Chapter 632: Feibao's positioning

In this era, mid-air penetration is to find death. Only when fighters penetrate from ultra-low altitude can they have the possibility of successful bombing. Otherwise, they will be shot down by the opponent's air defense missiles.
However, ultra-low-altitude penetration requires terrain tracking capabilities. Simply put, it requires the radar to have a synthetic aperture mode that can conduct terrain mapping. On the radar screen, the shape of the ground can be displayed so that the pilot can better operate the aircraft. If the aircraft is operated by telex, it can also be linked with the operating system to avoid in advance.
Without these, relying on the pilot's own technology would be dangerous.
Now, Han’s radar technology is advancing, but it’s enough for 114 schools to be busy with the air-to-air modes. If you want to have a ground-based surveying and mapping mode, it may take several years. time.
However, the Navy’s needs are simple.
Because the sea surface is flat, there is a wind wave, that is, one or two meters is quite high, so there is no need to have automatic avoidance, there is a radar altimeter and automatic stabilization to control the height of the sea. Worse than Boom Six?
In the needs of the Navy, it is just a missile carrier with a long endurance capability.
Therefore, the needs of the Navy can be the first to be realized. At the same time, the Navy has also taken the lead in equipping the H-7 fighters, which also laid a risk for the Air Force.
In later generations, you can see that the flying leopard crashed seriously.
Why?
The Spey engine is mature and reliable, so there is no problem with the Feibao engine. The problem is its aerodynamic design.
Everything is about stability.
The wing of the H-7 has no leading edge flaps, (that is, the leading edge of the wing can be deflected downward) is not particularly suitable for low-altitude and high-speed penetration.
For airplanes, the biggest role of leading edge is to increase the lift of the airplane. Since the large-scale application of jet aircraft, leading edge have become an indispensable part of jet aircraft wings. If the aircraft does not have leading edge flaps, the feedback that the aircraft can provide to the pilot before the wing stalls is not obvious. , Which caused a lot of trouble to the pilot.
The Navy’s flying leopards are mainly mid-to-high altitudes and rarely enter low-altitudes. Therefore, if there is such a thing, there is not much reaction, but it is different to the air force. The air force is to fly at low altitudes and drill ravines. When the wing suddenly stalled, the airplane lacked response.
In this way, the pilot cannot operate, and at the same time, because the problem occurs at low altitude, once the wing stalls, the pilot's escape window is very narrow.
At that time, it was limited by technology. After all, Han's technology for adding leading edge to wings was not mastered until the F-7E was developed in 1992, so the R&D staff at that time could only choose to cancel the leading edge to reduce the risk of research and development. .
But now, with the help of Qin Guan, the new J-7 already has this thing, and relying on the advancement of precision processing technology, there is no reliability problem.
Therefore, it is not difficult to add to it with excellent low-altitude performance.
But these are all things to do. Now, let’s rely on the Navy’s capital investment to get it out.
"We have made breakthroughs in many technologies. For example, our radar has begun to manufacture advanced pulse Doppler radars with flat slot antennas." Qin Guan said: "Our technicians have also begun to adopt the same The 1553B data bus technology, so I suggest that you can learn from 6611, refer to the development of existing technology in our country, and strive to improve the performance of the aircraft."
As the first self-developed advanced fighter in Han, the airborne equipment of the H-7 has been greatly increased.
For example, the historical H7 contained 232H monopulse multifunctional fire control radar, ZJ-9 commander, 210 Doppler navigation radar, 265A radar altimeter, HZX-5 heading and attitude system, etc., of which 232H fire control Radar is the key to naval operations.
Due to the increase in avionics equipment, the traditional hardware interconnection method is no longer suitable for use on the JH-7 fighter, so it uses a data bus to connect the systems to form a preliminary integrated avionics system. Compared with the 1553B data bus, it uses the low-speed, one-way ARINC-429 bus. The system uses the fire control computing center to be responsible for the cockpit display.
The current Hongqi certainly wants to adopt this method, but we have completed the research and development of the 1553B data bus, which has already been adopted on the Raptors. Therefore, simply let the electronic system of the Hongqi be upgraded in advance. .
"It's great, we can go and take a look." Old Chen said, "The progress of the 6611 Institute over the past year is so enviable."
How can you not be envious? In a year's time, the advanced three generations of aircraft have already been made to fly for the first time. This kind of progress is quite fast.
In contrast, after so many years of development for our own Hongqi, it has only built a wooden prototype, which is more annoying than people.
"Yes, our H7 also has to speed up research and development." Qin Guan said: "After all, this is our advanced fighter-bomber."
Hearing Qin Guan's words, Old Chen's face couldn't be happy: "Mr. Qin, this aircraft is in an embarrassing position now."
They have been recognized by the Ministry of Aviation Industry and have been designated by the Navy as the most urgent project, but too much has happened recently.
For example, regarding the introduction of Tomcats.
All of a sudden, it was necessary to pack and buy nearly eighty Tomcats, and at the same time, to copy them at the 6650 Research Institute. The speech of President Qin at the meeting that day was very clear. Tomcats will not only become a special system. The air fighter will transform into a terrible fighter-bomber with variable swept wings.
In this way, wouldn't this one of his own party become a tasteless one? They are all equipped with Speys, and they are all dual-engined. At the same time, their own aircraft has no air combat capability. Even if the Tomcat transforms into a bomb cat, its air combat capability is also very powerful.
Mr. Chen has always been worried about whether his project will be squeezed out?
Qin Guan knew what he was worried about when he heard what Old Chen said.
Now, the positioning of Hongqi has become blurred.
As a specialized bomber, the Tomcat has the same amount of ammunition as it, and as a fighter, its air combat capability is very poor, so no matter how it compares, it seems that there is no need for the H-7.
This is definitely more headache for Old Chen than sitting side by side. This is what he has been worried about since he returned to the capital.
"Old Chen, don't worry, this aircraft also has advantages, it is cheap!"
Qin Guan got to the point at once, what are the advantages of Flying Leopard? It's cheap!
