A Stationary Engine Mounting.
Fig. 121.—Stationary engine mounting.
A mounting used for a 70 h.p. air-cooled Renault, which is designed to be supported by short lengths of steel tube projecting from the crank case, is shown by [Fig. 121], this particular arrangement being used on a propeller biplane. The four ash longerons of the nacelle are built up in the form of a box girder, the struts immediately under the engine bearers being reinforced with steel plates. The steel tubes from the crank case embedded in a steel bearing, composed of two semi-circular clips, which are let into the upper longerons, and are prevented from moving sideways by steel collars sweated to the tubes and abutting against the fixing clips. In this case, by the removal of the four fixing clips and the necessary pipe connections, the engine can be lifted bodily out.
