- 175: PropVanes, Site tower, Sun 17-Mar-2002 11:32:59 MST, 20m prop down again
The 20 meter prop failed at 13:30 MST March 16.
- 168: PropVanes, Site tower, Wed 13-Mar-2002 14:00:40 MST, several things
Swapped out bad prop at 20m with "spare". Used the same prop (pitch=306) and reset the boom angle to 177.5 deg as the prop we pulled.
At the same time, cleaned the krypton at 20m.
Also took a core sample near rad stand.
- 165: PropVanes, Site , Fri 08-Mar-2002 13:24:24 MST, 20 meter prop out
The 20 meter prop is questionable.
This occurred at ~12:00, noon, local.
- 159: PropVanes, Site tower, Wed 27-Feb-2002 14:32:19 MST, 20 m propvane reinstalled
At 14:15 the 20 m propvane was reinstalled.
Propvane 005 with prop FLOSS 5, #56159
Back at trailer the wind dir/spd dispay showed reasonable values.
- 155: PropVanes, Site tower, Mon 25-Feb-2002 15:07:49 MST, Reinstalled 1 m propvane
Atempted to reinstall propvane # 004 /prop 56153 but spinning prop broke. Blood!
At 14:45 installed propvane #007 / prop 53560
Now there is only one spare propvane with matching prop
- 152: PropVanes, Site tower, Fri 22-Feb-2002 11:20:47 MST, Remove 1m propvane
At 09:35 I removed the 1m prop vane to take to NCAR for repairs
- 144: PropVanes, Site tower, Tue 19-Feb-2002 18:06:15 MST,
An attempt was made to fix the 0.5m propvane by swapping parts:
The end result was to have a valid speed but no direction.
The components are #4 chopper and prop and vane and electronics and
#7 encoder.
Since the encoder is different, the boom azimuth will have to be reset (but
direction isn't working now anyway).
Summary:
Either chopper read 0 through #7's electronics.
Either encoder read constant through #4's electronics.
Thus, the problem has to be with the electronics?
The 20m propvane was brought down to be taken to NCAR.
- 135: PropVanes, Site tower, Sun 17-Feb-2002 07:49:58 MST, 20m prop speed decoder out
The 20 meter prop speed is zero starting at Feb 14 14:00 MST
The prop at 20 meters has been replaced before, see entry #103
- 103: PropVanes, Site tower, Fri 04-Jan-2002 15:50:49 MST, 20m Prop Replaced
01/04/2002 ~15:00
We replaced the prop at 20m which had the speed out.
At 15:50 local I changed the boom angles in the sensor per
the logbook entry. Prior to that the direction angle was
out by 180-degrees after we put in the new sensor.
