Rocket-based inverted parachute deployment system
A system to deploy a parachute is disclosed. In various embodiments, a plurality of rockets are attached to a perimeter of the parachute. Each of the rockets is configured to fly initially in a first direction substantially in a direction of deployment of the parachute and to fly subsequently along a trajectory that includes a component that is substantially perpendicular to the direction of deployment and extends radially from a center of the parachute.
Wearable Propulsion Flight Systems Suited To The User Body
The Invention corresponds to a technical equipment used to make an individual fly. For instance, the Invention relates to the gatherings of the propulsion units, that are worn near the user scapulas, to provide thrust that pushes the user forward, while the parachute carry the user off the ground creating an ultralight aircraft, the Inventors have realized that it is possible to design a wearable aircraft that uses propulsion units, suited to the human body, to push the user's body forward, while using a parachute and the user's strength for stable flight.
PAYLOAD LAUNCH APPARATUS AND METHOD
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.
IMAGE CAPTURING SYSTEM FOR SHAPE MEASUREMENT OF STRUCTURE, METHOD OF CAPTURING IMAGE OF STRUCTURE FOR SHAPE MEASUREMENT OF STRUCTURE, ON-BOARD CONTROL DEVICE, REMOTE CONTROL DEVICE, PROGRAM, AND STORAGE MEDIUM
An image capturing system for shape measurement includes: an image capturing device configured to capture an image of a structure; an air vehicle; an on-board control device configured to control the image capturing device and the air vehicle in accordance with an image capturing scenario; and a remote control device configured to create an image capturing scenario and transfer the created image capturing scenario to the on-board control device. The air vehicle autonomously flies to image capturing points sequentially so as to capture images. The captured data is transmitted to the remote control device via a wireless LAN.
Parachute Landing Assistant
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 battery pack is comprised of a power storage means such as alkaline, lithium ion, or other types of battery system. The power switch allows the parachutist to enable or disable the operation of Parachute Landing Assistant. The LED indicator light is comprised of an LED that informs the parachutist as to whether the Parachute Landing Assistant operation is enabled or disabled. The audio jack is comprised of a standard , , or 3/32 mono audio or stereo audio receptacle that accepts the analogous audio plug. The microcontroller controls all the other components of the Parachute Landing Assistant. The ground proximity sensor senses the distance from the ground of the parachutist.
Automatic Mode Control of a Parachutist Navigation System
A method of identifying operational modes experienced by a user during a jump from an aircraft may comprise estimating a user altitude and a user descent rate, based on a set of navigation state data vectors. The method may further comprise determining that the user is ready to transition from a flight mode to a descent mode when the user altitude is above a jump altitude threshold, and a variation of the user altitude is below a predetermined altitude variation threshold. After determining that the user is ready to transition from the flight mode to the descent mode, the method further comprises determining that the user has transitioned from a flight mode to a descent mode when a user ground speed is below a ground speed threshold, and one or both of (i) a GNSS position error estimate, and (ii) the user descent rate estimate, indicates a jump signature.
Inflatable parachute airbag system
A system and method that reduces the descent velocity of an aerial vehicle, the system including a control system, an inflation device, and a deployable, inflatable cage. The control system detects a descent condition, such as an uncontrolled descent and activates the inflation device to inflate the cage to at least partially encase the aerial vehicle and protect the vehicle during descent and landing. The inflatable cage includes a main fill tube, a perimeter tube, and support tubes. The support tubes are connected between the main fill tube and the perimeter tube, and enable gas to flow from the inflation device through the support and perimeter tubes and into the perimeter tube. A drag inducing material enclosure is connected to the inflatable cage and structured to induce drag to reduce a descent speed of the aerial vehicle.
Systems and methods for maneuvering a package following in-flight release from an unmanned aerial vehicle (UAV)
A package delivery system can be implemented to forcefully propel a package from an unmanned aerial vehicle (UAV), while the UAV is in motion. The UAV can apply a force onto the package that alters its descent trajectory from a parabolic path to a vertical descent path. The package delivery system can apply the force onto the package in a number of different ways. For example, pneumatic actuators, electromagnets, spring coils, and parachutes can generate the force that establishes the vertical descent path of the package. Further, the package delivery system can also monitor the package during its vertical descent. The package can be equipped with one or more control surfaces. Instructions can be transmitted from the UAV via an RF module that cause the one or more controls surfaces to alter the vertical descent path of the package to avoid obstructions or to regain a stable orientation.
