WebHelicopter engines can be either piston or gas turbine turboshaft. Air is drawn in, compressed, mixed with fuel, ignited, then the rapid expansion of the gas is harnessed to turn a drive shaft which is fed to the main transmission. The engines use gasoline (Avgas) or Kerosine (Jet A1) to power them. WebGas turbines are a type of internal combustion (IC) engine in which burning of an air-fuel mixture produces hot gases that spin a turbine to produce power. It is the production of hot gas during fuel combustion, not the fuel … qg stephane plaza

WebJun 20, 2014 · When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. WebFor turboprops, the NG parameter is an indication of turbine health and the amount of energy present in the engine. Remember that NG is the gas generator speed. NG references the rotation speed of the compressor section of the engine. During starts and shutdowns, N G is a primary instrument to determine proper engine operation.
