Regroup for next firing 
Saturday, April 25, 2009, 08:31 AM
The Computer team has gotten back together to review needed changes in support of the upcoming test firing (May 30/31). We need to redo some actuators, develop and test out a LOX load level indicator system, change our switch box to support more 24v lines, test out an updated igniter system, rework the ignition sequence to ensure we have combustion of the motor within a specified time window, and finally we need to perform end to end testing.

Finalizing configuration

Things are looking good for the next test firing in May. The Prop team fixed the leaking LOX valve. The computer team did some additional testing. Tweaked a few parameters for optimizations, but essentially it is ready to go.

Tweaks and fixes

During the test firing in November we burnt up one of the Accelerometers (it was mounted close to the mouth of the motor). So we wired up a new Accelerometer. The Prop team tweaked the main valve actuator so that it take ~3 seconds to open. We modified the LabVIEW code to take this into account to determine when to turn off the ignitor.
