A power generation system for integration into an aircraft system, including a secondary power supply device having a generator turbine arranged in a duct running between a forward opening and a rearward opening on the fuselage of the aircraft. An electromagnetic unlocking device locks and unlocks a covering device on the forward opening, depending on a signal strength supplied to the unlocking device. The system also includes an actuation device that generates an opening or closing signal for an opening and closing device, and an opening function switching device that activates the unlocking device electrically with a signal strength that locks the covering device in an initial state, and on receipt of a power requirement signal from a power generation monitoring device, activates the unlocking device with a second signal strength that unlocks the covering device.

1. A power generation system for integration into an aircraft fuselage, the power generation system comprising: a secondary power supply device, comprising: a duct running between two openings on the fuselage, wherein one is a forward opening and the other a rearward opening along an aircraft longitudinal direction,a turbine arranged in the duct with a generator coupled to the turbine,a covering device, movable between a closed and an open position for covering the forward opening in its closed position,an opening and closing device, andan unlocking device, which is assigned to the covering device and which is configured such that the unlocking device locks the covering device if a current with a first signal strength is supplied to the unlocking device, and unlocks the covering device, if a current with a second signal strength is supplied to the unlocking device wherein the second signal strength is less than the first signal strength;at least one actuation device that is functionally connected with the opening and closing device for generating an opening or closing signal for the same; andan opening function switching device that is functionally coupled with a power generation monitoring device, wherein the opening function switching device is also functionally connected via a control cable with the unlocking device;wherein the opening function switching device is configured such that in an initial state the opening function switching device activates the unlocking device electrically with the first signal strength, with which the unlocking device locks the covering device; andwherein on receipt of a power requirement signal from the power generation monitoring device the opening function switching device activates the unlocking device electrically with the second signal strength, with which the unlocking device unlocks the covering device. 2. The power generation system in accordance with claim 1, wherein the unlocking device can be actuated electromagnetically. 3. The power generation system in accordance with claim 1, wherein the covering device is configured as a cover, which is articulated on the fuselage by an articulation, such that the articulation is positioned on the rearward side of the forward opening along the longitudinal direction of the aircraft; andwherein the cover is configured such that wind forces in flight push the cover into the open position. 4. The power generation system in accordance with claim 1, wherein the at least one actuation device is configured such that the at least one actuation device can be actuated manually. 5. The power generation system in accordance with claim 1, wherein the rearward opening of the duct is constituted in terms of an outlet opening on a rear section of the aircraft fuselage. 6. The power generation system in accordance with claim 1, further comprising: a second duct in the aircraft fuselage having a forward and a rearward opening, wherein the forward opening is an inlet and the rearward opening is an outlet;wherein a coupling section connects the outlet of the second duct to the rearward opening of the first duct; andwherein an auxiliary turbine is installed within the second duct. 7. The power generation system in accordance to claim 1, wherein a second covering device, movable between a closed and an open position, is arranged on the rearward opening for covering the rearward opening in the closed position;wherein a second opening and closing device and a second unlocking device are assigned to the second covering device, the second unlocking device being assigned to the second covering device and configured such that the second unlocking device locks the second covering device if a current with a first signal strength is supplied to the second unlocking device, and unlocks the second covering device if a current with a second signal strength is supplied to the second unlocking device, wherein the second signal strength is less than the first signal strength;wherein the power generation system has at least one actuation device for purposes of generating an opening or closing signal for the second opening and closing device, which is assigned to the second covering device; andwherein the opening function switching device is functionally coupled via a control cable with the second unlocking device, and is configured such that in an initial state the opening function switching device electrically activates the second unlocking device with a first signal strength, with which the second unlocking device locks the second covering device, and that on receipt of a power requirement signal from the power generation monitoring device the opening function switching device electrically activates the second unlocking device with the second signal strength, with which the second unlocking device unlocks the covering device. 8. The power generation system in accordance with claim 7, wherein the second unlocking device can be actuated electromagnetically. 9. The power generation system in accordance with claim 8, wherein the second covering device is configured as a cover, which is articulated on the fuselage by an articulation positioned on the rearward side of the rearward opening along the longitudinal direction of the aircraft; andwherein the cover is configured such that the wind forces in flight push the cover into the open position. 10. The power generation system in accordance with claim 7, wherein the second covering device has a cover, which by a rotational articulation is arranged such that the cover covers the rearward opening if the cover is located in its closed position; andwherein the rotational articulation is positioned on a side forming the forward side of the rearward opening in the aircraft longitudinal direction. 11. The power generation system in accordance with claim 7, wherein the at least one actuation device is configured such that the at least one actuation device can be actuated manually.
