摘要: An aerial vehicle safety apparatus includes an expandable object, an ejection apparatus, a bag-shaped member, and a gas generator. The expandable object is wound or folded in a non-expanded state and generates at least any of lift and buoyancy in an expanded state. The ejection apparatus is coupled to the expandable object by a coupling member and ejects the non-expanded expandable object into air. The bag-shaped member is provided in the expandable object and wound or folded together with or separately from the non-expanded expandable object, and expands the non-expanded expandable object by at least partially being inflated like a tube. The gas generator is provided in the expandable object and inflates the bag-shaped member by causing gas generated at the time of activation to flow into the bag-shaped member.

摘要: An aerial vehicle safety apparatus includes a safety mechanism, a drive mechanism, an ejection mechanism, and a control mechanism. The safety mechanism is used for securing safety of at least one of an aerial vehicle and an object outside the aerial vehicle. The drive mechanism includes at least one drive unit serving as a drive source of the safety mechanism. The ejection mechanism ejects the drive mechanism together with the safety mechanism. The control mechanism controls operations of the drive mechanism for the drive mechanism to drive the safety mechanism after the ejection mechanism starts ejection of the safety mechanism.

摘要: Provided is a crash detection device, a method of detecting a crash of a flying object, a parachute or paraglider deployment device, and an airbag device that can improve the reliability in terms of safety. A device detecting a crash of a flying object includes a detection part capable of detecting a flying state of the flying object, a calculation section capable of determining whether the flying state of the flying object is abnormal based on data on the flying state of the flying object acquired by the detection part, and an abnormal signal output section capable of outputting an abnormal signal to the outside when the calculation section determines that the flying state of the flying object is abnormal. The calculation section acquires data from the detection part at a sampling frequency of 1 kHz or more, determines whether the data is data indicating that the flying state of the flying object is abnormal or noise that is unnecessary data when the data is equal to or greater than a predetermined threshold value, determines that the flying state of the flying object is abnormal when the data is determined to be the data indicating that the flying state of the flying object is abnormal.
