Definitions

  • the bearings play an important role.
  • the jet engine is completely flooded.
  • the bearings are made of seawater-proof carbide.
  • the structure of the bearings can be seen out FIG. 4 , See there the bearing segments 14, 15 which are embedded in the housing 9 and 10 respectively.
  • the bearing segments 14, 15 are dovetail-shaped in cross-section, and the housing has corresponding recesses.

Claims (6)

  1. Propulsion par réaction
    1.1 comprenant deux ou plusieurs unités disposées axialement l'une derrière l'autre;
    1.2 chaque unité présente les composants suivants ou les caractéristiques suivantes;
    - un rotor sans moyeu (3, 4) à la périphérie interne duquel sont fixées les lames de rotor (1, 2);
    - un bâti (9, 10), dans lequel le rotor (3, 4) est monté rotatif;
    - chaque rotor (3, 4) est entouré par un moteur électrique avec bague de rotor (5, 6) et bague de stator (7, 8);
    - la bague de rotor (5, 6) est connectée de manière solidaire en rotation avec le rotor (3, 4);
    1.3 les deux moteurs électriques sont conçus selon des sens de rotation opposés.
  2. Propulsion par réaction selon la revendication 1, caractérisée en ce que l'ensemble roulement entre le rotor (3, 4) et le bâti (9, 10) est en carbure résistant à l'eau de mer, de préférence carbure de silicium ou carbure d'aluminium.
  3. Propulsion par réaction selon la revendication 1 ou 2, caractérisée en ce que l'ensemble roulement entre le rotor (3, 4) et le bâti (9, 10) est exclusivement en carbure.
  4. Propulsion par réaction selon l'une quelconque des revendications 1 à 3, caractérisée en ce que l'ensemble roulement est constitué de paliers de glissement.
  5. Propulsion par réaction selon l'une quelconque des revendications 1 à 4, caractérisé en ce que les vitesses de rotation des rotor (3, 4) des unités sont réglables indépendamment l'une de l'autre.
  6. Propulsion par réaction selon l'une des revendications 1 à 5, caractérisée en ce que le palier axial arrière d'un propulseur avant, vu dans le sens de la marche, tourne contre le palier avant d'un propulseur arrière, vu dans le sens de la marche.
