A turbo-compounded engine includes a piston engine connected to drive a propulsor. An outlet of the piston engine is operable to connect products of combustion from the piston engine to pass over a turbine. The turbine is connected to drive a turbine shaft also connected to drive the propulsor. An outlet of the turbine is connected into an exhaust duct configured to exhaust the products of combustion. The exhaust duct is provided with an exhaust duct outer wall defining an exhaust chamber. A further cooling air outer wall is positioned outwardly of the exhaust duct. Flow dividers are received within an exhaust chamber inward of the exhaust duct outer wall. The exhaust duct outer wall has an inner surface and the flow dividers have an outer surface. Acoustic treatment is provided on both the inner surface of the exhaust duct outer wall and the outer surface of the flow dividers.

Engine-wise this is achieved with the combustion engine (35). The drawings illustrate the left propulsion set (31) established as a Turbo-Compound engine, whereas the internal combustion engine is designed to a compound cycle engine. It comprises a gas turbine engine (36) with a turbine power shaft (361), a compressor (362), a combustion chamber (363) and a turbine (364) driving the compressor. The compound cycle engine further comprises a piston type engine (38) with an engine air intake (381), crank shaft (382) and a piston engine rotor driving (383) the crank shaft (382). Furthermore, the gearbox (37) couples the gas turbine engine (36) with the piston engine (38) to transfer power from the power shaft (361) and the crank shaft (382) to the propulsor (33) and electric generator (342). Both the gas turbine engine (36) and the piston engine (38) are configured to feed bleed air from the compressor (362) to the piston engine air intake (381) and to feed exhaust gas from the piston engine (38) to the combustion chamber (363) of the gas turbine engine (36).

The utility model discloses rapid gas and liquid injection equipment, which relates to the field of counter-recoil machine maintenance equipment, and adopts the technical scheme that the rapid gas and liquid injection equipment comprises a liquid injection cylinder, a nitrogen source, a first reversing valve and a second reversing valve, two ends of the liquid injection cylinder are respectively a gas inlet end and a liquid outlet end, the end face of the gas inlet end is provided with a gas inlet, the end face of the liquid outlet end is provided with a liquid outlet and a liquid inlet, and the liquid inlet is provided with a liquid inlet valve; a piston and a spring are arranged in the liquid injection cylinder, and the spring pushes the piston to slide towards the air inlet end; the nitrogen source is communicated with an inlet of the first reversing valve, a first outlet of the first reversing valve is communicated to the gas inlet, a second outlet of the first reversing valve is communicated with a first inlet of the second reversing valve, a second inlet of the second reversing valve is communicated with the liquid outlet, and the liquid outlet is communicated with the liquid inlet. And an outlet conversion tool of the second reversing valve is connected with an air tap. And liquid injection and gas injection are integrated together, tools do not need to be replaced in the midway, efficiency is higher, and more convenience is achieved.
