China Spacesat(SH:600118) Ke Ji Ri Bao·2025-12-02 06:00Core Viewpoint - The successful delivery of China's first offshore rocket recovery platform "Navigator" marks a significant advancement in the development of a stable, reliable, and precise rocket recovery system at sea [1] Group 1: What is Network Recovery? - Network recovery is a unique method of vertical landing recovery, which involves deploying a network of cables at high altitudes to capture the rocket as it descends [2] - This method differs from traditional recovery techniques, such as parachute recovery and vertical landing, by utilizing a hook on the rocket that latches onto a grid-like structure [2] Group 2: Advantages of Network Recovery - Network recovery enhances the success rate of capturing and buffering during the recovery process through high coordination between the recovery system and the rocket's recovery device [3] - It is more forgiving on landing parameters, as the ground buffering system absorbs most of the rocket's kinetic and potential energy, reducing design requirements for the rocket's buffering structures [3] - The system simplifies the rocket's structure, improving efficiency and effectiveness, and can be adapted for different sizes of rockets [3] Group 3: Technical Challenges of "Navigator" - "Navigator" is the first offshore rocket recovery platform certified by a classification society, measuring 144 meters in length and 50 meters in width, with a displacement of 25,000 tons [4] - The platform requires high precision in positioning to coordinate with the rocket's landing, necessitating advanced design considerations for stability and load distribution [4] - The design must account for various sea conditions and the unique structural challenges posed by the network recovery system, which has a high center of gravity and significant weight [4]
