Abstract
Drive means for connecting a gas turbine engine to its accessories are so constructed as to allow the accessories to be selectively positioned to any one of several predetermined circumferential positions about the perimeter of the engine. This feature permits convenient mounting of the same engine upon vehicles demanding radically different engine mounting arrangements.
Claims5
A gas turbine engine comprising:
- a core engine including a core shaft;
- a nacelle partially circumscribing said core engine;
- first gear means within said core engine and driven by said core shaft;
- a plurality of circumferentially spaced hollow struts extending radially between said core engine and said nacelle and in general axial alignment with said first gear means;
- convertible accessory means disposed external to said nacelle and in general alignment with one of said struts;
- and
- drive shaft means, one end of which is drivingly connected to said accessory means, and the other end of which includes a second gear means insertable into any of said hollow struts and into driving engagement with said first gear means, and
- wherein said first gear means and said second gear means may be disengaged by withdrawing said drive shaft means radially outwardly with respect to said core shaft.
