The Technique Studies on Stability of Rocket Ejection Seat
The stability is one of the most important criterion for performance evaluation of a rocket ejection seat, and it is also the key research object in ejection seat development. On ejection, especially on high speed ejection, the ejection seat without good stability may bring about a serious consequence of going beyond the physical endurance limit because of the sharp rotation of the seat-man system, and may even cause the seat-man-parachute entanglement, which will lead to failure of lifesaving. According to the feature of the ejection seat, this paper studies the stability of three different concepts: drogue chute, stabilizing fins and stabilizing booms. It presents the theoretical simulation or test results, using several parameters such as the three-axial angular velocity and MDRC( Multi-axes Dynamic Response Criterion) to research the high-speed stability for each device, which provides a theoretical basis to the concept selection for the new generation of the rocket ejection seat.
