while the apogee aiticude and, consequently,

the upper aor baliiscic portion of the trajectory was estizacred correctly,
poracclers eich were used to obtain the trajectory were in error.

First-

stage burmeut velocity, although unterestincted, had been compensated by
undgerestizacion of second-stage draz coefficient.

‘Nind data which were ob-

tained are presented aod discussed in Sectiun 5.3.

UWi-Lo Rocket Performance

e

Estizating perforaance of the Hi-Lo rockets proved tu be the oust difficule problea encountered on this phase of the program.

Because of late

entry of the Hi-Lo project into che programa, the MIDVT tracking system was
not equipped to track these addicicnal units.

Enough equipment was added

to MIDOT, however, cto peroit Crackiag of two of the eight Hi-Lo rounds.

It

was then ancicipated that the two knven trajectories sould be combined with
the theoretical perfornance parameters and used to estimate probuble trajec-

tories of the untracked units.

For raasons which willbe discussed later,

MIDOT trajectories were obtained oa only one round eacn for both che Teak
and Orange shots.

Estimates were then anode as planned of trajectories of

the untrackead vehicles.
