这款发动机的参数也算是一流了, 日本喜欢小巧的? 推力换体积?

In 2019, Japan began testing XF-9-1 low-bypass turbofans developed by Ishikawa Heavy Industries. These can reportedly generate 11-12 tons dry thrust, or 15-16.5 tons ‘wet’ (dumping fuel into the afterburners) and tolerate 1,800 degrees Celsius of heat. While the F-22’s two F119 turbofans generate 13 tons dry and 17.5 wet thrust, the XF-9 is a half-meter shorter and 30 centimeters slimmer than the F-119, leaving more room for internal weapons.
