While the YF-23’s top speed remains classified to this day, defense analysts have claimed that it was better than Mach 2. However, the operational F-22 flying today beats both of those marks, with a top speed of Mach 2.25 and the ability to supercruise at Mach 1.82. ...

Both of the YF-23 and YF-22 are listed as similar speeds of Mach 2.25, however the F-22 shows superior supercruise speed at Mach 1.8 compared with the YF-23s 1.6. Speed at supercruise would prove extremely critical as it enables more dwell time over targets and an ability to maneuver ...

Although the system performance is low, the discharge temperature is also low, resulting in an advantage in terms of system protection at the same speed standard. Erdem et al. [18] conducted a performance analysis of R1234yf and R744 as alternatives to R134a. They built a model and ...
