NOZZLE EVALUATION.
Abstract
This quarterly report describes progress made during the period 22 June through 21 September 1963 on the program to evaluate experimental rocket motor nozzles produced under the Army Materials Research Agency Program. During this period, the Army Missile Command 29amicom0 delivered to Thiokol Chemical Corporation one Atlantic Research 2-in. pyrolytic graphite coated nozzle insert and two titanium boronitride Calorobic 1-in. nozzle inserts, numbered HTB-3 B 109 and HTD-3 A 7, respectively. AMICOM has approved the use of the TX-24 motor to test the 1-in. nozzles at chamber pressures of 700 psi or lower. The TX-338 test motor will be used for testing 1- or 2-inch nozzle inserts at chamber pressures exceeding 700 psi. Two test plans, A and B, were submitted by Thiokol to AMICOM for AMRA's consideration. Test Plan A was a comprehensive plan which included pretest and posttest evaluations of the nozzle insert. Test Plan B was submitted basically as a go-no-go tye test in which the insert would be shipped to Watertown Arsenal for evaluation after the test. (Author)
