A rotary valve for pulse detonation engines includes a rotor rotatively mounted in the forward end of the pulse detonation tube and a plurality of transfer plenums for receiving fuel and air arranged around the rotor and partially disposed over the forward end of the tube. The rotor has a plurality of internal flow passages formed therein which periodically align with a plurality of inlet ports formed near the forward end of the tube as the rotor rotates. Each one of the transfer plenums is aligned with a corresponding one of the inlet ports so that the flow passages will establish fluid communication between the tube and the transfer plenums when aligned with the inlet ports. Additional features include axial injection of the fuel-air mixture into the pulse detonation tube, pre-compression of the inlet flow and a drive system located outside of the primary gas path.

A drug packaging and delivery system comprising: a sheet feeder unit for feeding a packaging sheet; a packaging unit for forming bags in the packaging sheet, for feeding drugs into each of the bags, and for sealing the bags having the drugs therein so as to form a drug package sheet; a winder unit including a plurality of empty reels, said winder unit being adapted to wind a section of the drug package sheet onto each one of the empty reels so as to form a plurality of loaded reels; and a drug package feeder unit for unwinding the section of drug package sheet from each of the loaded reels and feeding the section of drug package sheet to a drug inspection device. 2. The drug packaging and delivery system of claim 1, wherein said winder unit includes: a driving unit for rotating each of the empty reels; and an empty reel stock compartment including a support plate for supporting the empty reels. 3. The drug packaging and delivery system of claim 2, wherein said winder unit further includes: a gate in said empty reel stock compartment, said gate being adapted to raise and lower so as to allow each of the empty reels to be moved from said empty reel stock compartment; and a loaded reel stock space for storing the loaded reels therein. 4. The drug packaging and delivery system of claim 1, wherein said drug package feeder unit includes: a rotary shaft for supporting the loaded reels so as to allow each of the loaded reels to rotate thereon; and a driving arm having a roller for contacting the section of the drug package sheet wound on a respective one of the loaded reels, said roller being adapted to rotate while contacting the drug package sheet wound on the respective one of the loaded reels so as to rotate the respective one of the loaded reels. 5. The drug packaging and delivery system of claim 4, wherein said drug package feeder unit further includes: pinch rollers for grabbing a tip of the section of the drug package sheet wound on the respective one of the loaded reels; and a curved support plate for guiding the tip of the section of the drug package sheet toward said pinch rollers as said roller rotates the respective one of the loaded reels. 6. The drug packaging and delivery system of claim 5, wherein said winder unit includes: a driving unit for rotating each of the empty reels; and an empty reel stock compartment including a support plate for supporting the empty reels. 7. The drug packaging and delivery system of claim 6, wherein said winder unit further includes: a gate in said empty reel stock compartment, said gate being adapted to raise and lower so as to allow each of the empty reels to pass from said empty reel stock compartment; and a loaded reel stock space for storing the loaded reels therein.
