Introduction

Evolution and analysis of standard technology

This revision strengthens the dynamic constraint on rotor instability energy, and adds a momentum correction factor algorithm:
Protection calculation formula iteration: P_res=(f_m×R_m×ε_B×t)/SF_spec

Safety protection classification system

Protection level	Energy limit (N·m)	Application scenario	Necessary equipment
A	≤2,000	Low-speed calibration scenario	Wear goggles before operation
C	≤60,000	Aeroengine dynamic balancing	Double-layer barrier protective cover

Major risk reduction plan

Debris penetration risk control:

Actual measurement of a certain type of turbine drive shaft found that 36g titanium alloy fragments generated
unit area energy of Pred,material=280mN·m/mm²
