Zhao Yi frowned and asked, "We can first manufacture a prototype, and after it is adjusted well, if there is a difference in performance, we can make fine adjustments to the J-31's design or correct the engine's performance."
Li Jianmin thought about it and nodded, "This is also feasible, but I still have to discuss the general parameters with others when I return, and communicate with other departments..."
He went on and on about it.
Zhao Yi listened for a long time and then asked straightforwardly, "Professor Li, about how much time will it take?"
"...A few months, I guess!"
Zhao Yi frowned again, "Can't it be shorter?" A few months seemed too long; a prototype couldn't be produced overnight. Just setting the parameters would take several months, with all that time wasted in waiting.
Li Jianming shook his head apologetically.
The two didn't come to an agreement.
