    • A modular nuclear rocket engine is disclosed. Each module of the engine includes a plurality of relatively small-diameter pressure vessels each containing a plurality of fuel elements forming a nuclear core. The vessels are composed of low absorption cross section material. An individual exhaust nozzle is connected to each core to receive the propellant fluid which is heated by the core. Because each nozzle is relatively small it is formed of a high-temperature refractory material and is of simple structure having no cooling tubes. The modules are secured closely together to form a modular unit or engine of generally right-cylindrical configuration.
    • 公开了一种模块化核火箭发动机。 发动机的每个模块包括多个相对小直径的压力容器,每个压力容器包含形成核心的多个燃料元件。 容器由低吸收截面材料组成。 单个排气喷嘴连接到每个核心以接收由核心加热的推进剂流体。 因为每个喷嘴相对较小,它由高温耐火材料形成,结构简单,没有冷却管。 模块紧密地固定在一起形成大致右圆柱形结构的模块化单元或发动机。
