AI Technical Summary

Technical Problem

Existing unlocking systems in aviation technology, particularly for missile positioning systems, fail to meet safety and reliability requirements under extreme conditions due to complex functional chains that are susceptible to failures, malfunctions, and electromagnetic interference.

Method used

A mechanical unlocking release unit with a plastically deformable or breakable release element, tolerance compensation springs, and lever kinematics, which ensures precise and irreversible unlocking processes, minimizing dependencies on electronic components and reducing susceptibility to electromagnetic interference.

Benefits of technology

The unlocking release unit provides reliable, precise, and irreversible unlocking under extreme conditions, ensuring stable actuator positioning and minimizing the risk of unintentional unlocking or malfunction, even under varying temperatures, vibrations, and external loads.
