What are Flying Machines?

A flight vehicle is an instrument that flies in the atmosphere or in outer space (space). Aircraft fall into three categories: aircraft, spacecraft, rockets, and missiles. Those flying in the atmosphere are called aircraft, such as balloons, airships, and airplanes. They rely on the static buoyancy of air or the aerodynamics of relative air movement to fly. Those flying in space are called spacecraft, such as artificial earth satellites, manned spacecraft, space probes, and space shuttles. Driven by the launch vehicle, they gain the necessary speed to enter space, and then rely on inertia to make orbital movements similar to celestial bodies. ^[1]

Historical development of aircraft

Humans have long had ideals of flying like birds in the air. The mechanical pigeons made by Architects of ancient Greece, the flying devices as far as Australia, the Chinese lanterns and kites are all related. In ancient China, some people described the ideal of flying in literary works, and others designed some large kite flying machines in an attempt to realize this ideal of breaking away from the shackles of the earth.

Aircraft , Designed a test of dozens of gunpowder rockets tied to a chair, flying with a kite in hand. The earliest flying machine in the world was the kite invented by China. In the 15th century, Leonardo Da Vinci of Italy also designed aircraft.

The development of modern aircraft has benefited from the huge leap in science and technology brought by the industrial revolution in the 19th century. In the 19th century, there were constant attempts to break through the shackles of air, but all failed. With the invention and widespread application of the internal combustion engine, flying in the air has gradually become possible. In 1903, the Wright brothers in the United States took the lead in manufacturing aircraft that could fly in the United States, and realized the dream of flying. Subsequently, aircraft and related science and technology have developed rapidly.

There are a lot of research institutes and even individuals on aerodynamic aircraft in foreign countries. But it is indeed a distant dream in China. With the development of the times, some people have boldly put forward some methods and methods, but as for the substantive progress, we have not seen that the American Martin Company has launched a high-profile single-person air Powered aircraft, and the list price is: 100,000 US dollars, and it is understood to have been equipped for: scientific exploration, marine, military, and so on. ^[2]

General classification of aircraft

There are five types of aircraft: aircraft, spacecraft, rockets, missiles, and guided weapons.

Aircraft flying in the atmosphere are called aircraft, such as balloons, gliders, airships, airplanes, helicopters, and so on. They rely on

Ground effect aircraft Aerodynamic lift-off from static buoyancy of air or relative air movement.

Spacecraft flying in space are called spacecraft, such as artificial earth satellites, manned spacecraft, space probes, and space shuttles. They get the necessary speed into space under the impetus of a launch vehicle, and then complete orbital motion under the influence of gravity.

Rockets are rocket-powered aircraft that can fly in or out of the atmosphere.

Missiles are controllable rockets equipped with a warhead. There are ballistic missiles that mainly fly outside the atmosphere, and surface-to-air missiles and cruise missiles with wings that fly in the atmosphere.

Guidance weapons are high-hit rate weapons that can be carried out in accordance with certain rules, flying in the atmosphere, such as terminal-sensitive bombs and guided artillery shells.

Aircraft World War II Saucer

During World War II, Nazi Germany has begun secretly developing dish-shaped aircraft, and has already made prototypes that can fly. However, with the progress of the war, this "outstanding ancient imagination" has disappeared because of the Nazi's demise before it was publicized, leaving a mystery for future generations.

Mysterious Saucer

In the air battle at the end of World War II, the Allied pilots repeatedly found that there was a strangely shaped aircraft far away from the side of the German aircraft formation. The thing had a circular dish shape and no wings, but it was fast and flying. Excellent performance, able to steer and climb and dive sensitively, some pilots even claimed to have seen the UFO with the iron cross symbol-they are the symbol of the Third Reich, although the Allied Command received many witness reports, but There have been no reports of such mysterious vehicles attacking the Allies, they have simply passed by, or hovered silently.

The Allies have heard of top secret research in Nazi Germany. They have sent intelligence personnel to follow the troops into the enemy's realm, specifically collecting all scientific research information on German secret weapons. As a result, the Germans have shown amazing creativity in the war. . After seeing information on V-2 rockets, super tanks, long-range artillery, and jet fighters, a senior Allied general said, "The occupation of Nazi German scientific research institutions reveals the fact that we are in many areas of research Already far behind them ... "

Among the many technical data left by the German army, the Allies found a photo of an aircraft with a strange shape. This is a propeller aircraft with round wings, unlike any German aircraft in the past. In an abandoned warehouse, the Allies found its wreckage, which had been destroyed by the defeated German army, which was clearly a verification machine to test the maneuverability and aerodynamic characteristics of the circular aircraft. The circular aircraft has many advantages. First of all, its center of mass is especially suitable for vertical takeoff and landing technology. Secondly, it has a certain stealth effect under the irradiation of radar waves. If the power and control problems can be solved, then this shape of the aircraft will have extremely flexible maneuverability, and it will be a terrible air combat weapon after adding weapons.

Secret development ends without results

Nazi Germany's research on saucer aircraft began in the 1920s, when some avid Nazis tried to find a powerful energy source to make time machines to communicate with ancient gods. There is no doubt that these attempts were futile, but they have produced a by-product-suspension power system. For many years since then, Nazi Germany has been conducting a lot of research on this type of aircraft, and some people think that they have made breakthrough progress in the research of the flying saucer's power system.

In 1952, a former Luftwaffe captain and aviation expert Strelivo announced that he had drawn a blueprint for a saucer aircraft near Prague. The test model of the blueprint was completed in 1944 and is expected to be tested in 1945. The rapid advance of the army made all this happen. On the eve of the collapse of the Third Reich, information such as design blueprints was lost. This fabulous aircraft with a design speed of 2600 kilometers per hour has never been searched. After Strelivo's death, in his relics, people really found design sketches about flying saucers! This casts another layer of mystery on this aircraft.

The Nazi UFO seems to be dead, but some people claim to have witnessed the test flight of this bizarre aircraft. It is said that the performance of the aircraft is very good, it climbed about 9,000 meters in 3 minutes, and the speed reached hundreds of kilometers per hour. The witness, George Klein, had something intriguing in his statement: he said that some research work was arranged at the Peneminde base, which is the top aerospace scientific research organization for the Nazis studying top-secret weapons such as missiles. He also confirmed that the flying saucer achieved good stability by using the spin method. Also, he said that the UFO test flight was in the Harz Mountains, and this is exactly where the UFO witnesses reported! . Nuclear power, as the most powerful energy source discovered by mankind, is the best choice for aircraft. There is also a wireless transmission system that can use microwave or laser as a dish-shaped aircraft to deliver a steady stream of energy. Many countries are scrambling to develop wireless power transmission technologies.

U.S. saucer

In 1955, Hill Company of the United States introduced a dish-shaped aircraft called a VZ-1 flying platform, equipped with two engines each with a power of 30 kilowatts, and a flight speed of 24 kilometers per hour. In 1980, the American Moore Corporation developed a two-seat XM-4 frisbee with a ducted fan. Four engines with a power of 30 kW each drove eight ducted fans to jet downward to generate lift. In 1987, the US Sikorsky company began to develop a coaxial rotor-shaped dish. The two rotors were coaxial, and the two rotors were rotated opposite to each other. The power unit can be a gas turbine, a gasoline engine or an electric motor.

The United States has also developed a dish-shaped aircraft with a fixed disk-shaped wing. Its radial section is wing-shaped and can generate lift. There is also a saucer with a rotating ring. Its ring is rotating, which can make the flight more stable.

A saucer-shaped aircraft includes a cockpit, a fixed base, a landing gear, wheels, an engine, and a control device. An annular groove is formed at the connection between the cockpit and the fixed base, and the inner ring of the dish-shaped casing is sleeved into the groove. There are two rotors symmetrically arranged on the dish-shaped housing. The rotors are connected to the rotor switch control device. The engine is connected to the transfer case through a clutch. The first output shaft of the transfer case is connected to the drive shaft of the dish-shaped case through a conical gear set. The drive gear at the upper end of the drive shaft of the dish-shaped housing meshes with the internal teeth on the inner ring of the dish-shaped housing, the second output shaft of the transfer case is connected to the propeller shaft through three constant velocity universal joints, and the propeller shaft is fixedly connected to the propeller A rotatable disk is arranged on the inner wall of the fixed base, a bearing seat fixed on the edge of the disk is sleeved on the propeller shaft, and the disk is connected to a disk operating lever in the cabin through a connecting rod. The technology is convenient to operate, and can integrate three functions of cars, ships, and airplanes to achieve amphibious travel.

Aircraft hyperlight curvature aircraft will subvert the space industry is true

Despite the enthusiasm of previous media reports, NASA officials stressed that NASA has not yet reached the point where it can develop a fuel-free, super-light propulsion system. Why is this news so compelling? Because this magical new type of thruster mainly relies on the microwave relativity engine (EmDrive), the British inventor claims that the engine can generate thrust without applying any thruster, relying on the microwave in the engine's internal cavity. If this engine can be used, it will upend the aerospace community and obviously violate the laws of physics ^[5] .

"Although NASA's Houston Johnson Space Center's theoretical research on new propulsion methods has created a large wave of news headlines, this is only a small attempt, and so far no practical results have appeared," NASA officials at Said in the interview. "NASA is not working on 'curvature thrusters' ^[5] ."

This new type of thruster seems to be able to produce more energy than it has, which violates the law of conservation of energy. Astronomer physicist Brian Koberlein, who studies general relativity and computational astrophysics at the Rochester Institute of Technology, said: "(The concept) is controversial because it violates Newton's third law." Later Koberlein mentioned, perhaps The electromagnetic leak in the internal cavity of the engine or the coupling with the earth's magnetic field can provide a possible explanation for it. However, recent tests in a vacuum environment have at least ruled out that the thruster does not move the earth's atmosphere by pushing it ^[5] .

Other related scientists are of course very keen to know what Paul March of Johnson Space Center Eagleworks successfully achieved and how to do it, but the research has not been open to peer review so far, and they cannot make more specific assessments. ^[5] .
