    Los metales han formado parte de la evolución de la humanidad desde la antigüedad. Han sido objeto de culto, por escasos y exclusivos, y han sido la clave del desarrollo de armas, para, progresivamente, formar parte de los ...
  • Aeroelastic analysis of parachute deceleration systems with empirical aerodynamics 

    Ortega, Enrique; Flores Le Roux, Roberto Maurice (2019-11-13)
    Article
    Open Access
    A technique for the aeroelastic solution of parachute decelerators is presented in this work. The methodology uses empirical aerodynamics, based on a filling-time inflation model and Ludtke's area law, coupled to two ...
