Pulse detonation engines and components thereof
First Claim
1. A pulse detonation engine comprising:
- a primary air inlet;
a primary air plenum located in fluid communication with the primary air inlet;
a secondary air inlet;
a secondary air plenum located in fluid communication with the secondary air inlet, wherein the secondary air plenum is substantially isolated from the primary air plenum;
a pulse detonation combustor comprising a pulse detonation chamber, wherein the pulse detonation chamber is located downstream of and in fluid communication with the primary air plenum;
a coaxial liner surrounding the pulse detonation combustor defining a cooling plenum, wherein the cooling plenum is in fluid communication with the secondary air plenum;
an axial turbine assembly located downstream of and in fluid communication with the pulse detonation combustor and the cooling plenum; and
a housing encasing the primary air plenum, the secondary air plenum, the pulse detonation combustor, the coaxial liner, and the axial turbine assembly.
