Abstract: A vehicular gas turbine engine includes a first electronic controller responsive to a plurality of engine operating parameters and associated with a power relay box to control operation of engine functions and further includes a manual controller that allows open loop operation of the engine to start and run it at a speed and power level independent of the electronic controller and associated signals of engine parameters. The manual controller includes a timer set to shut the engine down after a preselected time period of manual operation to prevent excessive use of the open loop control thereby to minimize possibility of engine damage.

Abstract: A diffuser-burner casing in the combustion section of an axial flow gas turbine engine transmits axial engine loads between the compressor section and the turbine section and serves as a housing for the combustion chamber assemblies and as a bearing support for the shaft or shafts extending between the compressor and turbine sections. The casing has outer, intermediate and inner ring portions structurally interconnected for limited flexure under the influence of thermal gradients and stresses. The outer ring portion is connected to the intermediate ring portion by means of a frustoconical wall portion which defines the forward part of an annular plenum in which the combustion chamber assemblies are located. The intermediate ring portion and the inner ring portion are interconnected by means of a plurality of circumaxially spaced struts, and form the diffuser for the compressor which discharges into the annular plenum containing the combustion chamber assemblies.

Abstract: An integral mechanical governor for controlling the speed of prime movers, such as steam turbines is disclosed as a separate structure that can be mounted on and coupled to the shaft of the associated prime mover. The device includes a housing having at least one end opening and closure means for the open end of the housing, the housing and closure defining a governor assembly chamber and a sump for lubricating fluid. The end wall remote from the open end has an inboard bearing means for rotatably mounting a driven shaft disposed to extend from the governor assembly chamber through the bearing to the exterior of the housing to permit said driven shaft to be coupled to the shaft of the prime mover when the integral mechanical governor is mounted thereon in assembled position.
