How a jet engine works This simplified diagram shows you the process through which a jet engine converts the energy in fuel into kinetic energy that makes a plane soar through the air. (It uses a small part of the top photo on this page, taken by Ian Schoeneberg, courtesy of US Navy...
The theory is simple: Jet aircraft fly at high altitudes through air that is less dense and drag is reduced. The Musk team decided the air pressure inside the system should be one-sixth the pressure of the thin atmosphere on Mars, which significantly reduces drag on the speeding pods. In ...

their utilization was averted until the commercial drilling and creation of petroleum began in the mid-1850s. By the late nineteenth century, engineering advances prompted their widespread selection in a variety of applications. This highlights that learning was done and some focus was also on the ...

Not all engine-powered boats use propellers. Jet Skis® and jetfoils (large, hydrofoil versions of jetskis) use engines to power impellers (water pumps) that create a powerful backwater-pointing jet of water. The force of the water shooting back into the water powers the boat forward, muc...
