What Are the Differences Between Turboprops and Private Jets?
Though turboprops may look dated in comparison to modern private jets, they have remained a strong competitor in the aviation market. Additionally, despite using the same inner system which harnesses combustive power, these two engine types vary by their capabilities and applications. In this article, we will discuss the major differences between turboprops and private jets, alongside exploring some notable advantages which have elevated turbojets for use among private aviation enthusiasts in recent years.
A jet engine is a type of propulsion system that relies on the combustion of an air and jet fuel mixture to generate thrust. The engine accomplishes this through the use of a turbine which is turned either by a piston and crankshaft or simply the force of the exhaust gas pushing through its blades. When the jet fuel and air are burned together, they produce exhaust gas directly into a tight space so that it is highly pressurized, storing heaps of potential energy.
Whereas jet engines have their turbines mostly hidden from view, turboprops are characterized by their prominent propellers which can be seen in front of the engine. The propeller in a turboprop is similarly actuated by way of combustion power, as a result of burning a fuel-air mixture. However, whereas a jet engine may be propelled by exhaust gasses forcefully pushing through the turbine, turboprop engines can only work with a piston and crankshaft that spin the propellers blades.
While both turboprops and jet engines work on a similar set of principles, they have different benefits and disadvantages. With the combination of a turbine jet engine and a constant speed propeller, turboprops were a significant development in the 1940s that provided an efficient option for modern aircraft. However, the addition of a propeller ultimately limits how fast the plane can fly. Nevertheless, turboprops are often used for small planes and shorter flights where the benefits can outweigh the decrease in speed.
Firstly, turboprops have the ability to achieve liftoff with more weight on board than a private jet, allowing them to carry more people and luggage than on an equally sized jet. As such, turboprops have a clear advantage for small airports that cannot support operations for a mid-size jet. Another key benefit is that, because the turboprop is affixed to the front of the plane, turboprop aircraft can take off and land on very short runways, grass, gravel, or uneven strips. Conversely, jet aircraft usually require a long, flat runway to take off, along with a much longer space to land. Finally, the lower altitudes which turboprops fly make for excursions that are generally more comfortable with less turbulence than typically experienced on jet aircraft at high cruising altitudes.
Despite these factors, jet engines have several advantages of their own which have made them the most common option for commercial airliners. The first of these benefits is that jet engines are often more powerful and can fly further without refueling. Turboprops are less capable in these areas, operating only 2 hours on average with the ability to fly roughly 2,500 km without refueling, in contrast with a jet engine’s 7,000 km. Jet planes can also fly slightly faster and cruise at altitudes between 25,000 and 40,000 feet, whereas turboprops cruise between 15,000 and 25,000 feet. For these reasons, jet engines tend to be a better choice for longer distance flights, as well as for carrying more weight overall.
In general, jet engines excel at longer flights, whereas turboprops shine in shorter flights and those that involve irregular landing surfaces. As such, many private aviators have been choosing turboprop engines in recent years for their ease of operation. Nevertheless, private jets remain a dependable choice in certain heavy-duty operations.
