Study Notes
Electronics Fundamentals Finals - Servomechanisms
- Servomechanism is an electric control system for automatic mechanisms.
- It generates motion or force using low-energy input signals.
- Objectives include defining and describing the servomechanism principle and enumerating its aircraft applications.
Open and Closed Systems
- Open loop systems: controls are set to the desired setting.
- Closed loop/Servomechanism systems: include feedback or follow-up from the controlled unit.
Differential Transducer
- An electric device which converts the differing position of flight control surfaces into a variable electric output signal.
- This signal can be processed by the controller.
Linear Variable Differential Transducer (LVDT)
- Converts linear motion into an electrical signal.
Rotary Variable Differential Transducer
- Measures angular motion.
- Function by the rotor's motion within an electromagnetic stator field.
Synchro Systems
- Electric systems for transmitting information between points.
- Used in remote position indicators (landing gear, autopilot systems, radar).
- Types of synchro systems:
- Autosyn
- Selsyn
- Magnesyn
DC Selsyn Systems
- Consists of a transmitter, indicator, and connecting wires.
- Uses components like a resistance winding, brushes, a rotor shaft, contact arm, and a permanent magnet.
AC Synchro Systems
- AC Magnesyn uses permanent magnet motors.
- AC Autosyn uses electromagnets, differing from permanent magnets.
Modern AC Synchro Systems
- Torque Synchro Systems: for transmitting position information.
- Control Synchro Systems: for precise systems requiring feedback and control.
- Differential Synchro Systems: for applications needing relative position between objects.
- Resolver: for sensing and tracking angular positions of devices.
Inductance Transmitters
- Used in older instruments, acceleration sensors, and air data computers.
- Uses inductance windings similar to synchros, but the shape and spatial location are like the letter "E".
Capacitance Transmitters
- Used on aircraft to transmit fuel condition.
- Often used in transport aircraft fuel quantity systems.
- Depends on area of plates, distance between them, and dielectric constant of separating material.
