| New for 2015 is a switch from welded steel to a bolted aluminum frame.
Due to university and client concerns, welded aluminum is not an
option for the engineering solution. After several proposed concepts
such as aluminum T-bar, square aluminum tubing, and bolted or glued
joints, the final choice was to use 1" round tubing riveted together
with sheet metal brackets. This option was borrowed from the
construction of lightweight aircraft and many of those design techniques were used as inspiration. |
