Abstract: The present disclosure provides a parachute control system for an aircraft which comprises a sensor device, a first control device, a second control device and a drive device. The sensor device is configured for sensing flight states of the aircraft, for converting the flight states to a sensor signal, and for transmitting the sensor signal to the first control device. The first control device is electrically connected to the sensor device for receiving the sensor signal, and is configured for judging whether the aircraft is in a normal flight state based on the sensor signal. If the aircraft is in an abnormal flight state, the first control device is configured to control the parachute to open and to terminate the operation of the aircraft. The present disclosure also provides a parachute control method for an aircraft.

Abstract: Described herein is a vertical take-off and landing aircraft comprising: an upper enclosure comprising a first upper arm and a second upper arm; a lower enclosure comprising a first lower arm and a second lower arm; wherein the first upper arm and the first lower arm comprise a first upper buckle and a first lower buckle, respectively; wherein the second upper arm and the second lower arm comprise a second upper buckle and a second lower buckle, respectively; wherein the first upper buckle engages the first lower buckle and the second upper buckle engages the second lower buckle, thereby securing the upper enclosure to the lower enclosure.
