Cryogenic Energy Sources for the Commercial Aviation

Abstract

As a result of the growth of air transport in the past decades (1960−2018), the sector’s CO₂ emissions increased from 6.8 million tons to 1,034
million tons. The package of measures aimed to achieve ICAO’s global CO₂ reduction goals sets important technological expectations for engine
manufacturers as well. Accordingly, manufacturers and their consortia with university research groups and research institutes are feverishly searching for solutions. These researches also cover the possible application of new operating principles, structural solutions, structural materials, and new alternative fuels. The paper was inspired by the concept of the so called Multi-Fuel Hybrid Engine (MFHE) burning Liquefied Natural Gas (LNG) and kerosene, investigated by Feijia Yin et al. [6], on the other hand, we examined how the use of LNG and LH2 affects the fuel efficiency and expected performance of aircraft engines compared to kerosene.
