Longitudinal wind field detector and prediction method thereof

Abstract

The invention relates to a longitudinal wind field detector and a prediction method thereof, the longitudinal wind field detector comprises a paragliding wing system and a control system, the paragliding wing system comprises a paragliding wing, a control rope, a paragliding rope, a sling and a load control box, the control system realizes GPS positioning, wind field identification and wind field prediction, and real-time display on a ground station is realized. The parachute wing is used as a speed reducer to ensure the flying stability of the parachute wing, so that the speed of the wind field detector based on the deceleration performance of the parachute wing relative to the ground is only related to the wind speed, and the parachute wing has higher stability compared with other deceleration parachutes. A wind field detector is used for detecting a working airspace wind field which changes along with the altitude in an aerial drop mode, tracking longitudinal distribution of the changing wind field in real time, and providing key disturbance data for accurate autonomous homing of a parafoil system. Through actual detection experiments, the down-cast wind field detector can identify and predict the wind field with high precision, and the change trend of the wind field can be tracked in a short time.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a longitudinal wind field detector and a prediction method thereof. Background technique [0002] UAVs have a simple structure and low cost. They can be used not only for military purposes such as small-scale detection and reconnaissance, and delivery of emergency supplies, but also for civil purposes such as aerial photography, spraying pesticides, and port fog removal. Due to its low speed, it is easily affected by atmospheric environmental conditions. In fact, even in today's fairly well-designed aircraft, wind field disturbance is still one of the important reasons for the failure of mission execution. Therefore, before UAVs perform missions, It is necessary to detect the changing wind field in the working airspace, plan a reasonable flight trajectory, and design a corresponding anti-wind disturbance control strategy to ensure the smooth execution...
