Do airlines still use prop planes?

Propeller planes, otherwise known as Turboprops, are still a widely used method of transport for traveling, whether it be a business flight or a quick getaway. I bet you thought those 1938 old planes would be long gone, after the invention and revolution of the jet plane – but they are still flying!

Why are jet engines better than propellers?

A: Jet engines are faster due to the way they generate thrust. They produce thrust by increasing the pressure inside the engine with a combustion reaction. The increased pressure in the engine exerts more force in the forward direction.

Are propeller planes more reliable?

Both turboprops and jets are powered by turbine engines, so they are essentially the same thing and thus, are considered to be equally as safe. Because of the drag propellers cause, they actually allow the aircraft to stop much more quickly than a jet.

Why turboprops are making a comeback?

3,400 regional jets (according to Flight Global’s Flight Fleets Analyzer), the regional jet market is being challenged by the turboprop. Regional airlines are increasingly recognising the benefits of investing in propeller aircraft, including: Versatility.

Are propeller planes bumpy?

If you compare flying in commercial turboprop airliners, to the jet airliners, you can notice that flying in propeller aircraft in general is more bumpy. But the reason has nothing to do with propellers, at least not directly. Propellers per se are not causing turbulence.

Why do propeller engines make less noise than turbo fan engines?

The cold air stream of a turbo fan engine is slower so there is less speed difference at the exhaust and less noise. The noise of propeller engines is mostly dependent on the speed of the propeller. The tips of the propeller blades are obviously the fastes moving parts.

Do propellers slow down the speed of a jet?

However, a propeller will force any aircraft to fly more slowly than jets. Their efficiency tanks once the propeller tips rotate at supersonic speed, so it is best to keep cruise Mach below 0.6. But commercial traffic wants to fly as fast as economically possible, and with turbofans this limit is only reached around Mach 0.85.

Why are jet planes more popular than turboprops?

Since most people are flying to go relatively long distances there are comparatively more jets in scheduled airline service than turboprops. Noise is probably also a factor: fast turboprops like the Bear are LOUD not due to the engine, but due to the propeller.

Why is a propeller more efficient than a turbine?

This formula shows that it is better to accelerate a big mass of air only a little than a smaller mass by a lot. Propellers do this and for that reason offer the best efficiency. Turboprops use less efficient, but lighter gas turbines for creating power, but retain the efficient propeller.
