Engine Installation - Carf-Models MiG-15 Construction Manual

9. Engine installation

First of all, we show the
installation of a JetCat P-
120SX.
If you use other engine brands,
go ahead. Any engine between
8.5 and 12 kg of thrust will do
fine.
We do not mention the
installation of the additional
components such as fuel
pump, gas tank, valves, and so
on, as any engine requires
different accessories.
Whenever the pictures will give
you an idea of where it might
makes sence to install certain
components.
CG-matters might require to
move these components
around in the fuselage, so we
recommend to install these as
the very last.
The Enging Mounting rails are
already pre-installed, so the
position for the Engine is given
by that position. Installation of
the engine be a natural thing,
too. It mounts on the
preinstalled rails, by using the
supplied M4 x 16 screws and
M4 T-nuts.
Assemble the ducting first.
Glue the rear cone into the
bottom duct (the one with the
mounting brackets molded in).
Mount the stainless thrust tube
to the rear end of the cone,
and slide the whole unit into
the fuselage. Rear end of the
thrust tube is held by the rear
former. Install a plywood piece
in the rear end of the fuselage,
to mount the outer aluminum
tube to with just one sheet
metal screw. Basically the tube
is held by the mounting screws
to the carbon cone in the front.
This rear fixture is just for
avoiding the aluminum tube to
slide out.
