Tested the v4 and v5 igniter. All were with v4 except Run 3 which used the v5 igniter (and didn't work). See the discussion on the main page for more details. Update 2012-06-08: I originally used the wrong GOX temperature to calculate the mass flow and mixture ratio. As a result, the values were a lot lower than intended which explains the weak plume seen in the photos and videos.

Augmented Spark Igniter Tests 2012-02-05

Tested two versions (short and long) of the v2 igniter. Runs 1-3 were with the short body version (0.75 inch shorter chamber) and Runs 4-5 were with the long body version. See the discussion on the main page for more details. Update 2012-06-08: I originally used the wrong GOX temperature to calculate the mass flow and mixture ratio. As a result, the values were a lot lower than intended which explains the weak plume seen in the photos and videos.

Tested the new v1 igniter four times. For the first two runs, there is no visible plume, only a slight darkening in the still images. See the discussion on the main page for more details. Update 2012-06-08: I originally used the wrong GOX temperature to calculate the mass flow and mixture ratio. As a result, the values were a lot lower than intended which explains the weak plume seen in the photos and videos.
