Anonymous users2024-02-04Boeing, is one of the world's largest manufacturers of civil and military aircraft. Boeing also provides support services for a wide range of military and civilian routes, with customers in more than 90 countries around the world. Boeing is one of the largest exporters in the United States in terms of sales.
On May 18, 2020, Boeing ranked 40th on the 2020 Fortune 500 list. Airbus, a European aircraft manufacturing and R&D company, was established in France in December 1970. Airbus's shares are 100% owned by the European Aerospace Defence Group (EADS).
In July 2019, the Fortune Global 500 list was released, and Airbus ranked 123rd.

Anonymous users2024-02-02The biggest one is Sikorsky.
The aviation giant is Boeing, and McDonnell Douglas has long been acquired by it.
Lo Mar's business is comprehensive and indistinguishable from Boeing.
The engine was made by Pratt & Whitney, or Pratt & Whitney for short.
Let's put it this way, aircraft manufacturing involves multiple companies and industries, both system integration and professional division of labor, which can be regarded as performing its own duties.
From the design, assessment, production, verification, transportation, testing, repair, maintenance, etc., this is a huge industrial system, not just by the power of a few giants can be completed, this scope has spread all over the world, has surpassed the United States.
Or our China Shilisuo, a Chinese aviation industry, all done.

The rest is not very clear.
This post has become a literacy sticker.
Ha ha. The world's first aircraft: the Wright brothers'. >>>More
Airplanes are heavier-than-air aircraft, so they need to expend their own power to gain lift. And the ** of lift is the effect of air on the wing in flight. The upper surface of the wing is curved and the lower surface is flat, so when the wing is in relative motion to the air, the air flowing through the upper surface travels a distance (s1) in the same time (t) than the air flowing through the lower surface (s2), so the relative velocity of the air on the upper surface is faster than the air on the lower surface (v1 = s1 t> v2 = s2 t1). >>>More
Purely in terms of size, the largest aircraft in the world is the Russian An-225 transport aircraft, its length and width (wingspan) are, while the Airbus A380 is per meter) and the maximum take-off weight, the An-225 is 600 tons, and some data say that the A380 is 590 tons, which is not much the same. You must know that the An-225 is the carrier aircraft of the Russian "Buran" space shuttle.
Navigation! Orientation can be determined. It's about the same as the nautical one!
Anyone who has learned about flow rate should know it. The pressure is small where the flow velocity is large, and the upper side of the wing is convex, so that a strong flow velocity can be generated when the aircraft is flying, the pressure is reduced, and the lower part is smooth, so the pressure is greater than the above, and the upward support force on the wing will be formed, which is the lift, if the aircraft thrust is greater, the lift will be greater.
