Take Off My Aviation Era

After hearing Lin Guanghua's words, Zhuang Jianye frowned subconsciously.

Ascendas Group now indeed has turboshaft engines, based on the hx-4-1 core engine, the d-30-z series turboshaft engines derived from the improvement of the d-30 series gas turbine power plant.

According to different processes, the d-30-z series turboshaft engines are roughly divided into three versions, with power ranging from 296 kW to 554 kW.

At that time, Ascendas Aviation didn’t have any established model plans for turboshaft engines. Just seeing the turboprop engines mature step by step, I wondered if we could use the mature reduction gearbox, transmission mechanism, bearing combination and combination of turboprop engines. The control system, coupled with the derivation of the hx-4-1 core machine, is ready to make some in-depth improvements and turn it into a turboshaft engine for helicopters.

Due to the experimental nature, the benchmark model uses the mature d-30 series gas turbine power unit of Ascendas Aerodynamics, hoping to accumulate experience for the future d-40 series or d-50 series conversion of turboshaft power.

Because of this, the d-30-z series turboshaft engines have entered the substantive research stage since a year ago. Originally, there was no hurry to take off aerodynamics. Anyway, it is the experimental nature, and it is solved for the mice of the subsequent models. Whether there is any problem, the good or bad must be put later to digest slowly.

So when it comes out, Ascendas Group is very Buddhist.

However, after the notified ministries and commissions learned of the specific parameters of the d-30-z series turboshaft engines developed by Ascendas Aerodynamics, they immediately dispatched several expert groups to Ascendas Aerodynamics to conduct research on the d-30-z series turboshaft engines. Extremely meticulous research and demonstration.

Finally, it is concluded that the d-30-z series turboshaft engines conform to the supporting power plan of the light multi-purpose military and civilian helicopters just proposed in China, and are supported in principle.

The light multi-purpose military/civilian helicopter has a long name, but it is actually the later Zhi-11 helicopter.

In the early stage of the Zhi 9 alone, the middle of the Zhi 10 shining, and the Zhi 20 opened the prelude to the new era, the presence of the Zhi-11 helicopter is actually very low.

But low does not mean that it is not important. In fact, the starting point of Zhi-11 is still very high, because its benchmark models are the French "Squirrel" series helicopters and the American Bell-206 series helicopters.

These two helicopters are world-renowned light helicopters, especially the Bell-206 series helicopters in the United States. Many sub-models are derived according to different needs, the most important of which are three. One is the passenger sightseeing model, and the other is the helicopter instructor. Machine, and finally the military model.

The first is the most common civilian model, which carries 7 people including the driver or hoisting equipment of the same weight for short-distance passenger transportation, ground-to-air surveying and mapping, aerial photography and other purposes.

The second is the daily training of pure helicopter pilots and the adaptive training of go-around pilots. After all, the maintenance and use costs of light helicopters are relatively cheap, and they are an ideal platform for helicopter training.

The last and most important category is the light armed reconnaissance helicopter. The most typical is the Bell-206 series helicopter improved model oh-58a "Kiowa" light armed reconnaissance helicopter.

As the main component of the rapid assault force of the U.S. Army Air Force, the helicopter forms a high-low collocation with the ah-64 Apache armed helicopter, combining light and heavy, a low-altitude fire strike system, specifically designed to fight against the European wilderness that may break through the iron curtain. The torrent of Soviet steel.

As for the effect, the Gulf War a few years later is the best proof.

Of course, it is not expected in the country a few years later, but in recent years, several French "Squirrel" series helicopters and American Bell-206 series helicopters have been introduced through civil aviation, and they feel very good after use.

In particular, the army, whether it is the Army Aviation Corps, which has just been formed by the Army, or the helicopter forces that the Air Force itself possesses, or the carrier-based helicopter forces that the Navy has begun to expand, require a large number of helicopter pilots, and the training of professional helicopter pilots must be professional. Helicopter trainer aircraft.

However, the lack of domestic understanding of this aspect caused the helicopter trainer to be blank until the end of the 1980s. Compared with the perfect fixed-wing trainer and training system, the gap is not a little bit.

What's more, light helicopters also play a very important role in frontline reconnaissance, armed assault, and fixed-point anti-tank. Especially after the introduction of the French "Small Antelope" light gunship, the Army Air Force has a high evaluation of this flexible and lightweight helicopter platform. It is hoped that similar equipment will be available in the country as an important force for aviation reconnaissance and ground-to-air anti-tank. After all, China is also threatened by the Soviet steel torrent on the northern border.

As a result, under the promotion of many parties, the light multi-purpose military/civilian helicopter began theoretical demonstration in 1986, and the basic structure was officially determined in 1988, and it was officially developed.

Like many domestic aircraft, the light multi-purpose military/civilian dual-purpose helicopters also have uncertainties in terms of power. According to the plan of the development project team, the light multi-purpose military/civilian dual-purpose helicopter adopts the imitation of the French Ahye series. The turboshaft 8 of a turboshaft engine.

With the introduction of the domestic turboshaft engine along with the French "Dolphin" helicopter, the overall performance is not bad, and it fully meets the needs of light multi-purpose military and civilian helicopters.

However, the localization was stumbled. The light multi-purpose military/civilian dual-purpose helicopter development project team went to the turboshaft 8 production plant several times. Although the manufacturer was convinced, the leaders of the development project team were still a little worried. No way, they are all veterans in the aviation industry. Who has not experienced the embarrassing scene of airplanes and other engines?

In order for the light multi-purpose military and civilian helicopters to not fall into the pitfalls of the previous power system, and to turn a skit into a boring and lengthy soap series, another power replacement is necessary.

And this is also the common practice of the world’s major aviation production giants. Take Airbus as an example. Their aircraft usually have three sets of power schemes~www.readwn.com~ They are Rolls-Royce, Pratt & Whitney, and General Motors. It’s called a backup plan. The bad thing is that you can’t hang it on a crooked neck tree. Otherwise, my aircraft is designed to seize the market, but it turns out that the power hasn’t come out and Airbus has to cry to death.

In the past, there were no such conditions in China. After all, there were only a few domestic aero-engine manufacturers, and because of historical reasons and the planning system, the production of turbojet can only produce turbojet, and the production of turboshaft must be honestly produced. The vortex shafts do not belong to each other, and they are very clear, and there is a posture of old and dead.

Faced with this situation, the research and development project teams of each aircraft can only hand over the power part to a sorting factory for development in accordance with the instructions of the ministries and commissions. As for when it can be completed and installed on the aircraft to complete the finalization, only God knows.

But now it’s different. There is a freak of Ascendas Group. As long as it is related to aerospace, almost all are involved, especially in aero engines. It completely jumps out of the ministry’s plan. Several series of gas turbine power plants have been formed in a few years.

Looking at the light multi-purpose military\civilian dual-purpose helicopter development project team, what are you waiting for? I decided to designate the d-30-z series turboshaft engine as the light multi-purpose military\civilian dual-purpose helicopter. Standby power shall be sub-system approved.
