This paper outlines the application of such a system via a Post-Buckled Precompression (PBP) technique at the end of a twist-active piezoelectric rotor blade actuator. The basic performance of the system is handily modeled by using laminated plate theory techniques. A dual cantilevered spring system was used to increasingly null the passive stiffness of the root actuator along the feathering axis of the rotor blade. As the precompression levels were increased, it was shown that corresponding blade pitch levels also increased. The PBP cantilever spring system was designed so as to provide a high level of stabilizing pitch-flap coupling and inherent resistance to rotor propeller moments. Experimental testing showed pitch deflections increasing from just <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mrow><mml:msup><mml:mrow><mml:mn>8<\/mml:mn><\/mml:mrow><mml:mo>\u00b0<\/mml:mo><\/mml:msup><\/mml:mrow><\/mml:math> peak-to-peak deflections at 650\u2009V\/mm field strength to more than <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mrow><mml:msup><mml:mrow><mml:mn>26<\/mml:mn><\/mml:mrow><mml:mo>\u00b0<\/mml:mo><\/mml:msup><\/mml:mrow><\/mml:math> at the same field strength with design precompression levels. Dynamic testing showed the corner frequency of the linear system coming down from 63\u2009Hz (3.8\/rev) to 53\u2009Hz (3.2\/rev). Thrust coefficients manipulation levels were shown to increase from 0.01 to 0.028 with increasing precompression levels. The paper concludes with an overall assessment of the actuator design.<\/jats:p>","DOI":"10.1155\/2012\/832939","type":"journal-article","created":{"date-parts":[[2012,4,5]],"date-time":"2012-04-05T22:27:46Z","timestamp":1333664866000},"page":"1-10","source":"Crossref","is-referenced-by-count":5,"title":["Solid State Adaptive Rotor Using Postbuckled Precompressed, Bending-Twist Coupled Piezoelectric Actuator Elements"],"prefix":"10.1155","volume":"2012","author":[{"given":"Ronald M.","family":"Barrett","sequence":"first","affiliation":[{"name":"Department of Aerospace Engineering, University of Kansas, 2120 Learned Hall, 1530 W 15th Street, Lawrence, KS 66045-7621 , USA"}]},{"given":"Ryan","family":"Barnhart","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering, University of Kansas, 2120 Learned Hall, 1530 W 15th Street, Lawrence, KS 66045-7621 , USA"}]}],"member":"311","reference":[{"issue":"10","key":"1","doi-asserted-by":"crossref","first-page":"1373","DOI":"10.2514\/3.9792","volume":"25","year":"1987","journal-title":"AIAA Journal"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1080\/15376490801907855"},{"issue":"10","key":"39","doi-asserted-by":"crossref","first-page":"859","DOI":"10.1177\/1045389X9700801005","volume":"8","year":"1997","journal-title":"Journal of Intelligent Material Systems and Structures"},{"key":"41","doi-asserted-by":"publisher","DOI":"10.1177\/104538903039261"},{"key":"50","doi-asserted-by":"publisher","DOI":"10.1088\/0964-1726\/15\/5\/022"},{"key":"51","doi-asserted-by":"publisher","DOI":"10.2514\/1.21292"},{"key":"52","doi-asserted-by":"publisher","DOI":"10.1088\/0964-1726\/16\/3\/042"},{"key":"55","doi-asserted-by":"publisher","DOI":"10.1115\/1.4001202"},{"volume-title":"Micromechanical behavior of a lamina","year":"1975","key":"56"}],"container-title":["Smart Materials Research"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/archive\/2012\/832939.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2012\/832939.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2012\/832939.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T07:47:39Z","timestamp":1607586459000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/smr\/2012\/832939\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,4,5]]},"references-count":9,"alternative-id":["832939","832939"],"URL":"https:\/\/doi.org\/10.1155\/2012\/832939","relation":{},"ISSN":["2090-3561","2090-357X"],"issn-type":[{"type":"print","value":"2090-3561"},{"type":"electronic","value":"2090-357X"}],"subject":[],"published":{"date-parts":[[2012,4,5]]}}}
