Abstract

1413845 Marine propulsion ROLLS-ROYCE (1971) Ltd 13 Feb 1973 [11 Feb 1972] 6475/72 Heading B7V A water jet propulsion unit includes a turbine 22 which drives an impulse rotor 18 at the downstream end of a divergent/convergent portion 16 of the units' water flow duet. The turbine 22 is driven by gases from a combustion device 20 and the turbine exhaust gases are discharged through slots 36 into the water stream. The turbine and combustion device are contained in a body which is located within the water flow duct and which is fed with fuel and compressed air through a hollow strut 12. The source of compressed air may be a compressor driven by a gas generator, Fig. 5 (not shown). Alternatively, Figs. 6 and 7 (not shown), the source may be a gas turbine engine which may feed gas from an extra compression stage through a combustion device and a turbine. As a further alternative, Fig. 8 (not shown), compressed air is supplied by a pair of compressors connected in series with an intercooler. The compressors are driven by series connected turbines driven in turn by a gas generator.
