CALCULATING AND REDUCING NOISE GENERATED BY MARINE GAS TURBINE PLANTS

RASCHET I SNIZHENIYE SHUMA SUDOVYKH GAZOTURBINNYKH USTANOVOK

The marine gas turbine propulsion plant consists of a number of components that are noise sources. The main ones among them are the compressor, combustion chamber, turbine, reduction gear, piping, and the suction and discharge ducts. The engine can be said to have four noise sources when regarded as a unit: gas turbine plant ( GTU ) casing, the suction and discharge ducts, and the reduction gear. GTU noises can be broken down into noises of aerodynamic and mechanical origin, of which the aerodynamic noises radiated by the suction and discharge ducts, the compressor housing, and the piping are of greater significance. So far as the engineroom is concerned, the principal noise source is the GTU casing and reduction gear because the suction and discharge ducts usually are beyond its confines and are fitted with silencers. The concept of the GTU casing, thus includes the compressor and turbine casing proper, the combustion chamber, the piping, the bedplate, and the heat exchanger for coolers, regenerators, and waste heat boilers. This paper considers the noise generated solely by axial flow GTU with combustion chambers.
