What are the main differences between the engines in jet fighters and the engines in jet airliners?

Military jets are pure turbojets, while airliners are fanjets. The fan produces lower-velocity air that acts as an insulator to the high-energy air produced by the core of the engine, thus dampening the noise.

Why can’t India build a jet engine?

India cannot ask ‘whole’ world to give this sophisticated technology because only a handful of nations could manage to develop modern fighter jet engines after decades of experience, trial, huge expense, infrastructure and ambition.

Which countries have fighter jet engine technology?

USA, Russia, France, China. All have fully domestic aeronautics industry. UK no longer develops aircraft or engines alone, now it’s jointly with other leading European partners (France, Germany, Italy, Spain).

How many countries have jet engine technology?

As far as I know, only 4 countries can build aircraft jet engines on their own: USA {GE, P&W} Russia {Klimov, NPO Saturn} France {Safran}

Why is it difficult to make jet engines?

Jet engines don’t have any clear avenues for innovative development, rather, you just have to work new materials and geometries into your engine which makes R&D very expensive and competitive. It goes without saying that designing an engine from scratch is a very expensive and intense process.

Which country made the jet engine?

Germany
This event is customarily regarded as the invention of the jet engine, but the first operational jet engine was designed in Germany by Hans Pabst von Ohain and powered the first jet-aircraft flight on August 27, 1939.

Which country can make airplane?

List of countries by aircraft and spacecraft exports

#	Country	Country’s main aircraft and spacecraft manufacturers
1	United States	Boeing, Lockheed Martin, Sikorsky Aircraft, Gulfstream Aerospace
2	France	Airbus, Dassault Aviation, ATR, Arianespace
3	Germany	Airbus
4	Canada	Bombardier

Why is a turbofan more efficient?

Because the fuel flow rate for the core is changed only a small amount by the addition of the fan, a turbofan generates more thrust for nearly the same amount of fuel used by the core. This means that a turbofan is very fuel efficient. In fact, high bypass ratio turbofans are nearly as fuel efficient as turboprops.

What are some examples of outsourcing in the aviation industry?

For example, the U.S. commercial aircraft industry has had a practice of outsourcing since the early 60’s better known as “offset programs,” whereby foreign manufacturers produced key components in exchange for completed aircraft purchases.

Do companies that outsource to foreign countries hire less skilled workers?

Companies that outsource to foreign countries tend to hire less skilled workers whenever the work does not require a high skill level to manufacture products. This results in Americans holding higher skill level jobs.

Is outsourcing good or bad for the economy?

Outsourcing is controversial and often politically manipulated to make claims about job losses in the United States with little to no discussion on job creation from outsourcing by U.S. companies. However, outsourcing by U.S. companies provides benefits to foreign economies and to the U.S. economy.

What are the most commonly outsourced IT functions?

The most commonly outsourced IT functions are: Web development. Hosting. Software and application development. Website/application maintenance or management. Technical support.
