Core Viewpoint - The article discusses the function and evolution of the "排焰口" (exhaust ports) on rockets, highlighting their importance in the separation process of multi-stage rockets and the advancements in rocket technology over time [1][3][4]. Group 1: Function of Exhaust Ports - The primary function of the exhaust ports is to release high-temperature and high-pressure gases generated during the ignition of rocket engines during stage separation [1][3]. - Exhaust ports are designed to manage the gas flow and prevent damage to the lower stage of the rocket during the separation process [3]. Group 2: Evolution of Design - Historically, the design of exhaust ports has evolved, initially using rod structures to allow smooth gas discharge, as seen in earlier models like the Long March 2 and Long March 3 series [3]. - With advancements in rocket technology, newer designs have shifted towards smaller or even absent exhaust ports, as demonstrated by the Long March 2F, which adopted a grid hole design, and the Long March 5, 7, and 8, which utilize cold separation methods [3].
