Title: Helicopteres combines.
Inventor: VINCENT HUMPHERSON DAVID
IPC: B64C27/82
Filed: 1990-12-07
Abstract: Un rotor de sustentation (13,14) fournissant une majeure partie de la portance pour le décollage/atterrissage vertical, le vol stationnaire et le vol à faible vitesse d'un hélicoptère combiné (10) est entraîné, par l'intermédiaire d'un réducteur (18), par un moteur à turbine à gaz (16) ayant une tuyère d'échappement final à section variable (33). Le moteur fournit également la puissance d'entraînement d'une soufflante (21) engendrant un flux d'air à l'intérieur d'une poutre de queue (12). L'air est rejeté par des fentes (23) de la poutre de queue pour commander la circulation de l'air chassé par le rotor sur la poutre, ce qui engendre une force latérale s'opposant à l'effet du couple du rotor. L'air est également rejeté par des orifices de sortie (24,25) pour produire des forces latérales de commande de lacet. En vol à grande vitesse, la majeure partie de la portance est fournie par une aile fixe (15). La tuyère est réglée de sorte que presque toute la puissance du moteur sert à la propulsion et que le rotor et la soufflante sont déchargés. En vol à grande vitesse, la commande de lacet est effectuée par un aileron (27) et un gouvernail (28) montés sur la poutre de queue. Ainsi, on utilise au maximum la puissance du moteur pour la propulsion et la traînée de la poutre de queue est plus faible, ce qui permet d'obtenir des vitesses vers l'avant plus élevées.
Patent FR-2672678-A1 (FR)
Inventor: PHILIPPE OLIVIER
IPC: G01F23/296
Filed: 1991-02-13
Abstract: Process for locating the level of separation or interface, the position of which is unknown, between a liquid and another fluid, liquid or gas. The process consists in applying an ultrasound wave to the interface by means of a probe located at a reference point in the liquid, reflecting the wave onto the interface and sensing the reflected wave, preferably at the same point of reference, in order to define a measurement path; a time is then measured representing the time taken by the wave to traverse this path. Several reflectors are arranged at different known distances from the reference point. The time of the measurement path is used to select a reference reflector being the one among the reflectors which is the closest to the interface, at a distance from the emitter less than that from the interface. The length of the measurement path is deduced by using the time of the measurement path and the time of the reference path of the wave on the reference reflector. The invention is characterized in that there are at least two reflectors in the liquid medium, between the probe and the surface, and that the measurement of the speed of sound between the two last reflectors is used to determine the tendancy or the gradient so as to extrapolate with more precision the height of the liquid above the last reflector.
