On opening the Jakadofsky turbine box you will see everything pictured here along with a detailed operating and setup manual
that covers fuel tank systems, recommended exhaust designs, mounting the engine, mounting the onboard components and
very detailed instructions for calibrating the AECU unit with the supplied data console.
Every PJW engine that is shipped to customers has passed stringent factory testing. Each engine is tested at all operating speeds,
during startup and shutdown using common operator errors and at maximum power. The onboard AECU controls all aspects of the engine's operation from startup, spool up, speed
regulation, spool down and shut down, including emergency engine shutdown from the transmitter. The default AECU setup is
factory programmed for the highest efficiency to fuel consumption ratio but requires setup for engine starting.

Included with each engine are components in 3 major groups. The electronic components include the AECU, data console, glow plug
connector, battery pack, switch harness and indicator status LED.
The gaseous fuel equipment includes the 3mm PU gas lines, the gas shut off valve and the gas container with mechanical shut off valve.
The liquid fuel equipment includes 4mm PU fuel line, electric fuel pump and electric fuel shut off valve.
AECU Connections Left Side:
– Throttle lead, connects to receiver.
– Safety lead, any switched rx channel.
– Engine RPM sensor.
– Engine EGT sensor.
– Connector for data console.
AECU Connections Right Side:
– Switch harness for 6 cell battery.
– Kerosene electric fuel pump.
– Onboard electric starter.
– Glow plug.
– Propane electric shut off valve.
– Kerosene electric shut off valve.
– Engine status LED.
Data Console Functions:
RPM value for propane ignition, amount of propane, fuel pump voltage control, glow plug voltage control,
ambient temperature, idle and maximum speed.
The data console is the interface to the operating parameters for the engine. Each new engine requires
two configuration procedures, one with the transmitter turned off one with the transmitter turned on.
All setting are well detailed in the operating manual. Once the AECU has been setup, the data console
will confirm it with a message and the engine can be run using the Autostart feature. At the end of each
flight, the AECU will retain information for maximum fuel voltage needed for full throttle, average operating
temperature, maximum temperature, stop rotor time and the total engine time. The AECU retains this information
until the power switch is turned off. It is recommended to log this information as it will be a clear indicator
of a problem with the fuel system, over time.

PJW-RS Detail Photos
The pictures illustrate the original PJW-RS engine however the newer
PRO has the black housing but changes have been made internally
to produce the higher output.
|
Engine Details:
Assembled on the engine already is the EGT probe with connector, the onboard electric starter connector and the
engine RPM sensor.
Once the engine is mounted in the fuselage or helicopter the glow plug wire length can be determined
and the connector attached.
The status LED is positioned behind the main shaft and will
display the engine operating stages during start up, once the LED goes off the model can take off as the engine is
at full power.
Bottom left photo shows the cast turbine wheel (smaller inset) beside the machined turbine wheel
that is included with the PRO-SW turbine engine. |
