Publication number: 20220164494Abstract: A method including receiving environmental data, sensor data, and a multi-state model are received for an object. The object includes a first material and a second material that galvanically or chemically interacts with the first material. Each of distinct galvanic or chemical state of the object represents a corresponding different equation applicable to a corresponding specific galvanic or chemical interaction between the first and second materials. A stochastic optimization operation is performed on the multi-state model until convergence on candidate sets of galvanic or chemical material change rates for the distinct galvanic or chemical states of the object. A correlation model is generated for a surrogate parameter for the second physical parameters by correlating the environmental data to the sensor data using the candidate sets of galvanic or chemical material change rates. An aircraft design is generated using the correlation model.Type: ApplicationFiled: August 31, 2021Publication date: May 26, 2022Applicant: The Boeing CompanyInventors: Richard J. Thompson, Kristen S. Williams

Patent number: 10761009Abstract: In one aspect, a material system comprises a metal substrate and a first coating layer disposed on the metal substrate. A first electrode is directly disposed on the first coating layer, and a second electrode is disposed on the metal substrate. In one aspect, a method for determining material performance includes flexing a material system and detecting impedance of the material system with an electrochemical impedance spectrometer. The material system has a metal substrate, a first coating layer disposed on the metal substrate, a first electrode directly disposed on the first coating layer, and a second electrode disposed on the metal substrate.Type: GrantFiled: August 26, 2019Date of Patent: September 1, 2020Assignee: THE BOEING COMPANYInventors: Kristen S. Williams, Sean M. Pennell, Erik D. Sapper, Christina C. Grumbach

Patent number: 10436703Abstract: Aspects described herein generally relate to apparatus and methods for determining operational performance of material systems. Apparatus generally comprise a salt fog chamber having a fixture support having material system flexing components to test corrosion of an aircraft material system. In one aspect, a material performance chamber comprises a salt fog chamber and a jaw configured to flex a material system. Methods for determining corrosion include exposing a material system, such as a panel, to salt fog and flexing the material system at a frequency. In one aspect, a method for determining corrosion includes exposing a material system to a salt fog. The pH of the salt fog is from about 3.0 to about 9.0 and flexing the material system at a frequency from about 0.1 Hz to about 60 Hz.Type: GrantFiled: June 29, 2018Date of Patent: October 8, 2019Assignee: THE BOEING COMPANYInventors: Sean M. Pennell, Erik D. Sapper, Andrew G. Wallburg, Kristen S. Williams
