Air brake - Wikipedia, the free encyclopedia Air brake (aircraft) — In aeronautics these are a type of flight control system used on aircraft to reduce speed. Air brake (rail) — On larger road vehicles and railways this is a type of brake operated by compressed air. Air brake (cartoon) — In cartoons these are a type of flight control system used on aircraft to halt the aircraft in mid-descent, usually mere inches above the ground. en.wikipedia.org /wiki/Air_brake   (184 words)

Air brake (rail) - Wikipedia, the free encyclopedia On railways an air brake is a brake operated by compressed air. A safer air brake was patented by George Westinghouse on March 5, 1872. In the air brake's simplest form, compressed air pushes on a piston in a cylinder. en.wikipedia.org /wiki/Air_brake_(rail)   (746 words)

Air Brakes Page   (Site not responding. Last check: 2007-11-06) The air pressure forces the piston to move against the spring pressure and causes the brake blocks to be applied to the wheels. Air will continue to pass from the auxiliary reservoir to the brake cylinder until the pressure in both is equal. The brake valve is fitted with a pressure sensitive valve which allows a reduction in brake pipe pressure according to the position of the brake valve handle selected by the driver. www.railway-technical.com /air-brakes.html   (3265 words)

LOCOMOTIVE ENGINE Running and Management - THE WESTINGHOUSE AIR-BRAKE. The brakes are released by again admitting pressure into the main brake-pipe from the main reservoir; which pressure, being greater than that of the auxiliary reservoir, forces the piston 5 back to the position shown in the engraving, recharges the reservoir, and at the same time permits the air in the brake-cylinders to escape. To apply the brakes gently, a slight reduction is made in the pressure in the main brake-pipe, which moves the piston down slowly until it is stopped by the graduating spring 9. The cavity b connects the passage h to the atmosphere; the piston 13 is raised by the cylinder pressure beneath it, and the valve 18 by the spring 20. www.catskillarchive.com /rrextra/chapt21.Html   (5979 words)

Air Brake System All brakes on a vehicle and on a trailer (when one is used) are operated together by a brake valve. The brakes are applied by depressing the brake pedal (also called the foot valve, or treadle valve) that gives the operator control of the air brake system. When the brake pedal is engaged, air from the air tanks flows through the brake pedal valve through the brake lines to the brake chambers close to the wheel brakes that contain flexible diaphragms. www.tpub.com /eqopbas/38.htm   (851 words)

Florida Commercial Driver Handbook - Air Brakes   (Site not responding. Last check: 2007-11-06) Air brakes are a safe way of stopping large vehicles if the brakes are well maintained and used right. Air brake systems are three braking systems combined: the service brake system, the parking brake system, and the emergency brake system. A leak in the air brake system which causes all the air to be lost will also cause the springs to put on the brakes. www.hsmv.state.fl.us /handbooks/Commercial/3section_205.html   (4286 words)

air brake --  Encyclopædia Britannica When air pressure in the brake pipe is reduced, air is automatically admitted into the brake cylinder. Among these are air brakes, including flaps and spoilers; reversible-pitch propellers; thrust reversers; and deceleration parachutes, also called brake or drogue chutes. Includes reports on the estimated annual emissions of air pollutants from individual sources, annual summaries of air pollution measurements at different monitoring stations, maps depicting the areas of the country where air pollution levels exceed health-based EPA standards, and other air pollution data. www.britannica.com /eb/article-9005194?tocId=9005194&query=air   (887 words)

Operation Air Brake   (Site not responding. Last check: 2007-11-06) Air brakes out of adjustment constitute the major defect type that results in vehicle being taken out of service (40%). Out of adjustment air brakes reduce the braking capacity for large vehicles and further inhibit their stopping distance, which under ideal conditions is already twice as far as that for cars and other smaller vehicles. Most self adjusting brakes require several brake applications of at least 80 psi to adjust properly. www.highways.gov.sk.ca /docs/trucking/transport_compliance/Operation_airbrake.asp   (252 words)

Westinghouse Works, 1904   (Site not responding. Last check: 2007-11-06) The first air brake invented by George Westinghouse revolutionized the railroad industry, making braking a safer venture and thus permitting trains to travel at higher speeds. In addition, the company manufactured equipment necessary for brakes, such as a friction draft gear, and also evolved from making the air brake to manufacturing an electro-magnetic brake. The town of Wilmerding, popularly known as "the home of the air brake," became centered around the workings of the Westinghouse Company, as its fortunes rose and fell with that of the company. memory.loc.gov /ammem/papr/west/westair.html   (270 words)

Air Disc Brake Dilemma Air discs with electronics are all the rage in Europe. And while the air disc with electronic braking controls has become the standard tractor braking system with every truck maker across the pond, the only electronically controlled braking systems (ECBS) operating on this side of the Atlantic are in some high-profile demonstrations, run by technology leaders such as US Xpress of Tunnel Hill, Ga. Szapacs adds another maintenance benefit: "(A drum brake's) additional maintenance cost — and also a safety issue — is in a leaking wheel seal that allows the oil to saturate the brake lining causing a pulling in the steering. www.heavydutytrucking.com /2003/01/048a0301.asp   (1583 words)

Air brake (aircraft) - Education - Information - Educational Resources - Encyclopedia - Music   (Site not responding. Last check: 2007-11-06) In aeronautics air brakes (sometimes called "spoilers" or "lift dumpers") are a type of flight control used on aircraft to reduce speed during landing. Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, spoilers greatly reduce lift while making little change to drag. On landing, the deployment of these spoilers causes a dramatic loss of lift and hence the weight of the aircraft is transferred from the wings to the undercarriage, allowing the wheels to be mechanically braked with much less chance of skidding. education.music.us /A/Air-brake-(aircraft).htm   (355 words)

Air Brake Adjustment   (Site not responding. Last check: 2007-11-06) Air brakes should be adjusted in the shop with the wheels off the ground according to the manufacturer's instructions. Ideally you should bring the free play in the arm down to 3/8" and the adjusting arms should all be at the same angle with the same pressure applied.

Re: Air brake usage during descent   (Site not responding. Last check: 2007-11-06) The inboard ones can also rise in flight for air brake use but are limited to only half way. To further complicate matters, if the spoilers are up on both sides being used as air brakes in descent, then you may see spoilers on one side partially retract as they also perform the roll function at the same time. And if you think this is complicated, on a 777 (and maybe others) both the outboard and inboard ailerons droop to supplement the flaps when they are down, yet also continue to act like ailerons when required. www.talkabouttravelling.com /group/rec.travel.air/messages/534475.html   (421 words)

Berkshire Scenic Railway Museum Education George Westinghouse invented the first version of the air brake in 1869 when he was just 22 years old. Without air brakes, the engineer had little control over his train and it was not uncommon for the brakeman to lose fingers or be crushed between the cars. To apply the brakes, the engineer reduces the pressure in the pipe and a value directs the greater pressure in the tank to a cylinder that applies the brakes. www.berkshirescenicrailroad.org /education.php   (7600 words)
