China’s online commenters seize on drop in F-22 engine performance data
Recent revisions on Wikipedia have significantly lowered the thrust-to-weight ratio of the Pratt & Whitney F119 engine, which powers the US military's F-22 Raptor, from 10 to 7. This adjustment has sparked debate, particularly in Chinese aerospace circles, regarding the engine's actual performance relative to initial expectations and its stated capabilities.
The revisions, supported by citations from a Rand technical report, research papers, and a US Air Force technical order, suggest that the F119's performance parameters, including thrust, fuel efficiency, and lifespan, may have been overstated. The changes reflect lower results for both intermediate power (5.2:1) and afterburner-engaged power (7:1), raising questions about the true capabilities of this crucial component of the F-22 Raptor.
