IPC: F02C7/045
Filed: 2001-10-23
Abstract: L'invention concerne une solution conceptuelle réalisable pour réduire de manière sélective la propagation du bruit dans une direction opposée à un flux d'air d'entrée à travers un conduit de canal d'entrée d'un turboréacteur. Cette solution s'applique par mise en place d'un soufflet pneumatique dans le conduit du canal d'entrée, afin de former un étranglement de conduit d'entrée ajustable. Le soufflet pneumatique forme, en mode inopérant, une partie de la paroi du conduit de canal d'entrée, afin de répondre aux exigences en matière de performance de turboréacteur dans n'importe quelle condition de vol. En mode opératoire, le soufflet pneumatique peut être gonflé de manière sélective et contrôlée, afin de former un étranglement ajustable, pour changer à la fois l'impédance du système par rapport à la propagation du bruit et la vitesse de passage du flux d'air entrant. Un ajustement maximal de l'étranglement ajustable peut être obtenu par augmentation de la vitesse de passage du flux d'air entrant, jusqu'à ce qu'elle atteigne la vitesse du son, afin de réduire la propagation du bruit vers l'avant, provenant du conduit de canal d'entrée, si nécessaire, par exemple dans une situation d'atterrissage d'avion.

Abstract: ABSTRACT     A method for operating a control system by solving the constrained optimization problem involved in the Model Predictive Control (MPC) approach which reduces the on-line computational requirements by a factor of about 1000.  The reduction in computational effort is achieved by replacing general purpose off-the-shelf optimization algorithms, such as, Quadratic Programming (QP) and Linear Programming (LP), currently being used in the control system, by a new specialized algorithm.  The method of the invention exploits the structure of certain MPC formulations and provides a direct (non-iterative) path to the desired solution.
