yes they are, they are the engines you see on a 747 or even a small Private jet
Jet Pack
The Germans invented the first operational jet engine during WW2.
No. Jet engines draw oxygen from the atmosphere to mix and burn with jet fuel, and cannot function in a vacuum. Rockets carry their own oxygen, and can travel in the vacuum of space.
Jet fuel is injected into high pressure air in jet engines.
They didn't invent radar, TV, angled flight decks, jet engines, bagpipes or haggis.
The jet engines used jet fuel, not gasoline as the 6 main engines did.
The jet aircraft was invented by the Germans during ww2. it was not perfected until after the war was over. Also the jet pack was in stages but never finished, not even to this day
In the 1940s the Nazi German aviation engineers developed the first working Jet engines and planes. There were a few that flew in combat. Many of the jets they produced sat and were never used because the war ended. The US, Brits and Russians grabbed the technology and the planes. They also were able to get the engineers too. However, the jet engine was patented by a British engineer long before the Germans developed the jet engine. See related question below. Edit; Sir Frank Whittle was the first to realise that the power of an engine was primarily based on how much oxygen it could ingest. This led him to invent the jet engine and the Germans, having read of his design pre-war, lost no time turning it to their advantage.
An aircraft propelled by jet engines rather than piston engines.
Many factories in Britain make jet engines.
jet engines require air, compression, and combustion to make it work
A jet plane is any aircraft powered by jet engines.

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
It is the height, width and length of a jet engine.
They didn't.
