Lean Burn = higher air-fuel ratio, Less power, more economical Rich Burn = lower air-fuel ratio, More power, less economical
All aircraft, not just jets, have shapes as streamlined as possible to enable them to fly faster and use less fuel.
Pressurization is for the comfort of crew and passengers. The planes fly higher to save on fuel. The less dense air higher up causes less drag. It is also unfortunately harder to breathe. Pressuriziation makes it easier to breathe without special equipment, like breathing apparatus or oxygen.
Paper burns faster as there is less mass to burn and less energy in paper, If it were wood, due to the mass of the wood it would burn Longer and brighter and less lengthened and less brighter for Cardboard.
Nitromethane works well. i ain't no chemists so I'll explain simply.. gasoline needs allmost 15 lbs. of air to burn 1 lb. of gas .. a nitromethane engine will need less than 2 lbs. of air to burn 1 lb. of methane , so you can put a little more than 7 times more fuel into the cylinder -- more fuel in cylinder =s more power..
Lean Burn = higher air-fuel ratio, Less power, more economical Rich Burn = lower air-fuel ratio, More power, less economical
Because the higher the altitude, the thinner the air, so the less work is needed by the engines. Sometimes there is also strong tailwinds which will speed it up. Also, this burns less fuel.
It is because the higher up the plane is, the lower the air pressure. When the air pressure is lower, there are less air molecules, resulting in less friction. Therefore it uses less fuel.
Higher is better.. Less fuel to spend and more fuel effeciency gets u further on less.
A small rocket might go higher because a smaller rocket has less weight
it depends, pilots fly airplanes at different altitudes depending on the weather systems around the area at the time. Most large aircraft or jumbo jets want to fly at altitudes exceeding 25,000 feet because at higher altitudes jumbo jets burn less fuel to go the same distance that it would take if it were flying at a lower altitude. I would estimate that passenger planes fly somewhere between 30,000 feet and 40,000 feet. Jumbo jets can't fly much higher because the air will become so thin that they can't climb and more. And much lower will require more fuel because the air is more dense.
Heyy I'm dum
Generally yes. There is less drag at higher altitudes, and thus better fuel economy, right up until the airplane can't get enough air to burn with with fuel to get the power needed to go faster and higher. Of course it takes extra fuel to get up there, so only long distance travel is done at high altitudes.
Kerosene isn't. However, jet fuel, kerosene, and diesel fuel all are very similar. They're less refined than unleaded fuel, and that reduces the risk of on-board fires, for one. Additionally, they burn at a higher BTU rate than unleaded/petrol fuels.
It usually depends on the make. Higher end props tend to be safer than jets because of all the problems that might occur on sophosticated aircraft, such as Jets.
A 747 gets slightly less than 1 mile per gallon of jet fuel.
