There is a huge problem in using proxy and related formulas to calculate missile range. That is, the precise aerodynamic data of aircraft, including aircraft and missiles, must be measured by proportional models in wind tunnel experiments, because in fact, this is an empirical formula. The simulation calculation actually has a huge error in the calculation of aerodynamics and cannot be used as normal auxiliary design data.
As I pointed out, the range of PL-17 given in the video is 400km,
but in fact, the PL-17 related papers given by the Chinese Air Force clearly marked the range as 500km.
