In the pergola.
Everyone stood up in shock. He stared dumbfounded at the violent Swordfish like a wild beast about to be released from the cage.
Xun Shifei was surprised: "This... is such a powerful driving force."
"Yes. This power is a bit too overwhelming. Dust is swirling on the ground."
"Look, it's like it's about to break the rope. It's such a powerful and surging force."
"Its speed should be much faster than an airship, right?"
"That's for sure. The airship uses a four-stroke engine. And this, I heard, is the latest technology from the Kyushu Academy of Sciences. It's called a star-shaped repeating engine."
"Is this engine that powerful?"
"The sound is much more powerful than that of a four-stroke engine. This sound alone gives people a shocking feeling."|
"Can it even take off straight up and down?"
“…”
The surging power of the radial engine shocked everyone present.
They also roughly understood the principles of these aircraft, but they did not expect that the power behind them would be so powerful. The power source is not on the ground, it just pushes the air to generate wind. This reaction force is so powerful.
If this kind of engine was installed in a car, wouldn't it be even more outrageous
In fact, they were wrong about this.
Compared with the four-stroke radial engine, there is actually not much advantage in power. The biggest advantage is just the huge torque.
Extremely suitable for marine propellers and aerospace propellers. Not suitable for cars on land.
Furthermore, compared with four-stroke engines, radial engines consume more fuel. And it's louder.
Running on land, it's a noise maker. If such a car were driven in Laoshan County, the whole city would be scolded.
It is also currently only suitable for aerospace use. Theoretically, it can be regarded as the first generation aeroengine.
certainly. In fact, if conditions permit, four-stroke engines and even two-stroke engines can be used in aerospace. All can be used as aircraft engines.
However, based on the current level of industrial technology. Four-stroke and two-stroke engines stall too easily.
There is such a common problem in today's cars. Sometimes the car stalls for various reasons as soon as it is driven and needs to be restarted. The good thing is that it is an electric ignition now, not the crank type compression ignition, so everyone can accept it.
But if it is used in aerospace, this instability will have a high probability of causing an air crash. If the engine stalls in the air, it is a narrow escape for the aircraft and the pilot.
Even though it consumes more fuel, there is no obvious advantage in power. Still want to use a more stable engine. After so many tests, the motor vehicle institute has not even experienced a radial engine stalling.
Liu Jinghong put on his flight helmet, leather armor, and windshield.
Really handsome.
That heroic appearance made everyone yearn for the blue sky and become a pilot.
Liu Jinghong wanted to test the flight himself. But everyone spoke up and stopped him from doing this.
Even Xun Shifei said: "That won't work. You are a national treasure of New Kyushu. What if you have an accident? The Eastern Military Region has specialized pilots and professional test pilots. Why do you need to take risks yourself? Don't think you are manufacturing It’s for airplanes, but you really don’t have as much flying experience as others.”
What Xun Shifei said is clear and logical. In addition, many people were trying to dissuade him, so Liu Jinghong could only retreat in embarrassment. I thought to myself that I was wearing a pilot's outfit today for nothing, it was so embarrassing.
"Report."
"The power system is stable and safe, and the power system can be tested for flight."
"The take-off and landing system is stable and safe, and the take-off and landing system can be tested for flight."
"Report, the control system is stable and safe, and the control system can be tested."
"The instrument panel is all stable, safe and ready for test flight."
"Report, the take-off runway is stable and safe, and can be used for test flights."
“…”
The personnel of the Aviation Academy went through professional and rigorous testing and issued a final report.
At this time, three young men strode out from a military team around the pergola. The three young men are all about 1.6 meters tall. Each of them is wearing a flight helmet, windproof goggles, ventilator, windproof leather armor and leather gloves. Each of them carries a parachute bag behind his back.
Walking to the pergola, the three of them saluted together. The captain stepped forward and shouted loudly:
"The New Kyushu Army, the Eastern Military Region Flying Army Formation, and the 001 Flying Regiment are here to report. Three people were supposed to be present, but actually three were present. The leader is Fang Aerospace. Please give instructions."
Everyone in the pergola stood up and saluted in return.
Liu Jinghong took a step forward: "I am Liu Jinghong, director of the Aeronautical Research Institute of the Kyushu Academy of Sciences. I am developing a new aircraft and need one person to complete the test flight. Captain Fang Aerospace, please select one person from your ministry."
Fang Hongtian took a step forward: "I'm coming!"
Liu Jinghong nodded, called him into the pergola, and began to explain the principles of the Swordfish to him. and various operating systems.
Fang Hangtian listened carefully and knew what was going on.
This can be said to be one of the oldest pilots among the first batch of pilots in the world. During the military parade, he drove the airship in a circle.
From airships, to hot air balloons, to unpowered paragliders and powered paragliders. He is proficient in any aircraft that exists in New Kyushu.
Regarding aerospace, his hard work has not been neglected at all. Like many people, he loves the blue sky.
This time a new type of aircraft appears, with completely different operating concepts and completely different functions. He didn't have any fear or anxiety, only ecstasy and excitement.
You will be the first person in the world to try out a new type of aircraft, how can you not like it
Liu Jinghong said seriously: "The operating system and the airship are the same. The control stick on the left hand, pushed up and down, controls the upward direction. The control stick on the right hand, pushed left and right, is responsible for turning left and right. The one under the foot is the accelerator, which I don't need. You know it. This dashboard is the code rate. Only when the code rate reaches a speed of 80 kilometers per hour, the aircraft can take off. If the speed does not reach 80, do not take off rashly."
Fang Hongtian listened carefully, then climbed into the plane and turned off the engine, and conducted practical operation experiments.
The control system is not unfamiliar, it is similar to that of an airship. The joystick controls the direction, and the foot pedal controls the accelerator.
The difference is that the airship goes straight up and down, but this one requires a run-up to take off. When landing, you also have to glide and land.
The control system is similar to that of an airship. The takeoff mode is the same as for a powered paraglider.
Fang Hongtian did not find it unfamiliar or difficult. On the contrary, he was very familiar with these operations. Even if he had never tried it, he was familiar with it. It's a feeling. A kind of confidence that has a total flight time of more than a thousand hours and conquered the blue sky for too long.
