Jiang Zhengqing, upon hearing Jiang Cheng's question, didn't immediately present his own answer, but instead took a moment to think before speaking.
Regarding the future development of rocket technology, I have some immature ideas here, but they're just simple thoughts without specific implementation methods.
Since Jiang Cheng asked for his views on the future of rocket technology, Jiang Zhengqing shared his previous thoughts.
"I believe the biggest problem with rockets currently is the issue of propulsion energy. All rockets nowadays use solid fuel for propulsion, relying on the reactive force of burning solid fuel to drive the rocket.
Solid fuel, as a rocket propulsion force, is quite outdated in my view, because solid fuel itself is quite heavy, which wastes a lot of energy.
With each word, Jiang Zhengqing's confidence became more evident. Clearly, he was very confident in his ideas.
