Publication number: 20230008322Abstract: Embodiments are directed to systems and methods for estimating wear in aircraft rotor systems. Data associated with loads and motions of a swashplate actuator is collected. The swashplate actuator drives a swashplate and at least one control link is coupled to the swashplate. The loads and motions of the at least one control link is estimated based upon the loads and motions of the swashplate actuator. Using a wear model, the current wear of control link components is estimated due to the loads and motions of the at least one control link. Wear estimates for the components are aggregated across multiple flights and used to determine when maintenance actions should occur.Type: ApplicationFiled: July 7, 2021Publication date: January 12, 2023Applicant: Bell Textron Inc.Inventors: Brian E.

Publication number: 20230002040Abstract: A torque measurement system determines torque on a shaft by monitoring angular deflection of the shaft under load using phase shift measurements. Calibration of the system uses a defined offset that is determined using a reference operating condition. The offset calibration value is determined for a rotorcraft using the following steps: defining a reference operational condition in which the shaft is rotating, estimating the torque at the reference condition based on aerodynamic knowledge of the rotors coupled to the shaft, operating the shaft at the reference operational condition, capturing sensor data to determine the phase difference at the operational condition, and associating the phase difference and an estimated torque as a calibration value to enable calculation of torque in the torque measurement system.Type: ApplicationFiled: June 30, 2021Publication date: January 5, 2023Applicant: Bell Textron Inc.Inventors: Charles Eric Covington, Brian E.

Patent number: 9156567Abstract: The present application relates to a system and method for providing real-time indications of economic impact of aircraft operations to an aircraft operator. The system and method allow the aircraft operator to reduce economic impact during flight of the aircraft. Such an analysis and cue to the aircraft operator allows the operator to make real-time changes during flight to reduce damage of life-limited aircraft components, thereby reducing the economic impact of aircraft operation that is directly associated with maintenance and component replacement. The system and method can also include pre-flight and post-flight analysis methods for reduction of economic impact of flight operations.Type: GrantFiled: July 23, 2014Date of Patent: October 13, 2015Assignee: Bell Helicopter Textron Inc.Inventors: Charles Eric Covington, Brian E.

Publication number: 20040237984Abstract: A cigarette filter that includes a multiple section filter which reduces the level of predetermined smoke constituents. The filter (130) consists of a fibrous filter plug (132) located at the mouth-end of the cigarette, a section (136) containing a selective adsorbent material, and a section (134) containing a general adsorbent material. The selective adsorbent material, such as a phenol-formaldchyde resin matrix surface-functionalized with mainly primary and secondary amine functional groups, removes specific smoke constituents from the tobacco smoke. The general adsorbent material, such as activated charcoal, is preferably capable of adsorbing a range of chemical compounds without a high degree of specificity. Structurally, the fibrous filter plug, the selective adsorbent section, and the general adsorbent section are co-axially aligned it tandem.Type: ApplicationFiled: January 30, 2004Publication date: December 2, 2004Inventors: James N Figlar, Brian E Tucker, F Kelley St Charles

Patent number: 6598607Abstract: A non-combustible smoking article is provided in which a flavor generating medium, such as a commercially available cigarette, is heated with a fuel element including a liquid fuel therein to generate flavors or other components in vapor or aerosol form. A reusable fuel element is inserted in one end of a tubular member and a flavor generating medium, such as a cigarette, is positioned in the opposite end of the tubular member. Spacing between the fuel element and the cigarette is sufficient so that the cigarette is not lit but hot gases come into contact with tobacco or the like in the cigarette to vaporize the flavor components therein.Type: GrantFiled: October 24, 2001Date of Patent: July 29, 2003Assignee: Brown & Williamson Tobacco CorporationInventors: Kayyani C.
