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.

Aerial vehicle safety apparatus and aerial vehicle

Provided are an ejection device with reduced weight without reducing an ejection speed of an ejected object and a flying object including the ejection device. An ejection deviceincludes a piston member, a cylinderwhich accommodates the piston memberand is provided with a hole portionfor allowing the piston memberto project outward during operation, a push-up memberpushed up in one direction by the piston member, an ejected objectpushed up while being supported by the push-up member, and a gas generatorwhich moves the piston memberin the cylinder, and in the ejection device, the push-up memberhas a support portiondisposed on a distal end side of the piston memberwith a tip of the piston memberin a moving direction of the piston memberset as a reference.

Ejection device and flying body provided with ejection device

An aerial vehicle safety apparatus includes an expandable object and an ejection apparatus. The ejection apparatus includes a container that accommodates the expandable object and has an opening provided on one end side, a moving member provided in the container, the moving member including an emission base carrying the expandable object on a side of the opening, the moving member being movable along an inner wall of the container, and a driver that ejects the expandable object by moving the moving member toward the opening. A space located opposite to the opening when viewed from the emission base and surrounded by the container and the moving member communicates with a space located outside the space through a communication portion.

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.

An aerial vehicle includes an airframe, a canopy capable of adjusting a speed of falling during falling, a brake cord having one end connected to the canopy, a wind-up apparatus provided in the airframe and being capable of winding up the other end of the brake cord, a sensor unit that detects a distance to an external object, and a controller that controls an operation of the wind-up apparatus based on a result of detection by the sensor unit. The wind-up apparatus includes a gas generator as a drive source. The controller has the wind-up apparatus operate to wind up the other end of the brake cord by activating the gas generator when the distance detected by the sensor unit is equal to or smaller than a prescribed value.
