The B-52 has gone through many improvements and upgrades from the initial prototype to the current H-type aircraft. The first prototype, code-named XB-52, left the factory in November 1951 and took flight in October 1952.
Because jet aircraft were a relatively new thing at the time, major powers were competing to develop jet aircraft. However, due to technical reasons, no engine with a large bypass ratio has been developed. The use of mature small bypass ratio turbojet engines can only be limited. And because the fuselage is huge and the tactical expectations are high, 8 more engines are installed. When it takes off You can see the billowing smoke. It's really spectacular. Later, the United States wanted to revive the old school. However, due to the changes that had a great impact on the wings and financial issues, only the internal electronic equipment was changed. No changes were made to the engine. There have been too many changes. So today’s B-52Hs are still flying with 8 rounds. However, this can also meet the needs of the military. So you can still see it now
My help does not need to be repaid, I just hope You give me a promise. When others need help, please help them.
Professional passing
