CLASSIFICATION OF GAS TURBINES
Gas turbines may be classified as follows: 1 Constant Pressure Combustion Gas Turbine In this type, the fuel is burned at constant pressure and the cycle used is the Joule cycle. The turbine belongs to the reaction type using oil fuel and is fitted with an axial flow rotary air compressor which is coupled to…

INTRODUCTION
The gas turbine is the most satisfactory way of producing very large power in a self-contained and compact unit. The gas turbine obtains its power by utilising the energy of a jet or burnt gases and air, the velocity of the jet being absorbed as it flows over several rings of moving blades which are…

Example 15.1
An axial compressor is fitted with half-reaction blading, the blade inlet and outlet angles being 50° and 15° when measured from the axial direction. The mean diameter of a certain blade pair is 85 cm and the rotor runs at 5500 rpm. Calculate the necessary isentropic efficiency of the stage if the pressure ratio of…
