Testing and verification of a multicopter design with lifting power 1 ton MTOW

Purpose and goal: Purpose: Verify a design for an all-electric multicopter with a total lift of 1,000 kg. Objective: Verify design and construction Determine material selection Durability- and strength test vital components Ensure design and construction for future production

The objective has been to freeze the design of the supporting structure after this project and transfer it to manufacturing, while the design work can be focused on secondary structure and system design. The goal has been achieved. Expected results and effects:

We have verified the construction. During the strength tests, we discovered certain weaknesses and phenomena that we were subsequently able to deal with, including through redesign. During the tests, we have also identified interesting physical stresses on, for example, the rotor head. We intend to work further with the verified design and produce the first example within the next year.

Approach and implementation: The project started with workshops with invited competences. Based on these workshops, some details of the existing design were revised. Next, a mold was built for the production of the full-size arms. Two full size arms in carbon fiber have been produced. The arm has been tested in strength labs as well as on a mobile platform to simulate effects in flight.

Based on the tests, changes and improvements in the construction have been implemented.
