&lt;p&gt;A variety of engines were fitted to the DC-3 throughout the course of its development. The original civilian aircraft used Wright R-1820 Cyclone 9s, but later aircraft (and the majority of military ships) used the Pratt &amp;amp; Whitney R-1830 Twin Wasp radial which offered better high-altitude and single engine performance. A few Pratt &amp;amp; Whitney R-2000 radials saw use.&lt;/p&gt;
&lt;p&gt;The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s. The R-1820 was built under license by Lycoming, Pratt &amp;amp; Whitney Canada and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov OKB was formed to produce the engine as the M-25.&lt;/p&gt;
&lt;p&gt;The R-1820 was at the heart of many famous aircraft including the early Douglas airliners (prototype DC-1, the DC-2, earliest civilian versions of the DC-3, and the limited-production DC-5), B-17 Flying Fortress and SBD Dauntless bombers, the early versions of the Polikarpov I-16 fighter (as M-25), and the Piasecki H-21 helicopter.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>How many different engines were installed on the C-47/DC-3 Aircraft</title><link>http://www.flightglobal.com/airspace/groups/i_love_radial_engines/forum/p/68784/76878.aspx#76878</link><pubDate>Sun, 17 Oct 2010 22:47:07 GMT</pubDate><guid isPermaLink="false">633cdc99-ba90-4fab-88e4-2ee78cef1809:76878</guid><dc:creator>flyvertosset</dc:creator><slash:comments>0</slash:comments><comments>http://www.flightglobal.com/airspace/groups/i_love_radial_engines/forum/p/68784/76878.aspx#76878</comments><wfw:commentRss>http://www.flightglobal.com/airspace/groups/i_love_radial_engines/forum/commentrss.aspx?PostID=76878</wfw:commentRss><description>&lt;p&gt;Let us know what radial engines you know about , flying on the DC-3/C-47&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
