Due to industrialization and huge household usage of electricity there is energy crises world wide. There is reduction of natural sources oil, water reservoirs, to make cheaper energy aerodynamic based Gas Turbines in combine & open cycle power plant are commonly used for electricity. Hydro power generation is also very cheep and dual benefit source of power generation. The aim of this forum is to share experience and awareness about modern techniques and up coming events in energy sector.

AERODERIVATIVES AND JET ENGINES
Aeroderivatives and Jet Engines:
Airbreathing jet engines are gas turbines optimized to produce thrust from the exhaust gases, or from ducted fans connected to the gas turbines. Jet engines that produce thrust primarily from the direct impulse of exhaust gases are often called turbojets, whereas those that generate most of their thrust from the action of a ducted fan are often called turbofans or (rarely) fan-jets.
Gas turbines are also used in many liquid propellant rockets, the gas turbines are used to power a turbopump to permit the use of lightweight, low pressure tanks to be used, which saves considerable dry mass.
Aeroderivatives are also used in electical power generation due to their ability to startup, shut down, and handle load changes quicker than industrial machines. They are also used in the marine industry to reduce weight. The GE LM2500 and LM6000 are two common models of this type of machine.
