An atypical turbine engine for UAVs is the (Pi sign) Arielle model MK VIII.

“Small turboshaft, somewhat complex”

“The gas generating turbine”

-The main engine can be the group of turbines in the central part with exhausts on both sides.

-These turbines are driven by a small model aircraft turbojet as we see in the detail photograph.

-To the right of the upper photograph we see the reduction box with a lower output of the power shaft. On top of it is the electric starter.
