专利汇可以提供Ejector pumping systems专利检索，专利查询，专利分析的服务。并且An ejector pumping system according to this disclosure includes an impeller pump driven by a turbine for pumping monopropellant to a catalyst pack where the monopropellant is decomposed to form exhaust gas. The turbine is driven by exhaust gas from the catalyst pack.，下面是Ejector pumping systems专利的具体信息内容。
1. Apparatus comprising: supply means for supplying propellant; impeller means having an input adapted to receive propellant from said supply means and having an output; catalyst means for receiving the propellant from said output and for decomposing said propellant to form exhaust gases; turbine means adapted to be driven by said exhaust gases from said catalyst, said turbine means being adapted to drive said impeller means so that said impeller means pumps propellant to its output at a pressure higher than at its input; and outlet means for exhausting said exhaust gases at a high velocity.
2. Apparatus according to claim 1 further including second impeller means having an input connected to said supply means and having an output connected to the input of said first-named impeller means, and second turbine means adapted to receive pressurized propellant from the output of said first-named impeller means to drive said second impeller means so that said second impeller means pumps propellant to its output at a higher pressure than the pressure of the supply.
3. Apparatus comprising: supply means for supplying propellant; first impeller means having an input adapted to receive propellant from said supply means and having an output; a second impeller means having an input adapted to receive propellant from said output of said first impeller means and also having an output; catalyst means for receiving propellant from said output of said second impeller means and for decomposing said propellant to form exhaust gases; a first turbine means adapted to be driven by said exhaust gases from said catalyst, said first turbine means being adapted to drive said second impeller means so that second impeller means pumps propellant to its output at a pressure higher than at its input; a second turbine means adapted to receive pressurized propellant from the output of said second impeller means and adapted to drive said first impeller means so that said first impeller means pumps propellant to its output at a higher pressure than the pressure of the supply; and outlet means for exhausting said exhaust gases.
4. Apparatus according to claim 3 wherein the propellant which drives said second turbine means is returned to the input to said second impeller means.
5. Apparatus according to claim 3 further including at least a second catalyst means for receiving propellant from said output of said second impeller means and for decomposing propellant to exhaust gases, and at least a second outlet means for exhausting the exhaust gases from said second catalyst means.
6. An ejector pumping system for pumping secondary fluid comprising: nozzle means so disposed and arranged with relation to the secondary fluid that discharge of primary fluid througH the nozzle means causes the pumping of secondary fluid; supply means for supplying propellant; impeller means having an input adapted to receive propellant from said supply means and having an output; catalyst means for receiving propellant from said output and for decomposing said propellant to form said primary fluid; turbine means adapted to be driven by primary fluid from said catalyst, said turbine means being adapted to drive said impeller means so that said impeller means pumps propellant to its output at a pressure higher than at its input; and outlet means for exhausting said primary fluid to said nozzle means.
7. Apparatus according to claim 6 further including second impeller means having an input connected to said supply means and having an output connected to the input of said first-named impeller means, and second turbine means adapted to receive pressurized propellant from the output of said first-named impeller means to drive said second impeller means so that said second impeller means pumps propellant to its output at a higher pressure than the pressure of the supply.
8. Apparatus according to claim 7 wherein the propellant which drives said second turbine means is returned to the input to said first-named impeller means.
9. Apparatus according to claim 6 further including second catalyst means for receiving propellant from said output and for decomposing propellant to primary fluid, and second nozzle means for exhausting the primary fluid from said second catalyst means to pump said secondary fluid.
10. Apparatus according to claim 5 wherein the propellant is a monopropellant.
