Abstract

518,997. Parachutes. TINSSONNIER, G. Oct. 4, 1938, No. 28766. Convention date, Oct. 4, 1937. [Class 4] A parachute has a composite surface made up of elements 1 which are impervious and elements 2 which are relatively porous. The elements may be arranged in various manners, and the canopy may be made of porous tissue lined, over certain zones, with impervious material. 'To reduce the opening shock further, the shroud lines connected to the loops 14x in the middle of the impervious sectors 1 may be longer than the others, so that air can escape from under these sectors at the moment of opening.
