ANALYSIS OF LIMITING SAFE OPERATING CONDITIONS FOR AVIATION WEAPON SYSTEMS AND AND FACTORS AFFECTING THE THERMAL STATE OF A SMALL-CALIBRE BARREL SYSTEM
Keywords:
Key words: thermal resistance; transient heat transfer; barrel thermal state; aviation systems; thermomechanical stress; heat flux; thermal diffusivity; measurement uncertainty; model validation; engineering safety.Abstract
Examines the scientific and methodological basis for assessing the thermal state and heat-resistance limits of aviation weapon systems, with particular attention to the barrel assembly of a small-calibre automatic artillery system. Repeated energy input during operation produces transient temperature gradients, thermal expansion, cyclic stresses and time-dependent changes in material properties. These phenomena can influence dimensional stability, fatigue life, surface integrity and the reliability of adjacent components.
