Installation – X45TP TurboProp engine
The engine unit is designed to operate horizontally with the
engine markings upwards. A side and plan view can be
downloaded from

. Use the link to check
for other sizes of mounting and views and propeller sizes to suit
specific airframes as they become available.
Use the special mounting supplied as part the engine. It provides
critical support at the important positions required and aids heat
dissipation from the small gearbox. It also gives the engine
section gentle support and allows for expansion lengthways as
the unit warms up in operation. It also provides some limited
shielding from the hot interstage part between the engine and 2
nd
stage.
Note the solid fixing of the gearbox to the mounting and through to
the firewall, critical in providing a stiff, yet load sharing pathway.
This simple but rigid framework provides a lot of engine protection
in event of a nose over or crash, however this stress will be passed
directly to the firewall so must be a secure point in the airframe.
Without such a system any significant prop-strike or nose over
could banana (bend) the 2
nd
stage, a very expensive repair.
A template is provided to place over and position mounting holes and cutout for the firewall. It can also
be downloaded from

. Use the link to check for other sizes of mounting and
views to suit specific airframes and exhaust patterns as they become available.
The engine requires a flow of cool air to its intake to operate. This is ideally forward facing to take
advantage of prop and airframe airflow. Make provision for this
separate
from any airflow used for
cooling in the cowl area, perhaps passing underneath a separator. If this flow passes through the front
undercarriage area place a fine mesh similar to used on the fod screen to prevent stones, grass etc
being pushed into the engine area during ground manouvres.
