The uses of lubricants and fuel in aircrafts?

Question

i want to know the uses or purpose of fuel and lubricants on aircrafts

Answer 1

You serious?

My suggestion is for you to start easy and then work it out.

Look up the meanings in a dictionary,then think about it.

Answer 2

Well to answer the first part of that question, the fuel is used as, in laymans terms, a feedstock for the engine - it makes the engine run which in turn produces the thrust to propell the aircraft into the air. However, you can't just go about putting your regular gasoline that you'd put into your car into an aircraft - although they used to when the aviation world first began!

Ok, so for propellor aircraft they use a specialised gasoline called Avgas. The most common is 100LL - 100 identifying the octane rating and LL meaning Low Lead. There are variations but most are not used in this day and age due to changing econmoy and environment, for example Avgas 130 which was used during WW2 for higher performance.

For Jet aircraft they use a fuel called...you guessed it - jet fuel! nice and simple! The most common of these areJet A-1 and Jet A, each have different characteristics and properties. Note that these are only used for civilian aircraft, not military. The miltary tend to put there own additives into their fuels due to the performance they require. There is also a fuel known as Jet B, this is a fuel which is used for Jet aircraft operating in cold environments i.e the fuel will not freeze at a certain temperature, i'm not sure if the exact temp for jet B but i know its -47C for jet A-1.

As for lubricants, well you have to remember that the engine is an immense mechanical machine and it has lots of moving parts that have to operate to very high standards for long periods of time. The lubricants are in place to help these parts move with ease the way they were intended. They are also designed to withstand very low temperatures. One of the big brands used in the commercial aviation sector is Aeroshell lubricants.

I hope this answer has helped you, just don't try adding any aviation fuels to your car - that could have disastrous effects, and also, it won't make your car fly! :-)

Answer 3

1) Fuel for running the engine/s.

2) Lubricants -

     Turbines/Gear Boxes - oils for lubricating and cooling.

     Wheels/bearings/hinges/control runs - greases

     Hydraulic Systems - Hydraulic oils

     Brake oils - for brake systems

Answer 4

if i start you out with a simpler question to find the answer to, would that help?

"why do they use fuel (gas) and lubricants in cars?" the uses are exactly the same no matter if it's a car or aircraft.
