Title: OPTIMIZATION OF THE CYCLE OF A TURBOSHAFT AIRCRAFT ENGINE WORKING ON LIQUID HYDROGEN
Keywords: hydrogen fuel, gas turbine, gas turbine cycle simulation

Abstract: Abstract: Nowadays the hydrogen is regarded as one of the possible solutions of the problem of making the civilian aviation carbon neutral. The most efficient form of storing hydrogen onboard, so far is the liquid hydrogen (LH2). Even this type of storage has significant drawbacks in comparison with the hydrocarbon fuels, mainly connected with the low energy density of LH2. One of the ways of minimizing this drawbacks is by using all the possibilities to optimize the power plant of the aircraft for using LH2. Possible hydrogen power plants include fuel cells and gas turbines where gas turbines are regarded as a solution for medium and large aircraft. In this article some optimizations of the LH2 fueled gas turbine cycle are proposed. In this number the use of the LH2 fuel as a inter-coolant for the compressor air and simplification of the combustor chamber, when hotted hydrogen is used. These optimizations are evaluated by simulating them in the GasTurb11 software
