Полученные результаты позволяют сделать вывод о перспективности технологии Digital Light Processing (DLP) и фотополимера HTM-140, их способности отвечать требованиям не только до- и трансзвуковых режимов в аэродинамической трубе, но и гиперзвуковых.</p></abstract><trans-abstract xml:lang="en"><p>The article briefly evaluates the use of 3D-printing to create size-similar models of rocket and spacecrafts' elements suitable for conditions of aerodynamic ground testing. The practices of NASA regarding generative technology for aerodynamics simulation are considered. The authors built a model using AGARD calibration models, 3D printer Ultra 2 of EnvisionTEC, Digital Light Processing (DLP) and pho-topolymer HTM-140. Next described step was model's fault detection and analyze of roughness of surface layer. The results obtained enable to conclude on the potential of Digital Light Processing (DLP) technology and photopolymer HTM-140, their ability to meet the requirements for not only sub- and transonic modes in a wind tunnel, but also hypersonic.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ракетно-космическая техника</kwd><kwd>аэродинамические модели</kwd><kwd>прототипирование</kwd><kwd>технологии Зп-печати</kwd><kwd>наземные испытания.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rocket and spacecrafts</kwd><kwd>aerodynamic model</kwd><kwd>prototyping</kwd><kwd>3D-printing technology</kwd><kwd>ground tests.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Charles G.
