3. A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine , and a combustion chamber in-between. - WHAT IS GAS TURBINES ?..

4. - WHAT IS GAS TURBINES ?.. - LM2500 gas turbine provides propulsion power for response to a high speed operational requirements - Model : General Electric LM2500 GT - Location : GTMR STAND FOR : Gas Turbines Machinery Room - Starting System (APU) : Provides air for starting the LM2500 GT Fuel : Marine Diesel (MIL-F18884 or JP5-MIL-T-5224) - Performance : 23,000 BHP at 3,500 turbine RPM at 100°F inlet temp

5. - Brayton Cycle .. - PRINCIPLES OF WORK .. Gas turbines are described thermodynamically by the Brayton cycle . - In this cycle: 1. Air is compressed isentropically 2. Combustion occurs at constant pressure 3. Heated air expands through the turbine 4. Heat is rejected into the atmosphere.

6. - TYPE OF GAS TURBINES . - Turbojet .. Advantages of turbojet engine; Relatively simple design Capable of very high speeds Takes up little space Disadvantages of turbojet engine; High fuel consumption Loud limited in range and endurance A turbojet engine was first developed in Germany and England prior to World War II and is the simplest of all jet engines These engines are limited on range and endurance today are mostly used in military aviation.

7. - TYPE OF GAS TURBINES . - Turbojet .. The turbojet engine consists of four sections : 1. compressor 2. combustion chamber 3. turbine section 4. exhaust
