Technical specifications :

An articulated tail support with respect to the attachment frame. The support was designed to allow to create, manually, a complementary effort of disturbance on the empennage.
From a DC motor.
Of a bevel gear pair, with straight teeth,
From a screw - ball nut system.
Two spring rods (simulating the aerodynamic forces), with springs of two different stiffness.
A visualization device for the operation of the ball screw.
Motorized tail system with acquisition.
A part information and steering system composed:
A PCI 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 of the stepper motor, a power supply, the connections required to connect the model and the PC (not supplied).
