Application of Anova to pulse detonation engine ground demonstrator's dynamic performance measurements

Application of Anova to Pulse Detonation Engine ground demonstrator's dynamic performance measurement is being explored due its large data of chamber pressure at station 1 (Pi) fluctuations resulting in thrust deteriorations. It has lead to quantifying engine functionality, while operating at varied frequencies during various phases of engine operations. After evaluating the performance, the causes of chamber pressure fluctuations were identified using multiple independent analysis techniques. Further, procedures of improving it by applying corrections were enforced in the areas of relevant area, which are also covered in the paper. This produced encouraging results in improving P1 and helped in upscaling efforts in a significant manner in short span of time. The current paper deals in the details of Anova implementation and systematic identification of key areas of improvements. These enhancements were carried out after careful selection of plans in the engine ground demonstrator, ground rig and instrumentation setup etc. It also yielded better reproducibility of performance and optimization of main subsystems of PDE. Further, this will also contribute to reduce the development cycle and trial complexity also, if researchers continue to extract concern areas to be addressed.
