    • A hot gas control system includes a pressure vessel defining a chamber in which is disposed a body of solid propellant material that has a leading portion and a trailing portion. A first layer of the body of solid propellant material extends between the leading portion and an intermediate region of the body of solid propellant material, and a second layer extends between the intermediate region and the trailing portion of the body of solid propellant material. The first layer is composed of a first propellant composition that produces a relatively clean gas, and the second layer is composed of a second propellant composition that produces a relatively less clean gas. The body of solid propellant is arranged to burn within the chamber from the leading portion toward the trailing portion and thereby produce a quantity of gas that passes through an outlet port to a ducting path, the first layer having a thickness sufficient to produce enough relatively clean gas to preheat the ducting structure and thereby inhibit contaminant accumulation due to the withdrawal of heat from the less clean gas.
    • 热气体控制系统包括限定腔室的压力容器,其中设置有具有前部和后部的固体推进剂材料体。 固体推进剂材料体的第一层在固体推进剂材料体的引导部分和中间区域之间延伸,第二层在固体推进剂材料体的中间区域和尾部之间延伸。 第一层由产生相对清洁气体的第一推进剂组合物组成,第二层由产生相对较少清洁气体的第二推进剂组合物组成。 固体推进剂的主体被布置成在腔室内从引导部分向后部燃烧,从而产生一定量的气体,其通过出口到管道路径,第一层具有足以产生足够相对干净的厚度 气体以预热管道结构,从而由于从较不清洁的气体中排出热而抑制污染物积聚。

    • In a guided projectile such as a missile, it is often necessary to negate the lift force imparted by the wings (5) during early low velocity stages of flight. Thus, wings (5) can be flattened against the airframe (2) of the missile (1) by a passive constraint, e.g., a shrink tubing (35) which disintegrates due to aerodynamic heating at a higher velocity stage of the flight, allowing each wing (5) to deploy into a position generally orthogonal to the airframe (2). The deployment force can be provided by torsionally and compressionally preloaded springs (19).

    • In a guided moving warhead (1) which can be a missile or a projectile containing a long rod penetrator (3), alignment wings (5) keep the rod (3) in alignment with the warhead's velocity vector, thus maximizing its destructive potential. Two pairs of wings (5) are coupled to the rod (3) by means of a two-axis gimbal (7). One pair of wings (5) pivots along one axis of the gimbal (7) while another pair pivots about a second orthogonal axis. Aerodynamic forces cause the wings (5) to align with the relative wind, and as a result, the rod (3) aligns with the warhead's velocity vector as desired. Orthogonal components of crossflow acting upon the wings (5) can be compensated out by means of gearing the shafts (11, 15) which connect the wings (5) with the gimbal (7). In the case where warhead (1) is a missile, it is often necessary to negate the lift force imparted by the wings (5) during early low velocity stages of flight. Thus, wings (5) can be flattened against the airframe (2) of the missile (1) by a passive constraint, e.g., a shrink tubing (35) which disintegrates due to aerodynamic heating at a higher velocity stage of the flight, allowing each wing (5) to deploy into a position generally orthogonal to the airframe (2). The deployment force can be provided by torsionally and compressionally preloaded springs (19).
    • 在可以是导弹或包含长杆穿透器(3)的射弹的导向移动弹头(1)中,对准翼(5)保持杆(3)与弹头的速度矢量对准,从而最大化其破坏性潜力。 两对翼(5)通过双轴万向节(7)联接到杆(3)上。 一对翼(5)沿着万向节(7)的一个轴线枢转,而另一对翼绕第二正交轴线枢转。 空气动力使翼(5)与相对风对准,结果,杆(3)根据需要与弹头的速度矢量对准。 作用在翼(5)上的横流的正交分量可以通过齿轮将翼(5)与万向节(7)连接的轴(11,15)进行补偿。 在弹头(1)是导弹的情况下,通常需要在早期的低速飞行阶段期间否定由翼(5)施加的升力。 因此,翼(5)可以通过被动约束(例如,由于在飞行的更高速度阶段的空气动力学加热而分解的收缩管(35))而平坦地抵靠导弹(1)的机身(2),允许 每个翼(5)部署到大致垂直于机身(2)的位置。 部署力可以通过扭转和压缩的预加载弹簧(19)来提供。
