First Claim
Patent Images
1. An ignition system comprising:
- a pilot-catalyst section along a longitudinal axis;
a pilot inlet in communication with said pilot-catalyst section to receive a propellant;
a main catalyst section in a staged relationship with said pilot-catalyst section along said longitudinal axis;
a main inlet in communication with said main catalyst section to receive the propellant;
wherein said pilot-catalyst section includes a pilot catalyst bed;
wherein a pilot outlet is downstream of said pilot catalyst bed relative to said longitudinal axis, said main catalyst section in communication with said pilot outlet;
wherein said pilot-catalyst section includes a pilot regenerative cooling jacket, said pilot catalyst bed in communication with said pilot inlet via said pilot regenerative cooling jacket; and
wherein the main catalyst section includes a main catalyst bed, and wherein the main catalyst section includes a main regenerative cooling jacket, said main catalyst bed in communication with said main inlet via said main regenerative cooling jacket, and wherein said main catalyst bed is in communication with said pilot outlet.
