The complicated shape optimization of BWBUG is significant for improving its hydrodynamic efficiency while it has to require huge computation time and efforts. A novel surrogate-based shape optimization (SBSO) framework is proposed to deal with the BWBUG shape optimization problem for improving the optimization efficiency and quality. During the optimization search, the parametric geometric model of the BWBUG is constructed depending on seven specific sectional airfoils, with the planar surface being unaltered. Moreover, an improved ensemble of surrogates based global optimization method using a hierarchical design space reduction strategy (IESGO-HSR) is used for optimizing the chosen sectional airfoils. The optimum shape of BWBUG can be obtained using all sectional airfoils which are successfully optimized. The maximum lift to drag ratio (LDR) of the optimal BWBUG is improved by 24.32% with acceptable computational resources. The optimization results show that the proposed SBSO framework is more superior and efficient in handling the BWBUG shape optimization problem.<\/jats:p>","DOI":"10.1177\/0036850420950144","type":"journal-article","created":{"date-parts":[[2020,9,10]],"date-time":"2020-09-10T02:05:47Z","timestamp":1599703547000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Shape optimization of a blended-wing-body underwater glider using surrogate-based global optimization method IESGO-HSR"],"prefix":"10.1177","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8716-6174","authenticated-orcid":false,"given":"Pengcheng","family":"Ye","sequence":"first","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an, Shaanxi, China"},{"name":"Key Laboratory for Unmanned Underwater Vehicle, Northwestern Polytechnical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1932-8252","authenticated-orcid":false,"given":"Guang","family":"Pan","sequence":"additional","affiliation":[{"name":"School of Marine Science and Technology, Northwestern Polytechnical University, Xi\u2019an, Shaanxi, China"},{"name":"Key Laboratory for Unmanned Underwater Vehicle, Northwestern Polytechnical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,9,9]]},"reference":[{"key":"bibr1-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijnaoe.2017.08.002"},{"key":"bibr2-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1016\/j.oceaneng.2014.02.002"},{"key":"bibr3-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1109\/JOE.2012.2236152"},{"key":"bibr4-0036850420950144","doi-asserted-by":"publisher","DOI":"10.2514\/1.G002891"},{"key":"bibr5-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1016\/j.oceaneng.2011.09.001"},{"key":"bibr6-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1016\/j.asoc.2016.01.038"},{"key":"bibr7-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1016\/j.oceaneng.2018.03.055"},{"key":"bibr8-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1109\/JOE.2012.2227551"},{"key":"bibr9-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1515\/ijnaoe-2015-0069"},{"key":"bibr10-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1007\/s13344-017-0081-7"},{"key":"bibr11-0036850420950144","doi-asserted-by":"publisher","DOI":"10.1007\/s00158-018-1906-6"},{"key":"bibr12-0036850420950144","doi-asserted-by":"publisher","DOI":"10.2514\/1.29958"},{"key":"bibr13-0036850420950144","unstructured":"XFOIL.
