All engines have to be certified and tested to demonstrate certain thresholds of what can be ingested. So, yes.
Almost all of the first aircraft engines were air cooled as this made for a lighter engine.
Engines power the aircraft forward so the wings gain lift to raise the aircraft into the air.

In aircraft aerodynamics, drag is the force that opposes forward motion, caused by air resistance as the aircraft is pushed forward by it's engines.
In 2010, a volcanic eruption in Iceland brought much of Eoropean air travel to a halt. The increased levels of ash were bad for visibility nad plane engines.
That is condensation from hot engines in cold air.
Yes, it does. The planes engines must provide enough forward thrust so that the air passing over the wings generate enough lift for the aircraft to fly.
Yes, they built aircraft engines for the German Air Force (Luftwaffe).
Gliders and hot air balloons have no engines. (also paper darts, if you count them!)Gliders
Spacecraft lack wings & their engines don't require air to function.
The higher an aircraft goes the less dense the air is. What this means is there is less air particles surrounding the plane. This has a positive and negative effect on the aircraft. The positive effect is there is less friction on the aircraft allowing for better fuel economy and speeds. The negative effect is that air flow is needed to create lift. If not enough air flows over the wing then not enough lift is produced to keep the aircraft at that height. They counteract this for high altitude aircraft by increasing the speed of the aircraft. It also has an effect on the engines performance. If you get high enough the air becomes so thin that there isn't enough air to support the operations of the engines. this is why there is a mixture lever on many aircraft to allow you to change the fuel/air ration depending on height/
Air boats are powered by either an aircraft or automotive engines that's why it differs from the other boats.
