3.6 Rocket motor assembly test/Drogue release mechanism test. Ten drogue release mechanisms
shall be assembled onto an explosives vacated WORD rocket motor in order to test: (1) the WORD
rocket motor assembly, (2) the drogue release mechanism. The government shall provide such motors.
Performance shall be in accordance with paragraph 3.7. Testing shall be in accordance with paragraph
4.5. See test definitions in sections 6.4 and 6.5.
3.7 Drogue release mechanism performance . The drogue release test configuration shown in Figure
1 shall be employed. The drogue release mechanism shall actuate within 400 to 1,000 psig and shall in
no way hinder deployment of the WORD rocket motor in any configuration/load arrangement.
