Crash Survival Design Guide (DTIC)

This five-volume guide presents criteria and data for crash-resistant Army aircraft, including design principles for landing gear and fuselage under various impact modes, rollover dynamics, and occupant protection.

Current structural design requirements cover longitudinal, vertical, lateral, and rollover impact conditions. Analytical methods describe energy-absorption limits, deformation criteria, and occupant safety measures.

  • Longitudinal, vertical & lateral impact analysis
  • Complex rollover dynamic modeling
  • Crash-resistant structural element design
  • Energy-absorbing subfloor & landing gear guidelines
