Investment Rating - The report provides a "Buy" rating for the commercial aerospace industry, indicating an expectation of stock performance exceeding the market by more than 10% over the next 12 months [39]. Core Insights - The commercial aerospace industry faces challenges of high launch costs and long production cycles, with rocket recovery being a key solution to enhance launch efficiency. Effective recovery and reuse of rocket stages can significantly reduce costs, as demonstrated by SpaceX's Falcon 9, where recovering the first stage can lower costs by approximately one-third [10][11]. - There are two main categories of recovery solutions: arrow-mounted devices and platform equipment. Arrow-mounted devices include parachute recovery and vertical landing leg recovery, while platform equipment includes tower capture technology and net recovery [14][15]. Summary by Sections 1. Rocket Recovery Enhances Launch Efficiency - Increasing launch frequency and reducing costs are critical for the commercial aerospace sector, which currently suffers from a shortage of spacecraft relative to the number of satellites [10]. 2. Arrow-Mounted Recovery Solutions - **Parachute Recovery**: Maintains higher payload capacity but has lower reuse efficiency due to environmental factors affecting landing precision and increased maintenance costs [17]. - **Vertical Landing Leg Recovery**: Sacrifices some payload capacity for better landing precision and reuse convenience, successfully implemented by companies like SpaceX [19][20]. 3. Platform Equipment Recovery Solutions - **Tower Capture Technology**: Integrates recovery and launch processes, significantly reducing costs and launch intervals. This method requires high technical precision and poses risks if recovery fails [25][28]. - **Net Recovery**: A new collaborative recovery mode that enhances payload efficiency and landing adaptability, though it requires robust structural design to handle concentrated loads [30][31]. 4. Investment Recommendations - The report suggests focusing on companies involved in recovery buffer devices (e.g., Hengli Hydraulic), recovery vessels (e.g., China Shipbuilding), net recovery (e.g., Jiali Rope), and parachute recovery materials (e.g., Nanshan Zhishang) [33].
