The invention relates to a device (1) for ejecting a parachute, comprising a housing (2) with an ejection opening (3), wherein the housing (2) is suitable for at least partially accommodating the parachute. In order to enable a robust and repeated ejection of the parachute with a low weight of the device (1), according to the invention a movable base (4) is arranged within the housing (2), which base (4) is connected to the housing (2) via at least one spring element, wherein the base (4) can be releasably fixed in place within the housing (2) using a fixing means (5), wherein the device (1) is configured such that if a parachute is arranged within the housing (2), the base (4) is accelerated by the spring element when the fixing means (5) is released, so that the parachute is ejected through the ejection opening (3) by means of the base (4). Furthermore, the invention relates to a method for ejecting a parachute.

The present disclosure relates to a drone including a drone body; a drone body battery provided in the drone body and responsible for supplying power to the drone body; a parachute kit detachably coupled to the drone body and including a parachute therein; a battery detector provided in the parachute kit and responsible for checking the state of the drone body battery; and a parachute controller for controlling the parachute kit depending on the state of the drone body battery detected by the battery detector, and to a parachute kit for drones. According to the present disclosure, the drone is configured so that, when the power of the parachute kit capable of being attached to or detached from the drone and the power of the drone body are cut off, the parachute is unfolded by spring elasticity or compressed air. Therefore, breakage of the drone may be prevented, and damage caused by drone crashes may be minimized.

Provided is a crash detection device, a method of detecting a crash of a flying object, a parachute or paraglider deployment device, and an airbag device that can improve the reliability in terms of safety. A device detecting a crash of a flying object includes a detection part capable of detecting a flying state of the flying object, a calculation section capable of determining whether the flying state of the flying object is abnormal based on data on the flying state of the flying object acquired by the detection part, and an abnormal signal output section capable of outputting an abnormal signal to the outside when the calculation section determines that the flying state of the flying object is abnormal. The calculation section acquires data from the detection part at a sampling frequency of 1 kHz or more, determines whether the data is data indicating that the flying state of the flying object is abnormal or noise that is unnecessary data when the data is equal to or greater than a predetermined threshold value, determines that the flying state of the flying object is abnormal when the data is determined to be the data indicating that the flying state of the flying object is abnormal.
