Principal Zheng contacted Jiang Yan Hai directly and told him that his application had been approved. Jiang Yan Hai did not need to worry about his classes; his main task was to go to the airfield every night to fly the J10S Azure Dragon and thoroughly finalize all of its data.
Now that it had been approved, things became simple. Jiang Yan Hai immediately entered an extremely busy routine. He attended classes during the day, and whenever he had no classes, he worked directly on engine design.
He first made sure he thoroughly understood the Phantom Engine's design process, then redrew the engine's design from scratch. Er Dan had provided all the relevant engineering software for Jiang Yan Hai, so he did not download professional drafting software from foreign companies.
Speaking of which, China was severely lacking in industrial drafting software. At present, most of what was used came from overseas.
Setting that aside, every night he headed to the Air Force Base to fly the J10S Azure Dragon.
He started at seven in the evening and flew until the early hours of the morning, keeping his daily sleep time at four hours.
Wu Zhenjiang was somewhat dumbfounded when he received the order. This was truly ruthless. Pilots had limited daily flight training time. Even in the United States, which had the highest average annual flight hours, elite pilots trained for only around 250 to 300 hours a year.
That averaged to less than an hour a day. If calculated according to an eight-hour workday, 300 hours could be reached in little more than a month.
Ordinary American pilots maintained around 150 training hours per year, while the Russians behind them also had roughly 150 hours of flight training.
However, ordinary Russian pilots might have even fewer hours. That was
