The Nimbus EosXi is an Italian unmanned aerial vehicle (UAV) designed for civilian use, developed and manufactured by NIMBUS Srl. [1] [2]

EOS XI is a hybrid airship having a large, gas-filled delta wing which provides both aerostatic and aerodynamic lift, referred to by the manufacturer as a "metaplane". The cabin, tail assembly and propulsion system are suspended below the wing.

Description

Although classified as an aerodyne (an aircraft heavier than air), the additional aerostatic lift allows extremely short take-off and landing (STOL) distances. Unlike conventional aircraft, which use adjustable control surfaces known as ailerons to maneuver in flight, the EosXi wing is a stiff structure with no moving parts. The craft uses only the suspended tail assembly's moveable planes for course and attitude control, relying on the wing's aerostatic lift to enhance stability. The large wing has a low wing loading that contributes to the vehicle's STOL characteristics.

The wing envelope has a multi-layer construction to obtain the required lightness, strength and aerodynamic characteristics. [3] [4] [5] [6]

The EosXi is claimed to have exceptional stability, due to its low centre of gravity, while the moveable tail surfaces are claimed to give high maneuverability. The delta wing is claimed to allow stable flight even when stalled, which in turn allows steep flight slope angles and extremely low velocity flight with STOL capability. [7]

Unmanned aerial vehicle Aircraft without any human pilot or passengers on board

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention.

In 2000 Paolo Brescia and Tommaso Principi established the collective OBR to investigate new ways of contemporary living, creating a design network among Milan, London and New York. After working with Renzo Piano, Paolo and Tommaso have oriented the research of OBR towards the integration artifice-nature, to create sensitive architecture in perpetual change, stimulating the interaction between man and environment. The team of OBR develops its design activity through public-private social programs, promoting – through architecture – the sense of community and the individual identities. Today OBR is group open to different multidisciplinary contributors, cooperating with different universities, such as Accademia di Architettura di Mendrisio, Aalto University, Academy of Architecture of Mumbai and Mimar Sinan Fine Art University. Among the best known works by OBR are the Pythagoras Museum, the New Galleria Sabauda in Turin, the Milanofiori Residential Complex, the Children Hospital in Parma, the Galliera Hospital in Genoa, the Lido of Genoa, the Ex Cinema Roma, the Triennale di Milano Terrace. The under construction projects by OBR include the Lehariya Cluster in Jaipur, the Jafza Traders Market in Dubai and the Multiuse Complex Ahmad Qasir in Teheran. OBR's projects have been featured in Venice Biennale of Architecture, Royal Institute of British Architects in London, Bienal de Arquitetura of Brasilia, MAXXI in Rome and Triennale di Milano. OBR has been awarded with the AR Award for Emerging Architecture at RIBA, the Plusform under 40, the Urbanpromo at the 11° Biennale di Venezia, the honourable mention for the Medaglia d'Oro all'Architettura Italiana, the Europe 40 Under 40 in Madrid, the Leaf Award overall winner in London, the WAN Residential Award, the Building Healthcare Award, the Inarch Award for Italian Architecture and the American Architecture Prize in New York. Since 2004 OBR has been evolving its design parameters according to the environmental and energy certification LEED and since 2009 OBR is partner of the GBC.
