May 11, 2023 · The Beginner's Guide to Aeronautics has been on the web for over a dozen years. During that time, NASA projects have come and gone and the intended audience has variously changed from high school students to college students and back to middle school students. So there is a wide breadth of information here at the site.

Photo: Early Turbojet engines on a Boeing B-52A Stratofortress plane, pictured in 1954.The B-52A had eight Pratt and Whitney J-57 turbojets, each of which could produce about 10,000 pounds of thrust.Picture courtesy of US Air Force. Whittle's original design was called a turbojet and it's still widely used inairplanes today. A turbojet is the simpl...
Photo: The gray tube you can see under the rotor of this US military Seahawk helicopter is one of its twin turboshaft engines. There's another one exactly the same on the other side. Photo by Trevor Kohlrus courtesy of US Navy. You might not think helicopters are driven by jet engines—theyhave those huge rotors on top doing all the work—but you'd b...
Photo: A turboprop engine uses a jet engine to power a propeller. Photo by Eduardo Zaragoza courtesy of US Navy. A modern plane with a propeller typically uses a turboprop engine.It's similar to the turboshaft in a helicopter but, instead ofpowering an overhead rotor, the turbine inside it spins a propellermounted on the front that pushes the plane...
Photo: A turbofan engine produces more thrust using an inner fan and an outer bypass (the smaller ring you can see between the inner fan and the outer case). Each one of these engines produces 43,000 pounds of thrust (almost 4.5 times more than the Stratofortress engines up above)! Photo by Lance Cheung courtesy of US Air Force. Giant passenger jet...
Photo: A Pegasus ramjet/scramjet engine developed for space planes in 1999.Photo by courtesy of NASA Armstrong Flight Research Center. Jet engines scoop air in at speed so, in theory, if you designedthe inlet as a rapidly tapering nozzle, you could make it compressthe incoming air automatically, without either acompressor or a turbine to power it. ...
Feb 14, 2012 · 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 ...
Jan 30, 2022 · How airfoil wings generate lift#1: An airfoil splits apart the incoming air, lowers the pressure of the upper air stream, and accelerates both air streams downward. As the air accelerates downward, the wing (and the plane) move upward. The more an airfoil diverts the path of the oncoming air, the more lift it generates.
May 13, 2021 · The first airplane to successfully use a gas turbine engine was the German Heinkel He 178, in August, 1939. It was the world's first turbojet powered flight. General Electric built the first American jet engine for the US Army Air Force jet plane . It was the XP-59A experimental aircraft that first flew in October, 1942.
Jul 17, 2023 · A gas turbine jet engine works by compressing air, mixing it with fuel, 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 ...
