The effects of tandem-wing (TW) interactions on the aerodynamic performance of dragonfly hovering have been investigated. Numerical simulations of single-wing hovering without interactions and TW hovering with interactions are conducted and compared. It is found that the TW interactions reduce the lift coefficient of FW and HW by 7.36% and 20.25% and also decrease the aerodynamic power and efficiency. The above effects are mainly caused by the interaction between the vortex structures of the FW and the HW, which makes the pressure of the wing surface and the flow field near the wings change. During the observations of dragonfly flight, it is found that the phase difference (\n            <jats:italic>\u03b3<\/jats:italic>\n            ) is not fixed. To explore the influence of phase difference on aerodynamic performance, TW hovering with different phase differences is studied. The results show that at\n            <jats:italic>\u03b3<\/jats:italic>\n            = 22.5\u00b0, dragonflies produce the maximum lift which is more than 20% of the body weight with high efficiency; at\n            <jats:italic>\u03b3<\/jats:italic>\n            = 180\u00b0, dragonflies generate the same lift as the body weight.\n          <\/jats:p>","DOI":"10.1098\/rsos.202275","type":"journal-article","created":{"date-parts":[[2021,8,25]],"date-time":"2021-08-25T07:07:58Z","timestamp":1629875278000},"page":"202275","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["Tandem-wing interactions on aerodynamic performance inspired by dragonfly hovering"],"prefix":"10.1098","volume":"8","author":[{"given":"Liansong","family":"Peng","sequence":"first","affiliation":[{"name":"School of Energy and Power Engineering, Beihang University, Beijing 100191, People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengzong","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Energy and Power Engineering, Beihang University, Beijing 100191, People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9158-8262","authenticated-orcid":true,"given":"Tianyu","family":"Pan","sequence":"additional","affiliation":[{"name":"Research Institute of Aero-Engine, Beihang University, Beijing 100083, People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guanting","family":"Su","sequence":"additional","affiliation":[{"name":"School of Energy and Power Engineering, Beihang University, Beijing 100191, People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiushi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Energy and Power Engineering, Beihang University, Beijing 100191, People's Republic of China"},{"name":"Research Institute of Aero-Engine, Beihang University, Beijing 100083, People's Republic of China"},{"name":"Key Laboratory of Fluid and Power Machinery, Ministry of Education, Xihua University, Chengdu 610039, People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.1984.0051"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.2307\/2420733"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.109.1.379"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1088\/1748-3190\/aa5761"},{"key":"e_1_3_6_6_2","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2015.0389"},{"key":"e_1_3_6_7_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.200.3.543"},{"key":"e_1_3_6_8_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.218552"},{"key":"e_1_3_6_9_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0266467409006087"},{"key":"e_1_3_6_10_2","first-page":"063102","article-title":"Effects of phase lag on the hovering flight of damselfly and dragonfly","volume":"6","author":"Zou PY","year":"2019","unstructured":"Zou PY, Lai YH, Yang JT. 2019 Effects of phase lag on the hovering flight of damselfly and dragonfly.
