The engine was outfitted with instrumentation to measure the fuel flow rate air/fuel ratio and emissions. Additionally programmers were added to the engine to monitor the state of the engine control unit and generator controller. A switched load bank was constructed that allows applying a prescribed electrical load to the engine.

Our Generator Control Units GCU& 39;s are designed to control 28 volt turbine starter generators. They provide voltage regulation overvoltage protection line contactor pull in and generator disable during engine start. Click on airframe manufacturer for appli ion and tech data
A brushless AC/DC starter generator for use with aircraft engines the starter generator capable of both providing motive force to start the engine and generate AC and DC power for aircraft systems. The apparatus includes a main generator an exciter generator and a permanent magnet generator.
Bartington Instruments now provides large-size Ferronato Helmholtz coil sets from Serviciencia to operate with Bartington’s PA1 power amplifier and CU1 control unit. The assembly consists of up to three pairs of coils with diameters of 300 mm model BH300 and 2 m model BHC2000 . Each pair generates a magnetic field in the X- Y- or Z-axis.
tolerance. Placing the switch to the OFF position will disable the signal to the generator control unit the generator will be dropped offline and the amber GEN OFF L-R annunciation will appear. The RESET position is a momentary position that will momentarily connect the armature directly to the field creating a rapid buildup to 28.5 volts
Awesome power and function. A great marriage. There is no other PEMF system that delivers up to 500 Gauss or 50 mT milli-Tesla over the entire body. Amazingly the pulsed electromagnetic field created with the 3D unit completely envelopes and penetrates the whole body in all 3 axes length width and height .
The following shows the transfer function of the control unit: In this equation and are the adjustment parameters of control unit. Tri is the triangular signal. The excitation system can control the output voltage of the synchronous generator by changing the proportional-integral parameters accordingly. 3.2. Control Strategy of DC-DC Converter
