Piston Type Power Plants TRIZ Cases
- Aircraft Power Unit Layout for Integrated Landing Leg Placement
An open power unit and propeller through-space let landing legs sit inside the airframe, improving layout flexibility without propeller interference.
- Flywheel Adapter Assembly for Gyroplane Engine-Gearbox Vibration
A large-diameter flywheel adapter lets a 2-cylinder 4-stroke engine drive a gyroplane gearbox while damping vibration and handling propeller thrust.
- Counter-Rotating UAV Engine Layout for Gyroscopic Balance
Counter-rotating clutches and a one-way clutch balance a UAV engine, cancel gyroscopic effects, and enable propeller auto-rotation.
- UAV Power Unit Mounting Layout for Engine Vibration Isolation
A hybrid UAV power unit uses an isolated engine mount, shaft generator, and balanced battery-tank layout to cut vibration and extend flight time.
- Intermittent-Combustion Aircraft Propulsion with Dual Variable-Speed Rotors
Dual variable-speed rotors balance propulsion power and fuel efficiency.
- Hybrid VTOL Propulsion System with Segmented Ducted Fans
Segmented ducted fans reduce downwash velocity and power requirements while enabling safe urban VTOL operations.
- Aircraft Piston Engine Actuator Automation via Helical Guide
Helical guide converts motor torque to linear motion, automating throttle and propeller controls while reducing pilot workload in piston engines.
