Abstract

Title: METHOD AND SYSTEM FOR DECELERATING AND REDIRECTING AN AIRBORNE PLATFORM (57) : The present invention provides a method for decelerat- 10 ing and redirecting an airborne platform, comprising the steps of retain- ing a flexible airfoil in non-deployed form in controllably releasable se- cured relation with each corresponding rotor arm of a multi-rotor drone; and upon detecting rate of descent of said drone in a first direction to 4b be greater than a predetermined value, triggering release of one or more of said retained airfoils from said corresponding rotor arm and causing each of said released airfoils to be circumferentially displaced from a first rotor arm to a second rotor arm of said drone to occlude an adja- cent inter-arm region, wherein each of said circumferentially displaced airfoils generates a sufficient value of localized lift that causes said de- scending drone to change its direction of descent from said first direction to a second direction.
