Reference Prototypes
The following platforms are representative of the heavy-lift quadcopter configurations we have developed for client programmes. Client names and production volumes are confidential under non-disclosure agreements. These reference designs illustrate the range of payload capacities, endurance profiles, and environmental specifications that we have delivered to production readiness. All three platforms below underwent full rotor wake interaction analysis, downloadwash characterisation, and drag profiling using our in-house OpenFOAM workflow before any tooling was cut.
