Piméné
Type Turbojet
National origin France
Manufacturer Turbomeca
First run 1948

The Turbomeca Piméné was a small French turbojet engine produced by Turbomeca in the early 1950s.[1]

First shown at the 1949 Paris Air Show this engine passed official type tests in 1950.[2] A similar, but not directly related, smaller turboshaft, known as the Turbomeca Orédon, drove an alternator and was used as an aircraft auxiliary power unit,[3]

Variants

TR-011
small 0.785 kN (176 lbf) turbojet engine, precursor to the Orédon APU.[4][5]
Piméné
enlarged 1.079 kN (243 lbf) higher mass flow development of the TR-011 / Orédon.[5]
