Subject field(s)
  • Traction (Rail)
CONT

Power Control. The diesel engine in a diesel-electric locomotive provides the drive for the main alternator which, in turn, provides the power required for the traction motors.... So, if we want more power from the motors, we must get more current from the alternator so the engine needs to run faster to generate it. Therefore, to get the optimum performance from the locomotive, we must link the control of the diesel engine to the power demands being made on the alternator. In the days of generators, a complex electro-mechanical system was developed to achieve the feedback required to regulate engine speed according to generator demand. The core of the system was a load regulator, basically a variable resistor which was used to vary the excitation of the generator so that its output matched engine speed.

CONT

Combined hybrid. Combined hybrid systems have features of both series and parallel hybrids. They incorporate power-split devices allowing for power paths from the engine to the wheels that can be either mechanical or electrical. The main principle behind this system is the decoupling of the power supplied by the engine... from the power demanded by the driver.

CONT

In a series hybrid-electric vehicle all energy supplied by the non-reversible source (combustion engine or fuel cell) is converted into electricity. The wheels are always driven by the electric motor ... In a parallel hybrid-electric vehicle most of the mechanical energy supplied by the combustion engine is transferred to the wheels by a mechanical transmission. In addition or alternatively ... the wheels are also driven by the electric motor ... A combined hybrid combines characteristics of the two configurations described above.

  • Aircraft Systems
CONT

Normal fuelling is accomplished through dual fuel nozzle adapters located on the right wing leading edge spar at the fuelling stations. All fuelling operations, except fuel pump control, are accomplished at the fuelling station. Opening the station access door applies DC power to the fuelling system and removes the N3 inhibit to the centre tank fuel pumps. Fuel flows through the dual nozzles to pressurise a fuelling manifold. Fuelling valves control the flow of fuel from the fuelling manifold into each of the three switches on the fuelling panel. A fuel quantity may be preselected for each tank. The fuelling valves close automatically when the preselected quantity is reached or when the tank is full, whichever occurs first. A tank overfill system is provided to prevent fuel spillage. If any fuel is sensed in the surge tanks during fuelling, a signal is sent to close all fuelling valves. The aircraft is filled automatically by hydrant or tank truck pressure. All tanks may be fuelled at the same time. The main tanks may also be fuelled manually through over wing fill ports. There are no over wing fill ports for the centre tank.

SIR... stands for Standard Interface Rack. SIR is a system for integrating hardware. It is a technology we use to take Earth things to space. The rack contains mechanical parts, called a liner, used to slide drawers in and out, much like a file cabinet. Drawers are used to contain or repackage things and make them flight ready. For example, we can’t take computers to space in the same outer packages or cases we use on Earth because some pieces may float out or the vibration from launch would destroy them. So, we take all the computer's guts from the central processing unit(its brain) and repackage it in one of these drawers. On the rack side, the SIR also provides power and data for the drawers through cables. Power for a drawer comes from a connector in the rack, just like a wall outlet at your house. Data cables serve many purposes, but the main one is for communication. This is so drawers can "talk" to each other, the Space Station, and Earth. For the computer drawer mentioned above, parts are wired to connectors in the drawer. When you slide the drawer into the rack, it connects to cables already in the rack.
