Advantages of Hydrogen Peroxide

The hydrogen peroxide, presents some characteristics that return it one very promising choice for use in
propulsive systems, amongst the characteristics desired most important they are:

• Versatile, being able to be used as very monopropellant and as oxidante in systems bipropellant;

• With a bigger density that the majority of propellents, needs a minor volume of reservoir and consequently a lesser mass
of the satellite or launch vehicle;

• Lesser toxic that the too much propellents, the example of the hydrazine or the nitrogen tetroxide;

• Raised reason combustible oxidante, thus minimizing the necessity of bigger amounts of fuel;

• Storable for long periods of time;

• Compatible with materials of low cost, as aluminum and stainless steel;

• Low cost if compared with too much propellents, beyond being produced in Brazil;

We present prices it to follow a comparative degree of some used propellents more and monopropellant, in such a way bipropellant used hydrogen peroxide how much.

Availability and Cost of the Propellent

The hydrogen peroxide is produced currently it Brazil to put companies as Degussa (100.000 tons/year) and
the Peroxides of Brazil (120,000 tons/year), this peroxide is commercialized in concentrations of 35%, 50%, 60% and 70%.

The amount of Ethanol produced currently in Brazil is of 16 million tons per year.
The existence of a great installed industrial park, the security in the handling, low the toxic, low cost the technological domain makes of the mixture hydrogen peroxide ethanol a choice certain stops its use as propellent.

Termochemical performance

The simulation results termochemical in show them that the propellents the peroxide base of hydrogen/ethanol has sufficiently satisfactory performance.

The use of hydrogen peroxide in propulsive systems in such a way for attitude control how much main propulsion has received
sufficiently attention on the part from diverse space programs in Russia, China, USA and Europe.

In systems of control, the development of new added catalysers that in small amounts to the fuel return hypergolic the ignition
with the kerosene or the ethilic alcohol presents an alternative of low cost and greater operational security comparative with the traditional systems of hydrazine, mono tetroxide, methyl hydrazine and of nitrogen.

This alternative becomes especially attractive for Brazil that not yet dispose of infrastructure installed for the operation and handling of traditional, toxic propellents, imported and of difficult manipulation.
