Abstract
A free-turbine turboshaft engine including a gas generator including at least one compressor supplied with air, a combustion chamber receiving the compressed air at the output of the compressor, and at least one generator turbine mechanically connected to the compressor by a drive shaft and driven by gases from combustion of fuel carried out in the combustion chamber, and including a free turbine supplied by the gases from the combustion after passing through the generator turbine and which drives a power shaft positioned non-coaxially relative to the drive shaft of the gas generator and supplying the power of the turboshaft engine via a reduction gear. The combustion chamber is a substantially cylindrical or frusto-conical chamber, coaxial with the axis of the generator turbine, and includes a single injector.

14. A turboshaft engine with a free turbine comprising:
-
a gas generator comprising at least one compressor supplied with air; a combustion chamber receiving compressed air leaving the compressor; at least one generator turbine connected mechanically to the compressor by a drive shaft and driven by gases arising from fuel combustion carried out in the combustion chamber; and a free turbine supplied with the gases arising from the combustion after passage thereof through the generator turbine, and which drives a power shaft not in an extension of the drive shaft of the gas generator, and supplying turboshaft engine power via a reduction gearbox, wherein the generator turbine is of axial type and the combustion chamber is a substantially cylindrical or frustoconical chamber, in the extension of the axis of the generator turbine, and comprising a single injector. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
