COMPRESSORS, GAS TURBINES AND JET ENGINES

Gas turbines have high standby losses and require lot of maintenance

Gas turbines has flat efficiency at part loads

Gas turbine is capable of rapid start up and loading

Gas turbine requires lot of cooling water

Gas turbines use both air and liquid cooling

Gas turbine's blade will appear as impulse section at the hub and as a reaction section at tip

Gas turbines have their blades similar to steam turbine

Large gas turbines use radial inflow turbines

Low weight and small frontal area

Small frontal area and high h.p.

High h.p. and low weight

High speed and high h.p.

Closed/open depending on other considerations

Open cycle

Closed cycle & Open cycle

Closed cycle

For operating pneumatic drills

In gas turbine plants

In starting and supercharging of I.C. engines
