Eagle Prototype Parts ReceivedDick, WD4FAB, mechanical engineer on the AMSAT Eagle satellite, reported the news that the Eagle Project has received the prototypes of the heat sinks that will be riveted into Eagle's high-power electronic modules to enable the dissipation from the power devices in those modules. Dick thanked the team, "The heat sinks were fastidiously machined
by our friends at Embry Riddle Aeronautic University, Daytona Beach, Florida.
This is the culmination of discussions started over a year ago. We are
very much What makes these heat sinks very special is that they are machined from a high thermal conductivity, 99% pure, aluminum. This alloy is 33% higher conductivity than alloy aluminum, and as such it is quite soft and difficult to machine. In addition, the surface finish of these parts is also demanding and Embry Riddle Aeronautic University has presented us with a superb product. Prior to launch, the heat sink module surfaces will be protected by a plastic film to protect the thermal conductive and radiative surfaces of importance, as they all are of delicate and soft alloys.
Dick, WD4FAB
