AI Technical Summary

Technical Problem

The prior art cannot effectively solve the problem of airship failure in soft landing when the airship is damaged and the airship is unable to land softly, resulting in equipment losses and ground safety threats.

Method used

A parachute-based tethered airship recycling device is designed, including an umbrella package assembly. The umbrella package assembly is composed of a bracket, an umbrella package, a parachute, a guide umbrella and an ejection plate. When the pressure drops in the hull, the unlocking mechanism is controlled to unlock it, so that the ejection plate ejects, pull the guide umbrella and the parachute extend the umbrella package, and realize the soft landing of the airship.

Benefits of technology

By setting up a parachute package assembly on the tether rope, the parachute can be opened in time when the bladder is damaged, avoiding high-speed hard landing of the airship and ensuring the safety of equipment and ground personnel.

Abstract

The invention relates to a parachute-based tethered airship recovery device which comprises a parachute pack assembly, the parachute pack assembly comprises a support, the support is connected with a parachute pack, the parachute is arranged in the parachute pack, the parachute is connected with a guide parachute, the guide parachute is connected with an ejection plate, and an unlocking mechanism is connected between the ejection plate and the support. The unlocking mechanism is provided with an unlocking device used for driving the elastic unlocking mechanism to unlock so as to eject the ejection plate, the recovery device further comprises a pressure sensor fixed to the boat body and a controller connected to the support or the ejection plate, the controller is in control connection with the unlocking device, and the controller is in sampling connection with the pressure sensor; the controller detects a threshold pressure value signal in the boat body sampled by the pressure sensor, outputs a control signal to the unlocking device, controls the unlocking mechanism to unlock, enables the ejection plate to eject out, and pulls the guide parachute and the parachute to extend out of the parachute pack. And high-speed hard landing of the airship is avoided, and the safety of equipment and the safety of ground personnel and property are guaranteed.
