Francesco Talotta provided several design files (thank you!) for the Airbus canon plugs and the trim wheel motorisation system. Sample screenshots of one of the plugs and the plate: # Airbus OEM TRIM MOTOR ## Components: * Maxon Motor 144650 * Huco 273.25.2828 clutch, 6mm hole diameter (RS) * Vishay 534 10kΩ potentiometer, 6mm shaft … Continue reading
The Airbus trim wheel can be interfaced directly with Jeehell FMGS using the Sidentus Trade & Technology GmbH FDSMotorTrimWheelCtr software. Requirements – Jeehell FMGS, PhidgetMotorControl HC, FSUIPC (registered), potentiometer (joystick) I/O, Phidget21 Libraries First ensure the trim has been mechanically setup correctly. A DC motor attached to a clutch and gears connected to a potentiometer … Continue reading
The following is a tutorial on how to setup a motorized trim wheel using a Pololu hardware feedback interface board and ProsimA320. Alternative avionics software such as Jeehell FMGS does not have native Pololu compatibility and will require additional driver support, such as FSUIPCtoPololu from TNS-Systems. Hardware trim setup can be reviewed over here. Wire … Continue reading
Motorization of the trim wheel requires extensive engineering. Parts required: Original design and implementation by Simon and Holt Tutorial: Trim Wheel Interfacing (Jeehell FMGS) Configuration of the Trim Wheel (Pololu Jrk) Trim Motor Design Files (Francesco Talotta) Continue reading
When you literally have hundreds, if not thousands of parts lying around waiting to be put together (a giant jigsaw puzzle) you may tend to have multiple mini-projects developing concurrently. The following solutions are currently being developed – ASI integration with a digital servo (thank you Mick) RMP refurbishment / repair Trim Wheel software/hardware implementation … Continue reading
Some notes from Simon: Opencockpit DC Motor Board (interfaced with SIOC) Takanawa 555 metal gear DC motor, attached to home made plastic motor carrier bracket Lower trim axis rotates six times, multi-turn pot rotates ten times; requires a gear ratio 1.5 or 1.6 (45 vs 30, or 48 vs 30 teeth) Original movable joint if motor … Continue reading
There are several ways to motorize the trim wheel of the Airbus. The A320, unlike the Boeing 737, has autotrim built into the aircraft systems. Boeing pilots are required to trim the aircraft to an angle of attack of 1 G — this is done with the trim switch on the yoke. On the A320 … Continue reading
