About
The Antenna Reflector Hold-down Lock (mechanical) Type 1 is a critical component of an antenna hold-down system, engineered to keep antenna reflectors securely stowed during launch and other mission phases. Released in 2011, this mechanism offers a guaranteed service life of 6 years. It is designed to withstand extreme space environments, operating within a temperature range of -100 to +100 °С. The lock provides a substantial clamping force of 600 kg and can handle an ultimate bending moment of 200 N·m at its interface with the spacecraft. Its operational life is defined by a minimum of 50 actuations, ensuring reliability over multiple deployments if required. With a mass of only 0.35 kg, it is a lightweight solution for spacecraft antenna deployment systems.
