In some older aircraft, the bottom section is used instead ("heel brakes"). Levers are used in a few aircraft. Most aircraft are capable of differential braking. [1] Thrust reversers, that allow thrust from the engines to be used to slow the aircraft. Air brakes, dedicated flight control surfaces that work by increasing drag.
A speed hill, also known as a high-speed float, [17] is an airtime element commonly found in Bolliger & Mabillard steel coasters and Rocky Mountain Construction wooden coasters. The element is a mini-version of camelback entered at a high speed, which results in significant negative G-forces that exceed a typical camelback.
Caster flutter can be controlled by adding dampers or increasing the friction of the swivel joints. [3] This can be accomplished by adding washers to the swivel joint. The friction increases as the weight on the front of the chair increases. Anytime the caster begins to flutter, it slows the chair and shifts weight to the front wheels.
Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...
