There are provided a safety apparatus and an aerial vehicle including the safety apparatus, in which a lid and an opening end of a container are fixed before operation more firmly than a conventional art to be less susceptible to an external environment. A safety apparatus includes a piston member, a cylinder that accommodates the piston member and is provided with a bore through which the piston member protrudes to the outside during operation, a push-up member that is pushed up in one direction by the piston member, an ejected object 16 that is pushed up while being supported by the push-up member, a gas generator that moves the piston member in the cylinder, and a lid 21 including a projection 21a. The projection 21a includes a second through hole 21c, and an engagement mechanism is configured when a pin member 22 is inserted into the second through hole 21c and a first through hole 18a provided in a container 18 to engage an opening end of the container 18 and the projection 21a.

A drogue parachute assembly may comprise a canopy housing and a mortar. The mortar may include an inner mortar tube and an outer mortar tube configured to telescope relative to the inner mortar tube. The canopy housing may be coupled to the outer mortar tube. A guide plate may be configured to contact an interface surface of the canopy housing and pivot the mortar about a pivot joint.

To prevent a parachute from being damaged. A parachute device (4) includes a flying body (43) including a parachute (400), a parachute accommodation section (40) configured to accommodate the parachute, at least one flying body (43) connected to the parachute, an ejection section (41) having a tube shape and configured to hold the flying body and to eject the held flying body, a gas generating device (60) configured to generate gas, and an extrusion member (42) capable of being at least partially inserted into the ejection section, the extrusion member being configured to extrude the flying body from the ejection section due to receiving pressure of the gas generated from the gas generating device.

A drogue bridle separation assembly may comprise a housing and a pyrotechnic fastener. The housing may define a riser channel and a fastener opening. The pyrotechnic fastener may be configured to extend through the fastener opening and the riser channel. The pyrotechnic fastener includes a charge configured to undergo an exothermic reaction in response to an electrical signal.

Provided are an aerial vehicle safety apparatus capable of smoothly and quickly expanding an expandable object such as a parachute at time of expansion with a simple configuration, and a method of accommodating the expandable object in the aerial vehicle safety apparatus.

An aerial vehicle safety apparatus 100 includes a piston member 10, a cylinder 14 that accommodates the piston member 10 and is provided with a hole 13 through which the piston member 10 protrudes outward at time of operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an expandable object 16 that is pushed up while being supported by the push-up member 15, a gas generator 17 as a power source that moves the piston member 10 in the cylinder 14, and a first member 18 and a second member 21 that serve as a cylindrical container that accommodates the piston member 10, the cylinder 14, the push-up member 15, the expandable object 16, and the gas generator 17. The expandable object 16 is stored in the container so as to form a plurality of layers in a radial direction.

A parafoil for operation at high altitudes, in low density air, or at low airspeeds, and methods for opening same. Some versions of the parafoil comprise flexible members connected to the parafoil canopy. When the parafoil canopy is in a stowed configuration, the members are deformed, storing elastic energy. When the canopy is released from its stowed configuration, the members spring back to their undeformed shapes, thereby opening or assisting with opening the canopy. The flexible member may also be attached to a base structure, which is attached to the payload. The members may comprise rods or hollow tubes that can be flexed using a fulcrum near the base structure, or a spacer plate, so that the ends connected to the canopy are restrained by a parachute bag containing the stowed or packed canopy. The parachute bag can be opened prior to or during detachment of the parafoil from the flight vehicle.
