AQUASONIC – A Sounding Rocket Based on Hybrid Propulsion

Applied Mechanics and Materials, 2016
The AQUASONIC project is aimed to develop a sounding rocket including a hybrid propulsion system based on the propellant combination nitrous oxide and polyethylene. It takes place in the frame of the STERN (Student Experimental Rockets) programme founded by the German Space Agency (DLR) in order to promote students in the area of launch vehicles.

Nammo hybrid rocket propulsion TRL improvement program

48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012
In 2010, Nammo initiated an ESA-funded hybrid propulsion Technology Readiness Level (TRL) improvement program based on ideas proposed in a study performed for Ariane 5 ME a year before. In a program lasting less than one year, Nammo executed 29 hybrid rocket firing tests using hydrogen peroxide as the oxidizer.

Ballistic and rheological characterization of paraffin-based fuels for hybrid rocket propulsion

47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011
Solid fuels for hybrid rockets were characterized in the framework of a research project aimed to develop a new generation of solid fuels, combining at the same time good ballistic and mechanical properties. A rheological, mechanical and ballistic characterization of paraffin-based hybrid rocket solid fuels was performed, considering pure wax-based ...

Multifunction Sounding Rocket System Development with Advanced Hybrid Propulsion

51st AIAA/SAE/ASEE Joint Propulsion Conference, 2015
Hybrid rocket propulsion is deemed to be advantageous to its solid and liquid counterparts for the safety nature of the designs. With the proposed innovation in this research using dual-vortical-flow (DVF) chambers, hybrid rocket engines can also deliver thrust performance close to that of kerosene liquid engines but with much reduced production cost ...

Innovative Metallized Formulations for Solid or Hybrid Rocket Propulsion

2012
Several metallized solid rocket propellants, of the broad family AP/Metal/HTPB in the ratio 68/18/14, were experimentally analyzed at the Space Propulsion Laboratory of Politecnico di Milano. In general, they feature the same nominal composition, but different metals (micrometric and nanometric Al, B, Mg, and a variety of dual metals) are implemented ...

Thermal Analysis of a Hybrid Rocket Propulsion System for Interplanetary CubeSats

2017
This paper presents results of a thermal analysis performed on a gaseous oxygen/Polymethylmethacrilate hybrid rocket motor for a CubeSat application. This work was focused on deriving temperatures inside the combustion chamber and verifying the selected materials can withstand the high temperatures and stresses.

Experimental Investigation of Solid Fuels for Hybrid Rocket Propulsion

2015
Wax-based fuels, recently proposed for hybrid rocket propulsion applications and nowadays largely investigated, show regression rates higher than those of traditional fuels (e.g. HTPB) but are aected by poor mechanical properties. Several eorts are under investigation in this field, aimed to optimize the balance between high enough regression rate and ...
