Description
Foreliggende oppfinnelse angår en fremgangs- The present invention relates to a process
måte for tanking av et helikopter eller lignende luftfartøy, way of refueling a helicopter or similar aircraft,
samt en anordning for utførelse av fremgangsmåten. as well as a device for carrying out the method.
Ved henting og levering av last-som er beregnet for å transporteres fra en plass til en annen ved hjelp av et helikopter, er det av forskjellige årsaker hensiktsmessig å la helikopteret innta en stillestående stilling i luften (hovring) mens lasten forbindes med resp. fjernes fra en fra helikopteret nedhengende krok. When picking up and delivering cargo, which is intended to be transported from one place to another by means of a helicopter, it is appropriate for various reasons to let the helicopter take a stationary position in the air (hovering) while the cargo is connected to resp. removed from a hook hanging from the helicopter.
Dersom transportstrekningen er relativt kort If the transport distance is relatively short
og helikopteret gjentatte ganger henter og avleverer gods uten at det tas ned til bakken og tankes, er det lett å forstå and the helicopter repeatedly picks up and delivers cargo without it being brought down to the ground and refueled, it is easy to understand
at helikoptertanken må inneholde en stor mengde brensel før den første transporten påbegynnes. En stor brenselmengde i tankene betyr at helikopteret blir tungt, noe som ugunstig påvirker lastekapasiteten. that the helicopter tank must contain a large amount of fuel before the first transport begins. A large amount of fuel in the tanks means that the helicopter becomes heavy, which adversely affects the cargo capacity.
Por å rette på dette problem kan naturligvis helikoptertanken fylles bare delvis med brensel og helikopteret kan tankes hver gang gods hentes eller leveres, hvorved den påfylte brenselmengden tilpasses slik at den forbrukes under en transport. En slik tanking er imidlertid vanskelig å utføre mens helikopteret befinner seg i luften, eftersom- avstanden mellom helikopterets brenselspåfyllingsstuss og bakken ofte er stor, (avhengig av lastens og opphengningsanordningens vertikale utstrekning) og tar dessuten lang tid. To remedy this problem, the helicopter tank can of course only be partially filled with fuel and the helicopter can be refueled every time goods are picked up or delivered, whereby the amount of fuel filled is adapted so that it is consumed during a transport. However, such refueling is difficult to carry out while the helicopter is in the air, since the distance between the helicopter's fuel filler neck and the ground is often large (depending on the vertical extent of the load and the suspension device) and also takes a long time.
Det er en hensikt med foreliggende oppfinnelse That is one purpose of the present invention
å i det minste delvis eliminere ulempene med tidligere kjente fremgangsmåter og anordninger og å fremskaffe en fremgangsmåte og en anordning som tillater at helikopterets nyttelast- to at least partially eliminate the disadvantages of previously known methods and devices and to provide a method and a device that allows the helicopter's payload-
kapasitet øker og at tanking av helikopteret kan utføres mens capacity increases and that refueling of the helicopter can be carried out while
det befinner seg i luften. it is in the air.
Dette oppnås ved at oppfinnelsen får de i patentkravene angitte kjennetegn. This is achieved by the invention having the characteristics stated in the patent claims.
En foretrukket ut førelsesform ifølge oppfinnelsen skal beskrives nærmere i forbindelse med tegningen, der A preferred embodiment according to the invention shall be described in more detail in connection with the drawing, there
figur 1 er et skjematisk sideriss av et flyvende helikopter med last, til hvilken det er festet en brenseltank som benyttes ved fremgangsmåten ifølge oppfinnelsen, og figure 1 is a schematic side view of a flying helicopter with cargo, to which a fuel tank is attached which is used in the method according to the invention, and
figur 2 er en i flyretningen bakfra sett perspektivskisse av lasten og brenseltanken ifølge figur 1. figure 2 is a perspective sketch of the load and fuel tank according to figure 1, seen in the direction of flight from the rear.
Figur 1 viser et helikopter 1 ved hvis under-side det er festet en wire 2 med en krok 3- Kroken 3 bærer løstagbart en last i form av en med et spredeaggregat 4 forsynt gjødselmiddelbeholder 5, som eksempelvis kan være av den art som er vist i den svenske patentansøkning nr. 740509^-9. Gjødselmiddelbeholderen 5» som også er forsynt med to i flyretningen skrått bakoverrettede stabiliseringsvinger 6 og 7, Figure 1 shows a helicopter 1 at the underside of which is attached a wire 2 with a hook 3 - The hook 3 detachably carries a load in the form of a fertilizer container 5 equipped with a spreading unit 4, which can for example be of the type shown in the Swedish patent application no. 740509^-9. The fertilizer container 5", which is also provided with two stabilizing wings 6 and 7, slanted backwards in the direction of flight,
og en motor 8 for drift av aggregatet 4, inneholder gjødsel som under flyvningen spres over et på forhånd bestemt markom-råde. Når beholderen 5 er tømt for gjødsel flyr piloten helikopteret 1 til en stasjon, eventuelt av den art som er vist i svensk utlegningsskrift nr. 7502050-35 der den tomme beholderen settes ned og manuelt frakoples kroken 3- Også en med en hurtigkopling forsynt elektrisk kabel (ikke vist) som viderebefordrer signaler fra piloten til motoren 8 for igang-setting av spredeaggregatet 4, når helikopteret flyr over det bestemte markområdet, fjernes manuelt fra motoren. and a motor 8 for operating the aggregate 4, contains fertilizer which, during the flight, is spread over a predetermined ground area. When the container 5 has been emptied of fertiliser, the pilot flies the helicopter 1 to a station, possibly of the type shown in Swedish design document no. 7502050-35 where the empty container is set down and the hook 3 is manually disconnected - Also an electric cable fitted with a quick connector (not shown) which relays signals from the pilot to the engine 8 for starting the spreading unit 4, when the helicopter flies over the determined field area, is manually removed from the engine.
Ifølge oppfinnelsen er en brenseltank 9 løs-tagbart eller permanent festet på beholderens 5 bakside mellom vingene 6 og 7• Tanken 9 er forsynt med en innløps-/utløps-stuss 10 som danner hunnelementet i en hurtigkopling. I til-slutning til at den tomme beholderen 5 settes ned på stasjonen, utløses manuelt hurtigkoplingen mellom hunnelementet 10 og et hanelement 11, som er forbundet med den ene enden av en bøyelig slange 12, hvis andre ende er tilkoplet helikopterets 1 brenseltank (ikke vist) over et brenselfilter 13- According to the invention, a fuel tank 9 is detachably or permanently attached to the rear of the container 5 between the wings 6 and 7 • The tank 9 is provided with an inlet/outlet connection 10 which forms the female element in a quick coupling. In connection with the empty container 5 being set down on the station, the quick coupling between the female element 10 and a male element 11, which is connected to one end of a flexible hose 12, the other end of which is connected to the helicopter's 1 fuel tank (not shown), is manually triggered ) over a fuel filter 13-
Efter at alle mellom helikopteret 1 og beholderen 5 resp. tanken 9 tilkoplede ledninger og slanger er koplet f ra.,-~f-l-ys helikopteret fremover et stykke langs stasjonen der den hovrer over en med gjødsel fylt andre beholder, som er identisk med beholderen 5 og på hvilken en med brensel fylt andre tank, som er identisk med tanken 9, er løstagbart eller permanent festet. Den andre tanken 9 er av bakkepersonellet fylt med brensel og den andre beholderen 5 er fylt med gjødsel i løpet av helikopterets foregående tur. Påfyllingen av brensel til den andre .tanken 9 skjer ved at det til hunnelementet 10 manuelt tilkoples et hanelement 15 som er identisk med hanelementet 11, og som er forbundet med en slange som igjen er forbundet med et ikke vist brenselforråd over en,brenselpumpe 16. En ventil 14 i.eller mellom stussen 10 og tanken 9 sikrer at brensel ikke utmates fra tanken 9 når tankingen avsluttes og koplingen 10,15 utløses. After everyone between the helicopter 1 and the container 5 resp. the lines and hoses connected to the tank 9 are connected from ra.,-~f-l-ys the helicopter forward a distance along the station where it hovers over a second container filled with fertiliser, which is identical to the container 5 and on which a second tank filled with fuel, which is identical to the tank 9, is removable or permanently attached. The second tank 9 is filled with fuel by the ground personnel and the second container 5 is filled with fertilizer during the helicopter's previous trip. The filling of fuel to the second tank 9 takes place by manually connecting to the female element 10 a male element 15 which is identical to the male element 11, and which is connected with a hose which is again connected to a fuel supply, not shown, via a fuel pump 16. A valve 14 in.or between the spigot 10 and the tank 9 ensures that fuel is not discharged from the tank 9 when refueling ends and the coupling 10,15 is released.
Når helikopteret 1 hovrer over den andre fylte beholderen 5 med fylt brenseltank 9, koples beholderen sammen med kroken 3, hanelementet 11 koples sammen med hunnelementet 10 og den ovenfor nevnte elektriske.kabelen koples sammen med motoren 8. Så snart disse sammenkoplingene er utført kan helikopteret 1 lette og en pumpe 17 som er anordnet i nærheten av helikoptertanken og tilkoplet slangen 12, startes. Pumpen 17 suger brensel fra den nylig fylte brenseltanken 9, slik at brensel innmates i helikoptertanken via filteret 13- I stedet for å anordne en pumpe i nærheten av helikoptertanken kan pumpen festes på beholderen 5 eller på tanken 9 og da utgjøres av en trykkpumpe. Pumpen kan være elektrisk eller hydraulisk drevet og kan, om den er festet på beholderen 5 eller tanken 9 drives av motoren 8 eller av spredeaggregatet 4. I tilfelle at pumpen drives av motoren 8 eller spredeaggregatet 4, When the helicopter 1 hovers over the second filled container 5 with filled fuel tank 9, the container is connected to the hook 3, the male element 11 is connected to the female element 10 and the above-mentioned electric cable is connected to the motor 8. As soon as these connections are made, the helicopter can 1 light and a pump 17 which is arranged near the helicopter tank and connected to the hose 12, is started. The pump 17 sucks fuel from the recently filled fuel tank 9, so that fuel is fed into the helicopter tank via the filter 13- Instead of arranging a pump near the helicopter tank, the pump can be fixed on the container 5 or on the tank 9 and then be made up of a pressure pump. The pump can be electrically or hydraulically driven and, if it is fixed on the container 5 or the tank 9, can be driven by the motor 8 or by the spreader unit 4. In the event that the pump is driven by the motor 8 or the spreader unit 4,
pumpes brensel inn i helikoptertanken først når spredeaggregatet 4 begynner å arbeide. I stedet for å mate inn brenselet i helikoptertanken kan brenselet innmates direkte til helikopterets drivmotor, dersom dette finnes å være hensiktsmessig, og i stedet for å benytte en pumpe så kan brenselet på annen måte trykkes eller suges opp til helikopteret. fuel is pumped into the helicopter tank only when the spreading unit 4 starts working. Instead of feeding the fuel into the helicopter tank, the fuel can be fed directly to the helicopter's drive engine, if this is found to be appropriate, and instead of using a pump, the fuel can be pressurized or sucked up to the helicopter in another way.
Efter at gjødslingen og tankingen- er utført flys helikopteret tilbake til stasjonen for å avlevere den tomme-"" : beholderen og hente en ny beholder med brenseltank, som av' bakkepersonalet under gjødslingen er påfylt gjødning resp. After the fertilizing and refueling have been carried out, the helicopter is flown back to the station to hand over the empty container and pick up a new container with a fuel tank, which is filled with fertilizer or
brensel. fuel.
Dersom beholderen 5 av en eller annen årsak må droppes under flyvingen, kan wirens 2 feste til helikopteret 1 løsnes ved en impuls fra piloten. Ved droppingen brister en brytkopling 18 som kopler sammen endene på den av to deler bestående slange 12. If, for one reason or another, the container 5 has to be dropped under the wing, the wire 2 can be attached to the helicopter 1 by an impulse from the pilot. During the dropping, a break coupling 18 that connects the ends of the two-part hose 12 breaks.
Det innses klart at man sparer tid og lastekapasiteten øker ved å utnytte fremgangsmåten ifølge oppfinnelsen. Således medgår det minimal tid for bytte av gjødsel-beholder, eftersom samtlige tilkoplinger mellom helikopteret 1 It is clearly realized that time is saved and the loading capacity is increased by utilizing the method according to the invention. Thus, minimal time is required for changing the fertilizer container, since all connections between the helicopter 1
og beholderen 5 resp. brenseltanken 9 utføres i forbindelse med beholderbyttet. Ved at helikoptertanken alltid inneholder en liten mengde brensel og bare fylles med en mengde brensel som medgår under en gjødslingssyklus, kan beholderen gjøres større og mengden gjødning i denne øke, noe som minsker kostnadene for gjødslingsarbeidet. and the container 5 or the fuel tank 9 is carried out in connection with the container change. By the fact that the helicopter tank always contains a small amount of fuel and is only filled with an amount of fuel that is included during a fertilization cycle, the container can be made larger and the amount of fertilizer in it increased, which reduces the costs of the fertilization work.
Oppfinnelsen er naturligvis ikke begrenset til The invention is of course not limited to
den ovenfor beskrevne og på tegningen viste utførelsesform, the embodiment described above and shown in the drawing,
men man kan tenke seg andre tillempninger og flere modifikasjoner innen rammen for oppfinnelsen. Således kan fremgangsmåten tillempes når som helst når et helikopter eller et lignende luftfartøy skal utføre flere transporter i løpet av den tid det tar å tømme helikoptertanken for brensel. Eksempler på but one can imagine other adaptations and more modifications within the scope of the invention. Thus, the method can be applied at any time when a helicopter or a similar aircraft is to carry out several transports during the time it takes to empty the helicopter tank of fuel. Examples of
andre bruksområder enn den ovenfor beskrevne er transport av med betong fylte beholdere mellom en påfyllingsstasjon og en byggeplass, hvorved betongen utmates fra beholderne ved byggeplassen mens helikopteret hovrer. Helikopteret vender tilbake til stasjonen med den tomme beholderen og bytter denne mot en annen med betong fylt beholder. Den brenselstanken som er permanent eller løstagbart festet til betongbeholderen, areas of use other than the one described above are the transport of containers filled with concrete between a filling station and a construction site, whereby the concrete is discharged from the containers at the construction site while the helicopter hovers. The helicopter returns to the station with the empty container and exchanges it for another container filled with concrete. The fuel tank which is permanently or removably attached to the concrete container,
eller lpstagbart festet til helikopteret, påfylles og tømmes hensiktsmessig på den måte som ovenfor beskrevet i forbindelse med gjpdselmiddelbeholderen. Oppfinnelsen er således bare begrenset til det som er angitt i de etterfølgende patentkrav. or removable attached to the helicopter, is filled and emptied appropriately in the manner described above in connection with the fuel container. The invention is thus only limited to what is stated in the subsequent patent claims.
