Torbernite 发布于2023年3月12日 发布于2023年3月12日 According to the memoir from Ge Wenyong, test pilot and instructor pilot of PLAAF, in early 1964 they tested the F-86F-30 brought by KMT surrender pilot, and found the hydraulic system worked at same pressure (3000 psi or 210 kgf/cm^2) with J-7 (the basic version, or in other words, MiG-21F-13), and the emergency hydraulic pump was same in appearance. While the hydraulic system of J-5 and J-6 or MiG-17/19 works at about 145 kgf/cm^2 and their hydraulic accessory was larger and heavier. Considering a relatively complete F-86 wreckage was captured in 1951, was its hydraulic design and equipment absorbed into MiG-21 design? Does anyone see my FF Su-27? It's about 22m in length and 15m in width. It should be here! I saw it just now! Anyone touched it? What? I'm dreaming?

MiG-21 hydraulic system peak pressure without any flow is rated 215 kg/m2, normal working pressure is 180kg/m2 with typical 35l/min flow (when pump is new, flow at end of pump's service life is about 25l/min). Here photo of F-86 emergency pump: Here emergency NP-25T pump from MiG-21 family: They looks completely different. Conclusion: F-86 wasn't eated by MiG-21.
