Abstract
A method of manufacturing a channeled wall fluid apparatus (2) is disclosed. The method includes the step of providing at least one rib (16) on one of either a liner (8) having a length or an interior surface of at least a first mold (18). The method also includes the step of placing the first mold around the liner to form a gap (78) between the first mold and the liner. A removable casting material (24) is inserted within the gap. The method also includes removing the removable casting material from within the gap to form at least one channel (14) extending at least a portion of the length of the liner.
Claims23
A method of producing a thrust nozzle, the method comprising the steps of:
- (a) forming a thrust nozzle liner having an outer surface and a length;
- (b) forming at least a first shell having an interior and an exterior surface;
- (c) providing at least one rib on one of either of the thrust nozzle liner or the first shell;
- (d) placing the first shell around the outer surface of the thrust nozzle liner, such that the at least one rib extends between the outer surface of the thrust nozzle liner and the interior surface of the first shell to form a gap therebetween;
- (e) inserting a removable casting material within the gap, wherein the removable casting material is a gas;
- and
- (f) removing the removable casting material from within the gap to form at least one channel extending at least a portion of the length of the thrust nozzle liner.
A method of forming a thrust nozzle, the method comprising the steps of.
- (a) forming a thrust nozzle liner having an outer surface and a length;
- (b) forming at least a first shell having an interior surface and an exterior surface;
- (c) providing at least one spacer means on one of either the thrust nozzle liner or the first shell;
- (d) placing the first shell around the outer surface of the thrust nozzle liner, such that the at least one spacer means extends between the outer surface of the thrust nozzle liner and the interior surface of the first shell to form a gap therebetween;
- (e) inserting a removable casting material within the gap, wherein the removable casting material is a gas;
- and
- (f) removing the removable casting material from within the gap to form at least one channel extending at least a portion of the length of the thrust nozzle liner.
A method of manufacturing a channeled wall nozzle, the method comprising the steps of;
- (a) providing at least one spacer on one of either a nozzle liner or an interior surface of at least one shell, the nozzle liner having an exterior surface and a length;
- (b) placing at least one shell around the nozzle liner to form a gap between the at least one shell and the nozzle liner;
- (c) filling the gap with a removable casting material, wherein the removable casting material is a gas;
- and
- (d) removing the removable casting material to form at least one channel extending at least a portion of the length of the nozzle liner.
A method of manufacturing a thrust nozzle, the method
- (a) providing at least one rib on an exterior surface of a nozzle liner having a length;
- (b) placing first and second shells around the nozzle liner to form a gap between the nozzle liner and the first and second shells;
- (c) filling the gap with a removable casting material, wherein the removable casting material is a gas;
- and
- (d) removing the removable casting material to form at least one channel extending at least a portion of the length of the nozzle liner.
