虽然网络上一些视频已经证明了中美双方的F-22和歼-20飞机都具有超机动能力,但这只是直观上的感受,还需要进行客观的量化分析。美国F-22的基本数据已经公开,我国歼-20飞机的基本数据仍未公开报道,要讨论双方飞机的飞行性能,有必要对歼-20进行基本数据的估算。基本尺寸和重量参数估算结合网络上大量的歼-20和 Although some videos on the Internet have proven that the F-22 and F-20 aircraft on both sides of China and the United States have super-maneuver capability, this is only an intuitive feeling and requires objective quantitative analysis. The basic data of the U.S. F-22 has been made public. The basic data of China’s F-20 aircraft have not been reported yet. To discuss the flight performance of both aircraft, it is necessary to estimate the basic data of the F-20. Estimates of basic dimensions and weight parameters combined with a large number of F-20 and F-networks on the network
