The hybrid concept of turboshaft engine working according to Humphrey cycle dedicated to variety power demand – CFD analysis

The paper presents a new concept of the turbine engine in area pressure gain combustion (PGE). works according to Humphrey’s cycle. Minor modification construction has allowed power generation 500 kW, 700 1000 and 1800 kW. successfully resolved challenges related temporary opening closing chamber. presented valve timing system ensured effective gas flow what stands behind it, an process conversion high-pressure impulse into mechanical energy. Rotating chambers enabled application sealing system. characterizes simple potentially low power-to-weight coefficient. CFD numerical analysis showed very promising efficiency specific fuel consumption.
