do airplanes have breaks like in a car so they can stop on the runway thing easier?

Answer 1

Of course airplane have brakes like cars do. It´s just that they´re more rugged, stronger and bigger. The only difference is that they´re used at the very end of the landing run.

Since airplane speeds are higher, using just the brakes to slow the aircraft down would cause the brakes and wheels to overheat and ignite. So aerodynamics brakes are used to slow the aircraft down to a speed in which applying the brakes would be safe.

Answer 2

Aw, for the love of,... This is a joke, right?

Yes and no.

All aircraft since about WWI have had wheel brakes in a really cool transformation that allowed some aviation technology to surpass the automotive technology it was originally based on.

Aircraft were the first known vehicles to employ what you could get away with calling an anti-lock braking system, or ABS. It's called anti-skid, and the technology under the dash of your car borrows from them rather than vice versa. In the interests of saving weight, disc brakes were develloped by aircraft manufacturers and are now a part of almost every vehicle manufactured.

Duly noted, reverse thrust is used on many aircraft, both prop and true turbine, greatly assisting in the short field landing characteristics of everything from piston singles to turbo props and true jets.

The Cessna 150, which was first introduced in the 1950's, had disc brakes, which you wouldn't see as standard in automotive applications until the 1970's.

The aircraft of the early years of flight didn't require brakes because they were taking off and landing at aerodromes for the most part, which were more or less a patch of smooth grass with a half mile radius, and used a tail skid instead of a tail wheel, which helped them stop and keep in a straight line on landing. Some of those can still be seen flying at Rheinbeck, the oldest dating back to about 1909, presumably with a replacement tail skid.

Modern aircraft stop all the time on the ground. They stop on that taxiway thing for traffic as they arrive or depart, they stop on that runway thing to await take-off clearance. The inertia for the stop doesn't come from the pilots sticking their heads out a window and exhaling expansively.

Don't even start me on seaplanes or float planes.

Answer 3

Mechanical thrust is given interior the process the exhaust that's quickly linked to the engine of the airplane for which it would not require any kit shift. Gears are in certainty used to transmit potential. Wheels of an plane basically roll mutually as the airplane is beginning up. although, they do have brakes.

Answer 4

Yes, they have brakes, but the main thing that slows the plane down is the engines reverse thrusters. basically, when the plane first touches down with rear wheels AND the front wheel, the exhaust from the engines are redirected either forward or up/down, not out the back. At the same time the engines are revved up to increase the reverse thrust effect, the breaks are applied to the wheels. The reason the rev the engines is to provide more reverse thrust AND in case there is a problem, they will need the horsepower to make an immediate take off, all they need to do at that point is redirect the exhaust back to rear normal position.

Answer 5

Yes. Larger aircraft have the equivalent of anti-lock brakes. To save wear on the brakes, larger aircraft also have thrust reversers, which use the engines to slow the plane down.

Answer 6

Not all jet transport aircraft have thrust reversers (e.g BAe 146) and in those that do, most of the retarding force comes from the wheel brakes.

From a design point of view the critical case for brake energy absorption is usually the rejected take off from V1 at maximum take off weight, in which case reverse thrust is not accounted for in the calculations (since following an engine failure on a twin engine aircraft only one reverser would be available anyway).

The wheel brakes on most large aircraft have anti skid (anti lock) and in many types the brakes can be set to operate automatically on landing or rejected take off

Answer 7

Yes they have brake systems. They have wheel brakes like a car, but their main speed reducer is Reverse Thrusters.

Which means, the loud Air / Engine noise you hear right after touch down is the reverse thrusters. Plates / diffusers direct the engine thrust forward to slow the plane down. (Jets).

Planes that have props use similiar technology by pitching the pop blades on different angles.

When the plane slows enough, then they use the wheel brakes.

Answer 8

Yes, they have brakes like a car. How else would they stop in such a short distance. They have HUGE brakes though which are very powerful. But all in all they stop the wheels like brakes stop the wheels on your car.

Answer 9

yes but airplanes mainly rely on thrust reversal mechanisms to do most of the slowing upon landing. brakes are applied only when the plane slows to a certain speed otherwise they would just burn up due to high temperatures caused by too much friction.

Answer 10

They have brakes, but most of the stopping is done by reversing the thrust. When you land, metal hoods drop down and redirect the jet thrust forward.
