Embodiment Construction

[0018] figure 1 Describes the detection principle diagram applied to the UAV aviation electromagnetic system. The implementation steps are as follows: 1) The UAV takes off all-weather; 2) After reaching a fixed height, hover over the detection area; 3) Lower the receiving pod through the retractable system , The electromagnetic detection system starts to work; 4) The pod is retracted by the hoist, and the detection is completed by returning home. This process requires the receiving pod to maintain flight stability when retracted. Therefore, the present invention proposes a receiving pod applied to the time-domain aviation electromagnetic system of a UAV. The design process of the receiving pod is as follows image 3 Shown. The shape design iteration of the drop-shaped pod body 1 is carried out. The optimization goal is the resistance characteristics and flight stability at cruising speed; the circumferential arrangement of the tail 3 meets the requirements of the pod flight sta...

Abstract

A receiving pod applied to an unmanned aerial vehicle's time-domain airborne electromagnetic system includes a pod body, a support rod, an empennage, and a three-component receiving probe. The shape of the pod body is drop-shaped, the support rod is connected to the tail of the pod body, and the tail fin is in a triangular shape. Six tail fins of the same size are symmetrically arranged at the tail of the support rod along the circumference of the support rod, and each tail fin has a The edge is in contact with the support bar, and the tip of each empennage adopts smooth transition measures. The receiving probes are distributed on the top and the left and right sides of the pod body, and the receiving probes located on the left and right sides are symmetrical along the flow direction. The receiving pod of the invention has small space size, light weight, ensures stability and effectively reduces the aerodynamic resistance of the pod.

Description

Technical field [0001] The invention relates to a receiving pod applied to a time domain aviation electromagnetic system of an unmanned aerial vehicle, which is suitable for the object detection volume of the time domain aviation electromagnetic system of a fixed-wing unmanned aerial vehicle. Background technique [0002] The use of unmanned aerial vehicles for all-weather time-domain aviation electromagnetic detection has attracted more and more attention in China. Because it is different from the electromagnetic detection system of general fixed-wing aircraft, it requires different transmitting and receiving devices. The measurement principle is as figure 1 Shown. The basic design requirements of the receiving pod: Under the premise of ensuring the aerodynamic stability of the drone and the receiving pod, the cross-sectional diameter of the pod should be as large as possible to provide enough internal space to install the three-component receiving coil, resolution and coil turn...
