Abstract: L'invention concerne un procédé de formation d'un signal de sortie à fréquence porteuse à partir de n signaux partiels d'une bande de fréquences de base. Chacun des n signaux partiels est attribué en tant que signal d'entrée à une branche principale respective, dans laquelle le signal partiel correspondant est limité en amplitude, filtré et converti en un signal partiel à fréquence intermédiaire. En tant que signaux de sortie de la branche principale, les n signaux partiels à fréquence intermédiaire sont regroupés en un signal de somme commun. Ce signal de somme est limité en amplitude, soumis à une conversion numérique-analogique et converti en signal de sortie à fréquence porteuse. En outre, chaque signal partiel parvient à une branche auxiliaire, à l'aide de laquelle des surélévations probables du signal partiel dans la branche principale correspondante peuvent être déterminées comme valeurs estimatives. A l'aide de ces valeurs estimatives, les limitations d'amplitude des signaux partiels correspondants, exécutées dans la branche principale, peuvent être régulées dans ladite branche.

Title: Extended operability aircraft fuel delivery system
Inventor: KASLUSKY SCOTT
IPC: B01D61/00
Filed: 2005-01-13
Abstract: A fuel delivery system for a gas turbine engine includes a main fuel pu mp supplying fuel to a fuel-metering device. The operational flow range of the fuel system is dependent on a minimum net positive suction pressure at the main pump inlet required to prevent pump cavitation. A mixture of fuel and dissolved gases increases the minimum net positive suction pressure required to prevent cavitation. A fuel de-aerator including a permeable membrane removes dissolved gases fr om the fuel to eliminate formation of dissolved gases. The elimination of dissolved gases from within the liquid fuel reduces the required net positive suction pressure, enabling a greater operational flow range.
