Pratt AND Whitney 4052 Boeing 767 Essay Samples
General information about the engine
The Pratt and Whitney 4052 is a family of high-bypass turbofan aircraft engines that produces a thrust ranging from 52,000 to 99,040 lbf that is approximately 230 to 441 kN. The engine was built by the successor to the JT9D series engines. The engine has found much wider application than its predecessor due to its efficiency.
The engine is designed for three families based on the diameter of the fan. The first family is the family of 94 inch (2.4M) in diameter fan that has a thrust ranging from 52,000 to 62,000 lbf approximately 230 to 275 kN (Liu 45). The engine powers the Airbus A310-600 aircraft, Boeing 747,767 and even McDonnell Douglas MD-11 aircraft.
The second family of the engine is the 100 inch (2.5 m) diameter fan engine that was developed specifically for the Airbus Industries A330 twinjet. The thrust of this category of the family ranges from 64,500 to 68,600 lbf approximately 287 to 305 kN. The engines in this category have reduced maintenance by approximately 15%.
The third family of the engines is the 112 inch (2.8) diameter fan which was developed specifically for the Boeing’s 777. The thrust of the engine is 86,760 to 99,040 lbf that is approximately 386 to 441 kN. The engine entered service in June 1995 used by the United Airlines. It is recorded that the engine entered service with 180th minute ETOPS certification (Liu 76). The Pratt and Whitney engine are widely used as they are efficient and consumes less fuel as compared to other engines. The thrust that they produce can propel high bypass Aircrafts. Fuel Economy
The Pratt and Whitney 4052 which is used by Boeing 767 is a type of engine that is economical. The engine minimizes the use of fuel since it burns all the fuel. The burned fuel has the ability to produce the thrust that can propel the aircraft (Connors 111). Most of the aircraft industries prefer the Pratt and Whitney 4052 engine since it produces high thrust with the use of less fuel. The engine can be used to propel the aircraft to a long distance with the economical fuel use.
The Pratt and Witney engine can produce a thrust of approximately 52,000 to 99,040 lbf. The thrust is able to propel the aircraft at a higher speed. The thrust is considered ideal for aircrafts that require high energy and go for longer distances. The engine is preferred in the military aircrafts as the thrust can propel the military aircrafts with the required speed.
The engine produces high bypass energies, and most of the pilots were not trained previously on the use of this type of the engine. The training also could not take place since the engine was developed recently. The previously trained pilots on other engines can also use the engine, but they need some recap of the basic skills. The U.S has of late trained its pilots on this engine since the engine is mostly preferred by the military.
Maximum flight distance
The engine has ability to propel the aircraft to higher distance because of the thrust that is generated by the engine. Historically, the speed generated by the engine can make the aircraft to move fast. The speed generated by the engine has made it to be adopted in the military aircrafts. The engine travels a distance of 43,009.789 kilometers within an hour (Bhangu 22).
Engine Time on Wing
The engine is efficient in fuel utilization. The Pratt and Whitney engine is manufactured in such a way that it can regulate the energy produced. The fans fitted on the wings control the energy produced by the engine (Connors 123). The control of the energy makes the engine stay long in the wings without being exhausted. It is recorded that the engine can stay for up to a maximum of eighteen hours on the wing.
