The future of turboprop aircraft and who competes with them on short routes

59

Turboprop aircraft are still very widely used today. aviation... But what awaits them in the future and what are their prospects? Many industry representatives think and argue about this issue.


Pros of turboprop aircraft


In the world of civil aviation, turboprop aircraft retain their positions, first of all, where it is required not so much speed (this is for turbojet aircraft), but reliability and efficiency. In addition, the valuable ability of such aircraft is the ability to take off from almost any airfield, which makes them indispensable in the province, in hard-to-reach areas. For example, the An-12 and An-22 aircraft were actively used both in civilian transportation and in military transport aviation.

In addition, and more importantly, the turboprop engine remains very economical compared to more modern types of turbojet engines, including their military applications. It consumes significantly less fuel, which is a big plus, especially for small airlines serving local destinations. True, in the military sphere today it is difficult to call it the most important priority.

It is with the features of turboprop engines that the long service life of such aircraft is associated. They still often prove to be more efficient in certain destinations, and this leaves airlines and government agencies not to discount them. But time in any case does its job. Airplanes are aging, and the question arises, is it worth expecting that the production of aircraft with turboprop engines will continue in the future, or is their age coming to an end anyway?

Most likely, aviation will not abandon more economical and environmentally friendly engines in the future. Where high speed, range and high altitude are not needed, turboprop aircraft will remain in demand. For example, for flights at medium and short distances, which is especially important for regional and business aviation. They will also serve in the military sphere - at least until the resource is depleted by existing modifications.

The Beechcraft King Air can seat seven to eleven people, and many of these planes have luxurious interiors in which high-ranking or wealthy passengers feel comfortable. Piper Seneca planes fly around the world, often used as air taxis, allowing you to get to places where there are no airstrips for liners. The flight range of such an air vehicle is up to 1533 km, the speed is 365 km / h.



Turbojet aircraft take short distances


However, turboprop aircraft, despite their cost effectiveness, will find it difficult to compete with the more modern narrow-body turbojets that are increasingly used on regional routes. Representatives of the Brazilian company Embraer call such planes "crossovers" from the "light hand".

Until recently, it was believed that turboprop aircraft were clearly preferable to turbojets on short routes. But now the situation has changed: turbojet engines are also becoming more economical, their noise is decreasing, and narrow-body turbojet aircraft are gradually mastering regional directions.

Large world-class airlines are also interested in the possibilities of using turbojet aircraft on small routes. Thus, the Airbus concern plans to develop a hybrid passenger aircraft that could carry up to 100 passengers. Considering that it is planned to use electric motors in hybrid aircraft, they will be much more economical and environmentally friendly than other modern aircraft.

The latter point is also important, given that the requirements for the environmental friendliness of aircraft engines are growing all over the world, especially in European countries. Under pressure from the environmental community and governments, airlines are forced to accelerate the development of more environmentally friendly engines.

    Funny article. Nowadays, quite a few turbofan engines have a gear drive for the fan, which already brings them closer to the HPT. And in the near future, all the same, TVVD looms, which will finally erase the line between a turbojet engine of a large bypass and a theater of operations.

    An-12, practically, was not used as a passenger. An10 belonged to civilians. He had a lot to do with military transport, but still was a separate model.

      Unfortunately, it was built using a different technology than its transport brother, and this aircraft successfully fought for the not very honorable title of "the most emergency aircraft of Aeroflot", therefore it was quickly removed from the lines and sent to the scrap

        "Ukraine" is a proper name for the first side, not a modification or a type. As well as the first Il-18 was called "Moscow", for example. And ANT-37 with a female crew - "Rodina".
        Unfortunately, it was built using a different technology than its transport brother

        Absolutely the same and from the same materials. What is the reason ...
        the title of "the most emergency aircraft of Aeroflot"

        Fatigue cracks in the central submersibles are associated with more intensive operation of the civilian An-10 in comparison with the VTA-shny An-12 - both in terms of plaque and in cycles. The An-12 began to develop the same cracks, but did not manage to reach a critical state. And according to the results of the disasters of the An-10s, the An-12s were finalized: overlays, bulletins for inspections, and so on.

    Lufthansa (a German airline) is reducing its air fleet. In addition, all the A380 giant aircraft remain on the ground, they are planned to be returned to the manufacturer's plant, if they are taken of course.
    The reason is a virus, due to which there is less passenger traffic, high fuel consumption.
    Against this background, the demand for small (at least smaller) aircraft may rise.

      Hybrid aircraft engines?
      Carrying a huge, heavy battery?

      Not "engines", but "power plant". It is stated that on takeoff, gas turbine engines will create thrust with a jet, and rotate the generators, from which electric impellers will be powered. And in cruise mode, the power generators will be turned off and the gas generator will simply create a jet for jet thrust. At the same time, he will, indeed, consume less fuel. A rough analogy to the concept is the experience of the P-3 Orions, which on patrol switched off and feathered two engines out of four, which extended the patrol time almost twice. Ours on the Il-38 also experimented in this way, but this is how they introduced it into everyday practice.

      The hybrid does not need large batteries - they are only needed during take-off to rotate the electric motors (or even in some cases supercapacitors will suffice).
      The rest of the time, normal engines work in cruise mode.
      At the moment, such a scheme is optimal - efficiency is greatly improved,
      while maintaining or even improving takeoff performance.
      And with some tricks and landing.

    Colleagues, turboprop aircraft are and will continue to be produced! It is obvious. Well, piston too.

    The private aviation segment in the world is very large. And it only grows.
    In the post-Soviet space, it is small due to the specifics of the form of ownership of aircraft during the Soviet era. I mean that the developed network of airfields and infrastructure, the aircraft themselves, quickly fell into disrepair after the termination of their centralized maintenance and funding. And lack of demand.

    Besides, in aviation there is no concept of "old" aircraft, but there is the concept of "airworthiness". It is determined by the flight time, maintenance and condition of the aircraft. Airworthiness is extended, major overhauls are underway.
    They speak eloquently about this, for example, Tu-95 and B-52 in their modifications.

    For example, many planes from the Second World War still fly around the world. And this is over 75 years.
    And the newer aircraft of the 60s-90s are the backbone of the private jet fleet in the United States. This market is fundamentally different from the automobile market, including for reasons of much more responsible operation.
    This market is extremely conservative, with major aircraft improvements being registered and licensed.

    In this case, the credibility of the aircraft / helicopter model is determined by its flying time. And the same for engines.
    That is, I would like to give an example: the Austro Engine AE300 168 hp (diesel turbocharged aircraft engine) has flown 2,5 million hours on 2300 units since 2008.
    And the manufacturer is proud of it!
    Nobody refuses him ...
    And the same is the case with the models from Rotax and Lycoming ...

                Well then fine. :)
                Just do not confuse BJ ("business jet") and just "jet" (any jet plane; this is considered Americanism, but is ubiquitous).

    The author is generally far from understanding the issue.
    Currently, regional passenger turboprop aircraft, that is, aircraft with a capacity of 30-100 passengers, used for hub-and-spoke transportation, are produced by two companies - the French-Italian company Avions de Transport Régional (ATR) and the Canadian manufacturer Bombardier.
    ATR produces two turboprop aircraft, the 50-seat ATR 42 and the larger 70-seat ATR 72.
    The Canadians are producing the Bombardier Q400.
    According to the forecast of Flight Ascend Consultancy, the delivery of approximately 2035 regional passenger aircraft is expected by 7000, of which approximately 3000 are turboprop, while ATR will be represented in this market 350-400 units, Bombardier - approximately 100.
    The Chinese are not yet counted, but they cannot be discounted.

    In case of wartime, the passenger An-10 was easily converted into a transport docking with a different tail. With a ramp.

    Controversial idea. In peacetime, they did this trick once and calmed down.

    It seems to me that diesel engines should not be discounted.

    "Turboprop aircraft are still very widely used in modern aviation."

    For drug trafficking, this is the best plane. The prospects are bright.

      At large volumes and with turbojet engines, small jets are used (near Brazil). do not seem to complain ..

    Well, why on earth is Beechcraft to the topic?
    ATR-72 would be more appropriate.
