Abstract

A bulkhead assembly for use with an inflatable modular structure is claimed. The assembly is comprised of a plate, at least one longeron sleeve for receiving and securing the longeron in place, a first and second bladder flange and bladder seals for use in securing an one end of an inflatable bladder to the plate, a number of longitudinal restraint fittings disposed on the plate for securing the loops of a restraint layer such hat the restraint layer substantially encompasses the inflatable bladder.

Independent Claims | See all claims (20)

  1. 1. A bulkhead assembly for use with an inflatable modular structure, the inflatable modular structure having at least two longerons, an inflatable bladder having an opening on opposing ends, and a flexible restraint layer having an opening on opposing ends and a plurality of attachment loops on each end, the bulkhead assembly comprising: a plate having an inner surface; a plurality of longitudinal restraint fittings; a first bladder flange; a second bladder flange; a plurality of flange seals; at least two longeron sleeves; each longeron sleeve being fixedly secured to the inner surface of the plate and adapted to securedly receive a longeron; the first and second bladder flanges being adapted to securedly receive one of the opposing ends of the inflatable bladder therebetween; the second bladder flange being secured to the inner surface of the plate with the plurality of flange seals secured between the plate and second bladder flange; and the plurality of longitudinal restraint fittings being secured to the plate and each of the longitudinal restraint fittings adapted to receive an attachment loop from one of the opposing ends of the flexible restraint layer such that the restraint layer substantially encompasses the inflatable bladder.
  2. 8. A bulkhead assembly for use with an inflatable modular structure, the inflatable modular structure having at least two longerons, an inflatable bladder having an opening on opposing ends, and a flexible restraint layer having an opening on opposing ends and a plurality of attachment loops on each end, the bulkhead assembly comprising: a plate; means for securing the longerons to the plate; means for securing one of the opposing ends of the inflatable bladder to the plate; and means for securing the attachment loops on one of the opposing ends of the flexible restraint layer to the plate.
  3. 9. A method for attaching a bulkhead assembly to an inflatable modular structure, the inflatable modular structure having at least two longerons, an inflatable bladder having an opening on opposing ends, and a flexible restraint layer having an opening on opposing ends and a plurality of attachment loops on each end, the method of attaching the bulkhead assembly comprising the steps of: securing the longerons to the bulkhead assembly; securing one opposing end of the inflatable bladder to the bulkhead assembly; and securing the attachment loops on one of the opposing ends of the flexible restraint layer to the bulkhead assembly.
  4. 19. A longitudinal restraint fitting being substantially “U” shaped defining opposing posts and the posts being adapted to receive a pin and each longitudinal restraint fitting further comprising a roller adapted to receive a pin and the roller being disposed between the opposing posts and the pin cooperating with the posts and the roller such that the roller is rotatable.
