Kind Code:
A
Abstract:
This invention relates to a parachute of the ram air canopy type wherein a canopy is made from a skin formed into a series of elongated, inflatable parallel cells disposed in side-by-side relation to constitute an airfoil when inflated. The inventive concept of the application is the formation of openings in the top and in the bottom wall of each of the cells to form an air passage. These air passages in the bottom and in the top walls of the cells are of greatest capacity in the two outside cells and become of progressively smaller capacity towards the centre of the airfoil. Adjacent cells in the airfoil are in communication with each other through a port in their common wall. The combinaion of passages in the top and the bottom wall of each cell as aforesaid and the port between adjacent cells greatly improves the stability of the parachute, especially under conditions of vertical descent.
