Qin Guan finally began to lift the transport plane.
If you want to have strategic air transport capacity, you must have large transport aircraft. Now, look at the world, the Schott brothers
The company's sc-5 "Belfast" four engine large turboprop transport aircraft is the most suitable choice.
As a large transport aircraft, its initial model has a takeoff weight of nearly 100 tons and a maximum transport capacity of 36 tons.
It can transport army heavy equipment, such as large caliber artillery, missile systems and armed personnel, and can carry about 200 fully armed personnel.
It also has great potential. For example, its last improved model is sc-5 / 41. This model goes further and aims at Eagle's c-141 transport aircraft. It adopts a newly designed wing and rb178 to form a combination. Like c-141, it adopts a T-shaped vertical tail, with a maximum takeoff weight of 190 tons and a maximum load of 54 tons for military models.
This means that this transport aircraft can transport main battle tanks!
Unfortunately, in history, the dream of building niuguoren's own large jet transport plane was finally dashed. Although the Schott company in the political competition was ambitious, it still bid farewell to this atmospheric transportation overlord with disappointment. The Royal Air Force of NiuGuo finally symbolically purchased about 10 and invested most of its funds in the purchase of the eagle's Hercules transport aircraft.
Now, the state of Han has begun to develop Yunshi. Under the promotion of Qin Guan, Yunshi will not end up with nothing like before. This latest airliner of the state of Han must be developed.
In this way, we already have yun10. Do we need other transport planes?
The answer is yes.
Although Yunshi begins with the word "Yun", it is an airliner. There are many differences between this airliner and transport aircraft, which is not to say that it can be simply replaced.
It is mainly due to different technical requirements due to different use purposes
For example, the transport aircraft is mainly for military transportation, so it should meet the needs of the army. For example, it should have the take-off and landing capacity of the field airport, good low altitude and low speed capacity to facilitate airdrop operation, good fast loading and unloading capacity, including the cargo movement system in the aircraft, capable of transporting long objects and vehicles, and the strength of the cargo cabin floor can carry overweight cargo Special facilities for airdrop.
These features are not needed by passenger aircraft. Compared with transport aircraft, passenger aircraft pay more attention to passengers. For example, safety, comfort, fuel saving and reliability can ensure departure rate and low noise.
Because these main requirements are different, transport aircraft and passenger aircraft are very different.
In terms of layout, airliners often use lower single wing, low flat tail, conventional front three-point landing gear and lower wing double release Bureau, and transport aircraft use upper single wing, high flat tail, belly multi wheel landing gear and lower wing four release Bureau.
The upper single wing means that the wing is at the top of the fuselage, which can ensure the ground clearance of the engine under the wing. After all, for transport aircraft, it is often necessary to take off and land on non paved field airports, so as to avoid damaging the engine by the sand and gravel raised on the ground during take-off and landing on a rough runway.
At the same time, multi wheel landing gear is necessary to reduce the pressure on the runway of the field airport. It is also conducive to reducing the floor height of the engine room and the angle of the tailgate loading and unloading springboard, so as to facilitate rapid loading and unloading and vehicle entry and exit; High flat tail reduces the impact of flat tail downwash air flow on tail airdrop; The four engines ensure strong power, which is conducive to shortening the take-off distance, or quickly accelerate the climb and leave after the air drop under the enemy's fire, and increase the ability to resist war damage.
For the passenger plane, if it is arranged in this way, it is not only difficult to overhaul the engine, but also the noise of the engine can be clearly transmitted to the cabin. It is definitely not a good enjoyment for passengers, it is simply a kind of torture.
At the same time, the body is also different.
In terms of cabin section, the passenger plane is used to carry passengers. The height between the floor and ceiling needs to ensure that passengers can stand comfortably, but it is not necessary to be higher. The most important thing is to ensure that standard air containers can be accommodated under the floor for proper loading. On the other hand, the bulkhead on the side of the aircraft should be almost vertical, otherwise the passengers near the window will either have their head space squeezed or their leg space squeezed, which will be uncomfortable.
However, the transport aircraft needs to maximize the cabin volume in order to load long but not overweight objects, such as missile carriers and special vehicles. Therefore, the floor is as low as possible, and the ceiling is completely empty to maintain the maximum complete space. In addition to additional reinforcement, the floor needs to have a large number of mooring points for fixing equipment; There shall also be rollers, guide rails and traction cranes in the cabin to help the goods move in the cabin.
Moreover, for the convenience of transport aircraft, in addition to the opening at the tail, some aircraft even have hatches at the nose, which can enter and exit from the front and rear.
These requirements are different. It is difficult to change an airliner into a transport aircraft. It is uncomfortable to change a transport aircraft into an airliner.
For another example, as for the early warning aircraft, Eagle country is refitted with an airliner, so the members inside are very comfortable, and there is even a lounge. Xiong country is transformed with a transport aircraft, which is quite uncomfortable, noisy and tight space, which is not conducive to maintaining its combat capability.
At present, there is also a gap in transport aircraft in Han Dynasty.
It's good for Yunshi's team to get Yunshi out. Let alone compete in the international market, the domestic airliner market is huge.
Transport aircraft, mainly for military use, need to be imported.
What is there in China now?
The most is Yun eight. The transport plane transformed from the an-12 transport plane of Xiong Guo is only 50 tons, which is even a medium-range transport plane. In terms of heavy transport aircraft, the Han country has always been blank, which can be regarded as a solution to the urgent need until the emergence of the Yun 20 in later generations.
Now, hearing Qin Guan talking about this transport plane, Royce was surprised: "do you want sc-5 transport plane?"
Although it belongs to the Schott brothers, their NiuGuo aerospace company can pass on the message. If Qin Guan takes this Agreement as a necessary additional agreement for the sky flash missile, it will be troublesome.
Qin Guan nodded: "yes, we need this transport aircraft. As for the purpose, you don't ask. In short, we just want to, and we also need to introduce technology to realize our own production in our country."
Can the other party give it? The first use Qin Guan thought of was to exchange it for good things in the Sabbath. Moreover, if his own production and spare parts sources were available, he could persuade the Sabbath to give their good things to his own side.
Moreover, after the Han state produced its own products, it was also of great benefit to the Han state. Now, Qin Guan has made up his mind and has to do it when it is time to do so.
And those supporters, such as submarines, get advanced technology from each other bit by bit, so as to realize the great leap forward development of the motherland!
