Description
Foreliggende oppfinnelse angår et flylegeme som angitt i den innledende del av patentkrav 1. The present invention relates to an aircraft body as stated in the introductory part of patent claim 1.
Visse flylegemer, som for eksempel raketter og prosjektiler, er som regel forsynt med en fenghette, hvor det i tilfelle feilfunksjon, men også for funksjonsanvisning er av interesse å vite hvorfor det foreligger en feilfunksjon eller hvilke årsaker som utløste funksjonen. For å bringe dette på det rene blir det, spesielt for utprøvning og feilanalyse, bygget telemetri-raketter, henholdsvis prosjektiler, som overforer flydata til en jordstasjon over tilsvarende antenner og en radio-forbindelse, slik at man ved hjelp av kompliserte måleserier kan få kjennskap til årsakene til en feilfunksjon, henholdsvis funksjonen. Disse undersøkelser er alltid svært dyre og krever meget store anstrengelser for bearbeidelse og modifikasjon av flylegemene. Feilrettingsprogrammer forårsaker enorme omkostninger og forsinker seriefremstilling av produktene. Plutselig opptredende feil ved avfyring kan bare vanskelig bli lokalisert og fører til stopp av hele produksjoner. Certain aircraft, such as rockets and projectiles, are usually equipped with a catch cap, where in the event of a malfunction, but also for functional instructions, it is of interest to know why there is a malfunction or what causes triggered the function. To bring this to light, telemetry rockets, respectively projectiles, are built, especially for testing and error analysis, which transmit flight data to a ground station via corresponding antennas and a radio connection, so that with the help of complicated measurement series one can gain knowledge to the causes of a malfunction, respectively the function. These investigations are always very expensive and require a great deal of effort for the processing and modification of the aircraft bodies. Debug programs cause enormous costs and delay mass production of the products. Sudden errors during firing can be difficult to localize and lead to the stoppage of entire productions.
Det er derfor en oppgave for foreliggende oppfinnelse å fremskaffe ét flylegeme av den art som ble nevnt innledningsvis, hvilket flylegeme på en praktisk måte blir utstyrt med en ferdsskriver, bare med en ubetydelig modifikasjon. Denne oppgave har det lykkes å løse ved hjelp av karakteristikken i patentkravet. It is therefore a task for the present invention to provide an aircraft body of the kind mentioned at the outset, which aircraft body is equipped in a practical way with a trip recorder, only with an insignificant modification. This task has been successfully solved with the help of the characteristic in the patent claim.
Ifølge oppfinnelsen tjener et EEPROM-lager som ferdsskriver, i hvilket lager en mikroprosessor innskriver de relevante informasjoner som opptrer under flylegemets ferd i kodet form. Dette lager kan etter nedstyrtning eller ødeleggelse av flylegemet bli berget, slik at informasjonene i dette uten mangler kan gi opplysninger for eksempel om en tidsinnstilt fenghette i flylegemet. According to the invention, an EEPROM storage serves as a trip recorder, in which storage a microprocessor records the relevant information that occurs during the flight of the fuselage in coded form. This warehouse can be salvaged after the crash or destruction of the fuselage, so that the information in it can provide information, for example, about a timed trap cap in the fuselage without any deficiencies.
I fly er ferdsskrivere i og for seg kjent, og består vanligvis av en lydbåndopptaker i en ferdsskriverboks som er utformet slik at den også ved flystyrt alltid kan berges. In aircraft, tachographs are known in and of themselves, and usually consist of an audio tape recorder in a tachograph box which is designed so that it can always be saved even when the aircraft is in flight.
Under henvisning til den eneste figur på vedlagte tegning skal oppfinnelsen i det følgende beskrives nærmere. With reference to the only figure in the attached drawing, the invention will be described in more detail below.
I en rakett som er forsynt med en tids-fenghette, fremkommer under ferden forskjellige relevante informasjoner, hvilke informasjoner blir tilført en mikroprosessor 10, henholdsvis blir oppnådd på grunn av styrefunksjoner som mikroprosessoren 10 utfører. Således blir for eksempel ved avfyring av raketten først et batteri aktivert og dettes spennings-stigningsfase blir overvåket, idet en analog/digital-omformer 12 tilfører mikroprosessoren en tilsvarende digital verdi. Fra denne stigende batterispenning erholdes for eksempel over en sperreomformer en regulert forsyningsspenning, hvis verdi på samme måte blir tilført mikroprosessoren 10 etter digitalisering ved hjelp av analog/digital-omformeren 12. Videre blir tennkretsene til en eksplosivladning tilført spenning, for for eksempel ved anslag av raketten eller etter utløpet av en bestemt tidsforsinkelse å bli tent ved lukking av en tilsvarende strømbryter. Også denne tennspenning blir målt og tilført mikroprosessoren 10 etter analog/digital-omforming i omformeren 12. In a rocket which is provided with a time capture cap, various relevant information appears during the journey, which information is supplied to a microprocessor 10, respectively is obtained due to control functions that the microprocessor 10 performs. Thus, for example, when the rocket is fired, a battery is first activated and its voltage rise phase is monitored, as an analogue/digital converter 12 supplies the microprocessor with a corresponding digital value. From this rising battery voltage, for example, a regulated supply voltage is obtained via a blocking converter, the value of which is supplied to the microprocessor 10 in the same way after digitization with the aid of the analogue/digital converter 12. Furthermore, the ignition circuits of an explosive charge are supplied with voltage, for example by the impact of the rocket or after the expiry of a certain time delay to be ignited by closing a corresponding power switch. This ignition voltage is also measured and supplied to the microprocessor 10 after analog/digital conversion in the converter 12.
Likeledes blir den målte fenghette-temperatur, rotor-stillingen til en mekanisk sikringsinnretning og en forutbestemt tidsinformasjon for eksempel fra en oscillator og en teller, tilført mikroprosessoren 10 over et drivtrinn 14. Likewise, the measured catch cap temperature, the rotor position of a mechanical safety device and predetermined time information, for example from an oscillator and a counter, are supplied to the microprocessor 10 via a drive stage 14.
Når det foreligger en bestemt konstellasjon av disse innhentede verdier og for eksempel på grunn av en innprogram-mert forsinkelsestid som ikke er nærmere beskrevet, utfører mikroprosessoren 10 bestemte styrefunksjoner, som f.eks. en for-avsikringsimpuls og en tennimpuls. Disse impulser blir også tilført mikroprosessoren 10 over komparatorene 16, 16'. When there is a certain constellation of these obtained values and, for example, due to a programmed delay time which is not described in more detail, the microprocessor 10 performs certain control functions, such as e.g. a pre-fuse pulse and an ignition pulse. These impulses are also supplied to the microprocessor 10 via the comparators 16, 16'.
Alle disse informasjoner blir lagret i kodet form i et EEPR0M-18-lager ved hjelp av mikroprosessoren 10. Dette lager beholder også de informasjoner det inneholder dersom drifts-spenningen faller ut, og det kan også ved anslag eller ødeleggelse av flylegemet bli reddet, slik at lagerets innhold kan bli tydet og gi svar på de forskjellige spørsmål. Innholdet gir for eksempel opplysning om hvorvidt elektronikken hadde riktig spenning, om den mekaniske sikringsinnretningen lukket bestemte brytere riktig, hvorvidt sikringsinnretningens rotor hadde dreiet fra sikringsstilling til skarpstilling, hvorvidt spenningsavbrudd under ferdsfasen var spesifisert, hvorledes oppstigningsfasen for det oppladbare batteri så ut, hvorledes tennkretsens ladetidspunkt og ladetilstand var under ferden, hvilke temperaturer som hersket under ferden i fenghetten, på hvilket tidspunkt for-avsikringsimpulsen ble utløst, når detonasjonen fant sted, osv. Det aktuelle EEPROM-lager i samarbeid med den aktuelle mikroprosessor fører på fordelaktig måte til integrasjon av en "ferdsskriver" hvis tydning gir informasjoner som ellers bare kan oppnås ved en omfattende telemetri-prosess og omfangsrike feilvurderingsprogrammer. All this information is stored in coded form in an EEPR0M-18 storage with the help of the microprocessor 10. This storage also retains the information it contains if the operating voltage drops out, and it can also be saved in the event of an impact or destruction of the fuselage, as that the warehouse's contents can be deciphered and provide answers to the various questions. The content provides, for example, information about whether the electronics had the correct voltage, whether the mechanical safety device closed certain switches correctly, whether the rotor of the safety device had turned from the safety position to the sharp position, whether a voltage interruption during the travel phase was specified, what the ascent phase of the rechargeable battery looked like, what the charging time of the ignition circuit was and state of charge was during the trip, what temperatures prevailed during the trip in the cap, at what time the pre-fuse impulse was triggered, when the detonation took place, etc. The relevant EEPROM storage in cooperation with the relevant microprocessor advantageously leads to the integration of a "journal recorder" whose interpretation provides information that can otherwise only be obtained through an extensive telemetry process and extensive fault assessment programs.
