Description
Verfahren und Gerät zum Entfernen von Schnee- und Eisdecken, insbesondere von Trag- und Leitflächen Auf Flugplätzen hat sich beim Winterflugbetrieb sehr häufig die Notwendigkeit ergeben, eine auf im Freien abgestellten Flugzeuigen beflndliiche Schnee- und Eisdecke möglichst schnell zu entfernen. Bisher hat mang hierfür entweder Geräte zum mechanischen Abkratzen dieser Schnee- und Eisdecke verwendet oder auch durch Innenbeheizung der Flügel usw. die Schneedecke zum Schmelzen zu bringen versucht. Auch das Anblasen der Schneedecke selbst mit angewärmter Luft, wie diese zum Aufheizen von kalten Flugmotoren verwendet wird, ist denkbar. Schließlich muß auch noch angenommen werden, daß das Übergießen der Schneedecke mit warmem Wasser, das in Eimern - usw. herbeigeholt wurde, versucht worden ist.Method and device for removing layers of snow and ice, in particular of wings and control surfaces On airfields during winter flight operations very often the need to inflate an aircraft parked in the open air Remove snow and ice cover as quickly as possible. So far, mang has either done this Devices for mechanical scraping off this snow and ice cover used or also tries to melt the snow cover by internal heating of the wings etc. Even blowing heated air onto the snow cover itself, like this to heat it up used by cold aircraft engines is conceivable. Finally, it must also be accepted that the dousing of the snow cover with warm water in buckets - etc. was fetched, has been tried.
Alle diese Mittel erfordern jedoch eine recht lange Zeit.However, all of these means require quite a long time.
Gemäß der Erfindung ist zur Verkürzung der Zeit, die zum Entfernen von Schnee:- und Eisdecken von metallischen Auflageflächen, insbesondere vom Trag- und Leitwerk und auch vom Rumpf, im Freien abgestellter Flugzeuge benötigt wird, vorgesehen, daß ein Warmwasserstrahl durch eine Breitstrahldüse als ebener Wasserfilm ausgespritzt wird. wobei die Fläche des Wasserfilms möglichst parallel zur Auflagefläche zwischen diese und die aufliegende Schnee- Imw. Reifdecke eindringt. Bei praktischen Versuchen hat sich ergeben, daß der Wasserfilm bei der besagten Anwendung wie ein Messer die Schneedecke von ihrer Auflage trennt, ohne dall es liotwendig wäre, die ganze Schneedecke zum Schmelzen zu bringen. Unterstützt wird diese Ablösung der Schneedecke dadurch, daß sich durch die metallene Auflagefläche die Wärme sehr schnell fortpflanzt und daß dadurch längs der ganzen Auflage der Schneedecke ein lokales Schmelzen eintritt. Infolge der meist vorhandenen Schräglage der metallenen Auflagefläche rutscht sehr bald die ganze durch das Verfahren gemäß der Erfindung von der Auflage. abgelöste Schneedecke ab.According to the invention is to reduce the time it takes to remove from snow: - and ice sheets from metallic contact surfaces, especially from the and tail unit and also from the fuselage of aircraft parked in the open air is required, provided that a jet of hot water through a wide jet nozzle as even water film is sprayed out. where the area of the water film is possible parallel to the supporting surface between this and the snow imw. Frost cover penetrates. In practical tests it has been found that the water film in the said application like a knife separates the snow cover from its support without because it would be necessary to melt the whole blanket of snow. Supports this detachment of the snow cover is caused by the metal contact surface the heat propagates very quickly and that along the entire length of the Local melting occurs. As a result of the mostly existing inclination the metal bearing surface very soon slips through the whole process of the invention of the edition. detached snow cover.
Unter einem Wasserfilm ist im vorliegenden Zusammenhang eine möglichst vollkommen zusammenhängende Haut oder Schicht von Wasser zu verstehen, nicht also ein aus lauter versprühten Einzelteilchen bestehender nebelartiger Strahl. Der gemäß der Erfindung zu bildende und zwischen die Schneedecke und ihre Auflage zu spritzende Wasserfilm läßt sich auch als Wasserschaufel oder Wasserfächer bezeichnen.In the present context, a water film is preferably one To understand perfectly coherent skin or layer of water, not that a fog-like jet consisting of nothing but sprayed individual particles. According to of the invention to be formed and to be sprayed between the snowpack and its support The water film can also be referred to as a water scoop or water fan.
Um das Verfahren gemäß der Erfindung auf weiträumigen Flugplätzen leicht durchführen zu können, ist gemäß einer Weiterbildung der Erfindung vorgesehen, daß ein Wassertank i und eine Wasserförderpumpe samt Brennkraftaniriebsmotor 3 zusammen mit einem Heizbrenner .4 und einem von diesen erhitzten Durchlauferhitzer 5 zur Anwärmung des Z@"assers, einem an diesen Erhitzer angeschlossenen in einer Breitstrahldüse 6 endigenden Schlauch 7 und einem Brennstofftank 8 auf einem gemeinsamen Rahmen 9 trag- oder fahrbar angeordnet sind. Zweckmäßig wird über eine. Wassermangelsicherung io und einen im Warmwasser eingebauten Thermostat i i bei Stillstand des Motors 3 oder Erreichen der Höchsttemperatur der Brenner d ausgeschaltet, damit ein Überhitzen des E@`asservorrats vermieden wird. Mit dein Fahrzeug fährt nian, sobald sich die -Notwendigkeit zum Startklarinachen von verschneiten Flugzeugen ergibt, bis unmittelbar an das Flugzeug heran, setzt die Pumpe 2 mit dem kleinen BrennliraftillOtor 3 in Betrieb und erwärmt dabei das von der Pumpe geförderte Wasser im Durchlauferhitzer 3. Der Schlauch ; gestattet. das erzeugte Warmwasser unmittelbar als Wasserfächer 1a an die @-ertvendun@sstelle heranzuführen.In order to be able to easily carry out the method according to the invention on spacious airfields, a further development of the invention provides that a water tank i and a water feed pump including an internal combustion engine 3 together with a heating burner 4 and a water heater 5 heated by these for heating the Z @ "water, a hose 7 that ends in a wide-jet nozzle 6 and a fuel tank 8 are arranged on a common frame 9 in a portable or mobile manner or when the maximum temperature is reached, the burner is switched off to avoid overheating of the water supply. Your vehicle will not drive as soon as it is necessary to clear snow-covered planes to take off, the pump 2 will also start moving the small BrennliraftillOtor 3 in Betr ieb and heats the water delivered by the pump in the flow heater 3. The hose; allowed. to bring the hot water produced directly to the @ -ertvendun @ sstelle as water fan 1a.
Es ist zweckmäßig, den Heizbrenner so auszugestalten, daß er mit demselben Brennstoff wie die Brennkraftmaseliirie. also aus demselben IBreunstofftanlc 8 betrieben «-erden kann.It is advisable to design the heating burner so that it can be used with the same Fuel like the internal combustion maseliirie. So operated from the same IBreunstofftanlc 8 «-Can earth.
