|---|---|
| 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]
Applications
- EFW N-20
- Fouga CM.8
- Fouga CM.101R
- Fouga CM.88 Gemeaux
