On the 8th of April, major news suddenly spread like wildfire on the Internet. The first domestic large-scale passenger aircraft C919 announced that it had broken the ban on sales of advanced engines by foreign companies into Z country. It had successfully achieved mass production! The news caused a flurry of heated discussions on the Internet. Many netizens did not believe this to be true.
"How is this possible? It has only been a short time since the sales ban was implemented!"
"They probably bought the engine from the Russians. This really is the fastest way to solve the problem."
"No, no! The news release said that the aircraft uses the domestic CJ-1000 large bypass ratio engine. The performances of its thrust, fuel consumption, working lifespan, and other functions are comparable to the LeapX engine produced by CFM International. Our domestic engine overcame the ban!"
"Impossible!"
