ABSTRACT:
A method for controlling the drag area growth of a parachute canopy during airborne descent with sensors attached to the payload for facilitating modification of the schedule of release of a parachute canopy reefing mechanism. A control processor is included that can receive and/or calculate a schedule for disengaging the reefing on the parachute. One or more wireless transmitters at the payload transmit the releasing signal from the payload to the reefing mechanism normally located adjacent the parachute canopy. The control processor can also be configured to receive input information from multiple sensors attached to the payload that monitor parameters such as altitude, position, load force, dynamic pressure, time and others to facilitate instantaneous recalculation of the disreefing schedule responsive to such conditions.
