The process of human exploration of flight
Mankind's exploration of flight had gone through a long process. During the ancient civilization, humans had a yearning for flight. The ancient Chinese invented the kite, which was used for war communication and reconnaissance. Later, it developed into an entertainment activity, and kites were also used by aviation scientists for flight experiments. Hiro of Alexandria, an ancient Greek engineer, invented the spinning ball and studied the use of air pressure and steam to create power. In terms of aviation theory, Leonardo da Vinci conducted early research on flight. His Principles of Bird Flight contained many notes and sketches about the nature of flight and the principles of flutter, laying the foundation for the development of aviation. In 1809 - 1810, Sir George Kelly of the United Kingdom published On Air Guidance, which determined the four forces of flight (gravity, lift, drag, and thrust). In terms of flight practice, on November 21st, 1783, the balloon designed by the French brothers Joseph Michels and Jacques Mongovier was tested for the first time on a manned animal. Subsequently, the competitor's hydrogen driven balloon flew farther and longer. In 1809, George Kelly, an Englishman, made some achievements in the trial production of gliders; in 1871, Peno, a Frenchman, invented an aircraft model that could fly stably; in 1890, Adel, a Frenchman, developed a power plane with a steam engine and successfully took off horizontally. On December 17, 1903, the Wright brothers piloted the "Flyer 1" to complete the first manned powered flight of mankind, creating the era of flight. In 1909, Feng Ru completed the "Feng Ru 1" designed and manufactured by the China and successfully tested it. After the appearance of the aircraft, in the military field, the aircraft was relatively simple in the early days of World War I, mainly responsible for reconnaissance missions in the theater of operations. Later, it gradually developed into carrying weapons for air combat, carrying out bombing missions, etc. After the baptism of World War I and World War II, the aircraft's appearance structure, manufacturing materials, performance and other aspects continued to develop and reform. For example, from biplanes and triplanes to single-wing aircraft, the manufacturing materials developed from wood to aluminum alloy, etc. In the civilian field, the surplus military bomber after World War I was first converted into civilian aircraft. It was first used for cargo transportation and then developed to carry passengers. The emergence of jet propulsion technology promoted the development of civilian aircraft. For example, in 1949, the United Kingdom developed the "Comet" medium-range jet passenger aircraft. Since the 20th century, human flight exploration had gradually developed from flying high above the Earth to space exploration. For example, an aircraft like Voyager 1 had flown to a place 24 billion kilometers away from Earth. The novel "Hundred Years of Spaceship" is equally exciting.

Enumerate human exploration of flight
Mankind's exploration of flight was rich and varied. In ancient times, the ancient greeks invented a flying toy called "Caravel" in the 4th century B.C. In medieval Europe, people used bird feathers as wings to try to fly. In ancient China, kites, rockets, Kongming lanterns, bamboo dragonflies, etc. were invented, which were considered the prototype of modern aircraft. The myth of Chang'e flying to the moon reflected the ancient people's yearning for flight. From the end of the 18th century to the beginning of the 19th century, the Frenchman, Etian Gaspard, designed the early hot air balloon,"La Minerve." In 1783, the French Mongolfe brothers made a hot air balloon that could carry people. In the same year, Rosier flew over the Palace of Versailles in a hot air balloon for 25 minutes, starting the "air age" of mankind. At the end of the 19th century, the Wright brothers were inspired by toy helicopters and conducted a series of experiments in North Caroline between 1900 and 1903. They built gliders and test flights, mastered the basic principles of flight, and invented flight control technology. On December 17, 1903, Orville piloted the "Flyer 1" to fly 120 feet (about 36 meters) for 12 seconds, completing the first powered flight in human history. In 1905, the "Flyer 3" successfully flew for 39 minutes, covering a distance of more than 24 kilometers. In the 20th century, aircraft changed from wooden biplanes to metal single-wing jets. The rise of military aircraft and civil aviation promoted the development of flight technology. The space race after World War II gave birth to rocket technology and space exploration. In 1957, the Soviet Union launched the first man-made Earth satellite. In 1961, the Soviet pilot Yuri Gagalin became the first person to enter space on the Vostok spacecraft. In the 21st century, human flight exploration was no longer limited to the Earth's atmosphere. Deep space probes such as the Rosetta were successfully launched and carried out missions. Humans could reach asteroids and comets in the solar system for on-site exploration. Manned space flight was becoming more and more normal. The International Space Station became a long-term residential and scientific research platform in space. Private companies such as SpaceX made commercial space flight and space travel possible.

The History of Human Exploration and Flight
* * Title: Human Exploration of Flight ** Flying had always been a dream filled with fantasy and desire in the hearts of humans. From ancient legends to modern high-tech aircraft, mankind's exploration of flight had gone through a long and winding process. In ancient times, the dream of flying had already been reflected in myths and legends. In ancient Egyptian mythology, the goddess Isis had wings to soar in the sky. In ancient Greek legend, Daedalus and his son Icarus used feathers and wax to make wings and tried to fly over the Aegean Sea. These legends reflected the early human yearning and initial imagination for flight. In ancient China, kites were considered the first form of man-made aircraft. Legend has it that they were invented by Mozi and improved by Lu Ban. Wooden kites were used as communication and detective tools in wars. There was also the Sky Lantern (Kongming Lantern), which was said to have been invented by Zhuge Liang. Its principle was the same as that of a hot air balloon, and it had many military uses in ancient times. In ancient times, there were also some "flying men" who tried to fly by themselves. Although most of their attempts ended in failure, this brave spirit of exploration took the first step for flight exploration. As time passed, the ornithopter appeared after the 17th century. Da Vinci was particularly famous for his research in this area. His manuscripts and sketches provided the theoretical basis for the development of aircraft. The ornithopter was an important stage in the transition from ancient flying people to modern aircraft. The year 1783 was an important year in the history of flight. The Mongolfi brothers carried out the world's first manned flight in a hot air balloon. The balloon flew in the air for 25 minutes. This event opened a new era for humans to use buoyancy to fly. Two months later, their competitors also conducted further flight tests, such as flying longer distances and longer times in hydrogen balloons. At the beginning of the 19th century, Sir George Kelly published "On Air Navigation", which determined the four forces of flight (gravity, lift, drag, and thrust), proposed the concept of fixed-wing aircraft, and designed a manned glider, introducing the world into the study of aerospace. In 1852, Henry Gifal piloted an airship to complete the first flight with controllable power, proving the possibility of powered air travel. In 1876, the internal combustion engine designed by Nicholas Otto laid the foundation for the new era of aviation. In 1903, the Wright brothers took off from Kitty Hawk, North Caroline, and made the first controlled, continuous flight. Although each flight was short, this feat opened the era of human freedom in the sky. Less than six years later, Feng Ru completed the test flight of the aircraft he designed and manufactured in China, Feng Ru No. 1. Soon after the aircraft appeared, it was used in war. During World War I and World War II, it was unprecedentedly developed. From the initial simple reconnaissance aircraft to fighter aircraft and heavy bomber equipped with weapons, the structure and performance of the aircraft were constantly improved. Since the 20th century, aviation technology continued to develop rapidly, and helicopters began to gradually develop and improve. In terms of space exploration, the Voyager 1 probe had been flying for 47 years. Although it would take about 30,000 years to completely fly out of the solar system, it also represented the efforts of humans to explore space on a larger scale. From ancient fantasies and initial attempts, to modern scientific theory research and continuous innovation of aircraft, and then to the great achievements of modern aerospace, the journey of human exploration and flight reflected the great spirit of human beings to constantly pursue dreams, bravely explore innovation, and break through themselves. This process also showed that with the continuous advancement of science and technology, human exploration of flight would continue to develop. In the future, there might be more unimaginable flight technologies and achievements. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
Lilienthal's Exploration of Flight
In the 19th century, George Kelly, a British expert in air dynamics, published On Air Voyage, which was regarded as a symbol of the birth of modern aviation. Lilienthal's glider absorbed George Kelly's idea. In 1891, the German engineer Otto Lilienthal started the glider era in the history of human aviation. He drove a 5.5-meter-long bird-shaped glider, which made it possible for humans to fly without power. Since then, he had experienced thousands of experiments. In 1894, he piloted a glider to fly as far as 1000 meters. However, in 1896, he was seriously injured and died in a flight accident. People erected a monument for him with the words "The Greatest Teacher". The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
The History of Human Flight
The history of human flight was a history full of dreams, exploration, and innovation. In ancient times, flying mainly existed in legends. In ancient Egypt, there was a legend of the goddess Isis soaring in the sky to protect her subjects. In ancient Greece, Daedalus and his son Icarus made wings of feathers and wax to fly across the Aegean Sea. In China, kites could be the prototype of man-made airplanes. Legend has it that they were invented by Mozi and improved by Lu Ban. The ancient wooden kite was used for communication and detective in war, and could even carry gunpowder to attack. The sky lantern (Kongming Lantern) was said to have been invented by Zhuge Liang. The principle was the same as that of hot air balloons. In ancient times, it was used for military signals, and in modern times, it was used for blessing. In ancient times, there were also flying people who tried to fly. Although most of them failed, they took the first step in human flight exploration. After the 17th century, Da Vinci's research on the ornithopter was a major advancement in the history of aviation. He left behind many manuscripts and sketches based on the observation of birds. However, the practical ornithopter was not actually manufactured, but gliders were derived from experiments. Otto Lilindahl was an important pioneer in glider research. He flew fixed-wing gliders many times. In 1783, the Mongolfei brothers made the world's first manned hot air balloon flight, which lasted 25 minutes. In 1896, the American inventor Samuel Pierpont Langley conducted a successful test flight of the unmanned aircraft model "space station." This was the first time that an aircraft with a gravity greater than air flew continuously. In 1900, the world's first airship, the Zeppelin LZ1, flew in Germany. In 1903, the Wright brothers successfully tested the "Flyer One", which was the first powered, manned, sustained, stable, and controllable biplane in human history. In 1909, the Frenchman Blelio flew across the English Channel for the first time in a single-wing plane. In 1919, Hugo Junkers of Germany successfully tested the world's first all-metal passenger plane, Junkers F.13. There were many innovative aspects in the design of the aircraft. In 1927, the American pilot, Lindberg, completed the first solo trans-Atlantic flight. In 1930, Frank Whitt of the United Kingdom obtained a patent for a gas turbine engine. In 1933, the American Lin Bai flew across the Atlantic Ocean for the first time without landing. In 1939, Germany successfully tested the first jet He178 single-wing aircraft. In the same year, Igor Sikowski's VS - 300 helicopter made its first successful flight. This was the world's first truly practical helicopter. In 1947, test pilot Charles Yaeger flew the X - 1 aircraft for the first time to break the sound barrier. In modern times, various countries were still researching personal flying devices. Although they had achieved some results, they still faced many challenges in terms of endurance, load, noise, safety, and cost. However, with the continuous advancement of science and technology, the development prospects of human flight were still broad. The novel "Hundred Years of Spaceship" is equally exciting.

The History of Human Flight
Mankind's exploration of flight had a long history and was full of challenges. In ancient times, the dream of flying had existed in various cultures. For example, in Greek mythology, Icarus and Dadaros used artificial wings to fly. Although they ended in failure, they reflected the human desire for flight. In China, around 400 B.C., Mozi and Luban invented the kite, a man-made flying device. At the same time, Chinese toy manufacturers also invented bamboo helicopters. The ancients also discovered the basic mechanism of hot air balloons and invented floating paper lanterns. In the Middle Ages, Leonardo da Vinci proposed the theory that bird-shaped wings could carry people, but it encountered difficulties in terms of power. In the 18th century, the French brothers, Josef-Michele and Jacques - Étienne Montgolfier, created the first hot air balloon that could support the weight of a human. They flew five miles over France on November 21, 1783, and demonstrated their hot air balloon. At the turn of the 19th century, the British engineer George Kelly published the paper "Air Navigation" to lay the foundation for the study of flutter. About 70 years later, Nicholas Horta created the world's first gas-powered internal combustion engine. On December 17th, 1903, the Wright brothers 'first airplane made a historic test flight. Although the brothers' flight time was only 12 seconds and 59 seconds respectively, this was the first controlled flight in human history. World War I pushed forward the development of aircraft technology, including the introduction of more powerful engines, improved wing designs, and more stable flight control systems. In the 20th century, airplanes developed rapidly. At the age of 25, Charles Lindberg completed a trans-Atlantic flight from New York City to Paris. The design of aircraft continued to vary, from biplanes to single-wing aircraft, then to jets and modern supersonic aircraft. The introduction of jets greatly reduced travel time, and the rise of commercial aviation made aircraft the main means of transportation. Today, the emergence of drones brought new possibilities to the aviation field, and researchers were also exploring more eco-friendly aircraft designs to reduce the impact on the environment.

The process of human evolution
Human evolution originated from the forest apes, and gradually developed from primates through a long evolutionary process. It went through four stages: ape humans, primitive humans, intelligent humans, and modern humans. About 65 million years ago, a meteorite with a width of about 16 kilometers hit Earth (the Yucatan Peninsula in Mexico), causing the extinction of two-thirds of animal species, including dinosaurs. Primitive mammals survived and rapidly evolved. About 50 million years ago, primates evolved rapidly, from low-level primates to high-level primates. 33 to 24 million years ago, apes were born from the monkeys of the Old World. Among them, there were ancient apes such as the Aepians (30 million years ago), the Aepians (26 to 28 million years ago), the Dryopians (23 to 10 million years ago), and the Pro-Consulians of East Africa (13 to 12 million years ago). These ancient apes were mostly tree-climbing apes that lived in forests and walked on all fours. The existing apes are divided into African apes (gorillas, chimpanzees, and humans) and Asian apes (gibbon and orangutans), which diverged between 12 million and 15 million years ago. From about 10 million years ago to about 3.8 or more than 2 million years ago, Ramapetus and Auropithecus were fossil representatives of the transition period (although Ramapetus was relatively reasonable as a transition representative). In order to survive, the southern apes, which evolved from the ground apes, began to migrate. They already knew how to use tools and became the overlords of the African grasslands. It was not until the emergence of Homo Erectus 1.8 million years ago that there was almost no excess fat in its body. It ran fast and patiently tracked its prey. After eating high-fat meat, its brain capacity gradually expanded. It also understood mutual understanding and co-survival. Then it moved to a wider world, and Asia and Europe gradually became covered with human footprints. In the process of evolution, the structure of the human body was constantly changing. For example, the number of fingers in humans was five, which might have been preserved in ancient times to meet the needs of survival and development. In the past, men with high Testosterone-level were respected for their physical strength, but in modern society, high Testosterone-level was inverse to the degree of investment in raising children. The human jaw deteriorated with the change of food processing methods. From the strong jaw of ancestors to deal with coarse food, to the gradual deterioration of the jaw due to the use of fire, the popularity of modern industrial food further accelerated this process, resulting in the reduction of jaw space of modern people and the growth of wisdom teeth. The human body temperature dropped by about 0.03 degrees Celsius every ten years, which may be related to the improvement of the modern social environment, medical progress, the reduction of the threat of disease, and the reduction of the need for high body temperature. Human bones began to become sparse after the change in lifestyle 12,000 years ago (from hunting and gathering to farming). The modern sedentary lifestyle continues this trend and may face a higher risk of fractures in the future. Human tolerance to milk products has been increasing. 20,000 years ago, most people were suffering from malnutrition when drinking milk. Now, about 35% of the population can easily digest milk, reflecting the improvement of human diet adaptability.
What are the human explorations of flight?
Mankind's exploration of flight was rich and varied. In the early days, ancient China had inventions such as kites and Kongming lanterns that embodied flight exploration. In the Middle Ages, some European inventor tried to imitate the flight of birds. From the end of the 18th century to the beginning of the 19th century, the Frenchman, Etienne Gaspard, designed the early hot air balloon "La Minerve" to open the exploration of using the principle of lighter than air to take off. At the end of the 19th century, the Wright brothers successfully created the world's first powered controllable aircraft," Flyer One," achieving the first powered and controllable continuous flight. This was a milestone in the history of aviation. In the 20th century, aircraft developed from wooden biplanes to metal single-wing jets. The rise of military aircraft and civil aviation promoted the advancement of flight technology. The space race gave birth to rocket technology and space exploration, allowing humans to escape the Earth's gravity and explore the universe. In the 21st century, human flight exploration was no longer limited to the Earth's atmosphere. Deep space probes such as the Rosetta could reach asteroids and comets in the solar system for on-site exploration and research. Manned space flight was becoming a norm. The International Space Station had become an important platform for long-term space residence and scientific research, and the participation of private companies made commercial space flight and space travel possible. In addition, humans were still exploring ways to achieve interstellar travel, such as antimatter engines, warp engines, nuclear fusion engines, and solar sailboats.
