2.2. Engine mounting rules
The engine must be installed in a way that the fuel starter tube
is in the 12 o'clock position
. This is absolutely vital for proper
kerosene start on the
B300F
engine. Otherwise, the start, i.e.
the ignition, would fail and might even lead to engine damage.
There must not be any flammable objects near the turbine. The
turbine must not be touched by flammable objects.
The nozzle and the whole area in the neighborhood of the jet
exhaust must be kept clear of any objects.
In case of mounting within a bypass enclosed system, the rear
end of the installation area and any parts which could be
affected by the hot jet exhaust should be protected with non-
flammable materials (danger of fire!). When an extension of the
nozzle is necessary, it must be constructed and installed
according
to the manufacturer’s specifications (overheating!).
The turbine must be installed in a way that it can be cooled by
a bypassing air stream.
Combustible liquids and gases as well as tanks and tubes must
be kept away from or installed at a safe distance from the
engine.
The intake area (impeller / compressor) must be kept clear.
Any wires, tubes, etc. must be installed and fixed in a way they
cannot be sucked into the turbine. In general, there should not
be any objects or installations close to the front end of the
turbine.
The intake section of the model should have at least twice the
area of the impeller/compressor wheel.
You must make sure that no objects, e.g. rocks, dirt, screws,
etc., can be sucked into the turbine. It is a good idea to protect
the turbine intake with a Foreign Object Damage screen (see
accessories for FOD screen).
The intake area must absolutely be kept clear.
The vacuum
generated by the intake is very strong. Make sure that the
intake duct is reinforced with carbon fiber, especially if it is
long.
