よって機体を反対方向へ進行させるようになっている。This vibratory compaction machine is equipped with eccentric pendulums mounted on a pair of parallel shafts with their installation angles 90 degrees out of phase with each other. When the excitation force of the eccentric pendulum is the same diagonally upward and downward, the resultant force causes the aircraft to move forward or backward, and if necessary, the phase of one of the eccentric pendulums is switched by 180" by external operation. The aircraft is designed to move in the opposite direction.
