Conceptual Study on Docking-Undocking Unmanned Ground-Air Delivery System

by Dr. Inseong Hwang, Senior Research Engineer, Korea Aerospace Research Institute

This presentation describes the concept of unmanned delivery system; short-range autonomous unmanned ground vehicle (droid) which is responsible for the final delivery to the destination, long-range unmanned air vehicle (UAV) which is equipped with the mission delivery module, and docking-undocking technology between the ground and air unmanned vehicles.

When the goods are to be transported using the unmanned vehicles, the unmanned ground vehicle has a limit to the movement due to the topography, etc., and it is difficult to deliver to the final destination for the unmanned air vehicle under complicated conditions such as urban environment. Therefore, in order to build a 24-hour autonomous delivery system using unmanned vehicles from a large logistics center to the final delivery location of urban areas, it is necessary to develop autonomous ground and air vehicles and a docking-undocking technology between unmanned vehicles.

The top level requirements of the unmanned system are delivery module of 30kg, flight range of 50km, flight speed of 100km/h, endurance of 60 minutes, ground operation radius of 3km, operation time of 2 hours, and all electric system. The final goal is to deliver within a total of 1 ~ 2 hours by the 24-hour automatic logistics delivery system that leads to the city hub and the final delivery center from the large logistics center.

To satisfy this requirement, performance analysis of single rotor helicopter, multicopter, tiltrotor, hybrid aircraft, and winged helicopter configuration was carried out. In addition, technology requirement was reviewed for ground and air vehicle development.
