Porcelain Town took the risk of using the MZ-2200 engine that has not yet completed the final finalization for flight testing, of course, Chief Yin knows this situation, and even the test flight subjects of the Z-18 over there are all formulated by him and confirmed that it is relatively safe, which ensures that the test flight can be carried out, and now at this time, naturally everything is no longer to worry. Pen "Fun" Pavilion www.biquge.info

"On the engine side, at most the end of this year to be able to complete all the finalization tests, we are waiting for the national acceptance of the finalization, now the technical indicators tested out of the data have all been clear, in fact, we should now call it MZ-2300 more appropriate, because the test data we obtained directly shows that the actual data of this engine is to reach 2360 horsepower, as for the emergency output power not to mention, so we after a comprehensive trade-off, The conventional maximum output in the MZ-2200 engine control system was set at the 2300 hp position. ”

After all, it is the core engine used in the MS-4 turbofan engine, and the core engine technology is already quite excellent, and various new technologies are also used in the development of the turboshaft engine, which unconsciously increases the maximum output power of the engine.

As for the actual power of the MZ-2200 engine is larger than the rated power in the previous plan, and whether it will bring any intuitive benefits to the Z-18 at that time, this will not be too obvious, probably when flying on the plateau route, it can show the difference between the two more prominently.

After understanding these truths, Yang Hui was relieved: "Okay, then now you have to speed up the development progress of the MZ-2200 engine, and you can't relax the follow-up technical pre-research work required to improve the performance of this engine, whether it is to start from improving the life of the engine, or to work the power, anyway, all of these have to start pre-research, I feel that after the successful development of the Z-18, there may be other heavy helicopter projects on the ground, you must be prepared." ”

The successful development of the straight 18 will certainly be accompanied by a stimulus to other helicopter model project development, heavy armed helicopters, heavy helicopters and other projects will also have, at that time the helicopter bidding war between AVIC Southwest and AVIC Northeast is really hard to say who will die, after all, the Northeast side has more experience accumulation in armed helicopters, but the two have their own focus on the technology of the helicopter development side.

So for the MZ-2200 engine, Chief Yin has a lot of confidence, maybe in the future, it is possible for this family of engines to dominate two-thirds of the domestic turbo and turboshaft engine market, and then all that is needed is to work this engine.

"Mr. Yang reminded that it is not unreasonable, after we develop an engine, we want to continue to dig deeper into its capabilities, MZ-2200 is a good engine with enough potential, we will definitely not easily choose to start anew, otherwise the plan to provide power systems for the new boat will not be able to fall on our heads, I think now if Dong'an knows the news, I am afraid that I will be in a hurry to jump ah!"

Dongan Power, as a factory of AVIC Northeast's aviation turbine company, produces engines that are transferred from Zhuzhou in the 80s to the turbo 5 series engine, which was specially designed for the power system of the domestic Yunqi series, and now the MZ-2200 engine can be installed on the new boat, which also means that the military Yunqi turbo 5 engine can be pushed down, so it is strange that Dongan does not jump and scold his mother.

But fortunately, the news at this time has not yet passed, as long as this side can take the first step to sign the contract with the Iranian side, even if Dongan knows it, it can only be helpless, who you call AVIC Southwest is now awesome, as long as the technology is good, it is really not afraid to go all over the universe.

As for the data after the MZ-2200 was changed to a turboshaft engine, in fact, the 608 Institute on Zhu Zhou's side had relevant research a long time ago, at least from the technical point of view, the difference between the turboshaft and the turbo is not big, the early turboshaft and the turbo are even directly mixed, and the relationship between the two engines is similar to the grievances between the leaky turbojet and the small bypass ratio turbofan.

Chief Engineer Yin, who has long been well versed in this reason, has not had the slightest worry, and said with a smile: "The matter of mz-2200 to change the turbo pulp engine, we have actually studied it before, and now if the company can carry out the project, we will be able to build an engineering verification machine before the end of the year, and it will be delivered in the second half of next year at most, there is really not much difference between the vortex shaft and the turbo pulp, we will definitely be able to keep up with the prototype manufacturing speed of the aircraft over there, which I can still guarantee." ”

In a sense, in fact, compared with the turboshaft engine, the former is simpler in the reducer, and the number of stages of the reducer is less, which means that the power lost in the middle will be much smaller, and the same MZ-2200 will be changed to a turbo engine after the engine, there will be some increase in output, which is very normal.

And even if the power does not increase, as long as the turbo engine improved by the MZ-2200 can ensure that the power will not decrease, this is enough to compete with the Pratt & Whitney PW-127 series turbo engine produced by Canada used in the Xinzhou series and the previous Ukrainian An-140, and the output of 2300 horsepower can definitely meet the requirements of the new boat.

But it's one thing to say that the power can be satisfied, in fact, you definitely need to hear the data about this engine in person before you can rest assured: "How much power can be reached, or the overall performance of the engine can catch up with the PW-127 series used by Xinzhou before, this is what I want to know."

PW-127 series engine from the Canadian Pratt & Whitney company, all aspects of the performance is extremely good, Yang Hui this time directly to Canada Pratt & Whitney for comparison, the pressure and expectations are naturally not small, and Yin as the chief engineer of the MZ-2200, for this engine in all aspects of the door is clear, after the silent comparison in his heart there is a result.....
