Since I can only pass a **, I only inserted the aircraft of the First World War, this kind of aircraft is generally a biplane (as shown in the picture) or monoplane-based, the fuselage is generally made of wood, the weight of the fuselage is large, at the same time, the cockpit is exposed so that the aircraft does not fly high, flying not fast, the aircraft of World War II are generally made of metal, not alloy, although the strength is stronger than the aircraft of the First World War, but the weight is heavier, and all the air actions of the aircraft of the Second World War are due to the absence of a hydraulic power system, or a hydraulic servo system, After World War II, civil aviation began to develop vigorously, and the flight speed has also been significantly improved, and the aircraft can change the aspect ratio to change the flight speed (aspect ratio: the area of the large wing of the aircraft is the ratio of the connection line of the wingspan of the large wing and the two wingtips of the large wing) The greater the aspect ratio, the greater the flight speed, you can compare the Concorde aircraft, his aspect ratio is very large, he is a supersonic passenger aircraft. At the same time, modern civil aircraft are generally transmitted by wire, hydraulic transmission, steel cable transmission mode to drive the pilot's control signal, greatly reducing the physical load of the pilot, and the modern aircraft is very intelligent, humanized, basically all the problems in the sky can be solved for the pilot, even if the pilot falls asleep in the air cruising stage, it doesn't matter. >>>More
