| Abstract |
Elastic and aerodynamic vortex parachute design models are presented.
The elastic model takes into account centrifugal forces and is based
on the concentrated mass method. The aerodynamic model takes into account
permeability of the canopy fabric in accordance with Rakhmatulin's
hypothesis and is based on the ideal incompressible fluid vortex frame method.
These numerical methods and their combination form a foundation
for the creation of the system "Kupol" (Canopy) designed for computer-aided
calculation of the loading and deformation characteristics of parachutes.
This system allows performing calculations for parachutes with various
cutting shapes of a single-shell canopy, for various angles of attack,
for small subsonic velocities. These calculations are based on the quasi-static
approach and take into account the change in the canopy shape. The potentials
of this system are illustrated by solving case problems. The calculated data
are compared with wind-tunnel test data. Particular attention in this study
is given to getting reliable data as regards the distributed aerodynamic
characteristics. |
