Piston Type Power Plants TRIZ Cases

An open power unit and propeller through-space let landing legs sit inside the airframe, improving layout flexibility without propeller interference.

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 clutches and a one-way clutch balance a UAV engine, cancel gyroscopic effects, and enable propeller auto-rotation.

A hybrid UAV power unit uses an isolated engine mount, shaft generator, and balanced battery-tank layout to cut vibration and extend flight time.

Dual variable-speed rotors balance propulsion power and fuel efficiency.

Segmented ducted fans reduce downwash velocity and power requirements while enabling safe urban VTOL operations.

Helical guide converts motor torque to linear motion, automating throttle and propeller controls while reducing pilot workload in piston engines.

Interconnected ECU and EPC controllers coordinate shutdowns of electric motors and heat engines to resolve overtorque, overspeed, and sensor failure risks.

An elastomeric damping sublayer stabilizes the wing against proprotor whirl flutter, enabling higher airspeeds without structural failure.

An opposed piston aircraft engine uses harmonic cams on coaxial shafts to drive pistons in opposite directions within combustion cylinders.

Integrated guides eliminate crane dependency, enabling helicopter deployment of the apparatus onto varying cable trajectories.

Segmented dual-engine rotors distribute propulsion power to lower acoustic emissions while maintaining flight safety during single-unit failures.
