Abstract

Aircraft with at least one chart recorder, characterized in that the aircraft (1) comprises a black box (1.1) detachable from and ejectable from the aircraft (1) in the event of an accident.

Description

The innovation relates to an aircraft with at least one black box according to the preamble of claim 1.

Today, modern aircraft are predominantly equipped with one or more flight recorders (flight recorders, voice recorders, also referred to as "black boxes") which record the operating characteristics of the aircraft, flight data and communication data. If an accident occurs, the stored data should provide information about the cause and course of the accident.

In addition, a flight recorder to facilitate the finding of an accident aircraft. For this purpose, it has its own power source and a tracking transmitter supplied with it, whose signal can be targeted by search teams. Despite this modern equipment aircraft with numerous passengers have disappeared in recent years untraceable. For example, in the case of a known aircraft accident in Southeast Asia, it was searched in vain for several months for the black box and the wreckage of the crashed aircraft. There are several reasons for this. In a fatal accident, a flight recorder can be so damaged that he can no longer fulfill his function. In a crash over the sea debris parts can sink together with the black box so low that the bearing signal of the black box can no longer be located. The capacity of the power source of the black box is also limited. If the search takes too long, the directional signals go out and the flight recorder can no longer be located.

The proposed innovation allows a more reliable location of a black box and thus accelerates emergency operations.

The innovation is explained in more detail below with reference to the drawing.

It shows

• 1 : an aircraft with a detachable black box;
• 2 : an aircraft with two black boxes;
• 3 : an accident sketch with an injured aircraft;
• 4 : a block diagram with two black boxes.

1 shows a schematic representation of an aircraft 1 in the manner of a gas-filled airship. For the purposes of the present application, however, aircraft are understood to mean all types of aircraft which are usually equipped with a black box. The aircraft 1 includes a black box 1.1 which is from the electrical system of the aircraft 1 is separable and can be ejected from the aircraft in the event of an accident. At the time T1 became the flight recorder 1.1 disconnected and out of the aircraft 1 pushed out. According to the innovation includes the black box 1.1 Recovery aids, in particular a parachute 2 and a float 3 , which unfolded at time T2 and a safe sinking of the black box 1.1 enable. When hitting a water surface prevents the float 3 a sinking of the black box 1.1 , The tracking transmitter of the black box activated during disconnection 1.1 allows finding the black box 1.1 in the context of an initiated rescue operation. In the best case, the flight recorder goes 1.1 not too far from the crashed aircraft 1 down, so that even this can be found quickly. Another improvement offers in 2 schematically illustrated embodiment of the innovation. In this version, the aircraft includes 1 at least two black boxes 1.1 and 1.2 , The black box 1.1 is, as already described above, again detachable and out of the aircraft 1 ejected trained. The second black box 1.2 On the other hand, it stays permanently with the aircraft 1 connected. The ejection and sinking of the first black box 1.1 takes place, as above with reference to 1 described. The advantages of the proposed innovation will be described below in terms of 3 illustrated accident sketch explained. An aircraft crashed over the sea 1 has the sea surface at impact 4 pierced and sunk. The timely severed black box 1.1 has safely sunk and drifts from the float 3 worn on the sea surface 4 , That of the activated tracking sender of the black box 1.1 Sent beacon signal from receivers of a search team or, as shown here, also from a satellite 5 be received.

That way, the black box can 1.1 and, in the most favorable case, the crashed aircraft 1 be located quickly. The above-described variant of the innovation with two black boxes 1.1 and 1.2 improves the chances of success of a search. As in the block diagram in 4 is shown, the safely landed flight recorder 1.1 namely a transceiver 6 include and thus act as a kind of relay station, the signal of the still with the aircraft 1 connected black box 1.2 receives and this possibly amplified re-radiates.

Claims (4)

Aircraft with at least one chart recorder, characterized in that the aircraft (1) comprises a black box (1.1) detachable from and ejectable from the aircraft (1) in the event of an accident. Aircraft after Claim 1 Characterized in that the aircraft (1) comprises at least one event of an accident event of the aircraft (1) separable box (1.1) and at least one in the aircraft (1) remaining box (1.2). Aircraft according to one of the preceding claims, characterized in that the black box (1.1) separable from the aircraft (1) comprises recovery aids (parachute 2, floating body 3). Aircraft according to one of the preceding claims, characterized in that the black box (1.1) separable from the aircraft (1) comprises a transceiver (6) and thus as relay station between the remaining in the aircraft (1) black box (1.2) and a Search receiver is used.
