Guiding protrusions direct exchange airflow toward cold lobes, minimizing outlet static pressure and energy losses.
Tilting rotors within semi-wing openings generate lift while reducing noise, resolving wing shielding effects during mode transitions.
Retractable engine intake doors seal off airflow when the engine shuts down, reducing drag and improving fuel efficiency.
Clutch system synchronizes secondary thrust with powerplant via controlled engagement timing, preventing overheating during extended periods.
Clutch arrangements selectively couple axially stacked motor modules to a driveshaft, resolving reliability-complexity contradictions in VTOL propulsion.
A rocket nozzle throat adjusts diameter via temperature-responsive materials to maintain thrust efficiency during propellant depletion.
Segmented thrust augmentation systems distribute fluid streams across distributed thrusters to balance force vectors during vertical take-off and landing operations.
Segmented thrust generators adjust force magnitude and direction independently to counteract external disturbances and restore original position.
A differential speed fan integrated into the aircraft hull reduces drag and noise while maintaining structural integrity.
Cloud-connected balance control manages seat positions and motor power to resolve stability-complexity trade-offs in urban air mobility aircraft.
