Данная задача возникает при исследовании обтекания крылового профиля потоком газа. В работе методом вспомогательных функций получена новая теорема единственности решения этой задачи с видоизмененным условием Франкпя для такого типа задач, без каких-либо ограничений, кроме гладкости, на эллиптическую часть границы области.</p></abstract><trans-abstract xml:lang="en"><p>The article deals with the boundary-value problem for mixed type equations with Neumann boundary conditions in a mixed area for the Chaplygin equation. This problem arises in the study of a gas flow around an airfoil. While using the method of auxiliary functions the authors obtain a new uniqueness theorem to solve this problem with the modified Frankl condition for this type of problems without any restrictions other than smoothness on the elliptical part of the border area.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод вспомогательных функций</kwd><kwd>уравнение Чаплыгина</kwd><kwd>условие Неймана</kwd><kwd>уравнения смешанного типа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>method of auxiliary functions</kwd><kwd>the Chaplygin equation</kwd><kwd>the Neumann condition</kwd><kwd>mixed type equations</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">Сабитов К.
