Exploring the Mechanical, Thermal and Ballistic Effects of Carbon Black on Paraffin-Based Fuels for Hybrid Rocket Motors
Autor: Paula Cristina Gomes Fernandes, Jessica Santos Gomes, Elizabete Yoshie Kawachi, Marcio Yuji Nagamachi, Luiz Fernando de Araujo F Ferrão, Kamila Pereira Cardoso
Publikováno v: Journal of Aerospace Technology and Management, Vol 11, Iss 1 (2020)
Paraffin-based hybrid propellants have been developed due to their high burning rate. However, they have some disadvantages such as inadequate mechanical properties and unstable burning. In this work, paraffin fuel grains with carbon black were evalu

Autor: Jessica de Oliveira Silva, Josiane Ribeiro Campos Silva, Lucas Barros de Oliveira, Marcio Yuji Nagamachi, Luiz Fernando de Araujo Ferrão
Publikováno v: Journal of Aerospace Technology and Management, Vol 11, Iss 1 (2020)
In composite solid propellants, the oxidizer in the form of particles is embedded in a polymeric matrix. In general, these oxidizers consist in inorganic salts that are hygroscopic, chemically incompatible or sensitive to friction or impact, so that

Ballistic Performance of Paraffin-Based Solid Fuels Enhanced by Catalytic Polymer Degradation
Autor: Jessica Santos Gomes, Marcio Yuji Nagamachi, Elizabete Yoshie Kawachi, Kamila Pereira Cardoso, Luiz F. A. Ferrão
Publikováno v: Journal of Propulsion and Power. 35:115-124
Hybrid propellants are of great interest in space propulsion, but their use has been limited due to the low burning rate of their solid fuel. The use of paraffin was a breakthrough, but these grain...

Thermogravimetric Analysis of the Decomposition of a Paraffin Particle/HTPB Fuel Grain for Hybrid Rocket Motors
Autor: Renato F. Nunes, Tiago B. de Araújo, Kamila Pereira Cardoso, Marcio Yuji Nagamachi, Elizabete Yoshie Kawachi
Publikováno v: 53rd AIAA Aerospace Sciences Meeting.
Paraffin has been identified as a promising alternative for use in propellant grains for hybrid rocket motors. Studies have been conducted using grain as fuel paraffin or liquid hidroxylated polybutadiene polymer (HTPB) due to the high thrust generat
