    Abstract: An in-flight impact protection system for aircraft. An aircraft having a panel, with a sensor disposed on the aircraft and adapted to transmit a signal and receive a reflection of the signal. A controller coupled to the sensor and adapted to receive the reflection from the sensor to determine whether an object is near the aircraft's panel. An inflation device, which includes a tube member, is coupled to the controller and positioned inside the aircraft, proximate the panel. After determining that the object is near the panel, the controller can activate the inflation device so that the tube member inflates, thereby buttressing at least a portion of the panel. The panel can be a windshield, fuselage member, or other suitable component.

    Abstract: An aircraft airbag inflation system includes an airbag mounted on an external surface of an aircraft. The airbag is configured to inflate in one of multiple stages prior to the aircraft crashing, and each stage is associated with a respective pressure. The system also includes multiple sensors disposed on-board the aircraft and configured to sense aircraft velocities and an aircraft attitude. The system also includes a controller disposed on-board the aircraft and configured to receive multiple signals from the sensors, the multiple signals representing the aircraft velocities and the aircraft attitude sensed by the sensors, determine a crash event for the aircraft based on the received multiple signals, the crash event including an aircraft sink rate, an aircraft attitude at crash time, and an aircraft distance from the impact surface, and determine a stage at which the airbag is to be inflated based on the crash event.
