Abstract : Two Techniques were used to produce all of the test specimens and rocket nozzle inserts as required by the contract. All the test specimens, the HTB-2 and three of the HTB-3 rocket nozzle inserts were made by the conventional method in accordance with specifications. A proprietary method involving core heating was used to produce nine of the one-in. throat diameter HTB-3 rocket nozzle inserts and ten of the two-in. throat diameter HTB-4 nozzles in accordance with specifications. With the latter method which initially demonstrated the feasibility of the concept and subsequently involved a scale up of the operation, the appropriate apparatus was designed, constructed and placed into operation.
