Publication number: 20160151965Abstract: A method of coupling components utilizing electromagnetic energy is disclosed. The method can include obtaining a first component having a first coupling portion, and obtaining a second component having a second coupling portion configured to interface with the first coupling portion. The method can also include disposing a hot melt adhesive on at least one of the first and second coupling portions, and disposing a susceptor proximate the hot melt adhesive. The method can further include mating the first and second coupling portions. In addition, the method can include applying electromagnetic energy to the susceptor. The susceptor can convert the electromagnetic energy to heat, which melts the hot melt adhesive into contact with the first and second coupling portions to couple the first and second components to one another upon solidification of the hot melt adhesive.Type: ApplicationFiled: December 1, 2014Publication date: June 2, 2016Inventors: Curtis B.

Patent number: 9174713Abstract: An unmanned underwater vehicle (UUV) is disclosed. The UUV includes a body and a propulsion system for propelling and orienting the UUV. The propulsion system has an inlet formed in the body that facilitates fluid being drawn into the UUV from outside the body. The propulsion system also has a duct in fluid communication with the inlet. The duct is adapted to direct the fluid along a flow path. The propulsion system further includes a pump operable with the duct to increase the velocity of the fluid. In addition, the propulsion system includes a nozzle in fluid communication with the duct to receive the fluid at the increased velocity. The nozzle is supported about a side of the body and adapted to moveably redirect fluid out of the UUV. The propulsion system provides multi-axis control of the UUV.Type: GrantFiled: November 2, 2012Date of Patent: November 3, 2015Assignee: Raytheon CompanyInventors: Erik F. Item, Mark S.
