Low altitude parachute system

摘要

An annular ring parachute intended for low altitude deployment with a low rate of descent. This parachute comprises an annular ring parachute canopy having a central vent. Suspension lines are connected at one end to the outer edge of the canopy and at the other end to risers attached to a load-bearing harness. A restraining device is connected to the canopy which slows the opening of the central vent while the canopy inflates during deployment of the parachute. A pilot chute connected to the restraining means is adapted when inflated to apply a force to the restraining means to slow the opneing of the central vent.
