章 864: Chapter 451: Group 2 Design Sets Sights on Fifth-Generation Fighter Jets!_3

The Aviation Group's evaluation of the Kunlun Group 2 engine design took over two months, nearly three, almost as long as it took for the Kunlun Group 2 to complete the design.

There was no helping it.

Some designs were simple for Zhao Yi, such as the turbine assembly, compressor boosting blades, and stator blades; he finished them in just a few days. But, the fact is, it's not just completing the design that's difficult—even evaluating the designs is challenging. Each blade design is incredibly complex, and demonstrating how the design performance translates to engine performance is an exceedingly intricate task.

If one knows how to perform the calculations, that's one thing; but some don't even know how to start. Zhao Yi had to give detailed explanations, allowing the expert evaluation team to understand and proceed with the verification calculations.
