The bomb load is large and the voyage is fun. The bombing of B-52 is called carpet bombing, just like lifting a carpet on the ground! The United States has been making progress for so many years, which shows that new energy is very good! The B-52 has a captain of 49.05m, a wingspan of 56.39m, a height of 12.40m, a wing area of 37 1.5m 2 and a total weight of 22 1350.

Kg, the maximum oil load179430l (with two auxiliary fuel tanks), that is, about135t. The total takeoff weight of the aircraft is 22 1.35 tons, and it can carry 27 tons of bombs. It is by far the heaviest bomber in America. The power part consists of eight Pratt & Whitney TF33-P-3/ 103 turbofan engines, which are hoisted in four groups under the wings on both sides with a thrust of 75.7 N (7720kg). General layout of slender fuselage with rounded rectangular section, swept wing with high aspect ratio and single vertical tail. There is little difference in appearance between each type. Its maximum flight speed is 10 10 km/h (height is 12200 m), its service ceiling is 16800 m, and its maximum fuel range is 16 100 km (without air). The development plan of B-52 can be traced back to the late 1940s and early 1950s. At that time, the tactical and technical requirements of the US military were: having an intercontinental voyage and being able to carry out strategic nuclear bombing missions at high altitude and high speed. The intercontinental voyage requires at least 10000 km endurance; The so-called high altitude is to be able to fight above 12000 meters; The so-called high speed, that is, the high subsonic speed around 1000 km/h, because the fastest plane flying by its opponent in the Soviet Union at that time was the MiG-17 fighter, and the maximum flight speed was such an order of magnitude. Under this technical background, the B-52 bomber is an excellent bomber that can fully meet the design and use requirements and can perform nuclear bombing tasks. It has incomparable long-range endurance and formidable bomb load. Because the ceiling of B-52 can be in the stratosphere of the earth, the nickname "Stratospheric Fortress" followed, which was once the pride of the United States. Wonderful photos of B-52 bomber (18 photos) With the rapid development of science and technology, new air defense systems and aviation equipment are constantly emerging, and B-52 bombing is gradually lagging behind. Because of its huge size and huge target, its radar cross-sectional area is nearly 100 square meter. The enemy's advanced ground air defense radar and airborne early warning aircraft can find them from 400 to 500 kilometers away. 10000 meters flying altitude, 700-800 km/h slow penetration speed, can only drop bombs horizontally, not good at maneuvering, making it an easy prey for modern air defense weapons. If the bomber can only be equipped with medium and short-range air-to-air missiles and anti-aircraft guns, it will be ruthlessly shot down by the other side before approaching the target; Surface-to-air missiles located around and within the target area, which can attack high, medium and low-altitude airspace targets, will make them doomed; Even those antiaircraft guns linked with air defense radar, with a range of 10000 meters and dense defense, will cause fatal blows to them. This is a threat to a large bomber like B-52 due to the rapid development and progress of supersonic interceptor fighters, air-to-air and surface-to-air missiles, airborne early warning aircraft and ground early warning radar since the 1960s and 1970s. At the same time, their main position in the strategic air force gradually gave way to the variable swept wing bomber B- 1B and the flying wing stealth bomber B-2. Their radar reflection cross-sectional area is small, and they can carry all kinds of weapons and penetrate at high speed, low altitude and ultra-low altitude or high altitude. The development of high technology made B-52 fall behind rapidly, but it did not make it quit the historical stage. Although the bomber is old, it still maintains the advantages of long range, large load and low price. The new generation bomber can't completely replace the B-52 bomber because of cost and technology problems. The United States used these specialties to modify new weapons and equipment, so that the B-52 reached an updated operational level.
