Aeronomie enables simulations for any aircraft configuration through waypoint-based missions by generating a full-vehicle Simulink model from generic or user-created subsystem models. After running a mission, the software interface lists energy consumption and efficiency for each modeled component of the powerplant and logs all signals from the simulation for custom post-processing. In this paper, we use this capability to compare the energy consumption and general performance of a quadcopter using a proportional-integral-derivative (PID) controller and a linear quadratic regulator (LQR) as the vehicle completes two different missions: a 16-kilometer delivery mission and a figure-eight circuit mission.

Aeronomie enables simulations for any aircraft configuration through waypoint-based missions by generating a full-vehicle Simulink model from generic or user-created subsystem models. After running a mission, the software interface lists energy consumption and efficiency for each modeled component of the powerplant and logs all signals from the simulation for custom post-processing. In this paper, we use this capability to compare the energy consumption and general performance of a quadcopter using a proportional-integral-derivative (PID) controller and a linear quadratic regulator (LQR) as the vehicle completes two different missions: a 16-kilometer delivery mission and a figure-eight circuit mission.

\n Drones are projected to alter last-mile delivery, but their short travel range is a concern. This study proposes a drone delivery network design using automated battery swapping machines (ABSMs) to extend ranges. The design minimizes the long-term delivery costs, including ABSM investment, drone ownership, and cost of the delivery time, and locates ABSMs to serve a set of customers. We build a mixed-integer nonlinear program that captures the nonlinear waiting time of drones at ABSMs. To solve the problem, we create an exact solution algorithm that finds the globally optimal solution using a derivative-supported cutting-plane method. To validate the applicability of our program, we conduct a case study on the Chicago Metropolitan area using cost data from leading ABSM manufacturer and geographical data from the planning and operations language for agent-based regional integrated simulation (more commonly known as POLARIS). A sensitivity analysis identifies that ABSM service times and costs are the key parameters impacting the long-term adoption of drone delivery.\n
