Rocket Belt

The Rocket Belt is a hydrogen peroxide rocket.



hydrogen peroxide rocket pictures hydrogen peroxide rocket pictures


These are the rocket engines I built for my rocket bike; these rocket engines have 1100 lbs thrust each (2200 hp each)




These are some of the many hydrogen peroxide rockets I have built, At the left is a 80 lb thrust rocket for a satellite, at right is a 100 lb thrust test rocket for a research company



I use the best refractory metals and the most advanced TIG welding process and welding machines. I weld with MIG, TIG, extended head TIG for titanium and TIG inside a inert gas bell.


How they work?

The hydrogen peroxide rocket engines are, in fact steam rockets, but this steam is produced by a violent exothermic reaction of the peroxide. When passed through a catalyst pack, the peroxide decomposes into superheated steam and oxygen. This high pressure steam is expelled supersonically through a DeLaval nozzle, which produces thrust. For each volume of liquid injected at the catalyst, after the reaction you get 5000 times that volume in gas expelled at the nozzle.

The most important part of these rockets is the catalyst pack. Other elements of the system are: a stainless steel pressure tank to hold the peroxide, a pressure tank to store nitrogen to pressurize the peroxide, a pressure regulator, a flow regulator, valves, lines and gauges.

The nitrogen used to pressurize the peroxide tank causes the peroxide to pass through a flow valve and injects it into the injection plate of the rocket. The catalyst is made of many silver screens. During the reaction these screens convert the liquid hydrogen peroxide into very hot steam and oxygen at high pressure. This jet of gas is used to power the vehicle.

This kind of rocket, whether using steam or hot water, is the safest of all the rocket engines. Sometimes considered a “cool rocket,” it does not produce flame, and therefore can be made of stainless steel.

The Hydrogen Peroxide is the same product commonly used as a household antiseptic at 3% concentration, but here used at 80% to 98% strength. I use it at 90% and I produce my own peroxide.

The Hydrogen Peroxide is the only product used in the reaction, this places it in the monopropellant liquid rocket fuel classification.

The Hydrogen Peroxide contrary to many false information I read in the web, is a clear liquid, non volatile, non explosive, non inflammable and non toxic product that looks like water but with a great amount of oxygen, that´s why in many languages it´s name is "oxygenated water", this product has a slight biting odor and a little bit irritating for the eyes, at the contact with the skin and the eyes it produces oxidation burns, so you must always wear rubber gloves and a face mask to cover your eyes.

This product increase it´s stability with concentration. Yes!, the more pure and concentrated it is, the more stable!. 90% hydrogen peroxide must be stored in special 5254 aluminum alloy containers with vented caps in shaded ventilated rooms preferably but the product is safer to store than gasoline!
You must use approved containers for hydrogen peroxide service, this have a special vented cap.

The hydrogen peroxide is unstable only if it is contaminated and decomposes easily with almost any impurity. Heavy metals, some strong alkalis and the permanganates decompose it instantaneously, liberating a great amount of energy in the form of very hot steam and oxygen.

At this strength the hydrogen peroxide is a very strong oxidizer and upon contact with any organic mater it is burns. For instance, if you soak a cotton rag with 90% hydrogen peroxide it burns very quickly. It can react in a hypergolic way if mixed with other chemicals.

For my rocket bike I built the two hydrogen peroxide rocket engines in the top of this page, see the "Space Age Racing" menu for more information.
