| Abstract |
This paper presents a discrete elastic model and an aerodynamic discrete vortex model
underlying
a system of computer-aided analysis of shape formation, stress-strain state,
and aerodynamical characteristics of parachutes of various initial shapes
(round, square, cross-type) for small subsonic velocities and
different values of the angle of attack. (In what follows,
the initial shape is also referred as the cutting shape or cutting
configuration.) These models are respectively based on
the numerical methods of lumped masses and
discrete vortices in the form of vortex frameworks. The possibilities of
the system are demonstrated by examples. The problems
of shape formation, stress-strain state, and
aerodynamical characteristics are studied for reefed
and unreefed parachutes.
The numerical results are compared with wind-tunnel data. |
