"The engine runs fine!" the tester replied.

""

This time, the sand swallowing test of the engine lasted for half an hour before stopping. During this period, the density and particle size of the sand were repeatedly increased, and it finally turned into small pebbles one or two millimeters in diameter.

, but this engine persisted.

After the sand swallowing experiment stopped, the engine on the No. 1 test bench did not stop running, but continued the durability test, and during the 500 hours of this test run, the five engines on the test bench will continue to run.

Various experiments continued from time to time.

"The No. 2 test bench is ready for the ice swallowing test." After recording various data of the No. 1 engine, Xiang Juncai was ready to test the No. 2 engine, and this time it was different from the sand swallowing test of the No. 1 engine.

This time, we are preparing to conduct an ice swallowing test on the No. 2 engine.

"Yes! It's ready!" the tester replied.

"Start testing!" Xiang Juncai ordered.

At the same time, the test driver also pressed the button on the console. Suddenly in the control room, Qin Chu could see some crushed ice spraying out from the console and being sucked into the engine.

This made Xiang Juncai a little nervous. After all, the bad ice and snow weather had already begun to be simulated in the second console at this time. A large amount of crushed ice and snow water were sucked into the engine, which would affect the engine.

Fortunately, the engine they designed is a pulse engine with no rotors and blades inside, so there is no need to worry about damage to the blades due to the entry of broken ice and impact on the blades.

Of course, this is only theoretical and will not affect the engine, but this is only theoretical, and it will only be known through testing.

This ice-swallowing test also lasted for half an hour, and the ice-swallowing test did not stop until half an hour later.

Subsequently, the engines on other test benches also underwent other tests, such as simulating bird impacts, foreign object inhalation, etc. However, the engine condition was maintained very well and there were no unexpected incidents at all.

Just when Xiang Juncai and the others were conducting endurance and ice and sand swallowing tests on the engine, Zhang Yi's phone rang in the office. When Zhang Yi looked at the caller ID, it turned out that the person calling this time was Mr. Huang.

Come.

"Grandpa! Hello! What do you want from me?" Zhang Yi asked. Zhang Yi knew that generally speaking, Huang Xiru's grandfather would not call him easily if there was nothing important.

"Xiao Yi! I heard that your Qicaishi Group's national project for a new engine has been greatly hindered. I don't know if it is true." Mr. Huang asked.

Although this matter has caused great controversy among the high-level officials of the Dahua Empire, it is limited to the aviation department, and Mr. Huang has been staying in the Hangcheng Military Region during this period, so the details are not very clear.

"Yes! Grandpa! Our Qicaishi Group's engine has indeed encountered very big obstacles in the national project approval." Zhang Yi replied.

"Do you want my help?" After hearing Zhang Yi's words, Huang Xiru's grandfather did not answer immediately. It was only a few minutes after he came over that his words came out on the phone.

Zhang Yi had no doubts about Mr. Huang's ability to help Zhang Yi and his Colorful Stone Group in this matter, but Zhang Yi was not prepared to let Mr. Huang intervene.

After all, as Huang Xiru's grandfather, and Zhang Yi is Huang Xiru's man, Huang Xiru's grandfather has always maintained a neutral attitude in this incident and has not expressed any opinions.

"Grandpa, I have great confidence in this engine of our company, and our company is not short of money. If there is really no way to establish a national project, then our company will continue to develop this type of engine, so please

Grandpa, don’t worry, not to mention that there is no final conclusion yet on the national project. I think the top management of our Dahua Empire will definitely make a wise choice and will not give up an absolutely excellent engine because of the interests of some people.

"Yes." Zhang Yi said.

Then Zhang Yi and Mr. Huang chatted for a long time, and during the chat, Zhang Yi made it clear that Mr. Huang did not need to take action in this matter, and also made it clear that this engine would be installed in their Colorful Stone Group in the future.

The aircraft developed will not appear on other types of aircraft produced locally.

Of course, Mr. Huang disagreed with Zhang Yi's statement. After all, a good engine can greatly improve the performance of an aircraft. If the country establishes the project, the military will never give up on other projects.

This engine is installed on the aircraft.

"Grandpa! If this engine is successfully developed, it's not that I don't want to install it on other aircraft, but installing it on other aircraft will be a waste of the performance of this engine. It is the most powerful engine in our country."

The same goes for the advanced No. 20 aircraft. After all, the maximum thrust of this engine can allow the aircraft to fly at supersonic speeds of 6 times the speed of sound, and none of the existing aircraft in our Dahua Empire can withstand such speeds.

What's more, the aeroengine developed by our Colorful Stone Group is more than five meters long, and the overall diameter is nearly one meter. It cannot be installed on the existing aircraft of our Dahua Empire, so even if I want to use the existing aircraft

There is no way to modify the aircraft." Zhang Yi shrugged and said.

"This! Okay! I will no longer be involved in Xiaoyi's matter, but Xiaoyi, do you know when your group will be able to develop its own aircraft?" Mr. Huang asked.

"Grandpa! At present, our group's base in Daxi Province has begun design work in this area, and the general frame of the aircraft has also been designed. If nothing unexpected happens, then our Qicaishi Group's first prototype

It should come out next year," Zhang Yi said.

"Okay! Then Xiaoyi, I'm waiting for your good news, and our country is also waiting for your good news." Mr. Huang said.

After the two chatted for a while, Mr. Huang hung up the phone.

Zhang Yi originally thought that the old man would ask about the data performance of the aircraft designed by his group, but until the old man hung up the phone, he never asked about the data performance of the aircraft his group was designing.

Zhang Yi knew that the reason why the old man didn't believe that the Qicai Stone Group was not capable of developing his own aircraft next year was because he didn't want to put more pressure on him. After all, the Qicai Stone Group had failed to establish a project for this engine.

It has been under great pressure. If it were not for the strong capital of the Qicai Stone Group, it would definitely give up this project. Neither the old man nor the military hopes that the Qicai Stone Group will give up the development of this engine.
Chapter completed!
