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 ...
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 ...
Application of photogrammetry to determination of the propeller geometrycomparision with systematic series
(ABCMRibeirao Preto, 2013-11-03)
The maximum speed requirements for hight speed boats is very important and just one knot less than maximumspeed established can invalidate the design or even the manufactured boat. On the other hand, there is a great ...
Design and characterization of nozzles and solid propellants for IR laser propulsion
(Springer, 2014-06)
In this article, we present an experimental study of the effect of conical section nozzles coupled to solid targets on laser ablation propulsion. The impulse produced on the target by laser ablation was measured in terms ...
An Optimal Blade Design for Mini Wind Generators Mountable on the Spoiler of a Vehicle
(Springer Science and Business Media Deutschland GmbH, 2022-01-01)
In this work, a mini wind turbine was developed that takes advantage of the kinetic energy of the winds around a moving car. The blades were designed according to inclination angles in order to capture as much energy as ...
