It is a great privilege to be able to retain the services of a lear jet when you need it for business or personal use. Some individuals are seasoned travelers, while others might feel some pangs of reservation when they think of executive jet travel. It sometimes helps assuage any hint of anxiety by becoming informed about your jet, and one way to do that is to understand a bit about how jet engines operate. With knowledge comes understanding, and that understanding will make you more comfortable on your next flight.

The most commonly used contemporary executive jet engine is the turbofan engine. This type of engine is used in commercial airliners and also in military jets because they are both efficient and quiet in use. A turbojet engine is place behind a fan, and the engine powers the fan. Some of the airflow goes through the turbojet and is used to power the fan, but much of it bypasses the turbojet and provides the engine thrust.

Unlike military jets, a civilian-use Lear jet uses high bypass ratio turbofans with low specific thrust. This thrust is achieved by using a single stage fan. By improvements made to the turbine's cooling and material technology, the gas generator, or core, of the engine has become smaller and lighter, which makes for a reduced core flow. This has the advantage of increasing the bypass ratio which can give an aircraft a higher thrust while using less fuel. This technology was used to good effect in wide-body aircraft, making their use both cost-efficient and practical.

The blades that power the turbine in the turbofan engine have been improved over the years. Today they are made from mono-crystalline crystals and nickel-based superalloys. These superior materials have the advantage of being able to operate under the high temperatures that the turbofan engine generates with fewer complications from distortion of the blades. In addition, changes in blade cooling capabilities have made them able to handle the additional temperature from the engine. The compression system is allowed to leak out a precise amount of cool air, which is guided into the blade. The cool air picks up the excess heat from the blade, then transfers it to the main gas stream, where it is released. What all this means to the civilian traveler is that you will reach your destination both quickly and safely when you fly on turbofan engine jets.

Getting a small glimpse inside the workings of your executive jet can help you understand how it operates. This way you will have the facts, and instead of worrying, you will feel safe and secure the next time you fly, because you know factually that you are.
