01Project overview

Designing flight-control logic around a human-carrying safety case.

The GoAero challenge centres on compact, rapidly deployable aircraft that can reach places where roads and runways cannot. For a manned multicopter, control decisions must be made with explicit attention to redundancy, degraded operation and safe test progression.

Redundant propulsion

Eight actuators create additional control-allocation options, but also a larger space of nominal and degraded cases to evaluate.

H

Human mission

Emergency-response scenarios put safety margins, predictable behaviour and verification discipline ahead of spectacle.

02My Contribution

Control allocation and validation for safety-critical flight.

01

Control-allocation development

Developed allocation logic that maps vehicle-level force and moment requests across the octacopter’s actuator set.

02

Simulation validation

Built and evaluated control workflows in MATLAB and the UAV Toolbox before moving toward flight hardware.

03

Mission-oriented control

Contributed robust strategies for emergency-response profiles with attention to stability, performance and safety margins.

04

Flight-test support

Supported the progression from simulation toward Pixhawk-based integration and practical aircraft testing.

03Control & test approach

Build confidence in layers before expanding the envelope.

Model

Represent vehicle dynamics, actuator geometry and achievable force/moment combinations.

Allocate

Distribute control demand across eight propulsors while respecting constraints.

Validate

Exercise nominal and safety-relevant cases in MATLAB UAV Toolbox workflows.

Integrate

Move verified logic toward Pixhawk hardware and controlled flight-test activity.

Safety principleRedundancy is useful only when the controller understands what authority remains. Allocation and degraded-mode thinking therefore belong to the control architecture—not as an afterthought during testing.

05Results

Competition progress backed by a credible technical programme.

HORYZN advanced through the first and second stages of the GoAero Safety Challenge. The control work established simulation-tested allocation and integration workflows for the manned octacopter while the wider team developed Isar Falke as an emergency-response vehicle.
