When did cars and planes appear?

1769, Frenchman N·J· kugnot made the world's first steam-driven tricycle. 1879, German engineer karl benz successfully tested the two-stroke experimental engine for the first time. 1June, 883, founded "Ben Ci Company and Rheinland Gas Engine Factory". 1in June, 885, he manufactured the first Ben Ci patented motor vehicle in Mannheim, which was a three-wheeled vehicle with a two-stroke single-cylinder gasoline engine of 0.9 HP. This car has some basic characteristics of modern cars, such as spark ignition, water cooling cycle and steel tube frame. 08861Oct 29th 65438+65438 German engineer karl benz is karl benz.

This car has been patented. In June 5438+10 of the same year, Karl Benz's three-wheeled motor vehicle obtained a German patent (patent number: 37435a). This is considered to be the first modern car in the world. For the above reasons, people generally take 1886 as the first year of automobile, and some scholars take the year when Carl Benz made the first three-wheeled automobile (1885) as the year when the automobile was born.

The French believe that the earliest airplane in the world was invented by the Frenchman Clemente Ade, and it was successfully tested in France on June 9, 1990. Some people think that he invented the first airplane in history. Americans believe that the inventors of the plane were American brothers wilbur wright and Orville Wright, who successfully tested in the United States on June1903+February 17. Brazilians believe that Alberto Santos-dumont invented the airplane. Santos-Dumont's "14 bis" aircraft successfully flew to an altitude of 60 meters on June 1906+ 10/2, which was the first successful power flight in the world. It is generally believed that the American Wright brothers invented the airplane, and some people think that it was invented by Clement Adel or Alberto Santos dumont. 1903 the plane designed and manufactured by Wright brothers of the United States successfully flew, which is the first time in the world to realize the dynamic maneuvering flight of an aircraft heavier than air. During World War I, airplanes were already used in combat, and they were made in Nanchang at that time.

The altitude reached 180 ~ 220km/h, the ceiling was 6000 ~ 7000m, the range was 400 ~ 450km, and the bomber's bomb load was 1000 ~ 2000kg. In World War II, the speed of aircraft reached 750 km/h, and the bomb load of bombers could reach about 10 tons. After the mid-1940s, the engine developed from piston to jet, and the flight performance of aircraft was significantly improved. In the 1980s, the ceiling of the aircraft has exceeded 30,000 meters, the maximum speed has exceeded 3 times the speed of sound, the range has exceeded 20,000 kilometers, and the maximum payload has exceeded100t.
