## 3 Structure and Dynamic Models of Three Space Flexible Webs  
As shown in Figure 2 below, the new space flexible web consists mainly of Kevlar fabric strips, Canopies (green), EFP warheads (red), and the centrally located explosion range sensor (blue). Because of the error of transmission synchronization and the influence of crosswinds on the ground, the hexagonal double-stripe topology is designed to make the new space flexible web fuller in the air and more favorable to interception. The main body of the new space flexible web is knitted with high-strength and high-resilience Kevlar fabric strips and node canopies. At the same time, 31 canopies are arranged radially according to a particular geometric relation on the new space flexible web, and the distance sensor is placed on the new space flexible web central canopies. Canopies numbered 13-30 secure one EFP warhead each. Canopies numbered 1-12 reinforce the outer nodes. The primary role of the canopies inside the mesh is to secure the corresponding components and maintain the noise stability of the new spatial flexible mesh and EFP warhead in flight. In Figure 2 below, the numbers in different colors represent the distribution of canopies in different positions.

In the background of information warfare, combat drones play an essential role in surveillance, fire suppression, and attack missions and are gradually becoming a key force influencing the war's outcome. When a combat UAV strikes, the new type of space flexible web launcher receives the interception signal transmitted by the detection and resolution system. It adjusts the launch pitch and external angle quickly. After ignition and launch, the new space flexible web is pulled from the storage device by six tractors and is rapidly expanded and formed in the air. According to the target characteristics and threat degree of incoming UAVs, the new space flexible web can reach 80% of the maximum area under the temporal and spatial windows between 20 m and 200 m by controlling the amount of propellant and related launch parameters. It is generally believed that the rising concave web posture is fuller under the temporal and spatial windows. When the range sensor is within 100 m of the intercepting target, the EFP combat section fixed on the control detonating parachute will form multiple directed high-energy jets in the air to intercept the combat UAVs in coordination with each other, thus guaranteeing the safety of our high-value economic targets.  
In order to further explore the dynamic behavior of the new space flexible web, finite element simulation is introduced to analyze the process of the traditional rope web and a new type of space flexible web. Based on the above two types of webs, the same topological rope web (referred to as the topological rope web) is added to the new type of web. As a transition comparison web, three types of simulation webs are compared: traditional rope web, topological rope web, and a new space flexible web, as shown in Figure 3 below.

This paper analyzes the dynamic characteristics of the three kinds of flexible webs in the course of launchings, such as the tension change of the rope web, the movement parameter changes of the traction body, the deformation of the rope web, and the motion state of the rope segment element. It discusses the dynamic characteristics of the vertical launch of three kinds of flexible webs. It provides a reference for the next step in analyzing launch parameters and ground verification experiments of the new space flexible web.
