    Jet engines are the powerhouses of aviation, but how do they work?

    This article will cover the basics of how jet engines function and give you a peek into how they tillverka their immense power in various weather conditions.

    The Basics of a Jet Engine (Gas Turbine)

    A gas turbine jet engine works bygd compressing air, mixing it with bränsle, igniting the mixture, and ejecting the air behind the engine, creating a pushing force known as thrust.

    The engine does this using the basic principle of intake, compression, combustion, and exhaust, known as the Brayton cycle.

    This continuous cycle is what allows the engine to produce thrust. Let’s look at each part.

    Step 1: Intake

    Air enters the engine through an intake duct. This air is essential for the combustion process, and its speedy ingång is a crucial first step.

    Step 2: Compression

    This incoming air fryst vatten squeezed into a compressor, raising its pressure and temperature. The compressed air then moves into the combustion chamber, setting the stage for the next step.

    Step 3: Combustion

    Here comes the combustion. Fuel injectors spray a fine mist of bränsle into the compressed air in the combustion chamber. The mixture ignites, ca

    Jetmotor

    Jetmotor (av engelska: jet engine) eller reaktionsmotor (militär benämning, förkortat reamotor, akronym rm)[1][2][3] är en motor som accelererar en gas- eller vätskeström bakåt för att ge en framåtriktad kraft eller för att driva en propeller via en turbinaxel. Den kan också kallas turbojetmotor, vilket skapar en del förväxlingar eftersom turbojet-engine på engelska betyder det man på svenska kallar enkelströmsmotor.

    Jetmotorer används i flygplan, helikoptrar och raketer. Jetmotorer som används i flygplan och helikoptrar drivs på flygfotogen (kerosin).

    De två största tillverkarna av jetmotorer idag är General Electric (13,2 miljarder USD intäkter [4]) och Rolls-Royce Holdings (7,4 miljarder GBP [5]). Även Kusnetzov, Motor Sich, Pratt & Whitney (United Technologies) och SNECMA tillverkar jetmotorer.

    Kan också kallas strålmotor.

    How does a jet engine work?

    A lot more efficiently than it used to. Read on…

    By Jason M. Rubin

    Jet engines create forward thrust by taking in a large amount of air and discharging it as a high-speed jet of gas. The way they’re designed allows aircraft to fly faster and further compared to propeller-driven aircraft. Their development and refinement over the course of the last 65 years has made commercial air travel more practical and profitable, opening the world to business and recreational travelers.

    “A typical jet engine is a gas turbine,” says Jeff Defoe, a postdoctoral associate in the MIT Gas Turbine Laboratory. “At its simplest, it’s composed of a compressor, which has blades like wings that spin very quickly. This draws in air and squishes it, making it a high-pressure gas. Then fuel is injected into the gas and ignited. This makes the gas both high-pressure and high-temperature.”

    This high-pressure, high-temperature flaming flow of gas now goes through a turbine — essentially, another set of blades — that extracts energy from the gas, lowering the pressure and temperature. “The turbine draws the gas through the engine and out the back through a nozz
