Aeronautical Fluid Mechanics Principles:
• Suction Force: F = ΔP × A = (P_cabin - P_ambient) × Area
• Choked Outflow Velocity: v = √(γ · R · T) · M_exit ≈ 1,080 ft/s (Mach 1.0 at orifice)
• Uncontained High-Energy Fragment: Fan blade kinetic energy E_k = 0.5 · I · ω² ≈ 150+ kJ exceeding nacelle kevlar containment ring absorption limit.
