[The concept of functional strength in the problem of establishing objective biomechanical requirements for systems to protect and rescue aircraft crews]

Area of Science:

• Biomechanics
• Materials Science
• Safety Engineering

Context:

• Ambiguous biomechanical requirements for protection and rescue means hinder objective quality assessment.
• Current standards lack a unified approach to evaluate the effectiveness of safety and rescue equipment under diverse conditions.

Purpose:

• To propose an objective methodology for formulating biomechanical requirements.
• To introduce the functional strength concept for evaluating protection and rescue means.
• To enhance the development of complex requirements for safety and rescue equipment.

Summary:

• The paper introduces the functional strength concept to objectify biomechanical requirements for protection and rescue means.
• This concept integrates mechanical properties, biomechanical system specifics, and functional outcomes of adverse effects.
• It facilitates the development of complex, probabilistic requirements for various scenarios.

Impact:

• Provides a framework for more rigorous and reliable evaluation of safety and rescue equipment.
• Improves the standardization and clarity of biomechanical testing and certification.
