Description
Die Erfindung bezieht sich auf ein mindestens ein-Manntragendes Wasserfahrzeug, mit dem es möglich ist, mit wenig Energiezufuhr gut kontrollierbar und schnell durch das Wasser zu fahren.The invention relates to an at least one man carrying watercraft, with which it is possible to drive well with little energy and fast through the water.
STAND DER TECHNIKSTATE OF THE ART
Bei ein-Mann-tragenden Wasserfahrzeugen werden als Antrieb Segel, Paradrachen, Muskelkraft, Verbrennungs- oder Elektromotoren verwendet. Meistens werden Schwimmplattformen mit oben genannten Antrieben gewählt. Die erzielbare Geschwindigkeit ergibt sich durch die Antriebsart und den verwendeten Schwimmkörper, wodurch sich physikalische Grenzen ergeben. Eine entscheidende Verbesserung wurde gefunden, z. B. durch Verwendung von Tragflächen, die den Schwimmkörper durch deren Ca-Flächenströmungsauftrieb aus dem Wasser tragen und so den Cw-Strömungswiderstand des Schwimmkörpers zum großen Teil eliminieren. Da die Stirnflächen der Tragfläche verhältnismäßig deutlich kleiner sind, ergibt sich daraus ein deutlich kleinerer Cw-Wert, wodurch bei gleicher zugeführter Antriebsenergie ein Vielfaches an Vortriebsgeschwindigkeit resultiert.In one-man carrying watercraft are used as a drive sail, parade, muscle power, combustion or electric motors. Mostly swimming platforms are chosen with the above drives. The achievable speed results from the type of drive and the float used, which results in physical limits. A decisive improvement was found, for. B. by using wings that carry the float through the Ca surface flow from the flow of water and so eliminate the Cw flow resistance of the float to a large extent. Since the end faces of the wing are relatively much smaller, this results in a much smaller Cw value, resulting in a multiple of propulsion speed with the same supplied drive energy.

NACHTEILE:DISADVANTAGE:
Als anwendungskritisch ergab sich die Längsauftriebsrichtungsstabilität zu halten. Da der Bereich der Anstellwinkel nur wenige Winkelgrade sind, führt ein entsprechend größerer Wellengang zu großen Flächenausschlägen. Als Ergebnis führt das zum Auftauchen des Canardflügels an die Wasseroberfläche und beim Wiedereintritt unter die Wasseroberfläche werden Luftblasen an der Canardfläche gebildet, die dann eine Zeit erhalten bleiben.As application critical, the longitudinal buoyancy direction stability was maintained. Since the range of angles of attack are only a few degrees, a correspondingly larger swell results in large surface rashes. As a result, the surface of the canard wing is exposed to the surface of the water and upon re-entry below the water surface, air bubbles are formed on the canard surface, which are then retained for a time.
Die Folge ist, dass der Canardflügel keinen Auftrieb erzeugt und die Konstruktion abstürzt, sodass der Startvorgang wiederholt wird, was zu einer pumpenden Fahrt führt.The result is that the canard wing does not generate lift and the structure crashes, repeating the startup process, resulting in a pumping ride.
Bei den bekannten Konstruktionen ist nahezu keine akzeptable Kurvenfahrt und Geradeausfahrt möglich, da die Konstruktionen überwiegend mit dem Canardflügelauftrieb durch Links- oder Rechtsdrehungen für die Richtung kontrolliert werden. Der Canardflügel kann wie oben beschrieben bei einer Luftblasenbildung mangels Auftrieb keine Kurve einleiten.In the known constructions almost no acceptable cornering and straight ahead driving is possible because the constructions are controlled predominantly with the Canardflügelauftrieb by left or right turns for the direction. As described above, the canard wing can not initiate a curve due to a lack of buoyancy.
Da die oben beschriebenen Antriebe, wie beispielsweise Elektromotoren, immer in einem Gehäuse montiert und vor dem umströmenden Wasser hermetisch abgedichtet werden müssen, jedoch andererseits mit dem umgebenden Wasser gekühlt werden müssen, ist ein hoher mechanischer Aufwand erforderlich. Die Fehlerquellen und Herstellungskosten sind dadurch relativ hoch.Since the drives described above, such as electric motors, must always be mounted in a housing and hermetically sealed in front of the circulating water, but on the other hand must be cooled with the surrounding water, a high mechanical complexity is required. The sources of error and manufacturing costs are relatively high.
DIE VORLIEGENDE ERFINDUNG HAT ZUR AUFGABE:THE PRESENT INVENTION HAS THE TASK:
- – ein Tragflächenwasserfahrzeug zu realisieren, das in jedem Fahrtzustand voll kontrollierbares Steuern ermöglicht- To realize a hydrofoil that allows fully controllable control in each state
- – dass eine Luftabsaugvorrichtung realisiert ist zur Verhinderung von Luftblasenbildung an den Stabilisierungsflächen- That an air suction device is realized to prevent the formation of air bubbles on the stabilizing surfaces
- – dass eine einfache Handhabung und Herstellung der Antriebseinheit mit optimaler Wasserkühlung ermöglicht ist- That easy handling and production of the drive unit with optimum water cooling is possible

Die Haupttragfläche
Erklärung:
Um die Trägheit einer hochgestreckten Tragfläche um die Längsachse zu verbessern, wird die Wendigkeit durch eine aktive Rudersteuerung erhöht. Der negative V-Form-Winkel der Tragfläche erzeugt eine zusätzliche Instabilität, die diesen Effekt unterstützt. Bei einer aktiven Tragflächensteuerung mit Ruder entsteht ein negatives Wendemoment, welchem durch eine 100%ige Ausschlagsdifferenzierung entgegengewirkt wird, bei der nur das kurveninnere Ruder den kurveneinleitenden Ruderausschlag generiert. Um bei entsprechenden Fahrmanövern eine Aufrechterhaltung einer Luftblasenbildung zu vermeiden, ist erfindungsgemäß an der Steuerungsfläche
Statement:
In order to improve the inertia of an upraised wing about the longitudinal axis, the maneuverability is increased by an active rudder control. The negative V-shape angle of the wing creates additional instability that supports this effect. In an active wing control with rudder creates a negative turning moment, which is counteracted by a 100% deflection differentiation, in which only the inside of the rudder generates the curve-initiating rudder deflection. In order to avoid the maintenance of an air bubble formation during corresponding driving maneuvers, according to the invention on the control surface
Demzufolge bleibt die Wasserströmung ungestört erhalten, was eine gute Manövrierfähigkeit ermöglicht.As a result, the water flow is maintained undisturbed, allowing good maneuverability.
