Components of jet engines. Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1.
NACA duct. Concept picture of a submerged inlet for a jet aircraft. A NACA duct, [ 1 ] also sometimes called a NACA scoop or NACA inlet, is a common form of low- drag air inlet design, originally developed by the U.S. National Advisory Committee for Aeronautics (NACA), the precursor to NASA, in 1945.

A JT9D turbofan jet engine installed on a Boeing 747 aircraft. Jet engines power jet aircraft, cruise missiles and unmanned aerial vehicles. In the form of rocket engines they power model rocketry, spaceflight, and military missiles. Jet engines have propelled high speed cars, particularly drag racers, with the all-time record held by a rocket car.
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight . [ 1 ] Most aircraft engines are either piston engines or gas turbines , although a few have been rocket powered and in recent years many small UAVs have used ...
Engines in nacelles on a Boeing 707. A nacelle (/ n ə ˈ s ɛ l / nə-SEL) is a streamlined container for aircraft parts such as engines, fuel or equipment. [1] When attached entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. [2]
Aircraft engine starting. Ground crew disconnecting an air start hose from a Boeing B-52 Stratofortress. Many variations of aircraft engine starting have been used since the Wright brothers made their first powered flight in 1903. The methods used have been designed for weight saving, simplicity of operation and reliability.
Hush kit for the Pratt and Whitney JT8D-1 through -17 engines. Two JT4As installed on a KLM DC-8. A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass ...
Pratt & Whitney R-1535 Twin Wasp Junior. The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of 985 in 3 (16 L); initial versions produced 300 hp (220 kW), while the most widely used ...
