AI Technical Summary

⚠Technical Problem

Existing locking screws for projectiles, such as high-explosive shells, fail to effectively manage internal pressure increases due to external thermal influences without causing complex reactions or structural instability, posing safety hazards.

⚗Method used

A locking screw with a pressure relief channel and a closure element that fails at a defined pressure limit, allowing controlled pressure release through the channel, designed to withstand mechanical stress and temperature changes.

🎯Benefits of technology

The solution provides robust and reliable pressure relief without affecting projectile performance, ensuring safety by preventing catastrophic failures and reducing hazards.

Abstract

The invention relates to a closing screw (10) for a projectile (100), comprising a screw body (14) extending along a central longitudinal axis (M), wherein a channel (16) is formed in the screw body (14), which extends relative to the central longitudinal axis (M) from a first side (18) of the screw body (14) to a second side (20) of the screw body (14), wherein a closing element (22) is arranged in the channel (16), which closes the channel (16) and is configured in such a way that, when a defined limit pressure in the channel (16) is exceeded, the closing element (22) at least partially fails and at least partially releases the channel (16).
