Signal strength dependent cover unlocking device for a duct housing a secondary power supply device in an aircraft fuselage

摘要

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; and an 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; and wherein 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.
