Definitions

  • a patented device consisting of thin rods, fixed or sliding arranged in a warp around the air inlet of the reactor, and free at their end where they meet, also has design weaknesses due to other respects. Indeed, not only a relatively bulky object endowed with sufficient energy can tangentially force the flexibility of the rods by spreading them apart, but moreover, in the event of a volatile racking at high speed on the end of these rods, there is reason to make reservations about their behavior and the cohesion of the tip of the cone which they constitute.
  • the presence of the shield makes it possible to intervene favorably on the shock wave, and the aerodynamic turbulence born from the presence of the internal folded edges of the interstitial blades, increasing in proportion to the speed, must strongly limit the pressure relative to the inside of the shield.
  • a fourth feature resides in the fact that the combination of the blades M and P is of such flexibility that the section of the shield may not only be circular as described in FIG. 2, but take the general appearance of an ellipse or of a rectangle. Or even, the shield may in these previous aspects, be divided longitudinally into 2 parts along its median axis, to be connected to the fuselage, in the case of adaptation to certain types of cells mentioned above, it is understood that the legal protection sought concerns the entire device in its spirit and that the profile of the blades as defined in this study could be modified according to the search for the best efficiency during the tests and the development.
