Publication number: 20140061389Abstract: An aeroengine control device including a mount and having pivotally mounted thereon a code wheel together with a main lever and a secondary lever, both for turning the code wheel. Each lever is movable between a rest position and a maximum actuation position. The secondary lever is mounted to pivot on the main lever. Cam paths are mounted on the code wheel and on the mount in such a manner that the main lever can move the code wheel when the main lever is moved while the secondary lever is in the rest position. The secondary lever can move the code wheel when the secondary lever is moved while the main lever is in the rest position, with movement of either lever being prevented when the other lever is clearly away from its rest position.Type: ApplicationFiled: September 30, 2013Publication date: March 6, 2014Applicant: SAGEM DEFENSE SECURITEInventors: Hafid ELABELLAOUI, Jean-Eric BESOLD, Sebastien PAUTARD, Thierry CARTRY, David ENGLER, Etienne MERLET
