Flett's face changed. In the whole German military development, head of state Chirac played an irreplaceable role. The direction he pointed out was finally proved to be completely correct.
As a result, many military industry experts were praising head of state Chirac. He was omnipotent and played an irreplaceable role in all fields. Many times, the problems they encountered could not be solved. As a result, head of state Chirac pointed out at once. Even the most professional people admired head of state Chirac very much.
Now, the head of state of Chirac actually said that there were fatal defects in this helicopter, which must be there. So, is the helicopter he spent more than ten years to develop going to fail?
This made Flett's careful liver tremble. He didn't even have confidence in the next performance of his helicopter. He carefully said to Shrek, "what's the fatal defect of this plane, head of Shrek?"
"The reverse torque cannot be effectively overcome by this helicopter, which will lead to the aircraft's inability to maintain excellent balance performance in flight. As long as the external meteorological conditions exceed, the aircraft's balance will be damaged and there will be a risk of crash at any time." Said Shrek.
This sentence immediately surprised Flett. Sure enough, as the legend goes, head of state Chirac can always point out the problem of his plane at once!
In the process of helicopter development, this reverse torque has always been shrouded in the hearts 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 not the wing is stationary and the fuselage is rotating?
The forces act on each other. When the propeller rotates, the fuselage also wants to rotate with it（ This is best illustrated by the model aircraft. If you grasp the propeller of the model aircraft and don't let it rotate, the aircraft will rotate in the opposite direction driven by the engine.)
In fixed wing aircraft, this is an inevitable problem, but there are larger wings behind the fixed wing aircraft, and this torque is offset in the fuselage. Even so, when the aircraft takes off and lands, if you don't pay attention, it may be taken into the ditch by this problem, and the fuselage will turn over inexplicably, resulting in a big top.
For fixed wing aircraft, this problem is not particularly serious, but on helicopters, this problem is quite terrible.
In order to directly lift the helicopter, the lift generated by the propeller at the top must be greater than the gravity. In this way, the propeller of the propeller aircraft is very large and the torque generated is also very strong.
How to overcome this torque? Look at Flett's helicopter now. Its rear fuselage has four tall vertical tails, which is much larger than the vertical tail area of ordinary aircraft. Flett increases the stability of heading in this way, but this is only a solution to the symptoms rather than the root cause.
Flett's solution can't solve the problem.
At this time, the helicopter was still flying, but Flett felt the sweat on his forehead whizzing outward. Head of state Chirac said that there was a serious defect. Will this helicopter stop production because of this defect?
"Then, head of state Chirac, how can we overcome this defect?" "We've really been troubled by this problem for a long time," Flett asked cautiously
His eyes looked at Shrek. If Shrek said there was no solution, the helicopter would be sentenced to death and his ideal would be disillusioned.
"The solution is also very simple. Just provide a reverse torque." Said Shrek.
How to solve it? It will be known to future generations that all single rotor helicopters have a tail wing at the tail, where there is also a propeller rotating.
What's that propeller for? Of course, it is blowing air 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 turn easily in hover.
Hilrick was only responsible for providing ideas, and as soon as he spoke out, he immediately delighted Flett. Yes, this is the best solution to the problem of helicopters.
Moreover, in this way, the tail doesn't have to be so bloated at all. It only needs a small tail wing and a suitable propeller!
In later generations, more than 90% of helicopters have this layout, and only a few are twin rotor helicopters. Two rotors rotating in opposite directions can be installed coaxially, or a rotor rotating in opposite directions can be installed at the front and rear of the fuselage, so that the torque generated can offset each other, so it is not necessary to set a torque resistant tail rotor.
However, the design of the rotor is always the mainstream, and the scheme proposed by Chirac makes designers enlightened. A new cross era aircraft is about to embark on the stage of history!
Although German helicopters had been developed in World War II, they did not have much equipment and played a great role. After the war, they began to show their superiority on the battlefield.
Now, driven by Chirac, helicopters have also begun to develop rapidly.
"The Navy's shipborne helicopter is only a small part of the demand for helicopters." Shrek continued to express his view: "in our army and air force, we need a large number of helicopters."
"For example, our mountain division is equipped with a certain number of helicopters, which can help us overcome various mountain environments. It does not need a flat runway, but can land as long as there is a small open space." "Such a helicopter, preferably a large one, can even lift all kinds of our vehicles," hilrick said
"We can also try to carry weapons such as rockets into helicopters and transform them into armed helicopters to carry out ground attacks. These can also be equipped into ground forces so that ground forces can have a strong fire support capability without calling air support."
The development of helicopters will take a long time, but stimulated by the war, the process will be greatly shortened. For example, now Germany has begun to develop various precision guided weapons, and wire remote-controlled anti tank missiles are also in the sequence. Therefore, loading rockets on helicopters or even anti tank missiles in the later stage can be completed in a few years.
Flett's eyes burst into flames. Under the outline of head of state Chirac, the helicopter will become the main equipment in the future. He will also become the technical veteran of German aviation like Dr. messeschmidt and Dr. cook!
