Why do all jets look the same?

Almost all medium and large jetliners fit into the same pattern: two engines, straight-tube fuselage, and a conventional tail. Where has all the imagination gone? It’s not that aeronautical engineers have run out of ideas. Instead, the demands for efficiency have driven designs to this narrow range of similarity.

Why are there no tri Jets?

The rationale for this was that if one engine failed, there would be enough time to make an emergency landing at the nearest airport using the other remaining engine. Of course, long-distance routes over oceans were impossible for twin-jets under these rules – thus requiring aircraft with more than two engines.

How are planes designed?

Whether it’s a small single-engine husky or a massive Airbus A300-600ST , aircraft are designed in a three-stage process. This consists of the conceptual design phase, the preliminary design phase, and finally the detail design phase.

Who designs fighter jets?

Lockheed Martin’s aircraft leadership is earned through relentless research and development of high-performance combat, air mobility and reconnaissance and surveillance aircraft.

Do airplanes have 3 engines?

A trijet is a jet aircraft powered by three jet engines. In general, passenger airline trijets are considered to be second-generation jet airliners, due to their innovative engine locations, in addition to the advancement of turbofan technology.

Why does a DC-10 have 3 engines?

Older passenger jets were built with three or four engines because they needed the combined thrust when engine technology was not as advanced as it is today. These highly reliable high-thrust engines have reduced the need for additional engines.

Why do jet planes leave smoke trails?

Jets leave white trails, or contrails, in their wakes for the same reason you can sometimes see your breath. The hot, humid exhaust from jet engines mixes with the atmosphere, which at high altitude is of much lower vapor pressure and temperature than the exhaust gas.
