COMO funciona um MOTOR A JATO? Por que NÃO DEU CERTO em AUTOMÓVEIS

Summary

The script narrates the origin and operation of jet engines, also called reaction engines, popular in aircraft. It first mentions early concepts and history of jet engines, highlighting Egidius Elling and Frank Whittle, then details how jet engines work in a simplified way. It discusses applications of jet engines in aerospace and cars, explaining why they didn't succeed in road vehicles. The text closes reflecting on advantages, costs and challenges of jet engines in transportation. It mentions some jet-powered motorcycles at the end, including the MTT Y2K superbike.

Takeaways

• 😃 The concept of jet propulsion dates back to the 1st century CE with Heron of Alexandria's aeolipile.
• 👨‍🔬 Norwegian engineer Ægidius Elling built the first functional gas turbine in 1903.
• ✈️ The first operational jet plane was the German Heinkel He 178 in 1939.
• 🔧 Frank Whittle and Hans von Ohain independently developed jet engines in the 1930s.
• ⚙️ Jet engines have a simple working principle - intake, compression, combustion, exhaust.
• 🚀 Key advantages are high power, high altitude performance, smooth operation.
• 🚘 Automakers experimented with jet engines in cars in the 1950s-60s but with limited success.

Q & A

Who was the first to patent a jet engine design?

The British inventor John Barber patented a jet engine design in 1791, although he was unable to build a working prototype before his death in 1793.

When was the first working jet engine built?

The first working jet engine was built by Norwegian engineer Ægidius Elling in 1903. It produced 11 horsepower.

What was the first jet-powered aircraft?

The Heinkel He 178 was the first jet-powered aircraft. It completed its first flight on August 27, 1939 in Germany, designed by Hans von Ohain.

When did jet engines first see use in combat aircraft?

Jet engines were first used in combat aircraft during World War II. The Messerschmitt Me 262 fighter plane entered service with jet engines in 1942 with the German Luftwaffe.

Who developed the first British jet engines?

Frank Whittle developed the first British jet engines, starting in the 1930s. Rolls-Royce later produced the Welland and Derwent jet engines based on Whittle's designs.

How do jet engines work?

Jet engines work by sucking in and compressing air, mixing it with fuel and igniting it. The hot expanding gases are forced out the back to produce thrust. The gases also spin the turbines to provide power.

What was the first jet-powered car?

The first jet-powered car was the Rover JET1, built in Britain in 1950. It used a small jet engine mounted in the rear and reached a top speed of 142 mph.

When did jet engines become widely used on commercial aircraft?

Jet engines started becoming widely used on commercial aircraft in the 1950s, with early jetliners like the de Havilland Comet and Boeing 707 entering service.

Why didn't jet engines become common for cars?

Jet engines were found unsuitable for cars due to high fuel consumption, lack of low-end torque, and high cost. Piston engines remained dominant for road vehicles.

What was the fastest production motorcycle using a jet engine?

The fastest jet-powered production motorcycle was the MTT Turbine Superbike Y2K, introduced in 2000. It used a Rolls-Royce turbine engine to reach 365 mph.
