  • Flexible multi-shock shield
    Patent number: 6899009
    Abstract: Flexible multi-shock shield system and method are disclosed for defending against hypervelocity particles. The flexible multi-shock shield system and method may include a number of flexible bumpers or shield layers spaced apart by one or more resilient support layers, all of which may be encapsulated in a protective cover. Fasteners associated with the protective cover allow the flexible multi-shock shield to be secured to the surface of a structure to be protected.
    Type: Grant
    Filed: June 26, 2001
    Date of Patent: May 31, 2005
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventors: Eric L. Christiansen, Jeanne L. Crews

  • Enhanced whipple shield
    Patent number: 5610363
    Abstract: A hypervelocity impact (HVI) Whipple Shield and a method for shielding a wall from penetration by high velocity particle impacts where the Whipple Shield is comprised of spaced apart inner and outer metal sheets or walls with an intermediate cloth barrier arrangement comprised of ceramic cloth and high strength cloth which are interrelated by ballistic formulae.

  • Hypervelocity impact shield
    Patent number: 5067388
    Abstract: A hypervelocity impact shield 10 and method for protecting a wall structure, such as a spacecraft wall 12, from impact with particles of debris having densities of about 2.7 g/cm.sup.3 and impact velocities up to 16 km/s. The shield comprises a stack of ultra thin sheets 11 of impactor disrupting material supported and arranged by support means 13 in spaced relationship to one another and mounted to cover the wall 12 in a position for intercepting the particles. The sheets 11 are of a number and spacing such that are impacting particle 15 and the resulting particulates of the impacting particle and sheet material are successively impact-shocked to a thermal state of total melt and/or vaporization to a degree as precludes perforation of the wall. The ratio of individual sheet thickness to the theoretical diameter of particles of debris which may be of spherical form is in the range of 0.03 to 0.05.
