2013.07.14 NEWS *Rick Maschek has completed fabrication of the avionics support “discs” that will be used for mounting the avionics components for the DSS DART rocket, which is targeted to have its maiden flight on July 20th (less the avionics package). The flight of the DART with the avionics is targeted for August 24th. *Rick has obtained suitable-sized aluminum plates for casting the new DD-Slot grain. The plates will act as formers for the sides of the two opposing slots. *Craig Peterson has kindly accepted the task of making a Retainer Ring for the Forward Bulkhead (FBH) of the DSS TM-4 motor. The rationale of using a Retainer Ring to hold the FBH (rather than direct FBH attachment to the casing) is to mitigate potential damage to the FBH in case of motor overpressurization. *The 7” (178mm) aluminum alloy tube for the DSS TM-4 rocket motor has been ordered, and is being shipped to Randy Dormans. Randy has kindly accepted the task of drilling the indexed holes for the Nozzle and FBH Ring attachments. *Vicente Alvero Zambrano has offered to conduct the propellant characterization “DoubleSShot Characterization of KNSB propellant with regard to curing rate and associated mechanical properties”. The intent of this research is to better understand the curing and slumping behaviour of KNSB, particularly with regard to variation with temperature. Vicente has already started to make the moulds for casting the specimens.

Markus reports “The mechanical construction is so far finished. I might change the stainless steel screws by aluminum screws to save as much weight as possible”. Photo of the Cosma prototype body has been posted in the DualSShot album.
