The Response of an Energewtic Material Due in an External Stimulus (De responsie van energetische materialen als gevolg van externe opwarming).
Abstract
Within the scope of the project 'Feasibility study of an IM-ignitor' research has been carried out to develop a new ignitor to be used in a rocket system. In this project many aspects have been highlighted, especially on the area of Cook-off. The aspects of interest for Cook-off, the Thermal Initiation project, will be described in this report. With the computer models, partly developed during the feasibility-project, combined Thermal/chemical and thermal/chemical/pressure calculations have be performed and compared with experimental results. Using the Tarver-McGuire reaction kinetics with combined pressure simulation good results have been accomplished. The temperature distribution calculations gave a good insight in the temperature gradients of the test item and the time and temperature to explosion were fully in agreement with the experimental values. Using a pressure calculation in combination with a thermal/chemical calculation, a much better stopping criterion for a simulation is found than in a simple thermal/chemical calculation and is more in agreement with the experimental results.
