Turboprop VS Turbofans

Turboprop VS Turbofans

  • The ATR ( Avions De Transport Regional ) is Celebrating it's the 39th Anniversary. Of late, they have pioneered the Turboprop regional jet industry.
  • On this occasion, It's compelling to highlight the Beauty of these turboprops.
  • Turboprop propeller have a large diameter compared to Turbofans, it accelerates a large volume of air, the Bypass Ratio can be 50 to 100.
  • As it accelerates a large amount of air by a small degree, a low disc loading increases the aircraft's energy efficiency, very fuel-efficient.
  • Modern turboprops operate at nearly the same speed as small regional jet airliners but burn two-thirds of the fuel per passenger, very miser.
  • When Compared to turbofans, turboprops are optimum at flight speeds below 725 km/h and FL250 Altitude because the jet velocity of the propeller is relatively low.
  • Turboprops have lower landing speeds and hence can land on short runways. Some airplanes such as Twin Otters can land on runways which are less than 1,000ft in length.
  • Turboprops are suited to unpaved runways as well. Dust and FOD objects have a significantly less impact compared to turbojet engines.
  • Turboprops have lower acquisition & operating costs. Lifecycle operation costs of are lower as compared to turbojet aircraft (segments).
