How can I fly higher? Fly high or fly high correctly

Flying with dreams and love can fly very high, as long as you work hard to make wings.

I'm sure you can.

It takes a power to support it, and hopefully you find the motivation to fly higher, and then plug in your wings and wish you to fly higher.

People are people, except for taking a plane, you just have to wait for n years later.

Fly high. Analysis: Most of the socks in front of "De" are words or words that indicate actions, followed by words or words that describe the state of things, indicating how, such as:

Walking fast, stepping on sparsely, screaming in pain, skinny skinny, red and purple, angry with his feet jumping, understanding very deeply, happy to close his mouth, stunned with surprise, very big, sweeping so clean, how sweet he laughs, so fly high and right.

The changes of the times of "of, land, and gain":of, land, and de" in the May Fourth Movement.

There was no strict distinction before, and there was often a phenomenon of mixing in old literature.

In Japanese, particles are used between body, quasi-body, and modifiers to indicate their persons.

Relationships, including the draft or adding meaning to the precedent words, occupy a very important position. It has no substance, cannot be used on its own, and has no conjugation. There are different opinions on the classification.

People go to high places, and water flows to low places." This is something we all know. Each of us has an ideal, and everyone has a pursuit.

We struggled little by little, and slowly rushed towards our ideals. A revered summit is to climb slowly, and the highest mountain in the world: Mount Everest.

It is more than 8,000 meters high, however, there are already people standing on its shoulders looking down on the world. However, not everyone can do it, and it is not very easy to climb it. If you want everyone to remember that you are admired by everyone, then you have to keep working hard to reach a high level.

Maybe we don't need to surpass others, we just need to surpass ourselves sometimes. We all know that the most terrible enemy in the world is none other than ourselves.

Surviving in this society, sometimes we feel happy, but sometimes we are sad, and most of us have to listen to others. Commanding, doing things for others, and there are penalties for not doing well, so there are many people who want to be bosses, because then you can stand and do nothing, and you can direct others to do things that you don't want to do.

There are very few geniuses, and everyone is not born to be a boss, nor is he born to work for others. We all come to this world equally, there is no distinction between high and low, only our own will and ideals control us. As long as you have ideals and strive for your ideals, then you will surpass yourself, be happier than others, and fly into the sky.

The reason why a bird can fly freely in the sky is because it has a pair of wings. We want to have a sky in our field where we can fly freely, and we must have a pair of long wings.

In fact, it is not difficult to fly, but if you want to fly higher, you must have a pair of wings that others do not have, and only in this way will you fly higher and farther than others. Nowadays we are building our own wings, learning knowledge in school, learning to be a man, laying the foundation for the future road, we want to be stronger than others, or others fly higher and farther, we must pay more efforts than others, so that we can surpass ourselves, surpass others, fly to a higher and greater sky, where we can create our own stool brilliance.

We want to celebrate Soola to fly higher, fly higher!

The pursuit of faster flight speed is one of the main lines of aircraft development.

For the first time in the late 40s of the last century, the speed of manned vehicles in the atmosphere exceeded the speed of sound. In the 60s of the last century, the American SR-71 "Blackbird" strategic reconnaissance aircraft and the Soviet MiG-25 interceptor reached 3 times the speed of sound. No matter how high-speed seepage aircraft appear, we will have to wait for a series of breakthroughs in cutting-edge aviation technology in the new century.

The so-called "hypersonic speed" means that the speed of an object exceeds 5 times the speed of sound, that is, more than 6,000 kilometers per hour. At present, there are three main types of hypersonic vehicles: one is a hypersonic cruise missile, the other is a hypersonic aircraft, and the third is a space shuttle that has been decommissioned by the United States.

The technical difficulties of hypersonic vehicles are, first of all, that they must be equipped with engines suitable for hypersonic flight. When the flight speed is greater than 5 times the speed of sound, the traditional turbojet and turbofan engines have reached the limit of their performance, and the efficiency of the engines has dropped sharply, unable to support hypersonic flight. Only a scramjet engine with a supersonic air intake speed can achieve hypersonic flight in the atmosphere.

The scramjet engine is mainly composed of an air intake, an isolation section, a combustion chamber and a tail nozzle. The air intake compresses the air through a series of shock wave systems, providing a certain flow, temperature, pressure to the combustion chamber and igniting the fuel. Its overall structure is relatively simple, but the speed of the aircraft itself must be in a hypersonic state before the engine can continue to work to propel the aircraft.

Another difficulty in achieving hypersonic flight is the problem of aerodynamic heating of the aircraft body, the so-called thermal barrier problem. When the aircraft is flying, due to the action of shock wave and viscosity, the temperature around the body rises sharply due to the violent friction, forming a violent aerodynamic heating environment. In the heat of thousands of degrees, the general aircraft structure simply cannot withstand it.

In order to overcome the thermal barrier, the aircraft needs to be specially designed for thermal protection. According to the different heat protection mechanisms, it can be divided into: heat sink heat protection, radiation heat protection, sweat cooling heat protection, and ablation heat protection.

As the combination of aviation and aerospace technology, hypersonic vehicle technology also involves hypersonic aerodynamics, computational fluid dynamics, high-temperature aerothermodynamics, chemical dynamics, navigation and control, electronic information, material structure, process manufacturing and other disciplines. It requires a high degree of integration of many cutting-edge technologies such as hypersonic propulsion, integrated design of airframe propulsion, supersonic combustion, thermal protection, endothermic hydrocarbon fuel, hypersonic ground simulation and flight test.

In recent years, scientific research institutions, universities and other research institutions in various countries have carried out extensive research on key technologies of hypersonic vehicles. Among them, the United States, Russia, Japan and China have all launched their own hypersonic vehicle demonstrators and carried out test flights. In the future military field, hyosonic vehicles are likely to be revolutionary equipment that will change the face of warfare.
