Abstract
Known air intake type rocket engines of the type in which air is condensed and liquefied by employing a propelling agent, loaded on the rocket, as a coolant, and in which the liquefied air is utilized as an oxidizing agent or working fluid, are improved according to the present invention in that air remaining uncondensed is compressed and then condensed and liquefield by employing the liquefied air as a coolant.
Claims20
A liquefied air cycle engine comprising:
- an air intake duct for receiving air;
- condensor means for condensing at least a portion of the air into liquefied air;
- coolant supply means for supplying coolant to said condensor means;
- a mixing chamber;
- spray means for spraying the liquefied air into said mixing chamber;
- pump means for pumping the liquefied air from said condensor means to said spray means;
- compressor means for compressing any unliquefied air remaining in said condensor;
- means for feeding air from said compressor means to said mixing chamber to mix with the liquefied air sprayed into said mixing chamber such that the air from said compressor means becomes liquefied;
- means for feeding air from said mixing chamber;
- and
- combustor means for combusting liquefied air fed from said mixing chamber.
