rocket, a gyro spin-up gas generator cartridge, and
a simple pitch rate gyro located forward of the
vernier rocket. The gyro comes up to operating
speed by the gas generator-driven gear rack as the
gyro is uncaged and the vernier rocket fires. The
vernier rocket burns during rocket sustainer stage

burning for approximately 0.3 second. Mounting
of the vernier rocket in the caged position allows
the nozzle thrust vector to be directed up through
the nominal cg of the occupied seat. If the seat
starts to pitch because of adverse torque of any
origin, the gyro precesses and rotates the vernier
