Whipped cream hybrid rocket

What a fantastic question! Absolutely it's possible! $N_2O$ is $N_2O$, whether you get it from an 8g whipped cream charger or a massive industrial tank, it oxidises just the same. The valve you'll ...

Hydrocarbon + Nitrous Oxide: Is this a "friendly" alternative propellant system to hydrazine and NTO?

Substances equivalent in hazard to the hydrocarbon are available at any gas station. It's the oxidizer that's an issue. Gaseous nitrous oxide is used as a propellant in some aerosol cans with rather ...

Highest Isp achieved with nitrous oxide as oxidizer

I don't believe any orbital rockets use nitrous oxide as an oxidizer. Zubrin claims it can be used with an ethelyne-ethane fuel blend to produce 320s specific impulse but that seems optimistic. ...

Hydrocarbon + Nitrous Oxide: Is this a "friendly" alternative propellant system to hydrazine and NTO?

Yes. It is the oxidizer of choice of more advanced hobbyist rocket builders, like the Copenhagen Suborbitals. It's not entirely safe, but it's way safer than most alternatives. Its performance is deal-...

Rocket Engine demonstrator fuel choice

Nitrous oxide can be used as monopropellant, producing oxygen and nitrogen in ratios not too distant from atmospheric air (about 36%), and by itself is pretty harmless and easy to obtain as cartridges ...

Rocket Engine demonstrator fuel choice

A few oxidizer options worth looking at: compressed air. Easy to come by, inefficient as it contains so much nitrogen, but that might be an advantage. compressed gaseous oxygen. Is used in welding,...

Is nitrous oxide hypergolic with anything reasonably safe and obtainable?

My advice is to synthesize some Chromyl Chloride from a oxidized salt of Chromium as it is hypergolic with methanol and sulfur. You can also get about a liter of the liquid with just a days work and ...

Is nitrous oxide hypergolic with anything reasonably safe and obtainable?

Most if not all hypergolic fuels are toxic to varying degrees. Hydrazine, mono- methyl hydrazine, and unsymmetrical dimethyl hydrazine are all in this category. Virgin Galactic Space Ship One used ...

Is nitrous oxide hypergolic with anything reasonably safe and obtainable?

This is a mix that apparently could work. "When passed over a warm ruthenium catalyst bed, gaseous nitrous oxide and an ethylene-ethane gaseous blend combust instantly" Supplies could be found ...

Rocket Engine demonstrator fuel choice

Concentrated hydrogen peroxide and ethanol could be a workable combination if you want two liquids. This has a very nice advantage that you can add water to either solution to reduce performance.
