Why jet engines are used at high altitudes?
For thrust. Engines are used to overcome the drag of the airplane.
Type of engine used to power space flights?
rocket engines,compared to jet engines
Are jet engines still used today?
yes they are, they are the engines you see on a 747 or even a small Private jet
Why aren't machines used anymore?
Um... they are.
What are steam engines being used for today?
trains x
Do they still make steam engines?
Yes, turbines used today are radial steam engines.
Thrust bearing used in most radial engines?
Yes it is. They use deep groove bearings in most radial engines. These types best for reducing friction while carrying both thrust and radial loads
Power for biplane?
2 wings, to determine which engine was used need to know what biplane
Why do all World War 2 carrier planes have radial engines?
They didn't. All American carrier planes had radial engines but some Japanese and British aircraft had liquid-cooled engines, also planes built in Germany for their carrier which was never finished had liquid-cooled engines. Radial engines were used in most cases because they were more rugged than other engines, a pilot would only need to watch his oil pressure gauge whereas using a different engine he would also have to check his coolant, and a single bullet in a liquid-cooled engine could cause it to seize up in a short time.
What are the disadvantages and advantages of a jet engine over radial engines or piston engines used for aircraft's?
The advantages, you move over a lot more land in a lot less time. The disadvantages, Jet engines use a lot more fuel, and are a lot louder.
What were planes powered by before jet engines?
Propeller driven piston internal combustion engines. Similar to the one in your car, except planes usually used either radial or rotary engines, both of which have the cylinders arranged in a circle and typically have a multiple of 9 cylinders.
What is a radial engine?
There were basically two types of aircraft engines, in-line and radial. In-line engines were like most car engines. You start with a solid block of metal and bore large holes in it for the pistons, one hole behind the other, all in a row. Normally these had to be water-cooled, adding an extra vulnerability to the airplane. A bullet through the radiator would soon cause all the coolant to leak out and soon the engine would seize up from overheating. Radial engines have the cylinders bolted on around the outside, like spokes on a wheel. They radiate from the middle, hence radial. Radial engines are roughly round, and wide when compared to an inline engine, but short, front to back. Because the cylinders are outside, all around the edge, not in the middle of a cylinder block, radial engines can be air-cooled. Think of the nose of a US P-47 - its blunt and wide because of its large radial engine housed there. The US P-51 had an in-line engine, and a pointy nose. The same with Germany's Bf 109 - pointy, inline, and the FW 190, blunt, wide, radial.
What parts are in the engine inWorld War 2 planes?
There were two types of airplane engines in WWII - radial, and in-line. Both had cylinders within which pistons traveled back and forth, powered by the exploding fuel. Radial engines were round, and very short front to back. The cylinders were bolted on all around the outside edge. These engines were air-cooled. Fighter planes with radial engines had a flat, blunt nose, like the US P-47 or the German FW 190. A radial engine could have a gun mounted to fire through the middle of the propeller hub. In-line engines were water cooled. That meant they needed a radiator just like a car.
What are 4 major search engines and a major directory?
Google is the most used, than Bing and Yahoo follow. All the other search engines are used by a very small percentage of world's population. Directories are not that popular anymore, since the invention of search engines.
How do you radial engine connected to turbo jet engine?
The fact that both are aircraft engines is the only connection.
How does the biplane create thrust?
Most biplanes had radial engines driving a propeller, this created thrust when it rotated.
What is the name of the artery in your wrist where you check your pulse?
The radial artery is the one that is used to take a pulse at the wrist.
