ABSTRACT:
A parachute comprises a canopy having front and rear sections and a base with shroud lines attached to the base at circumferentially spaced-apart locations therearound. A plurality of brake flaps are disposed below the canopy base and between the shroud lines at the canopy rear section and are selectively adjustable between an inactive position wherein the brake flaps are fully slackened and interfere minimally with the inherent flight characteristic of the parachute and an active position wherein the brake flaps are fully extended and effectively brake the forward velocity of the parachute to thereby increase the parachute angle of descent. A set of control lines attached to the brake flaps selectively and adjustably effect actuation thereof between the active and inactive positions to accordingly control the parachute angle of descent.
