Pressurized windowed burner chamber performance for solid rocket propellant: Preliminary study

Aim: To investigate the performance of the strand burner chamber prototype. Material and Methods: Finite element analysis applies to design and evaluate the mechanical performance of materials and structures. Experimental studies perform to validate the FEA results and to get the burning rates and chamber pressure data. Research using Solidworks and ANSYS to Design the chamber. FEA and experimental results examined by equivalent stress, hot-fire test data, and visual data. Experimental studies conducted using a CW Laser coupling with Focus Lens to ignite the propellant strand. Quartz glass design with ASME BPVC standard for high-pressure sight windows. Hi-speed camera 600 frames/sec with 1.8 ND Filter Lens to measure the burning rates. Results: The lowest safety factor is 0.18, which is on the sight windows. During the experimental studies, pressure increasing gradually hereafter the ignition process. Then before the combustion process going to stop, the pressure gradually dropped. Suddenly the crack was discovered on the sight windows surface. Conclusion: The burning rate data cannot to perform because of the large number of combustion smokes. Further research strongly recommended using signal wire to obtain burning-rates data.
