Abstract

The invention provides an unmanned aerial vehicle parachute loading and unfolding method. An unmanned aerial vehicle parachute comprises a main parachute, a guide parachute, a parachute cabin cover and a parachute unfolding mechanism. The main parachute is stacked in the parachute cabin, the parachute cabin cover is opened through the parachute unfolding mechanism, the guide parachute is thrown out and inflated, the main parachute is pulled out under the pulling force of the guide parachute, and parachute opening is completed. A traditional parachute folding mode is changed, the operation ofloading the parachute into a parachute pack is omitted, the additional weight of the parachute is reduced, operation steps are reduced, and the parachute can adapt to more parachute cabins in different forms; an umbrella unfolding mechanism is changed, the operation and use method is simplified, and the reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an umbrella loading and opening method for an unmanned aerial vehicle. Background technique [0002] In recent years, UAV technology has been continuously developed and applied. Higher and higher requirements are put forward for the safety of UAVs. Parachute UAVs have been widely used in the military and civilian fields because they do not rely on airports and have lower requirements for launch and recovery sites. Because the parachute drone itself has a parachute, it can open the parachute and recover according to the instruction after completing the task. In the case of a sudden failure, in most cases, the parachute can also be used to realize the emergency recovery of the drone. , to protect the UAV itself from loss. [0003] Parachute recovery has the advantages of simple structure, low requirement for recovery site, reusability and low cost. A...
