History

More than two decades of lighter-than-air history.

  1. 2003

    Award-winning Special Shape balloons in Albuquerque, New Mexico, USA

    Engineer Christian Lima do Amaral conceives, designs and supervises the construction and flight testing of the “Little Bees”, special shape balloons 31.4 m tall with a volume of 2,800 m³, designed and built in 100 days. They win first place in the “Best Design” category at the 2003 Albuquerque International Balloon Fiesta, among 750 balloons from 21 countries.

  2. 2011

    Omega AeroSystems is registered

    The company is registered in the state of Paraná, Brazil, with experimental research and technological development as its main activity, at the request of CENPES – Petrobras Research Center, for the analysis and initial study of long-endurance, long-range lighter-than-air solutions for the oil industry.

  3. 2014

    Start of the DirBot 40 DRONI “Noamay” project

    Coordinated by CTI Renato Archer and funded by CNPq (Brazil’s National Council for Scientific and Technological Development) from 2014 to 2017, the Robotic Airship of Innovative Design for Environmental Monitoring in the Amazon brings together universities, research institutes and Omega. “Noamay” means “Guardian” in the indigenous language.

  4. 2018

    First flight of the DirBot 40 DRONI “Noamay” airship

    On 3 March, the airship designed and built by Omega makes its first flight, remotely controlled, in Balsa Nova (Paraná, Brazil), and is featured in Pesquisa FAPESP magazine in May.

  5. 2020

    International scientific publication

    The system architecture is published in the paper “System Architecture of a Robotics Airship”, in the Proceedings of IDEAS 2019 (Springer), with Christian Amaral among the co-authors.

    Partner in LTAAC

    Omega brings its experience in lighter-than-air aircraft to LTA AeroSystems Canada Inc., a joint venture with C.A.R.T.

Noamay · Technology proven in flight

Four thrusters with three-dimensional vectoring.

The DirBot 40 DRONI “Noamay”, an unmanned airship designed and built by Omega, has four high-power electric motors that can be vectored through more than 180° in a coordinated way. This allows it to take off and land vertically, hover and manoeuvre at low speeds.

“This new system, which we call multidimensional vectoring, allows the aircraft to be controlled more precisely along its three axes, which makes hovering easier even in crosswinds.”

Research ecosystem

Developed in a network with top-tier institutions.

Omega was the company that designed and built the aircraft as part of a multi-institutional project. Research with Noamay continued under the INCT (National Institute of Science and Technology) for Cooperative Autonomous Systems (InSAC).

Institutions taking part in the project

  • CTIRenato Archer Information Technology Center: coordination
  • ITAAeronautics Institute of Technology
  • UnicampUniversity of Campinas: automatic control and guidance
  • UFAMFederal University of Amazonas
  • IDSMMamirauá Institute for Sustainable Development
  • ISTInstituto Superior Técnico, Lisbon, Portugal

Leadership

Christian Lima do Amaral

President · Mechanical and aeronautical engineer, University of São Paulo (USP)

Christian leads Omega AeroSystems and brings together experience in the Design and Construction of Experimental Light Aircraft, Certification of Aircraft and Aeronautical Companies, Flight Safety, Design and Construction of Lighter-Than-Air Aircraft, and the Conception and Design of Autonomous Aerial Systems, as well as experience in planning and fundraising for the development of technology projects.

He created the special shape balloons awarded in Albuquerque in 2003 (Little Bees). At Omega, he conceived, designed and led the construction of the DirBot 40 DRONI, in a network with top-tier research institutions. He co-authored an international publication on the system architecture.

Why lighter than air

In many missions, staying aloft matters more than flying fast.

Endurance, stability and payload capacity make it possible to meet a demand that small drones cannot. That is the space where Omega develops its platforms.

  • Longer flight time

    Drone batteries last a few tens of minutes. Airships carry their own weight with lifting gases and spend energy only to move and manoeuvre.

  • More payload

    Aerostatic lift allows much heavier loads than drones, on long-duration flights.

  • Stable hovering

    A platform that holds steady over a fixed point, with control along all three axes.

  • Quiet operation

    Electric propulsion keeps the airship quiet during operation.

Defence application

D3 – Drone Defense Dome: air cover to protect the mission.

In the C.A.R.T system, the D3 - Drone Defense Dome protects the military version of SLED, its casualty evacuation drone (MEDEVAC). The D3 airships, carrying a surveillance system and interceptor drones, remain over the area of operations, providing air cover and long-range monitoring for SLED. They can also provide SLED with precise positioning support, even without GNSS.

The project integrates, in a highly efficient way, both Omega’s long-standing expertise and the extraordinary technological and business capability of C.A.R.T.
