Motorized empennage system

This system makes it possible to approach the fields of Mechanical Engineering and Electrical Engineering :
 

• Structural analysis of the empennage control mechanism
• 1 TD with corrected : role of empennage in the flight dynamics of the A320
• Functional analysis of the empennage control mechanism
• Identification of the components of the empennage control mechanism
• Schematic and geometric representations of this mechanism
• Kinematic behavior of this mechanism
• Static behavior of this mechanism
• Technical analysis, characteristics of assemblies and guides
• Definition, structure of a slave system and definition of performance
• Open loop operation of the system with obtaining graphs of kinematic and dynamic functions
• Closed-loop operation of the slave system (gain adjustment) with obtaining kinematic and dynamic function graphs

Part energy chain composed :
 

• An articulated tail support relative to the attachment armature,
• The support was conceived to allow to create, manually, a complementary effort of perturbation on the empennage
• A DC motor
• A bevel gear pair, with straight teeth,
• A screw system - ball nut,
• Two spring rods (simulating the aerodynamic forces), with springs of two different stiffness.
• A display device for the operation of the ball screw.
• Part information and piloting chain:
• A card to acquire the data
• An angular position sensor, located on the ball screw
• A potentiometric sensor located on the tilting box, measuring the angle of rotation of the empennage
• Of an acquisition chain of the following functions: voltage at the motor terminals, moment of the engine torque,
• Angular positions of the empennage, angular input and output speeds of the mechanism, overall reduction ratio
• An electrical box including the power card, a power supply, the connections required to connect the model and the PC.
• Technical file, pedagogical, resource, on cd-rom.
