🔑 增強重點摘要

•The net-based recovery concept is being explored by Chinese aerospace entities as a potential solution for mid-air retrieval of smaller rocket stages or fairings, distinct from the heavy-lift booster recovery methods used by SpaceX.
•Research into flexible capture systems in China often involves high-strength synthetic fibers and dynamic tension-control mechanisms designed to absorb kinetic energy upon impact.
•This recovery method is being evaluated as a cost-effective alternative to propulsive landing, which requires significant fuel reserves that reduce payload capacity.
•Chinese aerospace engineers are investigating the use of autonomous drone-ship or barge-based net systems that utilize real-time trajectory correction to align with the descending booster.
•The development of net-based recovery is part of a broader Chinese strategy to diversify reusable launch vehicle technologies, including grid-fin control and retro-propulsion landing tests.

System utilizes high-tensile, heat-resistant polymer netting designed to distribute impact loads across a wide surface area.
Employs active tensioning winches that adjust net geometry in milliseconds based on booster descent velocity and wind shear data.
Integration of computer vision systems on the recovery platform to track the booster's center of gravity during the final seconds of descent.
Focuses on minimizing the 'hard-dock' shock that typically causes structural fatigue in reusable airframes.

Net-based recovery will enable higher payload-to-orbit ratios for small-lift launch vehicles.

By eliminating the need for heavy landing legs and excess fuel for landing burns, the vehicle can dedicate more mass to the primary payload.

China will achieve a successful mid-air capture of a sub-orbital test vehicle by 2028.

Current development trajectories and government funding for reusable launch infrastructure suggest a move toward full-scale testing within the next two years.
