Study of the effect of constructive permeability on stability of a parachute with four strips / M. V. Dzhalalova, S. V. Leonov. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2013. № 1. P. 65-68 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 0].
The influence of various structural permeabilities (additional perforation) on the aerodynamic characteristics, shape, and stability of square parachute models with four suspension lines is studied. The parachute is made of a fabric whose air permeability coefficient is equal to zero. The shape of the parachute canopy and the force distribution along the frame ribbons of the canopy are presented.
Key words: parachute, stability, structural permeability, lumped mass method.
