multifunction coupling contains the same function parts in mirror image so that in the coupled state of the installed generator the electrical and the fluid streams can flow unimpeded the coupling half on the generator can either be a flange like integral component of the generator or it can be mounted on it as a separate component the connection of the couplings provides a multifunctional connection that self locks the two halves together while providing a fluid electrical connection between the respective modules whereby the respective lines are run out the back for coupling if the generator installed in the electrical generator unit has to be removed and or replaced with another generator the generator need only be disconnected from the locating plate whereby the respective connections can be designed simply and do not require complicated installation or removal this produces a considerable simplification of the maintenance of such componentry since the generator can be designed in a modular manner and can simply be removed for maintenance by a simple removal from the generator side locating plate to enable the connection of the electrical and fluid lines between the locating plate on the engine side and the non rotating areas in the engine the locating plate is arranged on a stator of the jet engine whereby the stator comprises hollow ribs through which electrical and or fluid lines can be passed in particular the heat sensitive electrical line can be passed through the hollow cavities with additional heat.
