  • Patent number: 11136114
    Abstract: A control system has first and second processing modules for controlling retraction and extension of an aircraft landing gear assembly. The processing modules operate independently providing redundancy. Each processing module is configured to perform a first sequence of steps for retracting the landing gear assembly and a second sequence of steps for extending the landing gear assembly. A step of switching control from one processing module to the other (e.g. an avionics side changeover step) is performed (a) as part of the first sequence of steps, but only after the landing gear assembly has been retracted, or (b) as part of the second sequence of steps. By ensuring that the step of switching control is performed at such times, and not for example between initiation of the first sequence of steps and the retraction of the landing gear assembly, the landing gear assembly may be retracted sooner after such initiation.

  • Publication number: 20150034342
    Abstract: An automated fire protection system for a freighter such as an aircraft may include a single fire retardant source for a first deck and a second deck. The system may further include a plurality of sensors for detecting fire and a plurality of nozzles for dispersing the retardant, wherein each nozzle is paired with one of the plurality of sensors. Once a fire is detected by one of the sensors, the fire protection system may eject fire retardant through only one or more nozzles paired with the sensor that detected the fire. Because retardant may be accurately dispersed close to the detected fire location through less than the plurality of nozzles, an amount of on-board retardant may be decreased, thereby decreasing weight of the fire suppression system. In an embodiment, the fire retardant may only be discharged during the descent, further decreasing the weight of the fire system.
