The main application scenario for drones is folding-wing drones, which are the product of the combination of advanced missile technology and drone technology, capable of rapidly reaching the target area and performing single or multiple tasks such as patrol flights, reconnaissance and surveillance, damage assessment, airborne wireless relay and target attack, and are a kind of intelligent munition with distinctive features that can meet the needs of future information-based operations. The signature feature of the folding-wing UAV is that it can fly on standby for long periods of time, and its flight range exceeds that of missiles of the same class.Compared with traditional missiles, the folded-wing UAV increases the depth of reconnaissance/strike, is easy to realize coordinated attacks with multiple munitions, can suppress and monitor a specific area, and is able to respond quickly to time-sensitive targets.
System Components
The folding wing unmanned aerial vehicle system mainly consists of an aircraft platform subsystem, a mission payload subsystem, a combat system, and a ground control subsystem
Main technical specifications of the flight platform
Functional indicators
Drones meet the following functions:
1) Manual control function
In manual control mode, the folding wing drone responds to remote commands from ground operators for flight.
2) Automatic route function
By presetting the flight route through the ground station, the aircraft will be guided by GPS/GLONASS/Beidou/Galileo after takeoff. The folding wing drone will fly along the predetermined route and end at the last coordinate point.
3) Equipped with photoelectric guidance, it can provide terminal guidance.
It can be equipped with an optical guidance head (combining visible light, laser, and infrared guidance) to automatically track and lock targets, achieving the function of folding wing unmanned aerial vehicles (advanced version product configuration).
4) Installing a radio reconnaissance pod and a signal interference pod can be used as a single aircraft mission for reconnaissance and attack integrated unmanned aerial vehicles, or as a multi aircraft cooperative electronic countermeasure mission in conjunction with fire control strikes.

Basic usage flow
The basic combat mission process of the folding wing unmanned aerial vehicle system consists of several parts: launch, climb, breakthrough, search or tracking, and attack
1) After arriving at the combat area, unfold the product and set up the mission. Then, use the ground launch system to launch the folding wing unmanned aerial vehicle;
2) The folding wing drone enters the climbing phase and climbs to cruising altitude;
3) Folding wing drone swarm accelerates breakthrough to target area;
4) After the folding wing drone cluster arrives at the target area, the radio reconnaissance and jamming pods are simultaneously activated to search for targets within the target area;
5) After discovering the target electronic countermeasure interference source, the interference pod sends interference signals to conduct radio interference on local targets;
6) At the same time, high-precision TDOA time difference positioning technology is used for multi machine cooperation to accurately detect the target position. The target position is sent to the ground control station, and the ground segment control station sends attack commands. The folding wing drone cluster carries out suicide or bombing strikes on enemy targets.
