A TR unit reduces the voltage of alternating current and changes it into direct current.
Industry:Aviation
A training device that duplicates the flight characteristics of an aircraft. The simulator looks like the flight deck or cockpit of a specific aircraft. All the controls and instruments are computer driven, and they duplicate those in the aircraft. The controls have the same feel, and the instruments give the same indications as those in the real aircraft.
Flight simulators allow many different types of emergency situations to be simulated under safe conditions, so flight crews will know how to respond when a real emergency occurs.
Industry:Aviation
A transformer containing two or more coils wound on a core of paper or other nonmagnetic material. Air-core transformers are normally used for radio-frequency alternating current.
Industry:Aviation
A transformer usable with alternating current in the radio-frequency (RF) spectrum. Most RF transformers have an air core.
Industry:Aviation
A transformer used in an electronic circuit to match the impedance of the load to the impedance of the source of electrical energy.
Industry:Aviation
A transformer used to couple two stages of an electronic device. An interstage transformer prevents the flow of direct current from one stage to the other, and it matches the output impedance of one stage with the input impedance of the following stage.
Industry:Aviation
A transformer with the coils wound over a core of laminated soft iron. The soft iron core concentrates the lines of magnetic flux and increases the inductance of the coil. The laminations decrease the eddy current losses in the core.
Industry:Aviation
A transformer-rectifier unit that changes alternating current into direct current of the proper voltage to charge storage batteries.
The battery charger is connected to the battery with the positive terminal of the charger connected to the positive terminal of the battery, and the battery is charged until its voltage is the same as that of the charger.
Industry:Aviation
A transient condition in an electrical circuit in which a pulse of electrical energy with a high voltage and short duration appears in the circuit. Spikes are produced when an inductive load in the circuit is interrupted, and by induction from an outside source, such as a flash of lightning. Special spike-protection circuits are installed in critical electronic equipment to prevent damage from spikes.
Industry:Aviation
A transistor amplifier in which the base of the transistor is connected in such a way that it is in both the input and output circuits.
