HYBRID REACTIVE PROPELLER WITH COANDĂ EFFECT AND FLYING-TAXI AIRCRAFT USING IT

The invention relates to a hybrid reactive propeller with Coandă effect and a flying-taxi aircraft using it. According to the invention, the propeller consists of a casing (4) with a taper part (a) continued with a cylindrical part (b) at the inlet of which there is positioned an electric motor (5) with its shaft made integral with a tubular hub (1) with a number of 2...3 suction airscrews (B1, B2 and B3) made with rectangular or trapezoidal radial blades (2), each such blade having the edge made integral with a marginal blade (3) with the length in the rotation plane but oriented under an angle (γ) in relation to the tangent to the rotation circle, the cylindrical part (b) having a number of 4...8 thermo-reactive propellers (7) with a sparking plug (11) and a nozzle (8) fixed at the end of a fuel pipe (9) coming from a fuel tank (R) by means of a system (S) with an electro-pump (10) and an electro-valve (g), the propellers (7) driving three downstream airscrews (D1, D2 and D3) with radial heat-resistant blades (7), made integral with a hub (1') fixed onto the lower end of the electric motor (5) shaft which, after the start of the hybrid propeller, is switched to the function of electric generator. The claimed aircraft has a body (A) and two wings (C1 and C2) of a relatively large surface, each with a part of aileron (14) and a hybrid ascension propeller (P1 and P2), in the back side it has a propeller (V1 and V2), preferably an electric downstream one, with a double electric motor (19) with two counter-rotation airscrews (22 and 22'), fixed onto a ring-like casing (21) which may be rotated and, over the air inlet of the hybrid propellers (P1 and P2), there is a metallic shutter (15) for opening/closing the air inlet made of two symmetrical halves actuated by the rods of electric linear actuators (16). Invenţia se referă la un propulsor hibrid reactiv cu efect Coandă şi aeronavă tip taxi zburător care îl utilizează. Propulsorul, conform invenţiei, este compus dintr-o carcasă (4) cu o parte (a) tronconică continuată cu o parte (b) cilindrică la intrarea căreia este poziţionat un motor (5) electric cu axul solidarizat de un butuc (1) tubular cu un număr de 2...3 elice (B1, B2 şi B3) de aspiraţie realizate cu nişte pale (2) radiale dreptunghiulare sau trapezoidale având marginea solidarizată cu câte o pală (3) marginală cu lungimea în planul rotaţiei dar orientată într-un unghi (γ) faţă de tangenta la cercul rotaţiei, partea (b) cilindrică având un număr de 4
