1. An emergency power supply device for aircraft, comprising: at least one air intake duct configured to receive airflow during a flight of the aircraft;a turbine arranged in the duct, to be driven by the relative airflow; andat least one generator for generating power for the aircraft, the turbine
1. An emergency power supply device for aircraft, comprising: at least one air intake duct configured to receive airflow during a flight of the aircraft;a turbine arranged in the duct, to be driven by the relative airflow; andat least one generator for generating power for the aircraft, the turbine being connected to the power-generating device to produce power for the aircraft at least under flight conditions thereof;wherein the turbine and/or the generator is/are connected to or associated with at least one auxiliary drive device of the turbine and/or the generator, the auxiliary drive device being a device with a venturi tube supplied by a source of air, and arranged or formed in the air intake duct to drive the turbine. 2. The emergency power supply device for aircraft as claimed in claim 1, wherein the auxiliary drive device is configured to be coupled to the turbine to drive the turbine, or to be uncoupled from the turbine. 3. The emergency power supply device for aircraft as claimed in claim 1, wherein the air intake duct includes at least one air inlet and/or air outlet flap, mobile in an adjustable manner, between a closed and an open position. 4. The emergency power supply device for aircraft as claimed in claim 3, further comprising a control unit connected to the power-generating device for the aircraft, to the auxiliary drive device, and to the air inlet and/or air outlet flap, and configured to control the device as an automatic control of a required power. 5. The emergency power supply device for aircraft as claimed in claim 1, wherein the auxiliary drive device is a venturi tube device supplied by a source of air of the aircraft, and arranged or formed in the air intake duct to drive the turbine. 6. An aircraft provided with an emergency power supply device as claimed in claim 1, wherein the generator is a generator of electrical power of the aircraft. 7. The aircraft as claimed in claim 6, wherein the air intake duct includes an inlet formed in a body of the aircraft fuselage, a main part formed in the body of the aircraft fuselage, and an outlet formed in the body of the fuselage, the inlet and/or the outlet including an air outlet flap and opening out on a surface of the body of the fuselage. 8. The aircraft as claimed in claim 6, wherein the generator is connected through a freewheel to an APU device of the aircraft to allow the generator to be driven by the APU device in normal mode and to leave it to be driven by the turbine in the event of a failure of said APU device, or connected to a motor/engine, to allow the generator to be driven by the motor/engine in a normal mode and to leave the generator to be driven by the turbine in event of a failure of said engine. 9. A utilization of an electrical power generator for an aircraft as a source of emergency electrical power for the aircraft, the generator configured to be driven by at least one turbine arranged in an air intake duct of the aircraft to be driven by relative airflow of the flight of the aircraft, wherein the turbine and/or the generator is/are connected or associated with at least one auxiliary drive device of the turbine and/or the generator,the auxiliary drive device being a device with a venturi tube supplied by a source of air, and arranged or formed in the air intake duct to drive the turbine.
