rates.
• Residuals were confirmed to originate from a specific component of the propellant liner.
• No significant bias was found between different lots of propellant during single shot tests.
• Continuous firings did not significantly increase residual buildup or affect subsequent shots.
• Improvements led to a reduction in residuals while also considering user psychological impacts.
