摘要:
The rate of combustion of an electrically operated propellant having a self-sustaining threshold of at least 1,000 psi is controlled to produce chamber pressures that are sufficient to produce a desired pressure profile in the airbag to accommodate a range of human factors and crash conditions yet never exceeding the self-sustaining threshold. The combustion of the propellant is extinguished to control the total pressure impulse delivered to the airbag. Propellants formed with an ionic perchlorate-based oxidizer have demonstrated thresholds in excess of 1,500 psi and higher.
摘要(中):
控制具有至少1,000psi的自持阈值的电动推进剂的燃烧速率以产生足以在气囊中产生期望压力分布的腔室压力以适应一系列人为因素和碰撞状况,但从未 超过自我维持的门槛。 推进剂的燃烧熄灭,以控制输送到气囊的总压力脉冲。 用离子高氯酸盐基氧化剂形成的推进剂已经证实超过1500psi或更高的阈值。
