  • Structure for storing and unfurling a flexible material | TechLink
    learning more about this patent and related research and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8356774 Status Active Categories Aerospace Flexible and resilient masts are connected by flexible and resilient inner and outer spars and flexible cords radially connect the spars A flexible material is attached to the cords The assembly is wrapped around a rotatable cylindrical drum in the structure s stored configuration Each mast is flexible only about an axis lying parallel to the axis of rotation of the drum and is otherwise rigid Each mast is linear when extended and has a bending stress when deformed into a non linear configuration such as when wrapped around the drum When the structure is in its stored configuration a restraining device opposes the bending stress and another prevents the drum from rotating Upon disengagement of the restraining devices the stored bending strain energy forces the drum to rotate and the masts to extend into the deployed configuration and thereby unfurl the flexible material USPTO url http patft uspto gov netacgi nph Parser patentnumber 8356774 Facebook Twitter Google Plus LinkedIn Main menu Home Licensing Joint R D Technology Summaries

  • Frangible kinetic energy projectile for air defense | TechLink
    shown effective in neutralizing incoming air borne threat munitions such as rockets artillery or mortars for instance without posing a threat in urban environments to harm bystanders on the ground There are also no hazards or expense with this round of cleaning up unexploded ordnance which might have occurred with other types of rounds due to unreliability of self destruct mechanisms Shown herein is a kinetic energy penetrator for air defense that merely self destructs beyond its operational range into fragments that are not lethal to personnel on ground no pyrotechnic or energetic materials means are used to activate this self destruct process A full bore projectile structure is shown that is composed of plural axi symmetric circular disks stacked on each other and tied by a shape memory metal wire of Nitinol While operational as a joined group the disks are a formidable round to kill an incoming air target After the self destruct phase however each disk is separated from adjacent disks on either side by a spring mechanism that enables separation after the process is initiated in flight when the Nitinol wire deforms due to heating from air drag Each disk then proceeds alone with low enough
