AIRCRAFT SYSTEM 3SimplexThe term Simplex in aircraft systems has significantly been used in the turbine engine fuel system.Simplex fuel nozzle was one of the first types of nozzles to be used in turbine engines, and it was later replaced in most installations with a duplex nozzle, which was giving better atomization at idling and starting speeds. Up to date, the simplex nozzle is still applicable in several facilities in aircrafts. All the simplex nozzles consist of the nozzle tip, a strainer which is made up of a screen of fine-mesh, an insert and support[CITATION Ell17 \p 345 \l 2057 ].Gas turbines systems, particularly in the cases of aircraft engines, are greatly exacting their demands for fuel nozzles. That is due to the high velocity which is experienced in the combustion chambers in relation to the size of the combustion apparatus. For the purpose of promoting proper combustion very high levels of fuel, atomization must be achieved[CITATION Reg13 \p 254 \l 2057 ]. There are many challenges of attaining consistent good spray and atomization of the fuel. The diagrams below explains the simplex fuel nozzle into details.Fig 1;the siplex fuel layout source www.jetairgroup.com

Operating signals from electrohydraulic valve and signals from a linear varying differential transformer which is used in the monitoring of the valve operations mostly occur in a considerably different frequency spans and they are transferred concurrently on the ordinary wire[CITATION Phi \p 34 \l 2057 ]. Signal discrimination is usually accomplished by the application of capacitors and inductors which are connected in series and also by use
