The combustion oscillations are measured by a spark plug sensor at 200kHz. The spark plug sensor with fast response is preferable due to the short timescale associated in supersonic combustors. Its high sensitivity to flame dynamics also provides additional information other than the wall pressure measurement at conditions when minor pressure change occurs. Nonlinear analysis is performed to evaluate the deterministic and random nature of transient flame dynamics. Strong deterministic behavior is observed for the first time that positively supports further evaluation and development of predictive flame dynamics model.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_26001011.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_26001011.pdf\">Read the full paper &gt; <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>H.
