High-test peroxide (HTP) is a highly concentrated (85 to 98%) solution of hydrogen peroxide, with the remainder consisting predominantly of water. In contact with a catalyst, it decomposes into a high-temperature mixture of steam and oxygen, with no remaining liquid water. It was used as a propellant of HTP rockets and torpedoes, and has been used for high-performance vernier engines. WebThe density of Hydrogen is 70 g/L. In contrast, the density of Methane is 422 g/L. As a result, a Hydrogen rocket’s fuel tank needs to be significantly bigger than a Methane powered rocket. A big tank means a heavier rocket. Therefore, a Methane powered rocket would be lighter compared to a Hydrogen rocket. Hydrogen is the smallest molecule ...

It would seem to me that, for full-scale rockets, using a fuel which is not liquid at room temperature and pressure is an unnecessary complication. Yes, LOX is used as an oxidizer, but that's because there's no other choice (and LOX is not terribly dangerous to handle unpressurized). I don't doubt that hobbyists somewhere ...

WebA modern solid fuel rocket has a specific impulse of up to approximately 2500 N s kg -1 whilst a good liquid fuel rocket can produce up to 4500 N s kg -1. It is common practice to take a shortcut in the units, at ground level one kg of propellant weighs a little under 10 N and these two figures are cancelled out. WebBulk Density is the density of the combined Fuel and Oxidizer load in their appropriate ratios. Even though Methane is "only" 430 kg/m 3 it is burned with 3.5 parts oxygen compared to 2.1 parts for RP-1, hence a CH4 rocket will …
