The exemplary embodiments provide a system of selectively moving airplanes on an airport apron. Airplanes are selectively moved from selective parking locations to areas adjacent to take-off locations such as runways. Airplanes may also be selectively moved from an area of the apron adjacent to a landing location and/or to a parking location. This may include for example an unloading location, an airport terminal, a servicing location, a fueling location, storage location and/or other suitable location. The exemplary system includes driving channels through which a carriage is selectively moved. The carriage includes a basket for operatively engaging at least one front wheel of selected airplanes for purposes of transporting such airplanes to and between the desired locations.

A modular landing port for use on a top of a building structure. The modular landing port includes a base portion. One or more landing module extend from the base portion. The one or more landing modules have a first end provide proximate the base portion and a second end spaced from the base portion. Each of the one or more landing modules have a landing/take-off zone proximate the second end and at least one loading/unloading zone proximate the first end. The landing/take-off zone and the at least one loading/unloading zone are configured to receive a vertical take-off and landing aircraft.

The invention discloses a system for reducing ambient noise generated from an acoustic domain, comprising a landing pad comprising a plurality of zones of varied porosity levels over specified sections, and a plurality of perforated channels across the plurality of zones of varied porosity levels, the perforated channels comprising a plurality of aqueous sheets placed at an inlet of the perforated channels and along the perforated channels. Also disclosed is a method of reducing ambient acoustic noise produced by unmanned aerial vehicle (UAV) operations, the method comprising the steps of absorbing acoustic energy produced by the UAV via a plurality of zones of varied porosity levels, present in a UAV landing pad, resulting in reducing sound-pressure transmission-loss of propeller downwash across the plurality of zones of varied porosity.

A system for isolating sound generated by an aircraft utilizing a helipad may include a plurality of acoustic scatterers being disposed adjacent to at least a portion of a perimeter of the helipad. Each of the plurality of acoustic scatterers include channels having an open end and a terminal end. Additionally, each of the plurality of acoustic scatterers has an acoustic monopole response and an acoustic dipole response with a resonant frequency that is substantially similar to one another.
