Crashworthiness Design Guide

Small Airplane Crashworthiness Design Guide - a nice study to review by Simula Technologies, for NASA.

you can score your aircraft by this guide!

1.1 Principles of Crashworthiness
The concept of crashworthiness refers to those vehicle design characteristics that protect the
occupant from injury or death during a crash event. Specifically, the designer strives to
(1) eliminate injuries and fatalities in relatively mild impacts, (2) minimize injuries and fatalities in
all severe but survivable crashes, and (3) minimize the damage to the aircraft structure in all
crash events (Reference 1-4). The fundamental principles of crashworthiness can be described
using the acronym CREEP (Reference 1-5):

• Container (fuselage structure)
• Restraint (restraint system, seats, and attachments)
• Energy Management (seats, restraints, fuselage, and engine mounts)
• Environment (items within the occupants’ strike zone)
• Post-crash Factors (fuel system, fire, and egress)

The most critical consideration for crashworthiness concerns the container, or the occupant
compartment. A strong, enclosed container must be maintained around the occupants in order
to create a survivable volume. Protection provided by the other four principles is of no value if
the cabin volume is compromised.
