Abstract
Abstract A drive system is disclosed for increasing the total output power from a main driving and gas turbine engine combination. The subject drive system is particularly suitable for use in ships which include both a main driving engine such as a diesel or small turbine, having high efficiency at low power outputs, and a gas turbine engine, for high power outputs. In accordance with the subject invention, in order to obtain the maximum total power from both engines, the main driving engine is coupled to a compressor for supercharging air prior to its introduction into the gas turbine engine. The resulting horsepower generated by the supercharged gas turbine engine is greater than the sum of the horsepower of each individual engine.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
A drive system for supplying power to a propeller shaft of a ship comprising in combination: a main driving engine detachably coupled to said shaft for generating a low power output with high fuel efficiency; a gas turbine engine detachably coupled to said shaft, said gas turbine engine generating high power output; and a compressor detachably coupled to said main driving engine and fluidly communicating with said gas turbine engine to supply compressed air to the inlet thereof for increasing the power generated by said gas turbine engine, maximum total output power to the shaft being generated by detaching said main driving engine from said shaft and coupling said main driving engine to said compressor such that the power output generated by said main driving engine is utilized to drive said compressor, which functions to supercharge the air input to said gas turbine engine.
Claim 2
Dependent Claim
144 words
A drive system for supplying power to a propeller shaft of a ship comprising in combination: a main driving engine detachably coupled to said shaft for generating a low power output with high fuel efficiency; a gas turbine engine detachably coupled to said shaft, said gas turbine engine generating high power output; and a compressor detachably coupled to said main driving engine and fluidly communicating with said gas turbine engine to supply compressed air to the inlet thereof for increasing the power generated by said gas turbine engine, maximum total output power to the shaft being generated by detaching said main driving engine from said shaft and coupling said main driving engine to said compressor such that the power output generated by said main driving engine is utilized to drive said compressor, which functions to supercharge the air input to said gas turbine engine.
Claim 3
Dependent Claim
17 words
A drive system as recited in claim 1 wherein said main driving engine is a diesel engine.
Claim 4
Dependent Claim
18 words
A drive system as recited in claim 1 wherein said main driving engine is a gas turbine engine.
Claim 5
Dependent Claim
54 words
A drive system as recited in claim 1 further including a cooling means utilizing sea water as the cooling medium, operatively interconnected between said compressor and said gas turbine engine, said cooling means adapted to reduce the temperature of said compressed air produced by said compressor prior to entry into the gas turbine engine.
