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.

▶ Volume I – Design Criteria & Checklists
▶ Volume II – Crash Impact Conditions & Human Tolerance
▶ Volume III – Aircraft Structural Crash Resistance
▶ Volume IV – Seats, Restraints, Litters & Cabin Delethalization
▶ Volume V – Postcrash Survival

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
