Patent number: 9355541Abstract: A hazardous condition detection system for an enclosure includes at least three detectors and a controller. Each detector is mounted within the enclosure. Each detector is configured to output a signal representing a first lower level of severity (a pre-alarm threshold) and a signal representing a second higher level of severity (an alarm threshold). The controller monitors the operational status of each of the detectors. In a first mode when all the detectors are operational, the controller generates an alarm signal when at least two detectors output a signal at the alarm threshold level. In a second mode when at least one of the at least three detectors are inoperative and at least two of the at least three detectors are operational, the controller generates an alarm signal when one detector outputs a signal at the alarm threshold level and another detector outputs a signal at the pre-alarm threshold level.Type: GrantFiled: March 5, 2015Date of Patent: May 31, 2016Assignee: The Boeing CompanyInventor: Daniel F. Lewinski

Patent number: 8540421Abstract: Systems for analyzing effects of cargo fire on primary aircraft structure are provided. A particular system includes a processor and a memory accessible to the processor. The memory includes instructions executable by the processor to access a thermal profile of a suppressed fire in a physical model of a cargo compartment of an aircraft. The instructions are also executable to analyze heat transfer resulting from applying the thermal profile of the suppressed fire to a structure of the aircraft surrounding the cargo compartment to determine a predicted temperature reached by one or more parts of the structure surrounding the cargo compartment as a result of the suppressed fire. The instructions are also executable to generate an output including the predicted temperature reached by the one or more parts of the structure surrounding the cargo compartment.Type: GrantFiled: December 18, 2009Date of Patent: September 24, 2013Assignee: The Boeing CompanyInventors: Mark F. Ahlers, Mel Eshghi, Daniel F. Lewinski, Richard J. Mazzone

Patent number: 7690837Abstract: Embodiments provide systems and methods for analyzing effects of cargo fire on primary aircraft structure. A thermal profile of a suppressed fire in a cargo compartment of an aircraft is developed. The thermal profile is applied to a heat transfer model of structure of an aircraft, and structural integrity of the modeled structure is analyzed. The thermal profile may be developed by introducing a fire in a physical model of a cargo compartment instrumented with temperature sensors and determining profiles of temperature versus time. A heat transfer model of aircraft structure is built, boundary conditions are input into the heat transfer model, and the model is run. When analysis of the modeled structure determined structural integrity to be insufficient to satisfy flight certification requirements, structural parameters are modified, the thermal profile is applied to a heat transfer model of the modified structure, and the analysis is repeated.Type: GrantFiled: March 7, 2006Date of Patent: April 6, 2010Assignee: The Boeing CompanyInventors: Mark F.
