Original sentence: A potential application for a precooled turbojet is as part of the powerplant for a space launch vehicle, or for a very long range, very high speed aircraft.Another advantage is that the compressor and ducting after the inlet is subject to much lower temperatures, and hence may be made of light alloys.Consequently corrected flow can be maintained constant over a wide range of flight speeds thus maximizing net thrust at high speeds.The fuel typically proposed for precooled jet engines is usually hydrogen, since liquid hydrogen is liquid at deeply cryogenic temperatures, and has a very high total specific heat capacity, including the latent heat of vapourisation, higher than water, over its useful range
Edited sentence: Another advantage is that the compressor and ducting after the inlet is subject to much lower and more consistent temperatures, and hence may be made of light alloys.Consequently sea-level conditions (corrected flow) can be maintained after the precooler over a very wide range of flight speeds, thus maximizing net thrust even at high speeds.Hydrogen vehicle.Hydrogen-cooled turbogenerator.Precoolers have never flown.Reaction Engines SABRE.Reaction Engines Skylon.Rejection of condensed water has been achieved (this prevents ice from blocking the system).The fuel typically proposed for precooled jet engines is usually hydrogen, since hydrogen is liquid at deeply cryogenic temperatures, and over its useful range has a very high total specific heat capacity, including the latent heat of vapourisation, higher than water.The state of the art is that a lab scale precooler has been developed in the UK, and tested successfully under representative conditions
