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 Thermalchemical and thermalchemicalpressure 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 thermalchemical calculation, a much better stopping criterion for a simulation is found than in a simple thermalchemical calculation and is more in agreement with the experimental results.
