The first member of our all new generation VT engines, most advanced and user
friendly of its class.
This new generation engine from Jets-Munt turbines reduces
the installation effort to a minimum, greatly reducing the chance of
installation errors and wiring failures.
The ecu, an all new generation design, is integrated
inside the engine, together with the RPM sensors, temperature sensors
and valves.
This revolutionary feature, another worldwide first from Jets-Munt,
reduces the external components to be installed to only the fuel pump
and filter, enabling a very easy swap of the engine between different
airframes.
Install kit is reduced to the fuel pump only.
Besides all the improvements on electronics, Jets-Munt have
made a big investment effort in tooling, procuring and
manufacturing processes to be able to reduce the total weigh
and price significantly compared to other engines in its class.
Higlights:
Electronics:
-An all new ecu design with a state of the
art, powerful processor. More user friendly, easier to setup.
-The increased processor power enables the ecu to
check the engine parameters and processes 500 times a second for a smooth
and precise control, fast startup and precise RPM control. RPM
measurement resolution is now 10RPM and EGT is read with a precision
of 0.5ºC.
-The "black box" function stores the relevant parameters from
the engine once each 0.5s, keeping the recorded data of the
last 50 minutes of the engine run time, independently of the
number of startup cycles.
-Integrated sensors: The sensors are contained in
the same board as the ecu, reducing the possibility of a
connection/wiring error or failure to a minimum, this is the cause of
the most usual problems. The temperature sensor
is installed internally on the engine, protected and reducing the
possibility of damage.
-Integrated valves: The solenoid valves
are part of the fuel system inside the engine, reducing the
tubing and wiring to a minimum, reducing cost and reducing greatly the
possibility of failures and installation errors.
-Ecu, sensors, fuel igniter and valves
can be replaced without full engine disasembly, making the
maintenance very easy.
-New fuel pump. Manufactured by Jets-Munt, the
fuel pump include a ball bearing motor for long life and precise fuel
control. Thanks to this innovative design, the fuel pump can be
installed in vertical position or in a bulkhead, without the need of a
special support.
Engine Key features:
The small engine size and design has been engineered focused specially
on a reliable and easy to
operate engine for the new users to turbine models.
The engine has a thrust output
of >80N
(>18lb) ideal for the common trainers like Boomerang
jets, and capable of to power adequately models
up to 12kg weight.
Special
attention and care has been taken during the development to ease of use and the installation in the model and to increase the
reliability to maximum.
The internal kerostart system is of a all new design that completes the start procedure fully automated and in a record
time of a average of 45s from the pilot command to
the engine running at idle ready to take off.
The engine has a low operating temperature for a long life and fast
acceleration time, to ease the control of the plane in critical
situations like a go-around.
Weight of a engine is an important feature,
especially for tail heavy planes. JetsMunt have made a big effort to
compensate for the weight of the integrated components. The end result is
that the weight of the engine including the ecu and valves has been
reduced from other models of similar size to only
950gram.(2.09lb). As the external components needed for the
operation of the engine have been reduced to only the fuel pump, the
total installed weight of the installed engine, including the engine
support, fuel pump
and fuel filter, is only of 1.080gram (2.38lb). Including the suggested
battery (not supplied) (7,4V/2500mAh Lipo) the total weight rise to
only 1.215gram.
The VT80 can use non toxic oil, like 2T oil (JASO FC
or better) to keep the environment clean and to not arm the user and
bystanders health, it is an easily available
locally. Diesel fuel is permitted, but at the time of writing, long term tests are
still in progress.
Thanks to
the low operating temperature,
engine maintenance intervals can be increased. Standard service
interval is recomended at 25h. Our experience is that engine
life and maintenance interval is greatly influenced by the conditions
of use. Use in sandy and hot conditions (no paved runaways, airfields
close to beach or desert, engine intake in the bottom of the plane
(i.e. F-16) exercise a great amount of wear in rotating parts,
so in
these case we recommend shorter service intervals. Clean use
can extend the service intervals easily to 50h.
