|Completed Kit Leonardo Da Vinci Aerial Screw|
Always on the lookout for possible visual aids for aviation history presentations I came across a kit for an “Aerial Screw”, a design that Leonardo Da Vinci had drawn up but never built. Leonardo was a man of many talents especially for such famous paintings as the Mona Lisa and the Last Supper. Born in 1452 his idea for a helicopter was way ahead of its time considering the first successful man carrying helicopters did not fly until the 1940’s.
|Parts for the Kit|
The kit is produced by the Pathfinders company in Canada along with many other wood kits. I was really impressed how well the parts were cut out from wood with a smooth finish and no sanding marks or laser burns. For me the instructions were pretty good but dimensions are in centimeters so a ruler with metric scale is needed. Working over the Thanksgiving holiday I had the kit assembled within three days using the white glue that is provided with the kit.
Turning a crank the upper screw part of the model turns. Leonardo thought that four men could be turning cranks to produce enough thrust to lift a full-size Aerial Screw. We know now that would be possible.
