Abstract:
Disclosed is a technique for landing a drone using a parachute. The technique includes a parachute deployment system (PDS) that can deploy a parachute installed in a drone and land the drone safely. The parachute may be deployed automatically, e.g., in response to a variety of failures such as a free fall, or manually from a base unit operated by a remote user. For example, the PDS can determine the failure of the drone based on data obtained from an accelerometer, a gyroscope, a magnetometer and a barometer of the drone and automatically deploy the parachute if any failure is determined. In another example, the remote user can "kill" the drone, that is, cut off the power supply to the drone and deploy the parachute by activating an onboard "kill" switch from the base unit.
Abstract:
A fastening system particularly suited for removably securing a first component of a parachute system to a second component. The fastening system includes a first and at least a second magnetic element secured to the first and second components of the parachute system. At least the first magnetic element is adapted to create a magnetic field that attracts the second magnetic element. In the preferred embodiment, both the first and second create magnetic fields which attract each other and may include permanent magnets or temporary magnets. Alternatively, the magnetic elements may include electromagnets connected to a power source. Optionally, a power controller adjusts the strength of the magnetic force generated by the magnetic elements.

Abstract:
An aircraft emergency parachute deployment system (AEPDS) is disclosed. The AEPDS includes a parachute assembly coupled with an aircraft, a ballistic rocket assembly coupled to a top portion of the parachute assembly by a lanyard, an actuator for initiating launch of the ballistic rocket; and a control module configured to receive aircraft orientation measurements and controlling launch of the rocket when the spatial orientation the aircraft is within a pre-selected range of values.
Abstract:
A device to orient a riser of a parachute. The device can include a twist body that is includes a slot through which the riser passes. The slot includes a twist to change the orientation of the riser from a relatively high-profile orientation to a relatively low-profile orientation. The device can also include a link to connect the riser to the suspension lines on the canopy.
Abstract:
A safety system for a parachute comprises at least a sensor configured to sense data indicative of the geometrical configuration of a canopy of the parachute, and at least a controller configured to extract data indicative of the geometrical configuration of the canopy from the sensed data, compare at least part of the extracted data with at least a reference configuration representing a normal operation of the parachute, detect a malfunction of the parachute based at least on said comparison, and, if a malfunction has been detected, command at least an actuator of the parachute or of the safety system, for performing a safety action. A safety system for a parachute is configured to trigger a safety action if a malfunction has been detected based on an analysis of data indicative of the geometrical configuration of suspension lines attached to a canopy of the parachute, or based on an analysis of the load of suspension lines.
Abstract:
A trap system is presented for deployment of a reserve parachute. The trap system includes a trap line with a first end coupled to a main parachute and a trap attached to a surface of the container. The trap includes an outer perimeter to removably hold the trap line and an interior to removably hold the reserve bridle. A kit is also presented for converting a parachute container into an improved parachute container to deploy a reserve parachute. The kit includes an attachment to be secured to a surface of the parachute container. The attachment includes a trap line with a first end configured to be coupled to the first end of the RSL lanyard, and a trap secured to a region of the attachment, with an outer perimeter to removably hold a second end of the trap line and an interior to removably hold the reserve bridle.
Abstract:
Wind parameter indication device and method for providing an indication of wind speed and wind direction. The device is deployed along an aerial trajectory toward a ground surface, such as after being ejected from an aircraft in flight. The device includes an anemometer, an altimeter, a compass, a processor and a transmitter. The anemometer obtains local wind speed and local wind direction measurements along the trajectory. The altimeter obtains altitude measurements along the trajectory. The compass obtains direction measurements along the trajectory. The device may further include an accelerometer, for obtaining acceleration measurements along the trajectory. The processor determines a wind speed value and a wind direction value associated with a predetermined altitude of the device. The transmitter transmits the determined wind speed value and wind direction value to a remotely located receiver. The device may further include a stabilizing decelerator to stabilize and decelerate the device along the trajectory.
