Current status of low pressure turbine component research in HYPR program

The propulsion system which is the object of the R&D program is a combined cycle engine consisting of a turbo jet engine which operates throughout from take off to flight at around Mach 3 and a ram jet engine which operates throughout from Mach 2.5 to Mach 5. In order to demonstrate the feasibility of the turbo engine system , a subscale engine demonstrator of approx. 1/3 scale was designed, manufactured and tested. The engine is designed and fabricated by a consortium of domestic and overseas engine manufacturers. MHI is responsible for the low pressure system components including fan, low
