    • An apparatus for the disposal of solid rocket motors which produce exhaustases containing flammable and/or explosive products. The solid rocket motor to be burned is first detachably connected to and inserted in one end of an elongated mixing chamber which has, at an opposite end, a multi-step expansion nozzle. The rocket motor is then ignited and the exhaust gas is passed into the mixing chamber, which is sufficiently large to reduce the velocity of exhaust gases from supersonic to subsonic. Air is injected into the mixing chamber to react with flammable and/or explosive products in the exhaust gases and the resultant mixture is then discharged from the mixing chamber through a multi-step expansion nozzle to expand the gaseous mixture and, at the same time, produce substantial turbulence within the gas mixture which is about six times higher than the turbulence levels produced by a constant area circular nozzle. The expansion nozzle has an inner wall with a stair-step shaped surface, having an aspect ratio of not less than 2 and not greater than 10, to create the increased turbulence levels within the multistep nozzle.
    • 一种用于处置固体火箭发动机的装置,其产生含有易燃和/或爆炸产物的废气。 待燃烧的固体火箭发动机首先可拆卸地连接到并插入细长混合室的一端,在另一端具有多级膨胀喷嘴。 然后点火火箭发动机,排气进入混合室,该混合室足够大,以减少从超音速到亚音速的废气速度。 将空气注入到混合室中以与废气中的易燃和/或爆炸产物反应,然后通过多步膨胀喷嘴将所得混合物从混合室排出以膨胀气态混合物,同时, 在气体混合物中产生大大湍流,其比由恒定区域圆形喷嘴产生的湍流水平高大约六倍。 膨胀喷嘴具有具有梯级形状的表面的内壁,其具有不小于2且不大于10的纵横比,以在多步骤喷嘴内产生增加的湍流水平。

    • The present invention relates to an electric valve capable of producing podic mass-flow modulation of a gaseous, liquid, or mixed-phase medium over wide ranges of frequencies, pressure, and flow rates. Such mass-flow modulation can be used to periodically shed large-scale vortices at the outlet and to manipulate their dynamics allowing the user to actively control fluid mixing and transport further downstream. The device has a piezoelectric wafer that in a relaxed state abuts the upstream end of the outlet tube separating the pressurized fluid in the plenum with the outlet. The device has an apparatus for applying electric field to the wafer, which distorts the wafer and ruptures the seal forming a throat area that controls the fluid mass flux. Due to the fast response of the piezoelectric material to an electric field, the throat area can be modulated rapidly in time making the device operable even at high frequencies. The present invention is particularly useful for actively controlling fuel-air mixing in a combustor. However, it may be utilized in other applications such as in medical drug administration for inhalation therapy.
    • 本发明涉及一种能够在宽范围的频率,压力和流速下对气态,液体或混合相介质进行周期性质量流量调制的电动阀。 这种质量流量调制可用于周期性地在出口处流出大尺度的涡流并操纵其动力学,从而允许使用者主动地控制下游的流体混合和输送。 该装置具有处于松弛状态的压电晶片,该压电晶片与出口管的上游端相邻,以将出气口中的加压流体分开。 该装置具有向晶片施加电场的装置,其使晶片扭曲并破裂形成控制流体质量通量的喉部区域的密封。 由于压电材料对电场的快速响应,喉部区域可以在时间上快速调制,使得器件即使在高频也可操作。 本发明对于主动地控制燃烧器中的燃料 - 空气混合特别有用。 然而,它可以用于其它应用,例如用于吸入治疗的药物治疗。
