Rotary valve for pulse detonation engines
First Claim
1. In a pulse detonation engine including a tube having a forward end and an aft end, a rotary valve comprising:
- a rotor rotatively mounted in said forward end of said tube, said rotor having a plurality of internal flow passages formed therein; and
a plurality of transfer plenums for receiving fuel and air arranged around said rotor, wherein said flow passages will periodically establish fluid communication between said tube and said transfer plenums as said rotor rotates.

Abstract
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.
