Quels sont les avantages du GVT?

  • Le glissement vieillesse technicité (GVT) s'avère alors un phénomène pivot pour expliquer les variations de masse salariale dans le secteur de la fonction publique. Ainsi, l'effet GVT permet de mieux évaluer les augmentations de salaire moyen qui touchent les fonctionnaires en France.

Qu'est-ce que le GVT négatif ?

  • Dû à des concours internes ou encore des promotions à l'ancienneté, cet indicateur est aussi prévisible qu'automatique. Le GVT négatif désigne l'impact négatif sur la masse salariale du remplacement de fonctionnaires en fin de carrière par de nouveaux arrivants moins bien rétribués (effet entrées/sorties). On parle dans ce cas d'effet de Noria.

Quels sont les effets de la QVT?

  • Les effets de la QVT sont ainsi déclinés selon quatre dimensions : psychologiques (motivation, satisfaction au travail…) santé (bien-être, réduction du stress, préservation de l’intégrité physique…) économiques (performance, productivité, innovation…)

Qu'est-ce que l'effet GVT ?

  • L’effet GVT qui se caractérise par la variation de la masse salariale entre deux périodes à partir du phénomène de Glissement (augmentation de salaire dû à une promotion), du Vieillissement (augmentation des salaires dû à l’ancienneté) et de la Technicité (augmentation de salaire dû à l’acquisition d’une nouvelle qualification technique)

•Free-Free: On Soft Supports

To simulate free-free boundary condition flight and to separate the aircraft rigid body modes from its elastic modes

Multiple tests were conducted on the aircraft at a variety of different shaker locations in order to excite the target

modes

Yoke & pedals were locked for the most part, except for one test case that when the yoke was free in order to excite the Stab Rotation mode

Gust locks on the aileron and rudder, as well as the stab counterweight, were either installed or removed from time to time depending on the target mode to be excited

•On-Tires

To verify the taxi ground modes prior to flight and cross-check with the on soft support modes for any significant

differences

Also to obtain the baseline characterization of the motor assembly modes for safety clearance of near-term ground

motor testing before flight Yoke & pedals were locked, all gust locks were removed, and stab counterweight was off For the motor test, aileron & rudder gust locks were installed as well as the stab counterweight

•Additional last minute configuration was added during the GVT by exciting on the A-Frame lifting device

directly in order to ensure there was no coupling to the aircraft modes of interest X

•GVT results processed in BK Connect with different parameter estimation techniques for both setups: Free-

Free vs. On-Tires

•Many modes were found during the GVT that were missing in the pre-test FEM

•Asymmetries were seen between the left and right sides of the vehicle, particularly in the control surfaces, and

were seen in all of the test configurations

•GVT modes for On-Tires setup do not necessarily follow the order in the Free-Free setup, with several modes

not observed or missing •Several modes from the Free-Free setup are coupled together in the On-Tires setup case

57 Mod II GVT -Motor Results

19 •Motor results will focus on comparisons of the two main setups: Free-Free vs. On-Tires

•Stab counterweight block installed, all control surfaces locked and cockpit locks (yoke & pedals) on

•Post-processing a bit tedious as motion from the wings and control surfaces tend to dominate over any motion from the

motor assemblies

•Motor modes fell between 29 -35 Hz for both setups, with the anti-symmetric motor lateral mode being the most different

between setups

•Similar to the aircraft results, asymmetries were observed again between the left and right motor assemblies

57 Mod II GVT -Rigid Body Results

•Aircraft rigid body tests were performed while the aircraft was installed on soft supports in order to identify the

approximate frequencies of the 6 different rigid body modes and to evaluate the frequency separation between the highest rigid body mode (1.06 Hz) and the first aircraft elastic mode (7.83 Hz)

•Manual excitation was provided from test engineers and shakers were not used for rigid body tests
