Abstract

An aircraft having a supercharger installed from a retrofit kit and a retrofit kit for retrofitting a supercharger 24 in or below the separation space ( 21 ) of an aircraft engine compartment or nacelle which is made up of a supercharger ( 24 ), one or more mounting plates ( 26 ) ( 54 ) and a drive pulley assembly ( 35 ) ( 53 ). The kits can also include a mounting bracket ( 25 ) and front connector mounting ( 52 ).

Claims

exact text as granted — not AI-modified
1. A supercharger retrofit kit for attachment of an automotive supercharger to at least one of an aircraft engine and an aircraft engine mounting within an engine compartment of an aircraft comprising:
 a supercharger including an impeller, a pulley assembly means for connection of the aircraft engine accessory drive to the supercharger impeller for transferring rotary motion from an aircraft engine accessory drive to the supercharger impeller, the combination being presized for installation in or below the separation space of an aircraft engine compartment.  
 
     
     
       2. The supercharger retrofit kit of  claim 1  wherein the pulley assembly means includes an accessory drive pulley, a tension adjustment pulley, a drive shaft pulley, a belt and a mounting plate. 
     
     
       3. The supercharger retrofit kit of  claim 1  wherein the pulley assembly further includes attachment means for connecting the mounting plate to at least one of the aircraft engine and the engine mounting tubing. 
     
     
       4. The supercharger retrofit kit of  claim 1  wherein the pulley assembly includes a mounting bracket. 
     
     
       5. The supercharger retrofit kit of  claim 2  further including a supercharger front connector mounting means for attaching the supercharger to the engine mounting. 
     
     
       6. The supercharger retrofit kit of  claim 5  wherein the supercharger front connector mounting means includes a ring portion to which extensions are attached. 
     
     
       7. The supercharger retrofit kit of  claim 5  wherein the supercharger front connector mounting means includes a plurality of bases, each base having an extension. 
     
     
       8. The supercharger retrofit kit of  claim 7  wherein the supercharger front connector includes three bases. 
     
     
       9. The supercharger retrofit kit of  claim 1  wherein the pulley assembly means is attachable to the crankcase of the at least one engine. 
     
     
       10. The supercharger retrofit kit of  claim 9  wherein the pulley assembly means is attachable to the crankcase proximate to the at least one engine's front end. 
     
     
       11. The supercharger retrofit kit of  claim 10  wherein the pulley assembly means is attachable to the air conditioning attachment points of the at least one engine. 
     
     
       12. The supercharger retrofit kit of  claim 1  wherein the pulley assembly means is attachable to the crankcase of the at least one engine proximate to the engine's rear end. 
     
     
       13. The supercharger retrofit kit of  claim 1  includes a first pulley assembly presized to be attachable to the accessory drive of a Lycoming engine, a drive shaft assembly connecting the first pulley assembly to a second pulley, the second pulley assembly including a mounting plate means for connection to a supercharger. 
     
     
       14. The supercharger retrofit kit of  claim 1  wherein the engine cowling or nacelle remains unmodified after installation of the supercharger. 
     
     
       15. An aircraft comprising at least one engine compartment having a separation space and a retrofit supercharger from a kit attached to the at least one of an engine and an engine mounting and positioned within or below the separation space, the supercharger including an impeller, a pulley assembly means for connection of the aircraft engine accessory drive and the supercharger impeller for transferring rotary motion from an aircraft engine accessory drive to the supercharger impeller, the combination being installed in or below the separation space of the aircraft engine compartment. 
     
     
       16. The aircraft of  claim 15  wherein the pulley assembly means includes an accessory drive pulley, a tension adjustment pulley, a drive shaft pulley, a belt and a mounting plate to which each of the pulleys is attached. 
     
     
       17. The aircraft of  claim 15  wherein the pulley assembly further includes attachment means for connecting the mounting plate to at least one of the aircraft engine and the engine mounting tubing. 
     
     
       18. The aircraft of  claim 15  wherein the pulley assembly includes a mounting bracket. 
     
     
       19. The aircraft of  claim 15  further including a supercharger front connector mounting means attaching the supercharger to the engine mounting. 
     
     
       20. The aircraft of  claim 19  wherein the supercharger front connector mounting means includes a ring portion to which extensions are attached. 
     
     
       21. The aircraft of  claim 19  wherein the supercharger front connector mounting means includes a plurality of bases, each base having an extension. 
     
     
       22. The aircraft of  claim 20  wherein the supercharger front connector includes three bases. 
     
     
       23. The aircraft of  claim 15  wherein the pulley assembly means is attached to the crankcase of the at least one engine. 
     
     
       24. The aircraft of  claim 22  wherein the pulley assembly means is attached to the crankcase proximate to the at least one engine's front end. 
     
     
       25. The aircraft of  claim 23  wherein the pulley assembly means is attached to the air conditioning attachment points of the at least one engine. 
     
     
       26. The aircraft of  claim 15  wherein the pulley assembly means is attached to the crankcase proximate to the engine's rear end. 
     
     
       27. The aircraft of  claim 15  wherein the engine cowling or nacelle remains unmodified after installation of the supercharger. 
     
     
       28. A supercharger retrofit kit for attachment of an automotive supercharger to at least one of an aircraft engine and an aircraft engine mounting within an engine compartment of an aircraft comprising:
 supercharger including an impeller, a pulley assembly means for connection of the aircraft engine accessory drive to the supercharger impeller for transferring rotary motion from an aircraft engine accessory drive to the supercharger impeller, the combination being presized for installation in or below the separation space of an aircraft engine compartment, and at least one of a mounting plate and a mounting bracket.
