#TITLE OF THE PROJECT:

Electromagnetic Launch System with Switchblade Drone

# PROBLEM:

The Switchblade UAVs in use today tend to use pneumatics for power. It has been limited by its launching speed, cost, and portability. Making use of electromagnetic technology can improve the design. The project aims to develop an electromagnetic launch system which can launch switchblade drone well.

# SOLUTION OVERVIEW:

The project involves the development of an electromagnetic launch system and a switchable drone. The launch system is designed to propel a fixed-wing drone to a relatively high speed, using electromagnetic forces. The drone is equipped with a switchable wing mechanism that allows it to be housed within the launching track during launch and then deployed for flight after exiting the launching system. There are several main steps to finish the project well:

Design and construction of the launch system

Development of the foldable wing mechanism

Integration of subsystems

Testing and validation Overall, the project's success will depend on the effective implementation of these solutions, which will require careful planning, design, and testing to achieve the desired outcome of a functioning electromagnetic launch tube with a switchblade drone.

# SOLUTION COMPONENTS:

The solution will consist of the following components:

Electromagnetic launch system: the system includes multiple sets of acceleration coils, a base to hold the coils, a base with both a guide slot for the horizontal movement of the ejection ram, and a launch cart to hold the drone.

Switchblade drone: the system includes the main body of the drone, a pair of foldable wings, a folding device powered by a torsion spring, and an attachment device for the drone to the ejection ram.

Electrical control system: the system mainly controls the charging and discharging of the coil, the main components are Hall Effect Sensors, N-Channel Power MOSFETs, MOSFET Heatsinks, High Speed Power MOSFET Drivers, Resistors, Momentary Switch.

# CRITERION OF SUCCESS:

The success of the project will be determined by the following criteria:

Portability: Weather the system is small and portable enough to be carried in a suitcase or other boxes.

Speed of the launched plane: The speed of the plane needs to be fast enough so that it can travel enough distance and realize some additional functions.

Safety: The system should not cause danger to the operator or other people around it. Potential dangers are, for example, Mechanical scratches and electric leakage.

Stability: The success rate of launching the plane, and the route of the plane after each launching should be similar.

# DISTRIBUTION OF WORK:

Shuyang Qian (ME): Responsible for designing and constructing the mechanical part of electromagnetic launch system including the guide rails, fixing parts and installation of coils.

Zheng Fang (ECE): Responsible for designing and soldering the circuit for controlling the charging and discharging of the coil.

Xinyu Xia (ME): Responsible for designing and constructing the switchblade drone which can be accelerated by the electromagnetic launch system and whose foldable wings can run well.

Ruike Yan (EE): Responsible for designing the control system for switchblade drone which lets the drone continues to fly after leaving the electromagnetic launch system.
