devices to move forward relative to the centerline 23 of the array 20 such that each led type dihedral forming member forms a substantially straight line across the array causing the array to expand and flatten the hinges of the led type dihedral forming members 20 may be designed to lock into position when they straighten during this phase to ensure that the array maintains its fully expanded configuration during landing testing of dihedrally configured arrays is ongoing initial tests have proven the viability and success of the invention the inventors have built a sub scale model of the array and used it to perform deployment tests and demonstrate the stabilization benefits of a dihedral the sub scale model simulated array porosity and dihedral the array was pulled from a stowed folded state by a single pneumatic rocket attached to the array via a bridle the aft end of the array was tethered to a ground point with an elastic line arrestor tests were conducted with and without the arrestor tether in all tests the array deployed and quickly stabilized with no roll or twist and landed correctly tests were also conducted that had the array dihedral oriented upside down those tests in which the array was stowed and deployed upside down very quickly rolled over to the correct orientation before landing the tests on the array undertaken thus far have proven the viability of the invention the inventors are in the process of constructing full scale arrays for flight testing and further fine tuning of the designs in accordance with long standing convention the words 34 a 34 and 34 an 34 when used in conjunction with the transition 34 comprising 34 in the claims denote 34 one or more 34 further modifications and alternative embodiments of.
