Abstract:
In a process and an apparatus for the avoidance of bird impacts on airplanes by means of at least one light-flashes generating light source on an airplane, for which the frequency of the generated light flashes is varied through at least one cycle, the flash frequency is varied dependent upon the speed and/or the altitude and/or the acceleration of the airplane in order to provide an optimal flash frequency range for all take-off and landing phases and at the same time to be independent of a load and the type of airplane.
Abstract:
In a process and an apparatus for the avoidance of airplane collisions in which at least one light source of a light flash warning apparatus on an airplane generates light flashes at periodic intervals, light flashes with a constant frequency are emitted from a first light source and light flashes with a variable frequency are emitted from a second light source, thereby increasing the warning effectiveness, localizing capability and, thereby, safety during operation of the airplane.
Abstract:
In flashing light warning apparatus of a type having a voltage source (U), a main blocking transformer (HW), a flash tube (R), an ignition device (Z), a first and a third storage condenser (K1, K3), and an electrical switching device (S1), a switching path of the first electrical switching apparatus is arranged parallel to the first storage condenser, the third storage condenser and the ignition device are coupled to an auxiliary blocking transformer (ZW), and the first switching device can be switched by a control device (B). Such a flashing light warning apparatus can be produced in an uncomplicated, cost effective manner, to provide light energy which can be changed during operation to provide a day flash and at least one type of night flash. The night flash is at such a level that its output can be recognized from afar only by night vision apparatus.
Abstract:
A flashing light warning apparatus, which includes a voltage source (U), a main gate transformer (HW), a flash tube (R), an ignition device (Z), at least one storage condenser (K), and an electrical switching device (S), can be switched to provide light energy for daytime flashes and nighttime flashes in an uncomplicated, cost effective system which produces dependable light flashes. The night flashes have a light energy such that they can be seen from afar only with night vision apparatus. When the switching device turns off voltage production of the main gate transformer or further transmission of voltage from the at least one storage condenser, the ignition device is coupled to an auxiliary gate transformer (ZW) for carrying out light flash production by means of high frequency ignition voltage produced by the ignition device.
