Abstract

A missile equipped, for example, with a time fuse contains a microprocessor (10), to which specific relevant signals are fed and which initiates specific control functions in response to these signals. At the same time, this microprocessor (10) enters data relevant to the flight and to the functioning of the fuse into an EEPROM memory (18) which permanently stores these data. After an impact or break-up of the missile, this memory (18) can be salvaged, and in the manner of a flight recorder the information contained in it can be used for analysing the malfunctioning or functioning of the fuse contained in the missile. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen Flugkörper nach dem Gattungsbegriff des Patentanspruches 1.The present invention relates to a missile according to the preamble of claim 1.

Bestimmte Flugkörper, wie beispielsweise Raketen und Geschosse, sind in der Regel mit einem Zünder versehen, wobei es im Falle von Fehlfunktionen aber auch zum Funktionsnachweis von Interesse ist zu erfahren, warum eine Fehlfunktion vorliegt oder aufgrund welcher Ursachen die Funktion ausgelöst wurde. Um dies zu erfahren, werden speziell zur Erprobung und Fehleranalyse Telemetrie-Raketen bzw. Geschosse gebaut, die über entsprechende Antennen und eine Funkverbindung Flugdaten zu einer Bodenstation übermitteln, so daß mittels aufwendiger Meßreihen Erkenntnisse über die Ursachen einer Fehlfunktion bzw. der Funktion erhalten werden können. Diese Untersuchungen sind immer sehr teuer und verlangen einen sehr großen Aufwand für die Adaption und Modifikation der Flugkörper. Fehlerbeseitigungsprogramme verursachen enorme Kosten und verzögern die Serienreifmachung der Produkte. Plötzlich auftretende Fehler bei Losabnahmen können nur schwer lokalisiert werden und ziehen den Stopp ganzer Produktionen nach sich.Certain missiles, such as missiles and projectiles, are usually provided with a detonator, but in the event of malfunctions, it is also of interest to find out why a malfunction has occurred or what caused the function to be triggered. In order to experience this, telemetry missiles or projectiles are built specifically for testing and error analysis, which transmit flight data to a ground station via appropriate antennas and a radio link, so that knowledge of the causes of a malfunction or the function can be obtained by means of complex series of measurements . These investigations are always very expensive and require a great deal of effort for the adaptation and modification of the missiles. Troubleshooting programs cause enormous costs and delay the readiness for series production of the products. Sudden errors in batch acceptance can only be located with difficulty and result in the stoppage of entire productions.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Flugkörper der eingangs genannten Art so auszubilden, daß er durch eine nur geringfügige Modifikation praktisch mit einem Flugschreiber versehen wird. Die Lösung dieser Aufgabe gelingt gemäß den kennzeichnenden Merkmalen des Patentanspruches.It is therefore the object of the present invention to design a missile of the type mentioned in the introduction in such a way that it is practically provided with a flight recorder by only a slight modification. This object is achieved in accordance with the characterizing features of the patent claim.

Als Flugschreiber dient erfindungsgemäß ein EEPROM-Speicher, in den ein Mikroprozessor die während des Fluges des Flugkörpers auftretenden relevanten Informationen in codierter Form einschreibt. Dieser Speicher kann nach einem Aufschlag oder einer Zerlegung des Flugkörpers geborgen werden, wobei die in ihm enthaltene Information lückenlos Auskunft über die Funktion eines in dem Flugkörper beispielsweise enthaltenen Zeitzünders gibt.According to the invention, an EEPROM memory serves as the flight recorder, into which a microprocessor writes the relevant information occurring during the flight of the missile in coded form. This memory can be recovered after the missile has been impacted or disassembled, the information contained in it providing complete information about the function of a time fuse contained in the missile, for example.

Flugschreiber an sich sind bei Flugzeugen bekannt und bestehen normalerweise aus einem Tonbandgerät in einer Flugschreiberbox, die so ausgebildet ist, daß sie auch bei einem Absturz des Flugzeuges in jedem Fall geborgen werden kann.Flight recorders per se are known in aircraft and usually consist of a tape recorder in a flight recorder box, which is designed in such a way that it can be recovered even if the plane crashes.

Anhand der einzigen Figur der beiliegenden Zeichnung sei im folgenden die Erfindung näher beschrieben.Based on the single figure of the accompanying drawing, the invention will be described in more detail below.

Bei einer mit einem Zeitzünder versehenen Rakete ergeben sich verschiedene relevante Informationen während des Fluges, die einem Mikroprozessor 10 zugeführt werden bzw. aufgrund von Steuerfunktionen gewonnen werden, die der Mikroprozessor 10 erzeugt. So wird beispielsweise erst beim Abschuß der Rakete eine Batterie aktiviert und es wird deren Hochlaufphase überwacht, indem ein Analog/Digital-Wandler 12 einen entsprechenden digitalen Wert dem Mikroprozessor 10 zuführt. Aus dieser hochlaufenden Batteriespannung wird beispielsweise über einen Sperrwandler eine geregelte Versorgungsspannung gewonnen, deren Wert ebenfalls nach Digitalisierung durch den Analog/Digital-Wandler 12 dem Mikroprozessor 10 zugeführt wird. Ferner werden die Zündkreise einer Explosivladung an Spannung gelegt, um beispielsweise beim Aufschlag der Rakete oder nach Ablauf einer bestimmten Verzögerungszeit durch Schließen entsprechender Schalter gezündet zu werden. Auch diese Zündspannung wird gemessen und nach Analog/Digital-Wandlung in dem Wandler 12 dem Mikroprozessor 10 zugeführt.In the case of a rocket provided with a time detonator, various relevant information results during the flight which are fed to a microprocessor 10 or are obtained on the basis of control functions which the microprocessor 10 generates. For example, a battery is only activated when the rocket is launched and its startup phase is monitored by an analog / digital converter 12 supplying a corresponding digital value to the microprocessor 10. From this ramp-up battery voltage, for example, a regulated supply voltage is obtained via a flyback converter, the value of which is also supplied to the microprocessor 10 after digitization by the analog / digital converter 12. Furthermore, the ignition circuits of an explosive charge are energized in order to be ignited, for example, when the rocket strikes or after a certain delay time has elapsed, by closing corresponding switches. This ignition voltage is also measured and is fed to the microprocessor 10 after the analog / digital conversion in the converter 12.

Die gemessene Zündertemperatur, die Stellung des Rotors einer mechanischen Sicherungseinrichtung und eine beispielsweise durch einen Oszillator und einen Zähler vorgegebene Zeitinformation werden über eine Treiberstufe 14 ebenfalls dem Mikroprozessor 10 zugeführt.The measured detonator temperature, the position of the rotor of a mechanical safety device and time information, for example predetermined by an oscillator and a counter, are likewise fed to the microprocessor 10 via a driver stage 14.

Beim vorliegen einer bestimmten Konstellation dieser erfaßten Werte und z.B. aufgrund einer in nicht näher dargestellter Weise einprogrammierten Verzögerungszeit erzeugt der Mikroprozessor 10 bestimmte Steuerfunktionen, wie z.B. einen Vorentsicherungsimpuls und einen Zündimpuls. Diese Impulse werden über Komparatoren 16, 16′ ebenfalls dem Mikroprozessor 10 zugeführt.If there is a certain constellation of these recorded values and e.g. Due to a delay time programmed in a manner not shown, the microprocessor 10 generates certain control functions, such as a pre-unlocking pulse and an ignition pulse. These pulses are also fed to the microprocessor 10 via comparators 16, 16 '.

Alle diese Informationen werden durch den Mikroprozessor 10 in codierter Form in einem Speicher EEPROM-18 abgespeichert. Dieser Speicher speichert auch bei Ausfall der Betriebsspannung die in ihm enthaltene Information und er kann auch nach dem Aufschlag oder der Zerlegung des Flugkörpers geborgen werden, wobei sein Inhalt ausgelesen werden kann und auf die verschiedenen Fragen Antwort gibt. Sein Inhalt gibt beispielsweise Auskunft darüber, ob die richtige Spannung an der Elektronik lag, ob die mechanische Sicherungseinrichtung bestimmte Schalter richtig geschlossen hat, ob der Rotor der Sicherungs­einrichtung von der Sicherstellung in die Scharfstellung gedreht hat, ob Spannungseinbrüche während der Flugphase zu verzeichnen waren, wie die Hochlaufphase der aktivierbaren Batterie aussah, wie der Ladezeitpunkt und Ladezustand der Zündkreise während des Fluges war, welche Temperaturen im Zünder während des Fluges geherrscht haben, zu welchem Zeitpunkt der Vorentsicherungsimpuls ausgegeben wurde, wann die Detonation erfolgte usw.All of this information is stored by the microprocessor 10 in coded form in a memory EEPROM-18. This memory stores the information contained in it even if the operating voltage fails and it can also be recovered after the missile has been impacted or disassembled, whereby its content can be read out and provides answers to the various questions. Its content provides information, for example, on whether the correct voltage was due to the electronics, whether the mechanical safety device has closed certain switches correctly, whether the rotor of the safety device has turned from the safety to the arming, or whether voltage dips were recorded during the flight phase, such as The start-up phase of the activatable battery looked like what the charging time and state of charge of the ignition circuits were during the flight, what temperatures existed in the igniter during the flight, at what time the pre-release pulse was issued, when the detonation occurred, etc.

Der vorhandene EEPROM-Speicher in Zusammenarbeit mit dem ebenfalls vorhandenen Mikroprozessor führt in vorteilhafter Weise zu der Integration eines "Flugschreibers", dessen Auswertung eine Information liefert, die sonst nur durch ein aufwendiges Telemetrie-Verfahren und umfangreiche Fehlerbeseitigungsprogramme erhalten werden kann.The existing EEPROM memory in cooperation with the microprocessor, which is also present, advantageously leads to the integration of a "flight recorder", the evaluation of which supplies information that can otherwise only be obtained by a complex telemetry process and extensive error correction programs.
