A turboshaft engine developed specifically for the Lynx Helicopter.
This example is mounted on a pallet and is ready for shipping. This engine is an ex college instructional/training engine and is identified as such on the data plate. The engine looks to be an example that at the end of its service life has then been used for instructional training use. The front has the compressor fan installed which rotates when turned by hand, the rear end has the turbine installed which once again rotates when spun by hand. It is noted that the cooling fan for the oil cooler spins very freely with no resistance so it may be that the internal gears/driveshaft for this component are not installed?
Condition and completeness is as per the photos. Ideal museum display engine or college instructional piece. Due to the former “Training Aid Engine” history on this example it is probably not suitable for ground running applications such as use in speed boats etc without thorough inspection and overhaul. Ideal spares source for rebuilding an existing Gem core.
