We hurriedly followed the sound and rushed to Xiao Fei's side. I only heard Xiao Fei hurriedly say: "Hurry up, hurry up, you guys come here, I accidentally bumped into it just now, I didn't expect that there is a door here, is this helicopter real, can it fly?" We are all full of joy, the heart of the heart to push the door open, hurriedly ran in, the original gold helicopter is actually a genuine can be driven by the plane, not we just thought that the vivid giant model sculpture, but the vivid real machine, we rushed in, rushed to the inside from the inside to carefully lock the hatch, this is finally temporarily safe, we temporarily breathed a sigh of relief, this is to look around the various facilities up, this does not see do not know, a look frightened, this is really the life of a tyrant, inside is also a heavy money carefully built, is really unique, as if coming to the seven-star hotel in Dubai, beautiful, magnificent, splendid, the seats made of gold are just the right to be covered with tiger skin cushions, not to mention the big bed made of gold, the wash basin paved with gold, and all kinds of decorations, we are dazzled, dizzying, breathtaking, spacious, comfortable, it is really the perfect combination of modern and classical, let us get carried away, we are concentrating on looking, there is really everything inside, everything is available, we are busy going to the cockpit to take a look, all kinds of instruments and equipmentWe carefully checked and saw that the mode control panel, the main flight display, the navigation display, the engine indication and crew warning system/electronic central aircraft monitoring, the flight management system and various backup instruments, etc., were all intact, and everyone finally completely relieved.

We suddenly smelled the aroma of coffee in the air, and when we looked for the fragrance, we saw fragrant coffee, as well as various delicious drinks such as cola, just like the feeling of first class in modern society, we quickly sat down comfortably, and quickly tasted delicious coffee and other drinks.

, Hu Jiaojiao happily said: "It's really good, it's finally safe, by the way, this time what kind of helicopter thing is different from the flying thing we sat in Crescent Spring last time, although it looks different from the outside, but it looks exactly the same inside, although it is a little similar, but this one is simply much more luxurious, the last time it was really a big deal, by the way, this is the first helicopter?" Although Xiao Fei's arms were seriously injured, he was bleeding just now, but because we stopped donating blood to him in time, he came up to relax for a while, his complexion was much better, and his face was ruddy, he was about to continue to say in a beam, I interrupted his words in time, expressing my intention to let him rest more, and quickly took out his mobile phone from his pocket, searched it, and said unhurriedly according to the script: "No, the first helicopter was in Germany, and its name is F-61." Hannah Reich, a famous German pilot at the time, served as a test pilot. The helicopter's two sets of rotors are mounted on a cantilever mount and are driven by one engine mounted in the nose. The helicopter was invented by the German Fokker. Hannah Reich sat in the cockpit and started the helicopter, and the observers watched with trepidation as the helicopter slowly left the floor of the hall, then hovered in the air at an altitude of about 5 meters, and rotated 360 degrees. When the helicopter landed back on the ground, there was a round of applause in the hall. A few days later, Hannah Reich flew the helicopter from Berlin to London at a speed of 68 kilometers per hour, flying at an altitude of 3,427 meters, setting a world record for a vertical flying vehicle at the time. Hannah Reich also became the world's first female helicopter pilot. But the helicopter is still at the prototype stage and has not been put into mass production. Then there is Igor Ivanovich Sikorsky - the inventor of the world's first practical helicopter, the world's famous aircraft designer and one of the founders of aviation manufacturing, Sikorsky was born in Kiev, Russia, he was obsessed with aviation since he was a child, especially interested in Leonardo da Vinci's helicopter principle and bamboo dragonflies from China, at the age of 12, Sikorsky Jr. made a model of a helicopter powered by elastic bands, showing a creative talent. The decisive event that really cemented his dedication to aviation was the invention of the world's first manned powered aircraft by the Wright brothers, Wilbur Wright flew to Paris for an airplane show, and Sikorsky was fortunate enough to witness the heroic appearance of his predecessors, and decided to build the flying machine himself. So he began to develop helicopters, but at the level of engines and flight theory at that time, the helicopter was simply not likely to succeed. After many failures, Sikorsky had to stop and turn to the development of fixed-wing aircraft, which was thirty years. Sikorsky designed and built the S-1 through S-6 planes, which could only glide on the ground to 1,500 feet and were fully maneuverable. He later designed the S-11, which later became a famous fighter in World War I. However, due to technical limitations, the power of a single engine was small, and the heavy single engine also brought difficulties to the weak structural design at that time, so it was difficult to make a large aircraft at that time. In view of this, Sikorsky decided to develop a multi-engine aircraft, although some aviation people had previously asserted that a large multi-engine aircraft would not technically work. Sikorsky personally flew into the blue sky with a four-engine large aircraft called the Russian Warrior, flying at an altitude of 122 meters and a speed of 104 kilometers per hour, and this aircraft was also the first aircraft to have an enclosed cockpit and passenger cabin. Hu Jiaojiao nodded as if she didn't understand, and then she asked with great curiosity: "What is the difference between this kind of flying machine and the last time?" Hu Jiaojiao really deserves to be a hundred thousand whys, and she seems to be curious about everything, although she listened carefully for a long time, she didn't understand anything.

I had no choice but to continue to read it very patiently: "Helicopters are widely used because they have the advantages that many other aircraft are difficult or impossible to do, and helicopters are mainly used for sightseeing, fire rescue, maritime first aid, anti-smuggling and anti-narcotics, fire fighting, commercial transportation, medical assistance, communications, spraying pesticides and insecticides to eliminate pests, detecting resources and other sectors of the national economy. The ranks of the world's helicopters are growing. There are also helicopter gunships - helicopters that are armed and carry out combat missions. Also known as attack helicopter or strike helicopter. It is mainly used to attack ground, surface and underwater targets, escort transport helicopters, and can also conduct air combat with enemy helicopters. It has the characteristics of maneuverability and flexibility, rapid response, suitable for low-altitude and ultra-low-altitude approaching attacks, and can fire in motion and hovering state. Most of them belong to the army aviation unit, and it is a new type of aircraft for the aviation unit to carry out direct fire support. Helicopter gunships can be divided into two types: special type and multi-purpose type. The special Xingxing armed helicopter is specially designed for carrying out attack missions, its fuselage is narrow and long, and there are only two crew members in the cabin in front and behind or side by side, or even one crew member, and the combat capability is relatively strong; in addition to being used to carry out attack missions, multi-purpose armed helicopters can also be used for transportation, landing, and ambulance. Anti-tank warfare is one of the main uses of helicopter gunships, so helicopter gunships are also known as tank killers; when confronting tanks, they are obviously in an advantageous position in terms of field of view, speed, maneuverability, and weapon range. Carrier-based helicopter gunships can also expand the combat range of ships or fleets and enhance combat capabilities. Helicopter gunships generally carry a variety of weapons such as machine guns, aerial guns, bombs, rockets and missiles, with a maximum level flight speed of more than 300 kilometers per hour and a flight time of 2-3 hours. Helicopter gunships are widely used in modern local wars, play an important role in warfare, and have attracted great attention from all countries. The helicopter is basically an air transport unit, and it can carry 2 units onto any square in the range of action, regardless of whether there are enemy units nearby. Helicopters can only carry foot troops – not mechanized troops. A unique advantage of a helicopter over fixed-wing aircraft is that it can take off and land vertically, which allows the helicopter to perform missions in confined areas where runways cannot be built. Today, helicopters are used in civilian applications as a means of transport for rescue purposes or for law enforcement purposes. And helicopters have a variety of military uses, ranging from large transport aircraft to personnel carriers to fast-moving flying tanks, the latter of which mainly serves as a ground combat support supported by the air—" I read it with relish, those ancient people were confused, they didn't know what I was talking about, many words didn't know what they meant, they didn't know what they meant, and suddenly they heard a ping-pong sound outside, no, suddenly we remembered those people in red who were chasing after me, just so happy, carried away, and accidentally forgot their existence.
