Jfem Boeing hires pilots to assist customers with Max and other models: report
Engineers from Naval Air Systems Command NAVAIR helped Sikorsky solve the CH-53K King Stallion heavy-lift helicopters gas re-ingestion problem.The US Marine Corps USMC helicopter gets its heavy lifting capacity from three General Electric T-408 engines, rated at 7,500shp 5,520kW each. However, Sikorsky has struggled to integrate the big engines, with exhaust gas re-ingestion being the most troublesome issue, NAVAIR says on 17 December.Source: NAVAIRSikorsky CH-53K King Stallion undergoing exhaust re-ingestion testing using colored oil smoke to indicate rotor wake and wind effects <Exhaust>gas re-ingestion] occurs when the hot engine gasses are ingested back into the system, says Debbie Cleavenger, the H-53 helicopter programme offices chief engineer.
