B110neo – B170neo – B220neo – Instructions 6.0
Introduction
The model jet engines of the
evoJet NEO
series uses the same functional principle as a "big" jet
engine. A high performance compressor compresses ingested air, which is then heated by a fuel
flame in the combustion chamber. The heat causes the air to expand rapidly, enabling it to drive an
turbine rotor, which in turn drives the mixed-airflow compressor by a shaft (open-circuit gas
turbine).
At the exhaust cone, the hot air leaves the engine at a speed of more than 1000 km/h (620 mph),
generating the required thrust for the jet aircraft model. An electric starter motor and a new electric
kerosene ignition system allow fully automated engine control from the R/C transmitter, controlled
and monitored by the JETRONIC control unit, which regulates all operating parameters to their
optimal values.
This new generation of model jet engines does not require dangerous auxiliary gases like propane
or butane any more. Power is supplied to the engine by a separate rechargeable lithium-
manganese battery, which is used to power all system components, such as fuel pump, kerosene
ignition, valve etc.
State-of-the art precision CNC and laser cutting technology allow a previously impossible
production accuracy, ensuring both high performance and durability. The included display and
programming unit (EDT = Engine Data Terminal) is equipped with an illuminated LC-Display and
can be connected to (and disconnected from) the running system at any time to check the current
operating data or to change parameters. Besides the current operating parameters, such as
exhaust gas temperature (EGT), turbine revolutions per minute (rpm) and thrust (throttle),
additional information like total hours of operation, rpm and temperature statistics, number of
engine starts, battery voltage etc. can be displayed as well.
All parameters and user entries are displayed in plain text in a menu-based interface. The turbine
is started fully automatically via the throttle stick on the R/C transmitter. The pilot then adjusts the
desired thrust by moving the stick proptionally. The JETRONIC control unit is connected to the R/C
receiver via R/C-1. R/C-2 can be connected optionally for switching functions.
