Chapter 629: Boom-7

"We increase the front turbine temperature of the engine, which will bring about other changes. Therefore, we must consider comprehensively. A small parameter change means that we must re-research." A Rolls-Royce company An expert in said: "We need to conduct detailed research and bench test runs. These are best carried out in our Rolls-Royce company."
"If it is carried out with us, the cost of these test runs will be borne by ourselves. However, if we go to the Rolls-Royce company for test runs, then I am afraid that our superiors will not give funds." Facing Rolls-Royce. Mr. Wu said with a smile on the expert’s proposal.
After the last negotiation, Mr. Wu also had confidence. With foreigners, he had to be hard-hearted when it was time to be hard-headed. It was impossible for them to avoid their own research.
Through the modification of the engine, the rapid accumulation of research and development experience is what they need most. Now, it is a golden opportunity.
"But the equipment here is not enough."
"We can buy."
"I think we can experiment here." Another Rolls-Royce expert spoke. It was Robert, an engineer from Rolls-Royce, who was very friendly to Han.
Now, upon hearing his words, the Han people present showed a smile.
"In our modification of Spey, the improvement of the compressor was proposed by the Chinese side. After calculations, we can fully meet the requirements of increasing air flow and meet their processing basis. Now, we are testing here and also There is no problem. After all, Spey’s prototype has already completed the bench test here."
The engineer from Rolls-Royce, who had just opposed it, stopped talking.
In order to remodel Spey, the engineers of Rolls-Royce Company wanted to give a high level of guidance. As a result, the Han people actually came up with a detailed plan for improving the compressor. After a calculation, it was completely correct.
By improving the compressor, increasing the air flow, improving the turbine blades, and increasing the front temperature of the turbine, you can inject more fuel and explode more power.
The modification of this engine, theoretically, has been studied, and it is waiting for the final installation experiment.
After all, no matter how good the theoretical research is, there will be many problems in the experiment. Now, they want to keep a hand in the experiment and bring it back to the country to test the bench.
Of course, Han will not agree.
"It seems that our progress is pretty good." At this time, Qin Guan came in with a smile: "Our new JF, maybe it can wait for the new engine during the test flight."
Spey’s current thrust of more than nine tons is unsatisfactory for the new JJ. If the modification is increased to 11.5 tons, or even 12 tons, it is roughly enough. If you rely on the agility of the canard, it will let you The Raptors fly more smoothly.
If the new JJ is flying for a test flight, it is best to use the new engine, but the reliability must be achieved, otherwise, the old model should be used to ensure that it does not malfunction.
"Yes, President Qin, we also look forward to catching up with the new engine. However, our old engine will not be wasted. Now, the old engine has been used in our H-7."
Hearing what Elder Wu said, Qin Guan was taken aback for a moment. Yes, he had forgotten such a project.
H-7, this name may be unfamiliar to most people, but when it comes to Feibao, it is definitely the famous, the first long-range aircraft in Han, that is Feibao.
Flying Leopard is H-7, and the current project code is H-7, also known as Project 70.
Qin Guan was immediately excited. This project started when Qin Guan was not involved in the construction of the military industry.
In early 1973, the Aviation Research Institute of the National Defense Science and Technology Commission of Han State instructed the 6603 Research Institute to carry out pre-research on supersonic tactical bombers. The aviation development planning preparatory meeting held in the capital in April 1973 pointed out: to build a H-5 or H-5 and Qiang-5 common successor to strengthen the air attack force.
The H-5 and H-6 are too slow to meet the requirements of modern high-intensity combat, while the supersonic Strong-5 has a short range of only 1,500 kilometers, and its ammunition capacity is only 2,000 kg. Therefore, the demand for this new type of aircraft with both fighter and bomber performance is urgent.
As a result, in 1974, the 6603 Institute established the H-7 program demonstration team and went to the air and naval forces to conduct investigations and studies.
At this moment, a battle broke out between the Han Navy and the monkeys in the southern waters.
Relying on the fearless spirit of the brave, the Chinese Navy sank one Monkey Navy gunboat and wounded three destroyers, but it also exposed the problem of lack of aviation air support.
Therefore, the needs of the Navy have become more urgent.
Therefore, under this situation, the Commission of Science, Technology and Industry for National Defense determined the tactical and technical requirements for the new fighter bomber based on the requirements of the navy and air force. The needs of the Air Force. In the plan, the navy and air force's new annihilation bombings are basically the same in technical performance except for the weapons and equipment used in combat.
The R&D of the H-7 was launched vigorously.
On October 10, 1977, the Ministry of Three Machines issued (77) Sanji No. 1008 "Approval of the Model Name and Code Name of the H5 Successor" and officially named it H-7, code H-7.
Next, the preliminary design of the H-7 after the improved plan proposed by 6603: a fighter-bomber with front-line supersonic low-altitude penetration capability, determined a way to combine traditional design and wire-by-wire flight control technology, and tried to make this design To reach a more advanced level, and this aircraft uses the Spey engine.
On the whole, the H-7 has a simple structure, a simple aerodynamic design, a large ammunition carrying capacity, and a long combat radius. After that, after many years of ups and downs, it finally entered the naval force, entered the air force, and became a member of the Han nation. An excellent fighter bomber.
After Qin Guan came to this world, he focused his energy on fighter jets. After all, the biggest threat of Han was the bombers of Xiong State. For a long time, Qin Guan had not paid attention to this soaring flying leopard.
The 4430 factory is here to imitate Spey, and at the same time, this factory is also a subordinate unit of the 6603 Institute. Now that Mr. Wu said this, Qin Guan is also interested: "It seems that I am going to visit the 6603 Institute. ."
In fact, due to limited time and energy, Qin Guan could not focus on all of his projects alone, which was beyond his authority. For similar projects such as Yunshi, helicopters, etc., although Qin Guan wanted to participate, he was still powerless. of.
