1. A self locking nut and bolt assembly for coupling a stack of rotating wheels, the assembly comprising: a tie bolt configured to extend through the stack of rotating wheels, the tie bolt comprising bolt threads thereon;a locking nut positioned on a first end of the tie bolt, the locking nut comprising nut threads engaging the bolt threads; anda locking washer positioned on the first end of the tie bolt and within the locking nut, the locking washer comprising washer threads engaging the bolt threads;wherein the locking washer and the locking nut pull the bolt threads in opposite directions to lock rotation of the tie bolt relative to the locking washer and the locking nut; andwherein a portion of the locking washer is staked into one or more staking slots of the locking nut to lock rotation of the locking washer relative to the locking nut. 2. The self locking nut and bolt assembly of claim 1, wherein the locking nut and the locking washer share the bolt threads and are forcibly abutted against one another to pull the bolt threads in opposite directions. 3. The self locking nut and bolt assembly of claim 1, wherein the first end of the tie bolt comprises a forward end of the tie bolt. 4. The self locking nut and bolt assembly of claim 1, wherein the locking nut comprises a forward flange extending about a forward end of the locking nut. 5. The self locking nut and bolt assembly of claim 4, wherein the forward flange comprises a tab extending radially outward and configured to engage a notch defined in a forward wheel of the stack of rotating wheels to lock rotation of the tab. 6. The self locking nut and bolt assembly of claim 1, further comprising an aft nut assembly positioned on a second end of the tie bolt. 7. The self locking nut and bolt assembly of claim 1, wherein the one or more staking slots extend in a radial manner along a forward end of the locking nut. 8. The self locking nut and bolt assembly of claim 1, wherein the locking nut comprises a bore surrounding the tie bolt. 9. The self locking nut and bolt assembly of claim 1, wherein the locking nut comprises a cut out receiving the locking washer. 10. The self locking nut and bolt assembly of claim 1, wherein the locking washer comprises a washer bore surrounding the tie bolt. 11. The self locking nut and bolt assembly of claim 1, wherein the locking nut comprises a super alloy material. 12. The self locking nut and bolt assembly of claim 1, wherein the locking washer comprises a malleable material for staking. 13. The self locking nut and bolt assembly of claim 1, wherein the locking washer comprises a first material, wherein the locking nut comprises a second material, and wherein the first material has a greater malleability than the second material to facilitate staking. 14. A compressor assembly for a gas turbine engine, the assembly comprising: a stack of rotating compressor wheels;a tie bolt extending through the stack of rotating compressor wheels;the tie bolt comprising bolt threads thereon;a locking nut positioned on a front end of the tie bolt;the locking nut comprising nut threads engaging the bolt threads; anda locking washer positioned on the front end of the tie bolt and within the locking nut;the locking washer comprising washer threads engaging the bolt threads;wherein the locking washer and the locking nut pull the bolt threads in opposite directions to lock rotation of the tie bolt relative to the locking washer and the locking nut; andwherein a portion of the locking washer is staked into one or more staking slots of the locking nut to lock rotation of the locking washer relative to the locking nut. 15. The compressor assembly of claim 14, wherein the locking nut and the locking washer share the bolt threads and are forcibly abutted against one another to pull the bolt threads in opposite directions. 16. The compressor assembly of claim 14, wherein the locking nut comprises a forward flange extending about a forward end of the locking nut. 17. The compressor assembly of claim 16, wherein the forward flange comprises a tab extending radially outward, and wherein a forward wheel of the stack of rotating compressor wheels comprises a notch receiving the tab to lock rotation of the locking nut. 18. The compressor assembly of claim 14, wherein the one or more staking slots extend in a radial manner along a forward end of the locking nut. 19. The compressor assembly of claim 14, wherein a forward wheel of the stack of rotating compressor wheels comprises a wheel bore, and wherein the locking nut is received within the wheel bore. 20. The compressor assembly of claim 14, wherein the locking washer comprises a first material, wherein the locking nut comprises a second material, and wherein the first material has a greater malleability than the second material to facilitate staking.
