The systems and methods provided herein are directed to a device for tracking a jumper's elevation during a parachute jump. The device includes an active sensor for monitoring a distance to the ground, which is disposed at an angle and transmitted from the jumper's calf to reduce the chance of self-obstruction. The device notifies the jumper in one of several ways when a threshold elevation is reached, and may take additional automated actions at particular elevation thresholds.

An unmanned aerial vehicle may include a fuselage and an anchor structure coupled to the fuselage and including a wing retention structure and a power module retention structure. The unmanned aerial vehicle may also include a wing releasably coupled to the wing retention structure, thereby coupling the wing to the fuselage, and a power module releasably coupled to the power module retention structure, thereby coupling the power module to the fuselage.

A flying apparatus includes a main structure and a rotative wing surface, the rotation of the wing surface allowing stabilizing the apparatus (100). A fuselage hangs from the wing surface around a hanging point, allowing the wing surface and the fuselage be moveable independently with respect to each other and the wing surface is configured as a disc to manoeuvre the apparatus and including one or more elements acting as security and secondary command and control surfaces, orienting the apparatus in desired directions. The main structure and wing surface can overwrap at least partially the the fuselage in order to improve the aerodynamic performance.

The airframe or fuselage and the wing surface are rotatable around any of three rotational axes independently.

The embodiments of the Parachute Landing Assistant are comprised of a battery pack, a power switch, an LED indicator light; an audio jack; a microcontroller; and a ground proximity sensor. The LED indicator light informs the parachutist as to whether operation is enabled or disabled and indicates when the unit is charging. The microcontroller controls the components of the Parachute Landing Assistant. The ground proximity sensor senses the distance from the ground of the parachutist. The ambient pressure sensor allows the unit to determine its height. During a jump the ambient pressure gauge will sense the pressure change and turn on the Parachute Landing Assistant. It will also be used to send a warning to advise the parachutist of upcoming flare tones established by the ground proximity sensor and microcontroller.

A drone is operated by a sky diver. The drone is interfaced to a parachute pack worn by the sky diver. The sky diver has a device (e.g. smartphone, smartwatch) that communicates with the drone to initiate launch/lift and to release the sky diver. In some embodiments, after the sky diver is released, the drone maneuvers around the sky diver to capture pictures/video of the sky diver. In some embodiments, safety features are included to assure the drone has sufficient battery power to achieve a safe jump altitude above ground level and to assure the release is not made until the drone achieves that safe jump altitude.

Apparatus for releasing a payload from an air vehicle (14), the apparatus comprising a generally tubular holding device (10) mounted on, or formed integrally with, said air vehicle, said holding device (10) having an open end facing in a direction substantially opposite to the direction of travel (16) of said air vehicle (14), in use, the apparatus further comprising a container (18) for housing said payload and configured to be at least partially received within said holding device (10), at least one releasable retaining device (20) for releasably retaining said container (18) within said holding device (10), and an actuation device for selectively actuating said at least one releasable retaining device to release said container from said holding device, said container (18) having thereon at least one drag inducing device (22) configured to induce drag in a direction substantially opposite to that of said direction of travel (16) of said air vehicle, in use, so as to act to drag said container (18) from said holding device (10) through said open end.

Aspects described herein relate to an apparatus, system, and method for the airborne launch of inflatable, lighter-than-air devices from aircraft. In some instances, a container comprising a drag parachute and a main parachute assembly may be deployed from an aircraft. Drag forces on the container may cause the drag parachute to be expelled from the container. Drag forces on the drag parachute may cause the main parachute assembly to be expelled from the container. The main parachute assembly may include a canopy with an opening and a release channel connecting the opening with the container. The container may further include a balloon inflation mechanism, which may be used to inflate one or more balloon envelopes. The one or more balloon envelopes, after being inflated, may be configured to be released from the container, traverse the release channel, and exit the main parachute assembly through the opening.
