Disclosed is an apparatus for receiving and sending a parcel delivered by a drone, including: a base assembly, configured to be mounted on a building, the base assembly including a platform, in which the platform includes a working surface capable of being horizontally placed; the working surface further includes an operating area for the drone to disengage or engage the parcel; and a barrier assembly, comprising a barrier plate movable with respect to the base assembly, in which in a horizontal state of the working surface, the barrier plate is enabled to be disposed close to an edge of the working surface and between the building and the operating area to separate the operating area from the other side of the barrier plate where the user stays.

A system and method for receiving a package from an unmanned aerial vehicle at a rooftop package receiving station and securely holding the package at the package receiving station. The recipient, using a computing device, may prompt the package receiving station to deliver the package from the rooftop to a delivery location.

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.

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.

Systems for landing and handling of a drone may include a platform on which the drone is supportable in a landed state; a space to receive the platform and drone in the landed state, a first closable barrier arranged between the drone in the landed state and an external environment; a second closable barrier arranged between the drone in the landed state and a passenger zone; and a control arrangement configured to operate the platform, the first closable barrier and the second closable barrier between: a first condition, in which the first closable barrier is in an open condition, the second closable barrier is in a closed condition and the drone is landable on the platform, and a second condition, in which the platform and drone in the landed state are receivable by the space, the first closable barrier is movable to a closed condition, and the second closable barrier is moveable to an open condition.
