摘要： The invention is an airframe which includes a vehicle (12) having a solid propellant rocket engine (14) and a ramjet or scramjet engine (16); a thrust plug (18) extending from an end (20) of the vehicle which directs combustion gases (23 and 64) produced by the solid propellant rocket engine or ramjet/scramjet engine to produce forward thrust; a longitudinal passage (38) extending from the end of the vehicle to an opening (30) forward of the end which receives external air directed by forward movement of the vehicle and in which solid propellant (32) of the solid propellant rocket engine is located, and wherein during rocket operation solid propellant is combusted to produce the combustion gases in the longitudinal passage which are conveyed by the longitudinal passage into contact with the thrust plug and during ramjet/scramjet operation the longitudinal passage is open to flow of external air after operation of the solid propellant rocket engine is completed and which supports mixing and combustion of the air/fuel by the ramjet/scramjet engine to produce combustion gases which are conveyed by the longitudinal passage into contact with the thrust plug.

摘要： A pair of serially connected electrically operated computer controlled gas valves combine with a pressure sensor to output pressure regulated low pressure gas dispensed from a high pressure gas source and define a pressure regulation system of relatively simple construction, great versatility and of heretofore unknown flexibility, well suited to remote control. The computer controlled valve controller selectively operates the valves in any and all of three operational modes, including the familiar Bang-Bang mode in which both valves operate simultaneously, a Bang-Wait mode in which both valves operate simultaneously for a precise time interval and thereafter close while the outlet gas pressure is checked, and a newly defined Burp mode. In the novel Burp mode, the valve closest to the high pressure gas source is first opened and closed to admit and capture a small volume of gas within inter-valve piping. Thereafter only the outlet valve is opened and closed to release that small volume of captured gas. Each small puff of gas captured and released during repetition of the cycle raises the outlet pressure ever so slightly until the desired pressure is sensed, thereby avoiding significant pressure overshoot.
摘要翻译：一对串联连接的电动计算机控制气阀与压力传感器组合以输出从高压气体源分配的压力调节的低压气体，并且定义了相对简单的结构，大的通用性和迄今未知的灵活性的压力调节系统适合遥控。计算机控制的阀门控制器以三种操作模式中的任何一种和全部三种操作模式选择性地操作阀，包括两个阀同时操作的熟悉的Bang-Bang模式，其中两个阀同时操作精确时间间隔的Bang-Wait模式，此后检查出口气体压力时关闭，并重新定义Burp模式。在新颖的Burp模式中，最接近高压气源的阀首先打开和关闭，以允许在阀间管道内捕获少量的气体。此后，仅打开和关闭出口阀以释放该体积小的捕获气体。在重复循环期间捕获和释放的每一个小气泡都会使出口压力稍微升高，直到感测出所需的压力，从而避免了显着的压力过冲。
