Abstract
Official abstract text for this publication.
An aircraft turboprop engine has at least a low-pressure body and a high-pressure body. The low-pressure body drives a propeller by means of a first gearbox. The turboprop engine also includes means for supplying air to an air-conditioning circuit of an aircraft cabin, wherein said supply means has at least one compressor of which the rotor is coupled to the low-pressure body. The compressor has an air inlet connected to means for bleeding air from an air inlet duct of the turboprop engine.
First claim
Opening claim text (preview).
1 . An aircraft turboprop engine comprising at least one low-pressure body and one high-pressure body, the low-pressure body driving a propulsion propeller by means of a first gearbox, the turboprop engine further comprising means for supplying air to an air-conditioning circuit of an aircraft cabin, wherein said supply means comprise at least one compressor, the rotor of which is coupled to the low-pressure body, said compressor comprising an air inlet connected to means for taking off air from an air inlet sleeve of the turboprop engine. 2 . The turboprop engine according to claim 1 , wherein the rotor is coupled to the low-pressure body by means of the first gearbox. 3 . The turboprop engine according to claim 1 , wherein the rotor is coupled to the low-pressure body by means of a second gearbox. 4 . The turboprop engine according to claim 1 , wherein a heat exchanger is either mounted between the air inlet of the compressor and the takeoff means, or between two compressors or between two compressor stages. 5 . The turboprop engine according to claim 1 , wherein the compressor comprises an air outlet connected to a pipe intended to be connected to said circuit, said pipe being equipped with at least one regulation means such as a valve. 6 . The turboprop engine according to claim 5 , comprising a pneumatic starter, an air inlet of which is connected to said pipe. 7 . The turboprop engine according to claim 5 , wherein the pipe is equipped with a heat exchanger. 8 . The turboprop engine according to claim 1 , wherein said turboprop engine is configured so that the speed of rotation of the low-pressure body is substantially constant whatever the operating conditions. 9 . A method for supplying air to an air-conditioning circuit of a cabin of an aircraft that is equipped with at least one turboprop engine comprising at least one low-pressure body and one high-pressure body, the low-pressure body driving a propulsion propeller by means of a first gearbox, said method comprising the steps involving taking off air from an air inlet sleeve of the turboprop engine, supplying at least one dedicated compressor with the air taken off and driving a rotor of said compressor by means of the low-pressure body of the turboprop engine.
