Ranken dart
open-in-new
<h2 id="design">Design</h2> <p>The Ranken dart consisted of a tinplate tube 23cm long, with a cast iron pointed nose at one end, and a plug and three spring loaded arms at the other. The arms were kept closed in storage by means of a cap, either tin or rubber, which acted as a buffer when the dart was in its dropping tube. When released, the arms opened up and locked in place to act as a grapnel, thus ensuring that the body entered the fabric. The Dart contained high explosive, black powder and phosphorus which were ignited when the head penetrated the airship's outer skin.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h3>Further reading</h3> <ul><li>Castle, I.
