Application of liquid hydrogen as a fuel for future passenger aircraft

The paper briefly reviews a recent initiative on the application of hydrogen as a fuel for future commercial aircraft. Special attention is paid to the benefits of using liquid hydrogen (LH2) to power aircraft engines. A comparison of LH2 to other fuels is presented, as well as a comparison of LH2 hazard to hazard imposed by typical jet fuel. Major attention is focused on the combustion of hydrogen benefits in turbine engines with classic deflagrative combustion chamber and engines utilizing detonative combustion of the hydrogen-air mixture. Benefits and problems with the utilization of LH2 are discussed in this paper.
