We are looking for a new generation to take our know-how and expertise into the future.

GEN-H4 well-known as the smallest helicopter in the world, GEN CORPORATION will re-structure its heritage to unmanned air transportation system as GEN AIR TRANSPORT SYSTEMS (= GEN ATS).

Its special and innovative features include:

  1. Co-axial reversing rotor blade: it does not require a tail rotor.
  2. Fixed pitch rotor blade: it allows to obtain a very simple structure.
  3. Unique gear box:
    • - enables to yaw* control without tail rotor
      *Yaw Control = turn around left and right with hovering at the spot.
    • - provides the rotor blade power
    • - has also several ports of input. Those ports enable to use complexed power sources like engines and electric motors at the same time.
      It allows GEN ATS to have hybrid combination of different power sources suits for the purpose at the same time.
  4. GEN has no specified shape.
    • - GEN structured by the power units, Gear box, Roter Blades and the cargo instead of fuselage.
    • - Combine those 4units in variation aligning with the purpose allows GEN ATS easy to optimize its structure at the purpose.
    • - This feature gives GEN ATS no specified shape.
  5. Versatility:
    it can be set up for several configurations according to the use chosen - e.g. cluster flying to carry a heavy cargo.

‘The team of GEN-H4 is now looking for reliable investors and shareholders, responsible for the product, its quality and safety, in order to:

  1. Further develop the project together with its inventor, eager to keep up with his idea and see it finalized and marketed.
  2. Enhance its top-tier technology.
  3. Develop the interface of each element, so as to create safe, reliable and above all modular products to meet every customer’s needs, and to organize a long-term customer service for the supply of GEN know-how, spare parts and possible customizations.

  4. In short, GEN is looking to finalize the project thanks to investors who believe in the project and can take this high-tech, innovative transport system into the future.

    GEN ATS, that has a performance that fulfil the demands of air transportation by helicopter, contains the potential to dominant global air transportation market.

    It means the successor of GEN Corporation seize the opportunity to be the authority of authorizing the global GEN ATS that brings huge potential of domination of air transportation in future.
