There is no actual answer, because a jet is called a jet because it has at least one jet engine.
Well yes, assuming if an airplane does not have a jet engine, it would not be called a jet.
Aircraft that can break the sound barrier, yes they are jets. Aircraft are jets if they are powered by jet engines, as opposed to piston engines which have propellers.
Yes, jets are planes but jets are mostly known as supersonic planes.
If you are asking about carburetor jets, then they are made from brass. Jet engines, are made with many different materials, the main one probably is titanium.
Jet Engine is used in jets.
The Global Hawk has a jet engine. Most of them have piston engines.
For the most part, jet engine aircraft mostly have 2 jet engines such as the a319, 737 and private jets such as lears and gulfstreams. However, this is purely dependent on the type of aircraft it is. Some aircraft, such as the 747, a340 and a380 have 4 jet engines.
The jet engines used jet fuel, not gasoline as the 6 main engines did.
Most civil aircraft have their jets either under-wing or in the tail or on the side of the tail. Most cargo aircraft and bombers have the same configuration. The B-2 has engines buried in the wing. Most fighters used to either have the jet embedded in the body or on the side.
Aviation fuel, similar to kerosene. Only smaller aircraft with piston engines use a fuel similar to gasoline, called AVGas (Aviation gasoline) Military Jets use fuels specially designed for Jet Propulsion, these formula are known by JP-#, Commercial Jets use Jet-A.
None. Jet engines don't have cylinders. While Jet engines don't have cylinders they have combustors (which can also be called combustion chambers). Due to turbulence and other problems early jet engines had multiple small combustors, most modern jet engines have only one large combustor as it is simpler to build. some jets have combustion 'cans' which are cylinders but have no moving parts within
they are now the heart of supar sonic jets we are seeing today . jet engines are used in planes, boats, ships etc. and provide more power than before.
