The team leader, Yuan Haitao, and two engineers, Zhou Qing and Xue Fengge, spent most of their time in the office, discussing Zhao Yi's improvements to the engine. By now, it was clear to them that Zhao Yi was intent on completely overhauling the prototype, from inside out.
If it were before coming to the capital, they would never have believed that a single person would be capable of such a task. An individual's abilities are limited, and the structure of an aero-engine is too complicated. Being able to design a single component is already quite remarkable, let alone implementing improvements from the inside out.
Now they believe Zhao Yi is capable, but the specific effects are hard to predict.
Zhao Yi's abilities are indeed commendable, but the performance of an engine is not solely confined to the design, hard technologies like the raw materials for the turbine blades are also critical factors.
