[問題] 推力,重量與極速
SR-71 的發動機最大推力只有34,000 lbX2
Loaded weight: 152,000 lb (69,000 kg)
推重比 0.4474
極速Mach 3.3(2,200+ mph, 3,530+ km/h) at 80,000 ft (24,000 m)
F-22的發動機最大推力35,000+ lbX2
Loaded weight: 64,460 lb (29,300 kg)
推重比1.0859
極速Mach 2.25 (1,500 mph, 2,410 km/h) [estimated]

為何推重比領先這麼多,極速卻反而慘輸呢?
順便問一下,假設飛行員穿太空衣並配備全套太空維生裝備,且不考慮安全性
F-22最高能升到幾公尺高呢?
