Noise Reduction Installations TRIZ Cases
- Prefabricated Noise Abatement Wall Assembly for Mechanical Equipment
Factory-built wall panels with sound-insulating shells cut on-site work by attaching around stationary mechanical equipment without separate foundations.
- Vertiport Airflow Chamber Layout for Stable, Quieter eVTOL Landings
Through-openings, a suction chamber, and acoustic resonators redirect rotor downwash to curb fountaining and noise during landing and takeoff.
- UAV Flight Route Selection Using Historical Noise Exposure
Historical noise maps guide UAV route planning to avoid repeatedly exposed areas while maintaining frequent low-altitude missions.
- Water-Cooled Flue Gas Collection for Flexible Rocket Testing
A movable wake-treatment structure uses water cooling and modular gas collection for different rocket sizes during testing.
- Curved Porous Jet Deflecting Barriers for Lower Structural Stress
Grooves, reliefs, and through-holes dissipate jet energy, reducing structural stress while maintaining effective upward airflow deflection.
- Total Air Temperature Sensor Strut Turbulence Inducing Surface
A total air temperature sensor strut features a turbulence inducing surface that trips the fluid boundary layer to transition from laminar to turbulent flow.
