On the big screen in the center, the tail of the J-15, which was originally quietly parked on the test rail, began to ignite and glide along the bullet ray at high speed. Pen "Fun" Pavilion www.biquge.info

Everyone held their breath, and only the data that showed the status of the system in real time was constantly refreshing.

"Stable electromagnetic output power!"

The first one was a success! The personnel of the control center invariably exhaled a long breath, and the data showed that the J-15 successfully reached the liftoff standard and took off smoothly after taxiing for about 70 meters.

The key to the success of this trial is yet to come.

On the screen, the ground crew ran and led out of the hangar connected to the electromagnetic track, and this was the first time that the field test fighter took off continuously through electromagnetic catapults.

The crowd's breathing became heavy.

System Reset! Airplane accelerates!

Catapult!

The second plane, once again, has successfully lifted into the air!

What are the grades? The time between the take-offs of the two planes is displayed on the screen in real time: 40 seconds!

This achievement has surpassed the best results of the world's steam catapults that have long been used in actual combat.

We've made it!!

There was jubilation in the control center, and the members of the project team couldn't help but shed tears of excitement.

Academician Niu in front of the workbench was also excited, but he did not forget the follow-up work, and when everyone's emotions calmed down, he issued the next instructions, "Check the status of each part again, collect the whole process data, and summarize and compare."

The members of the project team once again entered the selfless work, and the project began to self-test the program, and the previous continuous take-off data began to be summarized and displayed on the main screen.

"The overall self-test of the ejection system has passed! No faults found! ”

"The sub-project self-test has passed! No faults found! ”

Each sentence of the report added a point of joy to the faces of the project team members.

The greater joy comes from the data displayed on the screen: during the previous test, the maximum ejection capacity of the electromagnetic catapult peaked at 120 megajoules; The maximum peak-to-average stress ratio is 1.07.

The ejection power value is very close to the ideal data for the design of the electromagnetic catapult system, and in the last ejection test of a single aircraft, this value did not even exceed 100.

At the same time, the maximum peak-to-average stress ratio of 1.07 is also very good. You must know that the world's only American "Ford" class aircraft carrier officially installed with an electromagnetic catapult system is about 1.05. This little difference can even be explained by the normal fluctuation of the data.

Obviously, the new control program was able to achieve such a reborn performance without replacing the hardware parts. Thinking of this, the eyes of experts from all walks of life couldn't help but aim at Chen Wenhao, who was following Academician Niu.

The cognition of many old experts has been completely subverted in just two days. A young man who has not undergone professional study and training, but writes the most adaptable and expressive electromagnetic system control system. In terms of common sense, the control program is the "brain" of the whole system, and in order to write a suitable program, the writer must not only have superb programming ability, but also have an in-depth understanding of the operating principle and output characteristics of the major components of the whole system. Because of this, it's hard to imagine a single person who can do this work alone, and the control programs used before were all done by multiple people working together.

However, in the conference room of the Navy Building last night, the experts here had in-depth conversations and communication with Chen Wenhao, and they were already impressed by his program skills, and at the same time surprised by his knowledge of electromagnetic components, but these are only paperwork. In today's actual test, the new version of the control program is so strong that the components work stably and play the best function at the same time, which is an important reason for completely impressing these experts.

On the side of the Navy's top leaders, a technical officer is explaining the significance of the data to the leaders.

"The 120 megajoules peak ejection is close to the design ceiling of the system, and the higher this number, the heavier the aircraft model. This value is three percent higher than the current mainstream steam catapult, according to the previous calculation, this output value means that all carrier-based aircraft models in China can be ejected through this electromagnetic catapult. ”

"In addition, the lower the peak-to-average stress ratio, the lower the application of action to the aircraft during ejection and the lower the overload on the pilot. At present, the world's mainstream steam catapult has a value of 1.25 in the optimal state, and it will reach 2.0 in abnormal conditions (such as lack of maintenance in wartime, shock shock, etc.). Taking the steam catapult used on the Nimitz aircraft carrier of the US military as an example, the maximum overload during ejection is close to 6g, but the really useful acceleration is only less than 3g. ”

Our equipment research institute has previously done a project to analyze the fracture mechanics of steam catapults and electromagnetic catapults on the fuselage due to the magnitude of their different peak-to-average stress ratios. The final result is that the stress on the fuselage is reduced, and the life of the fuselage can be increased by 31%. It can effectively reduce the strength and structural requirements of carrier-based aircraft, and it is estimated that the procurement cost can be reduced by more than 25%. ”

Many admirals stood in a circle, looking at the busy scene in the central control area, thoughtful.

A leader asked, "Is it feasible for our existing aircraft carriers to be equipped with catapult systems in the future?" ”

The technical officer replied quickly, "Our Equipment Research Institute has made relevant estimates, and we think that it is very difficult and not cost-effective. There is not much room for transformation of the Liaoning, 001A has basically completed the construction of the hull, if you need to install catapult equipment, you need to remove the sliding deck, or cut the beveled deck, the amount of work is very large. In addition, I don't know about the internal design of 001A, and I don't know if there is room reserved for the electronic equipment required for electromagnetic ejection, and if not, it will be difficult to make room for it later. ”

After a while, another leader asked aloud, "After this test is successful, how far is it from the official equipment?" ”

The technical officer groaned for a while and replied cautiously, "When it can be equipped, we still have to listen to the opinion of the person in charge of the project team." However, the success of this test should be said to have crossed the biggest hurdle in research and development, and the time from formal equipment has been greatly shortened. ”

Commander Mei, who had been silent, spoke, "We must base ourselves on the present and focus on the future. Whether there is this electromagnetic catapult in the future or not, maybe you will decide whether to eat meat or be beaten. Today's test results are very good and encouraging, and if there are no surprises, the debate can be put to rest. Let's go, let's go and say hello to the experts, celebrate the achievement, and let the logistics comrades prepare well, and add a meal today, which can be regarded as a celebration banquet. ”

"Yes, Commander!" Naturally, the cadres of the base listened to the instructions and went straight to the logistics department of the canteen to make arrangements.

Seeing that the test work had been completed, the experts stopped what they were doing, and a group of senior admirals walked towards the expert work area with a smile on their faces.

Today is a big day for the Chinese Navy, which is concentrating on development, and it is even more a good day. (To be continued.) )
