Abstract: A turret airbag system is provided including a plurality of airbags disposed within the turret to protect an occupant of the turret from injury and/or ejection from the turret. Turret airbags may be configured in padding around a turret access opening, and/or as substantially cylindrical airbags that deploy between the occupant of the turret and a wall or exterior opening of the turret. In some examples, the turret airbag(s) may be integrated with a countermeasure system that deploys explosion countermeasures and activates the turret airbags based on sensor data and multiple thresholds that indicate a collision event, a rollover event and/or an explosion event.

Abstract: An external airbag for an aircraft includes an inflatable bladder having a top portion and a bottom portion, the top portion being generally adjacent to an exterior of the aircraft. A widthwise panel divides the inflatable bladder into a first cylindrical portion and a second cylindrical portion. The widthwise panel acts to restrict outward bulging of the inflatable bladder. An aperture in the widthwise panel may be used for allowing gas communication between the first cylindrical portion and a second cylindrical portion.

Abstract: An explosion countermeasure system is provided including a first sensor device with a plurality of accelerometers configured to detect vertical acceleration of a vehicle; a countermeasure; a safe and arming device configured to impede activation of the countermeasure; and a processor in communication with the first sensor device and the safe and arming device. The processor may be configured to process acceleration signals received from the first sensor device and to make ready the safe and arming device and initiate the countermeasure based on results of processing the acceleration signals. Making ready the safe and arming device may be based on an initial acceleration exceeding a first threshold, and initiating the countermeasure may be based on the initial acceleration exceeding a second threshold and a velocity change exceeding a third threshold.
