A model-based observer and Kalman filter adjust engine commands in real time to improve thrust and fuel consumption despite wear.
Compressed-air pressure waves let a heat-shielded UAV suppress fires below tree line while maintaining autonomous, precise targeting.
Articulated wingtip nacelles and stacked lift propellers help an M-wing VTOL transition to cruise with less drag, motor weight, and complexity.
Real-time control allocates forces and moments across actuators by tracking geometry changes, saturation limits, and varying effectiveness.
An avionic system segments descent profiles by aerodynamic configuration to generate a vertical path through the aircraft's current state.
