Testing Nitrous Oxide for Rocket Propulsion

Using Nitrous Oxide in Rocket Propulsion

Nitrous oxide, also known as laughing gas, demonstrates its capabilities beyond automotive racing, proving to be a potent oxidizing agent for effective use in rocket propulsion. Recently, Markus Bindhammer constructed a hybrid rocket engine and, in his latest video, built and tested a highly practical nitrous oxide dispenser. This form of nitrous oxide is widely available as a propellant for whipped cream, sold under the name "cream chargers," which are essentially small cartridges of nitrous oxide that fit into whipped cream dispensers.

Each cartridge contains approximately eight grams of gas, equivalent to four liters at standard temperature and pressure. To use these cartridges, Markus purchased a whipped cream dispenser, disassembled it to obtain the necessary fittings, and then created an aluminum adapter that connected these fittings to a quarter-inch pipe, installing a valve. In a quick test, he mounted a cartridge, connected it to a pipe, ignited a paraffin ignition chamber, and directed a flow of nitrous oxide towards it, causing a significantly more intense and aggressive combustion. Although its potential oxidizing properties are less known in popular culture, the oxidizing potential of nitrous oxide is a decisive factor for its uses among hackers, whether in racing or in the field of rocketry. Markus is no stranger to working with nitrogen oxides, including nitrogen dioxide, which has an even more aggressive oxidizing potential.
