Slow down there bud, it’s time to talk airplanes ✈️
Tonight’s chapter is 32, and it’s a big one with lots of different sections, so for tonight we’re just going to talk about one part of chapter 32 and that is Aircraft Brakes.
Aircraft have brakes installed on the main landing gear wheels. They can be made of either carbon, which is lighter and has a higher heat strength or steel which last longer but are heavier. Typically you’ll see carbon brakes installed.
A pretty steady theme will start to emerge as we talk about different systems and that is redundancy. The brake assembly has multiple pistons around the case, anywhere from 12-20, give or take depending on the aircraft, and these pistons are typically split between two hydraulic systems. Meaning if we loose one hydraulic system we still have braking power. On top of this, aircraft usually have a accumulator that stores reserve braking power, so if we loose all hydraulics, we will have at least 4-5 brake applications worth of stopping power. Redundancy. 😐 see told you I’d get there.
The brake itself is made of several rotors that slot into the wheel assembly and spin with the tire, when the brakes are applied these rotors are squeezed by several rows of stationary stators (get it? Stators are stationary and rotors rotate).
And when you change one of these heavy mofos you’ll definitely get dirty, so wear gloves......or don’t if you’re into that sort of thing.
Staying up through the night,
so you can fly Safe through the day
