Does hydrogen peroxide work as a rocket fuel oxidizer by itself?
Suppose an aerospace company is building a rocket engine. Their fuel is isopropanol. They don't have access to LOX or another common oxidizer, and the engine cannot be air-breathing. They only have ...

How to calculate combustion temp? [duplicate]
I was reading about a propellant combination using ethanolamine(19.9% propellant fraction w/ 1% Copper Chloride) and 90% HTP(80.1%). I am trying to design a hypothetical engine around the propellant, ...

What is the propellant mass for the Soyuz descent module?
I learned some time ago that the Soyuz capsules use hydrogen peroxide as a monopropellant. I'm trying to use this fact for a chemistry question posed to my students, but I cannot find anywhere how ...

Decomposing HTP through regenerative cooling for use in closed expander cycle
HTP or high test peroxide has a long history as a low cost and high reliability oxidiser, and has had a lot of recent attention for its pseudo hypergolic nature when passed over a catalyst bed. ...

Designing a catalyst for use in catalytically hypergolic fuel mixtures using nitrous oxide
The use of hydrogen peroxide with hydrocarbons such as RP1 has long been a popular choice, not least of all for its hypergolic properties when paired with a catalyst bed. This motor design, catalysing ...

If high-test peroxide is most stable when pure, why are most uses of it in rocketry at lower concentrations?
Per the Wikipedia article for High-test peroxide:
Hydrogen peroxide becomes more stable with higher peroxide content. For example, 98% hydrogen peroxide is more stable than 70% hydrogen peroxide. ...

What is the products of a catalyzed reaction between Hydrogen Peroxide and Ethanolamine with Copper(II) Chloride?
I found this article about Hypergols, specifically H2O2. It mentions in table 3 and in the body of the paper that they found that Ethanolamine with Copper Chloride reacted vigorously. In my search for ...

When has hydrogen peroxide been used in rocketry?
Peroxide is apparently a very good propellant, but I can't seem to find any instance of it being used. Has it ever been used and if not, why hasn't it? What's its downsides?

HTP as oxidizer for main propulsion
Please anyone elaborate why hydrogen peroxide is not used as an oxidizer for main propulsion. I see that everyone agrees on this but from my point of view its a big flaw. I think that industry has ...
