The head consists of two parts: the front assembly (skull and skin) and a rear assembly
(skull cap). The rear assembly may be removed by unscrewing the four M5x12 button
head  cap  screws  located  at  the  rear of  the head.  The  head skin and  skull  are  molded
together and cannot be separated. Inside the head is a large cavity which may be used to
mount various types of instrumentation. The standard arrangement is to have the head
mounting  block  bolted  in  the  head  which  will  accept  3  uni-axial  accelerometers.
Optionally a bracket for combined accelerometer-angular rate sensor application (020-
1014) can be used.
