In the process of remodeling, Zhu Qunying even participated in the naval equipment research group, and sailed with the landing ship to carry out the sixth batch of escort missions in the Gulf of Aden, which lasted two and a half months and traveled more than 10,000 nautical miles.
Overcoming many inconveniences, she lived and ate with the officers and men of the navy, went deep into various departments on the ship, learned about the needs of the troops and the situation of equipment, completed various operational records and analysis, and investigated the improvement needs, laying a solid foundation for the improvement and improvement of the ship.
Of course, these efforts have also paid off, and the new dock landing ship won the second prize of the National Science and Technology Progress Award in 2017!
This award is too heavy, and it also shows that the design of the new dock landing ship is very successful.
Shen Huan smiled and said: "You said Researcher Zhu, I've heard of it, I didn't expect her to be the deputy chief engineer, it seems that you will also have a chance in the future, the chief designer will go one step further, isn't it the deputy chief engineer!"
” Lin Miaoyu grinned, "Really?
If there was a day, it would be really great!
But now I feel that the pressure on my body is so great, I am responsible for the design of the carrier-based helicopter hangar system, and I have never been in contact with the dock landing ship, I don't know if it will drag the organization back, alas!
” Shen Huan comforted: "Don't be afraid, don't you have Master Zhu to ask for advice, and besides, I have a strong backing!"
The helicopter hangar is relatively simple, but it should be taken into account that the landing method of carrier-based helicopter is different from that of land-based helicopters, and when landing on a ship, the complex sea breeze movement, as well as the airflow behind the ship's superstructure, will be more complicated, so when designing the hangar, these also need to be taken into account, and the air flow field and movement law in the landing area should be analyzed!
” Lin Miaoyu sighed: "It's so complicated?
I, I'm a little worried. ” Shen Huan smiled: "It's okay, you've been doing it for so many years, isn't the missile boat quite good?"
There are generally three methods to analyze the mutual interference of ship and helicopter flow field, one is the actual ship test measurement, the other is the wind tunnel blowing test, and the third is the numerical simulation of computational fluid dynamics.
The first option is obviously not possible, and the cost of wind tunnel testing is very high, so I suggest that the third method can be considered. ” Shen Huan is also really happy for his wife, and at the same time, he also knows very well that in fact, relatively speaking, being in charge of the subsystem of the helicopter hangar should be the easiest among all the chief designers of the subsystem, which should also take into account that Lin Miaoyu is responsible for the design of a subsystem for the first time.
In the future, there may be another female chief engineer in the team of Chinese ship designers, and Shen Huan is also looking forward to that day!
With the experience in the design of dock landing ships, it is very likely that Lin Miaoyu will participate in the design of amphibious assault ships that are more advanced and have a more important position in the naval equipment sequence in the future, and it is not even difficult to serve as the deputy chief engineer.
Because by that time, Lin Miaoyu also has enough experience and technical ability.
The amphibious assault ship, nicknamed the small flat-topped by military fans, is twice as large as the Type 071 dock landing ship!
Its belly is much larger than that of a dock landing ship, especially since the carrying capacity of helicopters far exceeds that of a dock landing ship.
Of course, the new 20,000-ton dock landing ship to be developed now carries a lot of helicopters, and the hangar width of the new dock landing ship in Shen Huan's memory is more than ten meters, the height is close to six meters, and the length is nearly twenty meters, which is enough to accommodate two straight-eight helicopters, or three straight-nine.
And if necessary, two or three helicopters can be moored on the aft deck, the total helicopter load can reach six, and there is also a usable take-off and landing point, in which case the vertical landing capability of the new dock is also very strong, and it can transport more than a hundred marines at a time.
Therefore, the design of the helicopter hangar system that Lin Miaoyu is responsible for this time is relatively less complicated, but the role is quite large, because one of the most important capabilities of the dock landing ship is vertical landing, and the design of the helicopter hangar is very important, which is related to the carrying capacity and maintenance support capacity of the helicopter.
As a reborn, Shen Huan knows very well that amphibious assault ships are the ultimate goal of China's ocean-going navy, and in an ocean-going navy, in addition to aircraft carriers, amphibious assault ships are the most important core strength.
That's why Shen Huan is looking forward to Lin Miaoyu becoming the female deputy chief engineer of the Chinese Navy's amphibious assault ship in the future, or even the female chief engineer!
Once, the world's first Iwo Jima class equipped by the US Navy in the sixties made Chinese military fans and officers and soldiers of the Chinese Navy drool!
Because the Iwo Jima-class has a direct flight deck and hangar similar to that of an aircraft carrier, and can carry 30 helicopters in addition to being able to carry thousands of marines and large air-cushion landing craft like a dock landing ship?
An amphibious assault ship larger than the aircraft carriers of many countries.
Of course, in the 70s, the United States developed a larger Tarawa-class amphibious assault ship, which is much larger than the Iwo Jima class, with a full load displacement of 40,000 tons, and can carry 45 helicopters, a proper quasi-aircraft carrier.
And then the more advanced Wasp class, not to mention, can also carry vertical take-off and landing fighters.
For the Chinese Navy, amphibious assault ships are also very urgently needed, but it is obviously unrealistic to want to cross the dock landing ship at once and go directly to an amphibious assault ship of 30,000 tons or 40,000 tons.
Therefore, the first step is to develop dock landing ships, which can be regarded as the embodiment of the development strategy of small steps and fast running.
Shen Huan knew that in the next two years, he and Lin Miaoyu might be in a state of gathering less and leaving more.
In fact, even if Lin Miaoyu does not join the dock landing ship design team, Shen Huan himself will be too busy, in addition to the Jiangnan Changxing Shipbuilding Base, the first phase of the project will be completed within three years, and he will participate in a lot of work, as well as the Jiangnan Research Institute, and the Technology Innovation Center, there is also a lot of work waiting for him.
And not long after Lin Miaoyu became the chief designer as she wished, Shen Huan was finally promoted!
This is a double happiness thing, Shen Huan was promoted to deputy director of the technology innovation center!
As soon as this letter of appointment came, Shen Huan knew that he was going to have another treat.
Isn't it, all the young people in the technology innovation center are now taking Shen Huan as an example!
At the age of less than twenty-nine, he became a senior engineer and a middle-level cadre of the Engineering Research Institute of China Shipbuilding Industry Group, which is almost unheard of in the entire Chinese shipbuilding industry.
However, for Shen Huan, these are more pressures and responsibilities, although some salary income has increased, but is Shen Huan a person who eats on wages?
Apparently not!
It's just that with the rise of his position, he can do more for China's shipbuilding industry and play his role.
