AISI1075 detention behaviors in high temperature environment

Abstract

The objective of this paper is to study behaviors of detention made by AISI1075 in high temperature environment. The detention is used to hold the rocket until the rocket launched. The rocket launched with salvo type. Therefore detentions get high temperature from exhaust gas at 1,200 Celsius blow from rockets. There are the criteria are selection and evaluation, the initial torque for tightening the detention arm. In addition to avoid the failure of material and initially-tightened torque, the understanding of the structural load on the detention is significant. As the initial investigation, this paper presents the experiment test of detention including load behavior on guide knob and on the detention arm. The initially-tightening torques for the detentions were varied from 25 - 40 N.M. The results showed that detention made by AISI1075 with initial-tightened torque 32 N.M. maintain the rocket with force greater than 17,500 N.
