Hi All, This is s 3d-printed model of the historic "Curtiss Number 3" engine that powered the AEA Silver Dart, as well as several other experimental craft. It wasn't a reliable engine, but it was an important step towards the development of reliable V-type aircraft engines in the US. The surviving engine is an important artifact in Canadian aeronautical history because it powered the first flights in Canada on Feb 23rd and 24th, 1909. The surviving engine is heavily deteriorated, and there is little archival evidence for certain missing parts, so this is a recreation. The model is based on a scan of the original artifact that was made at Canadian Aviation and Space Museum (CASM) on October 22nd of 2019 by members of the Ingenium conservation team. That scan provided dimensional information for a CAD model that I designed in Fusion 360. The model is published on Thingiverse, along historical details, instructions, and information on the project. The model can be printed using any reasonably recent and decently calibrated FDM printer. The version show above has both FDM and SLA-printed parts, as well as some scratch building for the pushrods and ignition cables. Thanks to everyone who provided information on the previous post. My image links disappeared, so I thought that I would repost the completed model with image links from a (hopefully) more reliable source. Below is information on the engine that I have compiled for future reference, and in case anyone would like to contribute further.
