From these, the aircraft cost will be less than 1Z2 for a helicopter, and to 1Z20 in the future The fuel consumption will be less than 1/4. This can be done by using two propellers (or propulsion) before and after the launch, using a catamaran and flaps.

  • Helicopter now costs 100 million'20 million yen for a helicopter It was about 200,000 yen, about 200,000 yen, and many people could use it as easily as a car, and millions to tens of millions of vehicles were used in each country. More than 10,000 aircraft can cooperate and solve social issues such as Indonesian forest fires immediately.

Abstract

L'invention concerne un aéronef à décollage et atterrissage verticaux comprenant des hélices (1, 2) situées à l'avant et à l'arrière d'une aile (3) principale, l'hélice avant (1) étant disposée de manière à tirer vers l'avant une cellule et un souffle provenant de l'hélice (1) fournissant une portance à l'aile (3) principale; l'hélice arrière (2) est disposée de telle sorte que le souffle provenant de l'hélice arrière est dirigé vers l'extrémité arrière de l'aile (3) principale afin de soulever la cellule et d'empêcher une réduction de l'efficacité de la portance en raison de la séparation du souffle par l'hélice avant (1) à partir de la surface supérieure de l'aile principale (3), d'une zone près du centre à l'extrémité arrière, ce qui permet d'obtenir une grande portance.
