only had one stable positions It was assumed that the warheads could re-enter
the atmosphere at 80 km altitude with any angle of incidence. Section Noe 2
(Aerodynamics) supplied the cw .y values dependent an C 9 perhaps based on
measurements in the wind tunnel of this section,, and also the other necessary
aerodynamic data. The oscillations of the angle of incidence decreased quite
quickly in all case o not remember the loss of range anymore'

The warheads of the R-10. RR12c and R-14 were constructed in such a way a e
the heating effects were not critical fir the above'-mentioned 25X1
