<p>Ein <b>Townend-Ring</b> ist eine Motorverkleidung (<a href="Cowling" title="Cowling">Cowling</a>) für einen <a href="Sternmotor" title="Sternmotor">Sternmotor</a>. Dabei wird ein aerodynamisch geformter Ring oberhalb der Zylinderköpfe des Motors befestigt.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
Dies sorgt für einen definierten Luftstrom durch den Motor und die Verringerung von Verwirbelungen, ohne die Kühlung dadurch zu verschlechtern.
</p><p>Benannt ist er nach seinem Entwickler Hubert Townend,<sup id="cite_ref-Hansen_2-0" class="reference"><a href="#cite_note-Hansen-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> der für das Britische <a href="National_Physical_Laboratory" title="National Physical Laboratory">National Physical Laboratory</a> arbeitete. Das Patent wurde am 10. Juli 1928 in Großbritannien angemeldet.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>
</p>
<p>Die Idee des Townendringes wurde mit der <a href="NACA-Haube" title="NACA-Haube">NACA-Haube</a> vollendet. Townendringe werden heute nicht mehr angewendet. Sie kamen nur in den <a href="1920er" title="1920er">1920er</a> und <a href="1930er" title="1930er">1930er</a> Jahren zum Einsatz.
