Chapter 1222 Improvement of Helicopter

Fleet's expression changed even more. In the entire German military development, the Führer Cyric played an irreplaceable role. The direction he pointed out turned out to be completely correct.

As a result, many military experts are praising the fact that the President of Cyric is simply omnipotent and plays an irreplaceable role in various fields. The problems they often encounter cannot be solved. As a result, the President of Cyric gave a sudden It was pointed out that even the most professional people admired Führer Cyric very much.

And now, the President of Cyric actually said that this helicopter has fatal flaws, so it must be there. So, is the helicopter that he has spent more than ten years developing, is it going to waste?

This made Fleet's heart tremble. He didn't even have confidence in the next performance of his helicopter, and said carefully to Cyric: "Führer Cyric, what is the fatal flaw of this plane? ?"

"The reversal torque cannot be effectively overcome by this helicopter, which will cause the aircraft to be unable to maintain its excellent balance performance during flight. As long as the weather conditions outside exceed, the balance of the aircraft will be destroyed. Risk of crash," Cyric said.

This sentence immediately surprised Fleet. Sure enough, just like the legends in the outside world, the President of Cyric can always point out the problem of his own plane at once!

In the process of helicopter development, it is this reversal torque that has always been shrouded in the minds of various designers.

When the propeller is rotating, it can be imagined that a wing is rotating, and the rest is the fuselage. Then, why is the wing not moving and the fuselage rotating?

The effect of force is mutual. When the propeller is rotating, the fuselage actually wants to rotate along with it. (This point is best explained by taking an airplane model. If you hold the propeller of the model airplane and keep it from turning, then, driven by the engine, the airplane will rotate in the opposite direction.)

In fixed-wing aircraft, this is an unavoidable problem, but the fixed-wing aircraft has a larger wing behind it, and at the same time, the fuselage cancels this moment. Even so, when the aircraft takes off and lands, if it does not If you pay attention, you may still be led into the ditch by this problem, and the fuselage will inexplicably flip, resulting in a big top.

For fixed-wing aircraft, this problem is not particularly serious, but in helicopters, this problem is quite dire.

In order to lift the helicopter directly, the lift generated by the top propeller must be greater than the gravity, so the propeller of the propeller plane is very large, and the torque generated is also quite strong.

How to overcome this moment? Just look at the current Fleet helicopter. Its rear fuselage has four tall vertical tails, which is much larger than the vertical tail area of ​​ordinary aircraft. Fleet uses this method to increase the stability of the course. Sexual, but this is only a temporary solution.

Fleet's approach doesn't solve the problem.

At this time, the helicopter was still flying, but Fleet felt the sweat on his forehead swishing outwards. Head of State Cyric mentioned a serious defect. Will this helicopter be discontinued because of this defect?

"Then, Führer Cyric, how do we overcome this defect?" Fleet asked cautiously: "We have indeed been plagued by this problem for a long time."

His eyes were on Cyric. If Cyric had no answer, the helicopter would be sentenced to death, and his ideals would be shattered.

"The solution is also very simple, just provide a reverse torque." Cyric said.

How to solve? It will be known from later generations that all single-rotor helicopters have a tail at the tail, and there is also a rotating propeller there.

What is that propeller for? Of course, the airflow is blown to the side, which is just used to offset the reverse torque. At the same time, by controlling the output torque of the tail propeller, the helicopter can easily turn while hovering.

Cyric was only responsible for providing ideas, and as soon as his idea came out, it immediately made Fleet happy. Yes, this is the best solution to the helicopter problem.

Moreover, in this case, the tail does not need to be so bloated at all, just a small tail and a suitable propeller will do!

In later generations, more than 90% of helicopters have this layout, and only a small number of helicopters are dual-rotor helicopters, which can use two coaxially installed rotors that rotate in opposite directions, or can be installed in front of the fuselage. A rotor with opposite directions is installed at the front and the rear, so that the generated torques cancel each other out, so there is no need to set up an anti-torque tail rotor.

But the rotor has always been the mainstream, and the plan proposed by Cyric made the designers feel at ease. A new cross-generation aircraft is about to hit the stage of history!

Although German helicopters have been developed in World War II, they did not have too many equipment troops and did not play a big role. After they continued to improve after the war, they began to show their superiority on the battlefield.

And now, under the impetus of Cyric, the helicopter has also begun to develop rapidly.

"The Navy's carrier-based helicopters are only a small part of the needs of helicopters." Cyric continued to express his views: "In our army and air force, we need a large number of helicopters."

"For example, our mountain division is equipped with a certain amount of helicopters, which can help us overcome various environments in the mountains. It does not require a flat runway, but only a small open space to land." Cyric said: "And such Helicopters, preferably large ones, can even hoist our various vehicles."

"We can also try to put weapons such as rockets on helicopters and transform them into armed helicopters for ground attacks. These can also be equipped with ground troops, so that ground troops do not need to call for air support, and they have a lot of power. Strong fire support capability."

The development of helicopters will take a long time, but under the stimulation of the war, the process will be greatly shortened. For example, now, Germany has begun to develop various precision-guided weapons, and wire-controlled anti-tank missiles are also in the sequence. , so, mounting rockets to helicopters, or even anti-tank missiles at a later stage, can be completed within a few years.

Fleet's eyes burst into flames. Under the outline of Führer Cyric, helicopters will become the main equipment in the future. He will also become Germany's aviation technology like Messerschmitt and Dr. Cook. Elder!
