Why airbrakes?

I was surprised it took until the 2nd page to mention that you can increase the total volume of air to the entire system because your engine is constantly pumping air.

Bobtail, one trailer, two trailers, triples? You need more air? It'll build up in a few minutes.

 

I watched that Delta DC9 or 10 series lose all of it's fluid and actually got away with some lives saved after what they called a very difficult landing with a set of bawls that have to be seen to be believed how they pull THAT rabbit out of the hat to save lives on that doomed flying dutchmen with dead aboard.

I started thinking, you can store Air on a few small strong cylinders and distribute same around the aircraft the way we use Air in our Trucks. Essentially you can scoop air from outside and pressurize it a little bit more to stuff back into those cylinders for more use, probably enough can be mined from the atmosphere it's forcing it's way through at whatever speed it is so that no amount of leaks will kill the people inside of the plane.

When I sit and think about pressures in Air, consider this.

A Attack Submarine or better yet a Boomer with nuclear missiles, 10,000 tons of boom boom. They use a bank of cylinders yea big and tall and force thousands of tons of pressurized sea water out of the tanks until boat goes up. Seawater is 700 times the pressure of atmosphere at sealevel and much much more than that underwater.

How do we get away with offloading say 4000 tons of seawater in a timely manner with a pathetic set of cylinders at high pressure? Do they not understand they can only blow so much volume before literally getting asthma and stuck? Sunk before they can refill those banks?

 

Ive fought brake fires that threaten the entire load. Actual flame trying to set the tires to go kaboom and work it's way onto the 5th wheel that is rimmed in oh so juicy grease for it to feed and flare up and get strong.

Im sure we all know that once rubber tires catch flame you can only bury them with a few yards of dirt to put em out. Extinguishers wont be worth a #### against a set of burning duals that are now bombs ready to kill you by shredding your body with shrapel and metal.

 

Actually I think the only reason anyone lived was that a pilot instructor (a real trainer, not some Swift "trainer") was on board as a passenger. 184 of 196 people lived. It's actually an awesome story I watched on History Channel or something like that. You can read about it at https://en.wikipedia.org/wiki/United_Airlines_Flight_232 if you are so inclined.

 

I think the reason they won't use pneumatics in aeronautics is that at altitude pressure becomes a variable. What works at sea level might not work at 40k feet. Especially when you consider more precise adjustments. (1 degree of positive right aileron vs. full on lock the brakes)

Even if they came up with some sort of compensator, it would probably need constant calibration.

 

Flight 232 was a United DeathCruiser-10.

 

That's exactly what would happen.

 

Because

 

Hydraulic fluid has gotten to expensive, and brake wear i increased. With air brakes it is less expensive to hire a J.B Hunt, Schneider, SWIFT driver to blow hot air thru the lines for air brakes, or another option is to take your Mother-in law with you for air tank for brakes.LOL

 

All I could think of when I saw the title of the thread:


I realize not everyone will want to watch the entire cartoon, just watch the last 2 minutes, Bugs explains air brakes.
