Monopropellant
Monopropellants are propellants consisting of chemicals that do not require an oxidizer to release their stored chemical energy. While stable under defined storage conditions, they decompose very rapidly under certain other conditions to produce a large volume of energetic (hot) gases for the performance of mechanical work. Although solid deflagrantssuch as nitrocellulose, the most commonly used propellant in firearms, and ammonium perchlorate/aluminum/synthetic rubber, widely used in military and spacecraft boosters, could be thought of as monopropellants, the term is usually reserved for liquids in engineering literature. Monopropellants release their energy through exothermic chemical decomposition. The molecular bond energy of the monopellant is released usually through use of a catalyst. This can be contrasted with bipropellants that release energy through the chemical reaction between an oxidizer and a fuel. [1]
Hybrid Engine
A Hybrid engine was designed, manufactured and tested in this laboratory. HTPB polymer and Hydrogen peroxide was used as fuel and oxidizer.
Aluminium Powder
A system for producing Aluminium powder with exactly spherical shape and average 10-50 micron meter diameter was designed, manufactured and tested successfully.
Hydrogen peroxide
Hydrogen peroxide (H2O2) is used as an oxidizer with polymer fuels specially HTPB. High concentrated and pure Hydrogen peroxide was produced in this laboratory.
