Opis:
The paper presents the main activities of the Institute of Aviation (IoA) in the field of chemical rocket propulsion. The relatively "fresh" research and development team performed many useful works within the last 5 years, starting from the strategy and ideas. Nowadays, the Space Technology Department of IoA acts as a member of international consortia realizing space projects, as well as itself working on its own assignments financed by the European Space Agency (ESA) and IoA funds. The important development aspect of rocket propulsion developed at IoA is the use of "green" propellants. These are chemicals, which are relatively safe for the environment and personnel, being a very promising alternative for storable toxic substances, e.g. hydrazine and derivatives, nitrogen tetroxide. R&D activities of STD are based on the use of Rocket Grade Hydrogen Peroxide (RGHP), also known as High Test Peroxide (HTP). This high-performance mono-propellant and oxidizer is regarded by European entities as one of the most promising candidates to replace hydrazine and its derivatives in the future. Due to numerous advantages, hydrogen peroxide is better suited for systems with human interaction that most of other propellant combinations. The paper contains selected results of research on green rocket propulsion performed at IoA, in which 98% hydrogen peroxide was used as oxidizer and monopropellant. Three types of rocket engines: monopropellant, liquid bipropellant and hybrid have been investigated and are still being developed.

Opis:
Highly concentrated hydrogen peroxide solutions have been widely known and used as rocket mono-propellants and oxidisers in the aerospace industry. However, the use of hydrogen peroxide is becoming more and more important in other fields of modern industry – being applicable to novel formulations of base high explosives for use in mining as a kind of industrial “green explosive”. The authors, explain the facts and dispel some of the myths concerning both the medium and the potentially explosive mixtures based on it. The method of preparation and safe handling of 98%+ hydrogen peroxide is briefly presented and advocated by some of the experimental and literature examples. The paper contains both historical and modern approaches to concentrated hydrogen peroxide based mixtures that have been reported as undergoing detonation. The safety concerns, especially those related to their potential explosiveness during preparation, handling or utilisation are analysed as well. New potential applications of hydrogen peroxide based mixtures that can be used as industrial explosives with low NOx emission levels are presented. The potential of the medium as a “green” and easy to handle oxidising compound that may replace ammonium nitrate in a variety of emulsion and blended ANFO-emulsion commercial explosives that currently constitute the majority of explosives used in the mining industry, is underlined.
