This technology is a soundproof port for aircraft that completely encloses the takeoff and landing space. It features a circular soundproof wall erected around a soundproof floor made of acoustic materials, with curved soundproof doors that slide along a top rail to open and close soundproof openings in the wall.
Existing helipad structures are primarily designed to mitigate fire and crash risks, with little focus on maintaining safe distances between aircraft and passengers or reducing the spread of takeoff and landing noise. Even helidecks equipped with evacuation structures fail to fully enclose the landing zone, leaving issues such as collision risks with passengers, noise pollution, and acoustic loads caused by vibrations transmitted to building rooftops.
This technology absorbs takeoff and landing noise by coating the inner surface of the soundproof wall with acoustic material. A control unit manages the soundproof doors: when the floor's vibration sensors detect a landing and the rail's proximity sensors detect a person, the doors open for access and close again before takeoff. A rail locking mechanism and seals between the doors and walls maintain sound insulation. The floor is made of vibration-damping materials like rubber or urethane, the wall diameter is 24–30m, and lighting is installed along the rail. Applicable to UAM vertiports, rooftop helipads, and hospital emergency helipads, it prevents rotor noise from spreading in residential areas and prevents accidents by ensuring doors only open after the aircraft has come to a complete stop.
