Claims
- 1. An assembly of rotor discs at least one of which is removably mounted to another of said discs, away from potential fatigue points in said discs comprising:
- a) at least a pair of spaced joinable discs positioned to rotate about a common axis,
- b) a spacer arm extending between said discs in contact therewith, said spacer arm contacting a piloted joint in one of said discs under axial compression,
- c) each disc having a flange which extends between said discs toward the flange of said other disc and
- d) securing means to removably join said flanges under axial tension in a pre-loaded redundant support junction to also join said discs at a junction removed from said discs.
- 2. The assembly of claim 1 wherein the so joined flanges define a cylinder, which cylinder has vent holes therein.
- 3. The assembly of claim 2 wherein said spacer arm slants between said discs and relative to the so joined flanges and defines with said flanges, an annular cavity between said discs.
- 4. The assembly of claim 1 wherein each of said two discs are already joined to one or more other discs.
- 5. The assembly of claim 1 wherein said securing means are bolts or studs through bolt holes.
- 6. The assembly of claim 1 wherein said flanges have edges which are scalloped.
- 7. The assembly of claim 1 wherein said discs have rotor blades thereon.
- 8. A joining means for removable rotor discs located away from potential fatigue points in said discs wherein at least a pair of spaced joinable discs are positioned to rotate about a common axis, said joining means comprising:
- a) a spacer arm extending between said discs in contact therewith, said spacer arm contacting a piloted joint in one of said discs under axial compression,
- b) each disc having a flange spaced from the spacer arm, which flange extends between said discs toward the flange of said other disc and
- c) securing means to removably join said flanges under axial tension in a pre-loaded redundant support junction to thus remotely join said discs.
- 9. The joining means of claim 8 wherein said flanges thus joined, define a cylinder, which cylinder has a plurality of vent apertures therein.
- 10. The joining means of claim 9 wherein said spacer arm slants between said discs and relative to the so joined flanges and defines with said flanges, an annular cavity between said discs.
- 11. The joining means of claim 8 joining said discs which each are already joined to one or more other discs.
- 12. The joining means of claim 8 wherein said securing means are bolts or studs through bolt holes.
- 13. The joining means of claim 8 wherein said discs have rotor blades mounted thereon.
- 14. The joining means of claim 8 wherein said flanges have scalloped edges.
