Two days later, Shen Huan and the others were dragged to Zhuhai by the enthusiastic Chief Tang Weiwen to visit the second Zhuhai International Aviation and Aerospace Expo.
Of course, what is the key model, Chief Tang Weiwen did not reveal it to Shen Huan, but Shen Huan already knew what key models Xifei brought at the second Zhuhai Air Show.
It is a fighter-7 fighter-bomber nicknamed the Flying Leopard, and of course, although the Flying Leopard performed at the air show was designed by the 603 Institute and produced by the West Flight, but now it belongs to the test flight institute.
The chief designer of the Flying Leopard fighter-bomber was none other than Tang Weiwen, so it coincided with the opening of the second Zhu Haihang Exhibition, and a new fighter-bomber designed by him went to participate in the air show, how could he not pull Shen Huan and them to Zhu Hai to see the style of the fighter he designed!
The Flying Leopard fighter-bomber had already flown to Zhuhai a few days ago.
On the day Shen Huan and the others came to fly west, they were in the Yan Liang test flight yard not far from the west flight.
A Flying Leopard fighter-bomber with the words "China Flight Test Research Institute" sprayed on its fuselage is ready to fly to Zhuhai, thousands of miles away.
The Jianh-7 "Flying Leopard" fighter-bomber is China's first completely self-designed fighter-bomber, with Tang Weiwen as the chief engineer, the 603 Institute undertakes the design task, and the Xifei undertakes the production task.
The fate of this flying leopard in the air is also very bumpy.
First of all, we must start from the background of its birth, in the Xisha operation in the mid-70s, the navy found that it could not obtain air support from naval aviation there, so it proposed to develop a fighter-bomber, after all, at this time, the bombardment five and six can be said to have no self-defense capability, so there is an urgent need for a fighter-bomber that has both a certain air combat capability and a powerful sea attack capability.
Almost at the same time, the Air Force also put forward a request for the development of a medium fighter-bomber.
It's just that the requirements of the Navy and the Air Force are not the same, and in some aspects of performance, the requirements put forward by the two units are different, because the development plan of this medium fighter-bomber has been delayed until the 80s.
At that time, Flying Leopard also had a strong competitor, that is, the 650 Institute's strong 6 strong fighter program, and the 601 J-8 program.
Of course, the first to be eliminated is the J-8 program, in fact, the J-8 mainly borrowed some of the technology of the MiG-23, but because of the turbojet seven engine it used, the thrust is small and the fuel consumption is large, especially at low altitude, so the original high-altitude and high-speed fighter is changed to a low-altitude combat fighter-bomb aircraft, and the risk can be imagined.
The strong six is a kind of fighter bomber with a variable swept wing, in fact, it is also developed on the basis of the MiG-23, of course, the strong six did not completely imitate the MiG-23, but carried out a large range of technical optimization, for example, the air intakes on both sides are changed to the belly air intake, so as to be more suitable for the air intake problem when flying at a large elevation angle, the vertical tail and the flat tail are similar to the MiG, therefore, in terms of aerodynamic design, it is more like a combination of the MiG-23 and the F16 fighter of the United States.
Due to the overweight and the disconnection of the supporting turbofan six engine, the strong six also lost to the J-7.
On the contrary, the J-7 was completely developed by itself, and it did not borrow from other models, but it was a completely designed and developed model.
Due to the fact that in the seventies, China purchased fifty finished Spey Mk202 engines from the British Rolls-Royce company, and also obtained a production license agreement for the full introduction of the engine, and the domestic version of Spey was named the turbofan nine "Qinling" engine.
In this way, in the development process of the J-7, there is no core power problem, so in terms of development progress, it is ahead of the Qiang-6 fighter in an all-round way, and in terms of performance, it is also better than the Qiang-6.
It's just that Shen Huan also knows that up to now, the turbofan 9 has not yet been localized, so although the J-7 made its first successful flight in eight or eight years, it has not yet been equipped in batches.
Even before the mass production of the turbofan 9, its number was only about 20 aircraft, after all, only 50 Spey engines were imported at that time.
This time, Shen Huan also enjoyed a benefit, that is, Zhu Hai who arrived by plane.
Speaking of which, this is the first time Shen Huan has taken a plane since he was reborn.
Xifei directly chartered a regional airliner, which is the Yun-7 200A twin-engine turboprop regional airliner produced by Xifei.
As soon as he got on the plane, Chief Engineer Tang Weiwen proudly introduced: "Mr.
Fu, Shen Gong, Forestry Gong, today we will take a regional airliner produced by ourselves and fly to Zhuhai."
This Y-7 200A regional airliner is a new generation of regional airliner that our 603 Institute has in order to meet the needs of the regional airliner market in the next ten years, and you can rest assured of its safety!
” said that Chief Master Tang Weiwen also laughed, and everyone couldn't help laughing together.
Fu suggested jokingly: "Master Tang, the lives of our people will be in your hands!"
” Because Yunqi 200A is also the chief designer of Chief Tang Weiwen, it is also very appropriate for Fu Jianshe to say this.
Chief Master Tang Weiwen smiled: "Don't worry!
Our Yun-7 series regional airliners, although they are turboprops, look relatively backward, but the safety is higher than those jet regional airliners, of course, in terms of comfort may still be slightly inferior.
If I'm not mistaken, by the end of last year, we had delivered 130 Y-7 series regional airliners, accumulating nearly 600,000 hours of safe flight on more than 100 routes at home and abroad, and there has never been a grade accident caused by design and manufacturing problems for more than 10 years.
So if something happens to us this time, it will really be even smaller than the chance of winning the lottery!
” Of course, Shen Huan has nothing to worry about in terms of safety, because it uses the PW127C turboprop engine imported from abroad, which is a product of the United States and was later applied to the MA700 regional airliner.
So Shen Huan also took over and said: "I have bought a lottery ticket for many years, I have never won the lottery, I believe I will not win the lottery this time, I still rely on our domestic regional airliner very much."
If we don't dare to sit on our own, then how can we sell it?
” Everyone laughed, and the atmosphere in the cabin was pleasant.
As the pilot started the engine, the propeller spun rapidly, and the noise in the cabin became louder, and it has to be said that in terms of comfort, the turboprop airliner still can't compare with the jet airliner.
However, the Yunqi 200A type is also not bad, it has reached 60 passengers, the cabin height is 1.9 meters, except for those tall basketball players who come up to bend and walk, ordinary people still have no problem, in the case of full seats, its range can also reach 1,600 kilometers, which can meet the vast majority of domestic regional flight requirements.
This time to Zhuhai is also a direct flight, no need to stop halfway, the distance of the route is 1,300 kilometers, just within the range of the Yun-7 200A.
