Under the wing a retractable diving air brake was to be installed.
In addition, each car's air brake reservoir is divided into two portionsthe service portion and the emergency portionand is known as the dual-compartment reservoir.
While in this employment, the air brake was invented, and he became very interested in its development.
The air brake plugs the cylinder before piston impacts, trapping a small amount of air between the piston and cylinder.
In fact, three different types of air brakes were tried until one was found which was successful, and that is the one which is incorporated now in the aircraft.
They are hauled by certain specialised engines that are equipped with air brakes and a slow speed device for special running within the power station.
The connections typically consist of several air hoses for controlling the air brake system, and an electrical cable for the control of the traction equipment.
A compressed air brake system is divided into a supply system and a control system.
