After hanging up with Professor Zhao, Jiang Yan Hai could not help pumping his fist. This was fantastic! They had finally built the engine! Although it would still be a long time before it could actually be put into service, it was already far ahead of other engines.
Many tests could be conducted simultaneously, while component tests that other engines needed before assembly could be skipped this time.
Because a private research institute did not need to worry about spending money, directly testing the finished product was naturally more precise than testing individual components.
Especially after the entire engine was started: extended test runs and destructive test runs. Destructive testing was actually simple—it meant testing the engine's limits. For example, turning on afterburner, its maximum-thrust state, and maintaining that state for a long time to see how long the engine could last.
All of those counted as destructive test runs.
They were meant to see how it performed under every sort of extreme condition.
After such limit testing, they only needed to inspect its components again.
Jiang Yan Hai took out his phone and directly contacted Old Liu.
This time, the call was not answered immediately. Someone did pick up on the other end, but merely told Jiang Yan Hai that he would have to wait a while before Old Liu could call him back.
More than half an hour later, Jiang Yan Hai finally received Old Liu's call.
"You brat, calling so late at night. Couldn't you spare a thought for us old folks?" Old Liu joked with a laugh.
"Sorry, Old Liu. I have something to tell you," Jiang Yan Hai immediately apologized.
"All right, I was joking. When you get old, you need less sleep. I haven't rested yet. I was on the phone with someone else
