949 Chapter 949: Progression 5
The transport plane Aslan boarded was not a transport plane independently developed by the Melox Empire, but a large military transport plane purchased from the Holy Bretta Empire, the Yun-20. five years.
As a large multi-purpose transport aircraft, the aircraft can perform long-distance air transport tasks of various materials and personnel under complex weather conditions. Compared with the Gwen II transport aircraft currently in service in the Merox Empire.
The engine of 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 Yun-20 is
320 tons, the maximum load capacity is more than 100 tons.
The turbofan engine with higher power is a high-end technical equipment that the Merox Empire cannot produce today, and its speed is several times that of the original Imperial transport aircraft. After all, the Merox Empire uses piston engines, mainly for propeller aircraft.
Looking at the development of aero-engines, the piston engine first appeared, and the piston engine made the human dream of flying for the first time truly realized.
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, which leads to a rapid increase in engine capacity, 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, 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 first successful 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 human beings.
Aviation engine technology continues to develop, and 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 propfan engine etc.
The driving principle of a turboprop engine is roughly the same as that of a traditional propeller aircraft that uses a piston engine as a power source. The thrust or pull generated when the propeller rotates is used as the driving force for the aircraft to move forward.
Compared with the vertical engine + propeller, the turboprop engine has many advantages. First of all, it has more power and a higher power-to-weight ratio. The maximum power can exceed 10,000HP, and the power-to-weight ratio is above 4, while the maximum power-to-weight ratio of a piston engine is only 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. Also, due to the thin gas generator at its core, turboprops have a much higher altitude and speed range than piston engines.
In terms of fuel consumption, the two are about the same, but the kerosene used in the turboprop engine is cheaper than the gasoline used in the piston engine. At present, the most representative turboprop engines are single-shaft and free-turbine.
Gwenaville's main challenge now is the turboprop engine, which is the new technology most likely to be developed by the Melox 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 grassland, where it rose to an altitude of 10,000 meters, then turned around and flew towards the Moratti Defense Line Command.
Before reaching the altitude of 10,000 meters, it is easy to be noticed by mentor-level powerhouses.
Yun-20 was refitted by Gwennaville, and the main fuel was also changed to the existing common fuel coal crystal in the mainland. That thing is more stable than fuel and has higher combustion efficiency. The most important thing is that it can be converted into magic power.
The appearance is also equipped with phantom magic, coupled with sound insulation and isolation magic, after take-off, as long as you don't use mental power to check, you can't find its existence at all.
Because the distance was too short, it took less than half an hour from takeoff to the destination. Natal was very surprised to see the vast white clouds outside the window.
"How can you be sure we are where we are?"
Aslan smiled mysteriously and said, "This is a secret!"
"The aviation bomb has been dropped, and it will start to land in two minutes."
The captain's announcement sounded in the cabin.
"action!"
Aslan gave an order, more than 30 people headed towards the rear of the cabin. They were located in the middle of the cabin and entered the rear cabin. Hold your heels and go out against the wind.
The aerial bombs dropped at an altitude of 10,000 meters, and they were dropped by transport planes, so the accuracy is naturally hard to say. The real purpose is to bomb them randomly and create chaos for the Free Magic Alliance.
The aerial bombs were dropped two minutes before Aslan’s airborne landing, which happened to be within the distance between Moratti’s line of defense and the headquarters. Be nervous for a while.
The dragon-slaying knife team jumped out of the cabin in order and began to fall towards the predetermined position without using magic, because any magic fluctuations would be detected by the magic radar.
The magic element radar is a radar independently developed by the city of magic. The magic wave radar has the same function as the radar wave. The magic element radar monitors magic elements. As long as magic is used, even the lowest level of magic, as long as it is within the detection range of the magic radar , will still be found.
This is also the reason why Aslan chose the dragon slaying knife team. They are all dragon slayers. When they landed at high altitude, they can open their dragon wings and glide.
The Duke of Medea had Aslan, and Natal and the others were covered by members of the Dragon Slaying Squad.
Aslan moved behind Duke Medea, wanting to hold Duke Medea's waist in his arms, and Duke Medea turned around to face Aslan, and put his arms around her waist At the same time, she hugged Aslan's neck tightly.
The bombing attracted the attention of many powerful people in the headquarters, allowing Aslan and the others to land in the target area without any risk.
"This is Squad 1. The airborne is over. There is no enemy response at present. Please answer each squad. Each squad..."
As soon as Aslan landed, after confirming that there were no enemies around, he directly used the communicator. The magic band used by the communicator was similar to that of the magic capital, and it was not within the detection range of the magic element radar.
"Squad 2 airborne is over, and Squad 3 has been contacted, and there are no enemy troops around to respond."
"Squad 3 here, also no enemy reaction."
"Very well, each squad began to perform infiltration and sabotage operations. Squad 2 went to Point B, Squad 3 went to Point C, and we went to Point A. Considering the speed of the enemy's strong return, the time limit is five minutes. After the attack is over, evacuate at full speed. .”
Aslan calmly gave the order.
"Yes!" Peyton, the monitor of Class 2, replied.
"Understood!" Class 3 monitor Gravin replied.
"All staff assault!"
