ABSTRACT:
A parachute of the invention includes a canopy (11), main suspension lines (14) and an auxiliary suspension system (23, 20 and 30). The main suspension system extends between the periphery of the canopy and the load (15) and the auxiliary suspension systems extends between the load (15) and positions (D) and (A) spaced from the periphery of the canopy. The auxiliary suspension system (23, 20, 30) assumes load during the initial stages of deployment leaving the main suspension lines untensioned thereby to allow the canopy skirt to spread without interference. A subsidiary feature of the invention provides for valve members (4) spaced the vent (12) of a canopy (11). Both features result in reduced opening time of the canopy.
