Performance of a smart direct fire penetrator using a ram air controlled mechanism

The effectiveness of a direct fire penetrator projectile equipped with an actively
controlled ram air mechanism is investigated through dynamic simulation. The ram
air control mechanism consists of a rotary sleeve valve which directs air flow from
an inlet at the center of the nose to side ports. The projectile dynamics, the inertial
measurement unit and the control system are included in the system model. It is
shown that the ram air control mechanism provides sufficient control authority to
significantly reduce dispersion of a direct fire penetrator. The effects of
accelerometer and gyroscope bias and noise are investigated. It is seen that
moderate values of bias and noise do not affect the dispersion significantly. But
with higher values the dispersion is greater than the dispersion for the free flight. / Graduation date: 2002
