Abstract
A device for starting one of a plurality of airplane engines with a starter by way of hydrodynamic transmission elements or a hydrodynamic torque converter having arranged in parallel therewith an overriding clutch that is connected to each engine. The engines are adapted to be coupled to each other by means of transmission gearing and coupling means arranged behind the hydrodynamic transmission elements when viewed from the engine side. The hydrodynamic transmission elements are adapted by variation of the filling to be controlled in such a way that the power intake beyond a predetermined speed will increase at a lower rate.
Claims8
A device for starting one of a plurality of airplane engines that must become started during operation of several engines already started for normal running operation, which includes:
- starter means, hydrodynamic transmission means operatively connected to said starter means and connectable to each of the engines to be started, coupling means associated with said hydrodynamic transmission means for coupling the engines to be started to each other prior to starting, and control means associated with said hydrodynamic transmission means and operable after starting of engines to control the supply of actuating fluid to said hydrodynamic transmission means so as to cause the power input thereof from a predetermined speed on to adopt a predetermined behavior for starting an engine that became eliminated from normal running operation.
