Chapter 395: Platform
This young man really has a big brain, replacing the turbojet 8 used by the current H-6 with the Soviet D-30KP engine, according to this idea, it is no longer even the same aircraft model, but it sounds like it is feasible.
Replacing the turbojet 8 oil tiger with a mature turbofan engine like the D-30KP can not only be effectively controlled in terms of fuel consumption, but also in terms of thrust.
"I don't know if it's really feasible, but you can start by telling us what makes you think it's feasible."
What is the reason, do you still need a reason for this, Wang Zhengguo almost directly exploded the gorgeous number of the H-6K, this is a model that has been highly recognized by the Navy and Air Force after the upper plane Xifei came out, and all the data are not bad.
Now that I think about it, it seems that there are a lot of reasons, and you can just break it.
"Changing the engine means that the range will increase, and the re-repair will be improved, at least to reach the H-6I level of the four-engine Spey, and with the Il-78 air tanker, this can be called a strategic bomber, what is the military not satisfied with?"
Before the H-6K, including the Republic itself, officials called the H-6 a tactical and campaign bomber, after all, the gap between it and a strategic bomber is still not small.
Equipped with a twin-engine D-30KP H-6, Chief Wen has not seen, but the four-shot Spey H-6I has heard of it, and after comparison, it is found that the two are indeed similar in terms of range, and the H-6I was able to position the H-6 as a strategic bomber, and now the new H-6 equipped with D-30KP engine will definitely not be bad.
Now that it has been said here, Wang Zhengguo doesn't mind having some more brain holes, although this brain hole has not appeared in the upper plane, but the implementation will not be too big a problem.
"Replacing the D-30KP engine, which can greatly enhance the range and airtime of the H-6, means the arrival of a large military jet platform, and we can directly change it into a maritime patrol aircraft, anti-submarine aircraft, and theater/campaign early warning aircraft!"
The maximum take-off weight of the H-6K in the upper plane has reached 90 tons, and the fuel consumption has been effectively controlled, which is not much weaker than platforms like 737/320.
So why can't the H-6 be a special platform, not to mention that now this face is also planning to install air refueling capabilities, and more than 20 Il-78s will be introduced in China, which is absolutely proper in terms of endurance.
After the D-30 is refitted, the maximum flight speed of the H-6 is as high as Mach 0.8, and it can fly faster to the combat airspace; according to the naval combat plan of the Republic for a long time in the future, almost all surface ships patrol in a large area, and air support will be called immediately after the situation is found to be wrong, and then the flight speed of the anti-submarine patrol aircraft will be required.
Using the H-6K platform as an anti-submarine aircraft, the pylons originally used to mount missiles under the wings do not even need to be changed, just hang anti-submarine torpedoes, remove the tail turret and replace it with a magnetic anomaly detection device, close the magazine, and place sonar buoys, what is not satisfied?
Do you want to complain that the size of the fuselage of the H-6 platform is too small to install various large-scale equipment, and the personnel can't use it?
It's funny, the diameter of the h-6 fuselage is 2.5 meters, why can't it install all kinds of personnel and equipment, Embraer's ERJ145 fuselage diameter is only 2.3 meters, and it is still changed to a patrol aircraft and early warning aircraft, and it is very good to use.
And if you take another 10,000 steps back, even if the military still thinks that the H-6 body is not enough, that's good!
Lengthen the fuselage, anyway, the maximum take-off weight of the H-6K after replacing the D-30KP has increased significantly, so it is enough to lengthen the fuselage directly on the basis of the original H-6.
In addition to anti-submarine patrol aircraft, small campaign tactical/campaign early warning aircraft can use the platform, anyway, it is much better than the Yun-8 series in many places, and the Yun-9 project was also cut off as soon as possible, so that Shaanxi Fei can free up time and energy to engage in a new generation of tactical transport aircraft.
This is a lot of balabala, although there is a lot to say, but Mr. Wen thinks about it carefully but feels that it is very necessary, and if you really want to follow what Wang Zhengguo said, you can think that this must be another big project.
Since it is a big project, and now it just sounds reliable, Mr. Wen is a little strange, with the current urine nature of the southwest motive, he will really let go of the project, why not compete for the engine of the six major changes?
"Your plan sounds feasible, but why choose the D-30KP engine, now the Qingcheng engine should also be able to meet the requirements of use, do you really change sex, and you can't change to a vegetarian diet?"
Now Southwest Motor has completed the full localization of Qingcheng engine, the design team has taken shape, saying that to remove the afterburner of Qingcheng, and then increase the bypass ratio, it should be possible to make a relatively reliable engine, reaching 12 tons of thrust will not be too much of a problem.
It seems that Southwest Motive really has the capital to compete with the D-30KP.
However, there is a problem that must be clarified first, all of the D-30KP can be used to replace the turbojet 8, because this engine has a bypass ratio of only 2.4 and a maximum diameter of only 1.5 meters.
In terms of diameter, the original turbojet 8 of the H-6 is 1.4 meters, so the engine compartment can be replaced with each other after minor modifications.
The air flow rate of D-30KP is 240KG/S, and the turbojet 8 is 162KG/S, the gap between the two is not too big.
But what will happen if it is replaced by a non-afterburner turbofan with a Qingcheng engine? In fact, a horizontal comparison of the CFM-56 of the same level of military and civilian promotion, you can see the gap at a glance.
The average thrust of the CFM-56 family is 10-11 tons, but the bypass ratio reaches 6, the air flow is about 350KG/S, and the engine diameter is as high as 1.7 meters.
Compared with the military afterburner turbofan engine D-30KP-F6 in the D-30 series family, this engine has a thrust of up to 15 tons, which is not at the same level as Qingcheng and F-110, how can it be compared?
In this way, how can Qingcheng be used for turbojet 8 engine replacement without afterburner, if it is really forced to be launched, I am afraid that the H-6 will hurt the muscles and bones, so it is not cost-effective overall.
Moreover, now Southwest Engine itself is barely realizing the national production of Qingcheng engine, and it can be prepared to replace some cold-end parts for the engine and improve the thrust-to-weight ratio of the engine, but to say that the engine has been completely overhauled, and the non-afterburner turbofan with a bypass ratio of more than 5 is still to save it first!
The whole design concept is to use mature shelf products to quickly launch the aircraft, rather than slowly waiting for the southwest to tinker with the domestic engine, and the two time nodes are absolutely incompatible.
There are not too many aircraft models that have been pitted by engines in China, and now Xifei is counting on the new H-6 to continue the production line, in case the southwest motive can't keep up with the progress, then it will really become a sinner, and it will definitely take the Xifei side out of the pit, and don't think about cooperation or anything in the future.
