What Is Turboprop Engines?

Improved Essays
3:1 TurboProp Engines:
A turboprop is a variation of a Jet Engine which has been optimised to drive a propeller instead of a Fan blade. Aircraft’s that are fitted with a TurboProp engine are very efficient at lower airspeeds, Burn less fuel per Nautical Mile an requirer shorter distances for take off and landings. Common among many small charter airlines and freight companies is the use of turboprop engines rather than turbine or turbofan engines mainly due to the reduced costs associated with running the engines. The reduction in costs and greater ability to maintain turboprop engines, allows small airlines to offset the reduction in cruising speed and performance making them the most appropriate choice for operations.

His idea was driven by the need for Britain to gain air superiority against the rising Luftwaffe but also as a way to to mark their presence as a force in Europe.
The jet engine overtime become more appealing and more commonly used for military aviation. Jet engines were able to provide the best performance in terms of speed and altitude but also enabled nations to gain air superiority in regions. Jet powered aircrafts were able to out speed and manoeuvre any other aircraft which the military found appealing to gain superiority. However jet engines were also trialled in civilian aviation through the Concorde which as in use from 1969 until it was decommissioned by all airlines in 2003. The idea behind the Concorde was to cut transatlantic flight times in half as the aircraft was able to reach a staggering Mach 2.04 or 2,179 KP/H ( Technical specs, 2016) however after a number of crashes they were decommissioned due to

Aircrafts that are fitted with Jet engines are typically used for high altitude, long distance travel as their performance peaks in conditions unsuitable for any other engine variant. As aircraft climb to higher altitudes the density of the air reduces making propeller driven engines less desirable as their performance drops. Their is a reduction in the amount of air around which means propellers at higher altitudes begin to spin through nothing, not able to produce airflow over the aerofoil. This means that aircrafts climbing to higher altitudes require alternate engines to create the thrust needed to maintain

    Generally, lost cost operators are smaller airlines that offer cheaper fares but reduced luxuries. Low cost airlines have also been affecting and revolutionizing the performance of the airline industry with low fares that appeal to consumers. For example, Southwest is a relatively new airline that is gaining in popularity amongst consumers (Gowrisankaran, 2002). Unlike most airlines, Southwest is different from their competitors because they do not use a ‘hub and spoke system’ (Gowrisankaran, 2002). This system refers to, “a system of airline routes that allows for efficient use of airplanes to cross into other airports to distribute passengers along international flights” (TOH, 1985).…

    The one time it seems that the buyers were powerful is after 9/11 because everyone was afraid to fly and they started to ride buses, trains or drive their own car. JetBlue was smart to operate from JFK, knowing that JFK mainly operated internationally. They found less competition for domestic flights at JFK and JetBlue capitalized on it. Where there was high demand for flights, JetBlue focused on that demand and was able to sell fares at low prices. They had already hedged some cheap fuel which their competitor did not.…

    In fuel cost, I decided to use the aircraft that is low fuel capacity. In staffing, I decided to pay them union requested salaries and only employed the union suggested number of staff. In maintenance, I decided to apply less A check as possible. In airport service charge, I decided to fly to the airports that have fewer passengers handling charges and parking fee. Our airline can stay competitive in the current market by fly to the airports that exclusive by our airline.…

    Even if not recognized as a possible weapon at the beginning, on September 3 1914 French air patrol used airplane for observation of general Kluck’s army northeast of Paris. Information obtained from the air helped French forces to make Germans to withdraw thus proving airplane usefulness for military purposes.4 To the military this new technology, as a product of a new aeronautical science, opened up a new dimension of the air and received a powerful impetus to military and airpower development.5 Even the most conservative military experts saw its potential as a valuable mean for observation and reconnaissance. Moreover, usefulness of an airplane proved to be so valuable that the French military requested development of purpose-build…

    Some aircrafts like airliners or cargo planes use high bypass fans or turboprops as they require higher fuel efficiency which is achieved by accelerating large mass of gas by a small amount. On the other hand the fighter jets require very high thrust and not high fuel efficiency so the employ afterburners on a low turbofan bypass core. Working principle The basic working of aircraft propulsion system is based on Newton’s third law according to which ‘every action have equal and opposite…

    First it exhibits economics scope. By using the hub and spoke system the network airlines have been able to serve some 38000 city pairs. • The budget airlines also favor flying point to point rather than through hubs. They also choose to fly out of secondary airports which cheaper than the more dominating hubs. This is a lot cheaper.…

    There is potential of market leadership in reaching to less visited destinations, developing countries and established economies. 4.4 Minimizing Overhead Expenses LCC should aim to lower overhead costs such as office expenses and personnel cost as it is difficult to impose high airfares on passengers. By fully maximising resources and removing unnecessary costs, it is able to align with its ‘no-frills’ business model while sustaining profits. 4.5 Domestic leadership in Asia Pacific Region Since LCC are limited in their flying ranges, flight frequency for short haul routes should be increased to remove any chance of leaving aircrafts idle. Perishability is a great enemy and LCCs should strive to cater to more passengers in competent availability.…

    The wing length of helicopter 3 is larger than its base length, implicating that the surface area of the rotor is significant to the apparent size reduction of a smaller base length (Diagram 8.3). It is evident in Graph 15.1 that the larger rotor length and smaller base length is more successful than a smaller wing length and larger base length. According to Barsalou from Minitab (2016), the optimal design for a paper helicopter includes that of a smaller base length and larger rotor length. The larger wing/rotor span is theoretically supposed to apply more upward lift, thus increasing the paper helicopters flight…

    I don’t see this changing. They are used to that plane so they are the most efficient with it. The downside is that fuel prices are going to rise and using the same plane means the fuel efficiency stays the same. The Bags Fly Free motto is great and should be kept. It has helped differentiate them from other carriers.…

    Fighter aircraft such as the Supermarine Spitfire and Hawker Hurricane that was used by Royal Air Force for the Battle of Britain, still today hold its legacy in the 21st century which shows the technological advancement for aircraft technology development was well ahead of its time. Development for the Spitfire and Hurricane came about because the Royal Air Force needed a fighter aircraft capable of competing again the German fighter aircraft Messerschmitt BF190 in the Battle of Britain. (Aviation History, 2006) It shows that warfare had created a rapid motivation for aircraft manufactures to develop aircraft that were better than its enemies for air…
