Methodology of the parachute cluster aerodynamic design envisages combined implementation of the reliability computation and continuum mechanics methods. The author developed a software package making it possible to study the influence of total length of the canopy suspension in a bundle, parachutes positioning angle in the system and their number on the aerodynamic characteristics of such systems. The paper analyzes flow features of a number of the parachute clusters assembled from the conventional parachutes with and without canopy ribbing. For the first time, it demonstrates the influence of resonance phenomena in the vortex wake on the parachute bundle stability based on the numerical simulation data. Results of the experimental work with parachute clusters in the wind tunnels in Russia and abroad are analyzed. The paper highlights the canopy features that should be taken into account in constructing parachute cluster systems with various configurations and purposes.
