In the early years, there was the British Marconi Company, which was the first Western aviation manufacturing giant to cooperate with AVIC Southwest, and the cooperation was airborne avionics and radar at that time; This was followed by the scattered stragglers on the German side who had contact with AVIC Southwest China, and later it was unified into the German MM Company, and the cooperation between China and Germany was relatively early, which was all-round, multi-field and deep-level; There is no need to say anything more about the other American Northrop, Grumman, and Embraer.

Or the problem of the German MM company, the history of cooperation between the German MM and AVIC Southwest can be regarded as a long-standing model, and the current MPC-75 passenger aircraft has successfully blossomed and borne fruit, and the investment of both sides will be fully recovered immediately, and the later stage is ready to make a profit and count the money; The CG-2000 engine has also entered the maturity period of an aero engine at this time, and it is just at the best stage of the bathtub curve.

Even at this time, Bombardier has begun to contact United Airliners, for the CG-2000 series engines in the field of medium-thrust turbofan engines, Bombardier has been completely convinced, knowing that this engine is tailored for the MPC-75 by both China and Germany, but still have the cheekiness to ask if it is possible to provide a power system for the CRJ-700.

Fortunately, the United Passenger Aircraft Company and the United Aero Engine Company are at the same level, and neither side is qualified to force the other to do anything, so the MPC-75 aircraft manufacturer has no way to take the CG-2000 engine manufacturer.

The German side did not express any objection to whether to sell the engine to the CRJ-700 passenger aircraft, and they still had some uncertainties in their hearts, so in the end, it was decided by United Aero Engines: the engine could be sold to the CRJ-700 under development by Bombardier, but in view of the thrust requirements of the CRJ-700, the thrust of the CG-2000 engine was still a little too redundant, so a CG-2000-1- model was launched. The maximum thrust of the engine was reduced to 6.5 tons.

CG-2000 series engine unique gear transmission technology is too dick, by the majority of airlines sought after is also no way to do things, at this time, the entire CG-2000 engine is finally a series of engine family looks, just for this matter, 0112 also set up a CG-2000 engine project department, the follow-up is responsible for the improvement and upgrade of the CG-2000 engine service.

Some people are happy and some people are worried, the MS-4 engine as a small thrust turbofan developed for Embraer's EMB-145 passenger aircraft, but at this time it seems a little tepid, it seems that the follow-up improvement should be limited by the use of the engine, and the potential for development may not be too great.

However, the MS-4 turbofan engine with the small thrust turbofan engine core machine performed well, not only used in the MZ-2200 turboshaft, but also may be used in the future may even be used in the new military small thrust afterburner turbofan engine, a few years ago Iran talked about the magic F-5 fighter although it was given up because of the sudden special reasons at that time, but then the Northeast of AVIC seems to be mixed with Iran, as for how to continue to develop, this is not very clear.

I only know that now the turbo alliance company under AVIC Northeast is still continuing to produce the turbofan 10 engine transferred by AVIC Southwest technology ten years ago, but it seems that the turbofan 10 engine in the northeast is continuing to change the magic, although the thrust of the engine has not increased, and has been maintained at the maximum thrust of 7 tons, but the thrust-to-weight ratio data is constantly optimized, and now it is said that the turbofan 10c engine in the plan has been fast to the thrust ratio of 8.

What Yang Hui didn't know was that the reason why Iran's cooperation did not involve AVIC Southwest was because the turbofan 10C engine in the northeast of AVIC moved Iran and made Iran see the hope of an Iranian version of the F-20 Tiger Shark fighter, so there was really nothing to do with AVIC Southwest in the future.

Talking too much, and then back to the issue of cooperation between AVIC Southwest and Germany, this cannot avoid Germany's "self-developed" C-320 large jet front-line tactical transport aircraft, in this project, AVIC Southwest has played an extremely important role behind the scenes, starting from the entire C-320 transport aircraft project, which has been two years.

According to the requirements of the project design, the C-320 transport aircraft was required to develop the speed of development, so the fuselage design of the An-70 was used, and even the general wing was inherited from the supercritical wing shape of the An-70.

In addition, AVIC Southwest has sent a technical support team directly stationed in the design headquarters of MM company in Germany to provide comprehensive technical support for the problems encountered in the design of C-320, according to the feedback information of technical personnel in Germany, the entire design team is now directly arranged into the C-320 development team, and they do not have any technical support, directly as a technical backbone.

But Germany's technology does have something worth admitting, such as the prototype manufacturing of the entire aircraft, the German technicians in the manufacture of the prototype, the modern processing and manufacturing capabilities of the technicians are quite amazing, all of them are used for auxiliary processing and manufacturing, and the follow-up assembly process is also not bad, and the prototype of the factory even gives people a kind of aircraft that is finalized and delivered.

In fact, then again, with the completion of the processing and manufacturing of the prototype of the C-320 transport aircraft, the first prototype was ruthlessly tied to the gallows after taking pictures.

It was not until the second prototype was manufactured that the southwest side of AVIC received the news about the C-320 transport aircraft again, according to the planned progress, the first flight test of the C-320 transport aircraft will be carried out in the second half of 96, but Yang Hui will miss this first flight, after all, the face of the Germans still has to be taken care of, the reason why the MM company is so hard, it is to blow out the cowhide very early, C-320 must be a large military transport aircraft independently developed by Germany, Therefore, during the first flight, even the technical team sent by AVIC Southwest had to avoid it for the time being.

But these don't matter, as long as the Germans can do things in accordance with the requirements of the contract between the two parties, and give AVIC Southwest the same amount of things to AVIC Southwest, the rest doesn't matter, anyway, the situation is like that, it's not a big deal, AVIC Southwest makes the first flight of the new plane every year Yang Hui is annoyed.

"Okay, we know the news about the C-320, and we don't bother to take the time to go so far to Germany, our top priority now is to do a good job of this defense exhibition as soon as possible, and to meet the needs of the army and the country, this is the main task of our national defense industry, and no matter how much money we make from foreign arms sales, it is just the icing on the cake."
