The transport plane that Aslan boarded was not a transport plane independently developed by the Melox Empire, but a Yun-20 military large-scale transport plane purchased from the Holy Bletta Empire. five years.

As a large multi-purpose transport aircraft, the aircraft can perform long-distance air transport tasks for various materials and personnel under complex weather conditions. Compared with the Gwen 2 transport aircraft in service with the Merlox Empire.

The engine of the Yun-20 is more excellent, the load capacity is also greatly increased, and the take-off and landing performance of the short runway is excellent. The maximum take-off weight of the Yun-20 is

320 tons, the maximum load is more than 100 tons.

The turbofan engine with higher power is a high-end technical equipment that the Merlox Empire cannot produce today, and its speed is several times that of the original imperial transport aircraft. After all, the Merlox Empire uses piston engines, mainly for propeller aircraft.

Throughout the development of aero-engines, the piston engine first appeared, and the piston engine made human beings realize the dream of flying for the first time.

The power of the engine is roughly proportional to the cube of the flight speed. Therefore, as the speed of the aircraft increases, the flight resistance increases with the speed, resulting in a rapid increase in the amount of the starting block, which cannot meet the weight limit of the aircraft.

On the other hand, when the flight speed is close to 800km/h, the tip speed of the propeller is close to the speed of sound, and the formation of shock waves and vibrations will lead to unstable operation of the propeller and a sharp drop in efficiency.

On September 27, 1939, with the successful first test flight of an aircraft equipped with a gas turbine jet engine in Germany, the aviation gas turbine engine brought a qualitative leap in flight speed to mankind.

With the continuous development of aviation engine technology, aviation gas turbine engines have been divided into many types, and their performance has been greatly improved compared with 70 years ago. The main types of existing aviation gas turbine engines are: turbojet engine, turbofan engine, turboprop engine, turboshaft engine and propeller fan engine.

The driving principle of a turboprop engine is roughly the same as that of a traditional propeller aircraft using a piston engine as a power source.

Compared with the live vertical engine + propeller, the turboprop engine has many advantages. First of all, it has greater power and a large power-to-weight ratio. The maximum power can exceed 10,000HP, and the power-to-weight ratio is more than 4. The piston engine has a maximum of three or four thousand horsepower, and the power-to-weight ratio is about 2.

Secondly, due to the reduction of moving parts, especially the piston without reciprocating motion, the turboprop engine has good stability, low noise, long life and low maintenance costs. Moreover, due to the thin gas generator in the core part, the height and speed range of the turboprop engine are much higher than that of the piston engine.

In terms of fuel consumption, the two are similar, but the kerosene used in turboprop engines is cheaper than gasoline in piston engines. At present, the most representative turboprop engines are single-shaft and free-turbine.

What Gwenneville mainly conquered now is the turboprop engine, which is the new technology most likely to be developed by the Merlox Empire. As for the turbojet engine, it is used for fighter jets, and the turbofan engine belongs to the turboprop engine. updated version.

Yun-20 quickly crossed the runway, flew out of the cliff, and slowly flew towards the Ottoman grasslands, where it rose to an altitude of 10,000 meters, and then turned its direction and flew towards the Moratti Defense Line Command.

Before reaching the height of 10,000 meters, it is easy to be noticed by the mentor-level powerhouse.

The Yun-20 was refitted by Gwenneville, and the main fuel was changed to the existing continental general fuel coal crystal. That thing is more stable than fuel oil, and its combustion efficiency is higher. The most important thing is that it can be converted into magic power.
