Overview

Randomized trial examines fluid responses in UAV fuel tanks after dual-projectile impacts, suggesting design improvements.

Key Points

  • This study aims to investigate the dynamic responses of UAV liquid-filled tanks subjected to dual-projectile impacts under varying conditions.
  • Conducted high-velocity impact tests on UAV fuel tanks.
  • Utilized 3D digital image correlation technology.
  • Performed finite element simulations using the S-ALE algorithm.
  • Small projectile spacing and short intervals increased target plate impulse significantly with strong wave interference.
  • Long temporal intervals with small spacing led to the cavity shielding phenomenon, substantially reducing energy transfer.
  • Identified four deformation modes based on spatiotemporal coupling: oblique cross, normal cross, asymmetric pentagon, and hexagon.
