~ JAXA

»LNG Project
ξ the structure of the tanks is aluminum liner wrapped in Carbon Fiber Reinforced Plastic (CFRP)
ξ CFRP, that strengthens the tank structure, is adhered to the aluminum liner containers that hold the propellant
ξ a launch vehicle is propelled by hot gases spewed from the engine, generated by the combustion of the fuel
ξ unlike jet planes, which utilize atmospheric oxygen for combustion, a launch vehicle must carry its own oxygen supply or other oxidizing reagent in addition to the fuel
ξ the propellant package, including fuel and oxidizing agent, make up the majority of the weight of the launch vehicle
ξ any new developments in the efficiency and design of engine and propulsion technology will have a significant impact on the development of space transportation overall

Hydrogen propellants
ξ consist of liquid oxygen as an oxidizing reagent and liquid hydrogen as the fuel
ξ are used for the world’s best rocket engines, including the LE-5B and LE-7A
ξ this hydrogen-oxygen combination has the advantage of non-toxicity and high performance
ξ it also requires a large tank because of the low density of hydrogen

LNG
ξ use of liquid natural gas (LNG) can reduce the weight, size and cost of the propellant package
ξ JAXA is pursuing research into the use of an LNG propulsion system using LNG and liquid oxygen
