Patent number: 11787570Abstract: A Marman band clamp has multiple parts, such as two halves, that together make up a ring. The halves are joined by diametrically opposed mechanical connections, one of which is a mechanical release separably mechanically coupled ends of the parts (halves). The mechanical release may include an explosive bolt that is used to release the ends of the halves. The mechanical release may capture portions of the release at the ends of the ring halves after severing of the explosive bolt. A nut may be retained by an end of one of the halves by use of a retainer fastener, such as a pin, to prevent the nut from separating from the ring half end when the bolt is severed. This helps retain the pressurized gases between the severed part of the bolt longer, better using the energy from the pressurized gases to reliably separate the ends of the halves.Type: GrantFiled: August 6, 2020Date of Patent: October 17, 2023Assignee: Raytheon CompanyInventors: Billy B. Reed, Jr., Mark J. Kocan
