Product name: Super alloy wings — Grid fin (TC4)
Application scenario:
Core application: Space launch vehicles (key support for reusable technology)
After the rocket completes its launch mission, when the first stage/booster re-enters the atmosphere, the grid fin deploys from its folded state and generates aerodynamic torque by adjusting its angle. It corrects the vehicle attitude deviation, precisely controls the ballistic trajectory, and guides the vehicle to land vertically at the predetermined recovery platform (land recovery site or offshore recovery vessel).
Product advantages:
Efficient and precise aerodynamic control: Using a grid array structure, it operates stably across subsonic and supersonic speed ranges, avoiding the "drag peak" problem of traditional flat plate fins. The control torque is greater, enabling independent roll, pitch, and yaw adjustments. Combined with engine thrust vector control, it reduces the rocket landing area by more than 80%.
Strong adaptability to extreme environments: Using special materials such as titanium alloy and high-temperature alloy, combined with serrated leading edge design to dissipate shock waves, it can withstand re-entry temperatures above 2000℃ (with high-temperature resistant coating) and high overload impacts. Vibration amplitude is reduced by 30%, eliminating structural failure risks.
Lightweight and space optimization: The weight is only 1/3 of similar products. The folding structure clings to the vehicle body during launch and functions efficiently after deployment, significantly reducing rocket payload capacity loss and adapting to the limited space requirements of spacecraft.
Outstanding economic value: It provides core support for rocket reusability, reduces launch costs; with both standardization and customization capabilities, it becomes a key incremental component for reusable rockets.
