Propellant’s differentiation using FTIR-photoacoustic detection for forensic studies of improvised explosive devices
(2017)
The use of propellant for making improvised explosive devices (IED) is an incipient criminal practice. Propellant can be used as initiator in explosive mixtures along with other components such as coal, ammonium nitrate, ...
Effect of a propeller duct on AUV maneuverability
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
A number of autonomous underwater vehicles, AUV, are equipped with commercial ducted propellers, most of them produced originally for the remote operated vehicle, ROV, industry. However, AUVs and ROVs are supposed to work ...
Projeto de hélices pelo método de Adkins para uma aeronave em escala reduzida
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Mecânica, 2018-12-15)
This work is an applied aerodynamic study, focusing on the development and analysis of propellers, using the Adkins methodology as the main bibliographic source. Two codes have been developed for design and analysis, the ...
Diffusion of plasticizer in a solid propellant based on hydroxyl-terminated polybutadiene

A load cell for grain-propelled ballistic rocket thrust measurement
(2005-12-01)
A 1000-kgf resistive strain-gauge load cell has been developed for quality testing of rocket propellant grain. A 7075-T6 aluminum alloy has been used for the elastic column, in which 8 uniaxial, 120-Ω strain gauges have ...
Self-propelled particles with fluctuating speed and direction of motion in two dimensions
(American Physical Society, 2007-12)
We study general aspects of active motion with fluctuations in the speed and the direction of motion in two dimensions. We consider the case in which fluctuations in the speed are not correlated to fluctuations in the ...
