So, does the article say it was placed on a plane? Or are we talking simulated high altitude tests? I'm no expert but wouldn't you need put a complete engine on an aircraft to test it, not just the core? I suppose you could, but I don't know if that was the path taken with the WS-10
高空台=高空模拟试车台 means the Simulated Altitude Test Facility .
