Question

Advantage and dis disadvantage of turboprop engine

Answer 1

Advantages: • in dense air, i.e. lower levels, a propeller has a higher efficiency than jet exhaust; • generally turboprop aircraft can operate into shorter runways than jets; • the propeller can be feathered to minimize drag in the event of engine failure, which is not possible for jet or turbofan engines. • mechanical reliability due to relatively few moving parts; • light weight; • simplicity of operation; • high power per unit of weight;


Disadvantages: • propellers lose efficiency at high altitudes; • vibration levels can cause slight passenger discomfort; • en-route weather (icing/turbulence) can cause problems and additional passenger discomfort due to operating altitudes (often in clouds); • older generation turboprops are slow.

Answer 2

Advantages of turboprop engine:

• The propeller can be feathered to limit haul in case of motor disappointment, which isn't feasible for turbofan motors or jet.
• In thick air, at lower levels, propeller has a higher effectiveness than the jet stream fumes.
• For the most part turboprop airplane can work into shorter runways than planes.
• Mechanical unwavering quality because of non existence of many moving parts.
• Light weight and high force per unit of weight.

Disadvantages  of turboprop engine:  

• Propellers lose effectiveness at high elevations.
• Vibration levels can cause slight traveler discomfort.
• On the way climate turbulence can cause issues and extra traveler inconvenience because of working heights.
• Older age turboprops are moderate.
