A novel combined engine for a single-stage spacecraft is provided that combines a air-breathing engine utilizing oxygen in the atmosphere as oxidizer and rocket engines for obtaining thrust outside the atmosphere and that does not require a portion whose shape is variable in accordance with the flight speed. Rocket engines 15 are provided on struts 12 that form air introduction channels 10 in the air intake section 4. The rocket jets 18 from the rocket engines 15 control the flow of the airflows 16 introduced into the combustion chamber 20 in accordance with the flight speed. When the spacecraft 1 is stationary or in subsonic flight, the rocket jets 18 promote air intake into the combustion chamber 20 by lowering of static pressure due to expansion (ejector effect). In the subsonic flight condition, it performs the role of air compression, mixing with incoming air, fuel injection and ignition and during supersonic/ultra-supersonic flight it performs the role of a variable diffuser.

摘要:
A system wherein raw material excavated from a plurality of pit faces on a mine are conveyed to and collected at a specific collecting location at the foot of a mountain by a plurality of vehicles and the degree of quality of collected raw material is then properly controlled at the specific collecting location is generally called a mining site control process. To practically execute such a mining control process, the degree of quality of conveyed raw material previously analyzed per each pit face and a quantity of conveyance thereof are confirmed at every time when the raw material is conveyed to the collecting location. Then, the degree of quality of raw material required to be next conveyed so as to allow the degree of quality predetermined as a target with respect to raw material to be collected is determined on the basis of the confirmed degree of quality and quantity of conveyance, and the manner of operating the respective vehicles is determined on a real time base so as to allow the thus determined degree of quality to be realized. When such a manner of operating the vehicles is to be determined, the most effective arrangement is selected for them in view of the representative state of actual operations of the vehicles and their loading capacity. All information in relation to such a mining site control process are electrically processed using a variety of sensors arranged at the respective pit faces and the collecting location, a computer installed in a control center and the like means.
