| Popis: | 104 This research analyzes C28 Fuse Igniter Composition Combustion Properties standing in different environments, including the flame burning rate, sensitivity and generation temperature and pressure. The igniter composition is B (Boron), Red Lead(Pb3O4) with glue (Viton). The mixing ratio is B: Pb3O4 = 10: 90. Two experimental model sare used to distinguish between open and closed ignition. This composition can be ignited under different environments using an auto- transformer and timer to control the input voltage and power-on time. The generated temperature and pressure are captured after rapid combustion using the fine style exposed K Type thermocouple and piezoelectric crystal sensor. The physical energy is transferred into a high transient data acquisition system for storage and analysis. The original igniter composition ratio was set at 3% of the variation in conditions as a reference. Different igniter composition formulation proportions were entered into the NASA-Lewis Code (CET86) data repository format, with the balanced combustion thermodynamic theory calculations for subsequent experimental verification. High-speed cameras were used to capture the rapid burning process within a few milliseconds. We will place a copper plate under the bottom of the quartz tube, measuring the copper temperature back after ignition, using the developed recursive formula estimation Kalman filtering technique. The reverse heat transfer estimate theory is used to estimate the copper effect on the front of the rapid pulse combustion flame heat flux. The measured and simulated temperatures are compared. Experimental verification of the process measuring and thermodynamic properties data analysis establish an important arms development work product research reference. |
