  Satellite reaction wheel

  Wheel assembly in build; rim geometry and balance iteration ongoing with the satellites team.

  Reaction wheel assembly for spacecraft attitude control. Momentum exchange lets the satellite slew without expending propellant, which sets the design problem: concentrate inertia in the rim, hold balance tightly enough that the assembly does not couple vibration into the spacecraft bus at operating speed, and mount it within the primary structure.

  Skills demonstrated

  • Mechanical design
  • Rotor mass distribution
  • Rotational balancing
  • Structural integration
  • 3D printing
  • Laser cutting

  Fly-by-feel UAV control

  Estimation and control approaches developed and under evaluation with a team of five PhD and postdoctoral researchers.

  Fly-by-feel replaces a handful of discrete air-data probes with sensing distributed through the airframe, so aerodynamic state is reported directly rather than inferred. This work covers the control side: real-time state estimation and feedback formulation, alongside synthesis of existing approaches in the literature.

  Skills demonstrated

  • Real-time state estimation
  • Feedback control
  • Distributed sensing
  • MATLAB
  • Embedded systems
  • Literature synthesis

  Composite fatigue testing

  Crack initiation and growth thresholds characterised for Boeing composite coupons tested to failure under cyclic loading.

  Cyclic load testing of Boeing composite coupons at the Structures and Composites Lab. Coupons are instrumented and run to failure; sensor data is processed in MATLAB to map strain and stress response across specimen life, and reported in lab presentations.

  Skills demonstrated

  • Fatigue testing
  • Failure characterisation
  • Strain and stress mapping
  • MATLAB data processing
  • Technical reporting

  Tornado UAV airframe

  Airframe mass reduced 28% with stability and manufacturability constraints held.

  Full UAV airframe developed as a parametric Fusion 360 model, so that component changes propagate through the assembly without breaking fit. Layouts were iterated with generative design against mass, stability and manufacturability; avionics, transmission and control systems are integrated within the design constraints of other subteams.

  Skills demonstrated

  • Parametric CAD (Fusion 360)
  • Generative design
  • Structural layout
  • Design for manufacture
  • Subsystem integration
