Patent number: 11209345Abstract: A system includes a void filter that receives sensor data employed to produce or inspect a manufactured part, the void filter generates a void data subset indicating voids detected in the manufactured part. A stress analyzer processes the void data subset from the void filter and determines coordinate data and force data for the respective detected voids in the manufactured part. At least one deterministic model analyzes the coordinate data and the force data from the stress analyzer determined for the detected voids from the void data subset. The deterministic model analyzes failure of the detected voids with respect to time and generates deterministic output data indicating failure over a deterministic timeframe. A prognostic analyzer processes the deterministic output data from the at least one deterministic model and generates a failure prediction for the as manufactured part.Type: GrantFiled: May 29, 2019Date of Patent: December 28, 2021Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: John S. Madsen, Jerrell A. Nardiello, Elias L. Anagnostou, John A. Crawford, Stephen J. Engel

Patent number: 10173410Abstract: A process and device for 3D printing parts incorporating long-fiber reinforcements in an advanced composite material is disclosed. A nozzle for a 3D printing device receives a polymer material and a reinforcing fiber through separate inlets. A passage from the reinforcing fiber inlet cleaves the passage containing the polymer material, creating an interstitial cavity into which the reinforcing fiber is introduced. The polymer material closes back on itself and encapsulates the reinforcing fiber, then drags the fiber along with the flow and exits nozzle to be deposited on a work surface or part being manufactured.Type: GrantFiled: December 8, 2015Date of Patent: January 8, 2019Assignee: Northrop Grumman Systems CorporationInventors: Jerrell A.

Patent number: 9962956Abstract: A method and apparatus for embedding critical data directly onboard a physical asset is disclosed. Since the critical data and the asset are never separated, accurate and timely data pertinent to the asset travels with it, and may be written, read, and updated. Accurate data collection ensures a digital model/twin of the asset reflects the true physical state of the asset. Data is embedding optically or magnetically and may be read or rewritten so that information about the life/usage of the asset is continually available, right up to the current state.Type: GrantFiled: November 5, 2015Date of Patent: May 8, 2018Assignee: Northrop Grumman Systems CorporationInventors: Jerrell A.

Patent number: 6484776Abstract: In one form of the present invention, a system for constructing a laminate (122) is disclosed. The system comprises a ply feeder (101) that sequentially stacks one or more plies (100) to form a ply stack (102). A computer (106) directs a laser (104) to cut each ply (100) to a desired shape after becoming part of the ply stack (102). The ply stack (102) is then placed on a reconfigurable tool (112). An applied pressure compresses the ply stack (102) against the reconfigurable tool (112) while an actuator (124) subsequently reconfigures the reconfigurable tool pins (114) to a predetermined shape. In a more particular embodiment, a composites forming process is used, such as diaphragm forming, to compress the ply stack (102) before the reconfigurable tool pins (114) are reconfigured. In another particular embodiment, the reconfigurable tool pins (114) are first reconfigured then a vacuum diaphragm forming process is utilized to compress the ply stack (102) against the reconfigurable tool (112).Type: GrantFiled: April 7, 2000Date of Patent: November 26, 2002Assignee: Northrop Grumman CorporationInventors: Raymond J. Meilunas, Gregory P. Dillon, Jerrell A. Nardiello
