1results about How to "Reduce heat flow" patented technology

This invention relates to a drag-reducing and heat-cooling device combining a partitioned base with a liftable central structure. The device includes a central base structure, a peripheral base structure, a drive mechanism, and a cold air flow control system. The central base structure comprises an arc-shaped surface and a lifting rod. The arc-shaped surface is located at the center of the peripheral base structure surface. When the lifting rod is compressed, the arc-shaped surface remains flush with the peripheral base structure, forming an integrated heat shield. The cold air flow control system includes a gas pipeline, a cold air storage cylinder, and an ejector device. Cold air is uniformly injected from the ejector device through the gas pipeline and the lifting rod onto the surface of the central base structure, forming a gas film. The drive mechanism is located inside the reentry capsule and drives the lifting rod to extend or retract into the reentry capsule, thereby raising or lowering the arc-shaped surface of the central base structure. This invention effectively reduces the impact of heat flow while reducing aerodynamic load, improving the safety and reliability of reentry.
