were estirpated to be each about a quarter mile from II. At
recovery on 5 October I was, by fix, 2500 feet from II and
III was 2000 feet from II.
Drogue I travelled an apparent 9.2 miles during 20.55
hours —an indicated speed of 0.45 mph. Drogue II travelled
an apparent 8.8 miles during 20.9 hours, for an indicated
speed of 0.42 mph. Drogue III travelled an apparent 9.0 miles
in 20.75 hours, giving an indicated speed of over 0.43 mph.
The chronology of fixes during this run waso
4 Oct. 1227 #1, II, III, IV, V 41051.21, 87~29.0 (set)
1730 #II 41052 21, 87~30.81 (fix)
#1 41052.21, 87031.01 (estimated)
#III 41052.3', 87030.81 (estimated)
5 Oct. 0900 #I 41057.61, 87033.9' (fix) (recovery)
0912 #III 4158.1, 87~33.31 (fix) (recovery)
0922 #II 41057.7', 87~33.4' (fix) (recovery)
The wind regime for this run was:
3 Oct. NW 20 knots (on east side of lake)
4 Oct. SE 10-12 k
5 Oct. S 10 k (becoming 14 k later in day)
Drogue run, 9-10 October 1963 Fig. 5) This run involved
one radio drogue (IV) that was used to home the ship into radar
range.
Drogues II, III, IV, and V were set at 0920 on 9 October;
setting position, by radar fix, was 41051.5', 87~29.3'. Drogues
III and IV were normal surface drogues, each carrying a single
sheet metal drag; drogue II carried two current drags in tandem.
This configuration of drags was a test (reported later) to ascertain whether windage on the drogue floats was significant.
