Winter work week summary

The winter break work week was overall a success. Several issues arose with parts being ordered and building the power supply to run the motor in the tunnel but solutions were found and we have moved on.

The week started with the finalization of all aero numbers and then moving the model from XFLR5 to ProE. A few fit checks were done and the model was ready to be printed for construction.

Work first began on the fuselage. Plywood sheeting was laminated with cross sections of the fuse, then cut out and assembled on a base board. Pink foam was used to fill the gaps and then the never ending process of whittling away then sanding and painting the positive molds began. From this the negative fiberglass molds were laid. Further work needs to be done to create the support mold for the negative mold, since scaling up the previous plaster method proved not to work.

In parallel work was being done on the wings, thanks to Jim we now have a full construction model of the wings ready to be sent to the laser cutter. This model was also given to Neil who is now running ANSYS to better determine the wings strength characteristics.

The propulsion group continues to trouble shoot issues with the power, a solution has been found and we now only are waiting for parts. While waiting Aaron was able to setup the Eagle Tree flight computer on the Red ARF plane.
