Description
Flugzeug. lm Flugzeugbau gilt der Grundsatz, daß der ärodvnamische Druckmittelpunkt mög-, liehst tief zu liegen hat.Plane. In aircraft construction, the principle applies that the aerodynamic Center of pressure as possible, has to lie low.
Solange. den Flugzeugrümpfen rechteckige Ouerschnittsform gegeben wurde, bereitete die. Erfüllung dieser Bedingung beim Bau von Doppel- und Mehrdeckern keine Schwierigkeiten, weil hierbei die unteren Flügel an die unteren Rumpfholme unmittelbar angeschlossen werden konnten, so daß aus der Tieflage der Flügel die Tieflegung des ärodvnainischen Druckmittelpunktes sich von selbst ergab.: Erhält dagegen der Rumpf rundlichen, d. h. kreisrunden, ellyptischen oder tropfenförmigen Querschnitt, so müssen die Längsholme einen größeren senkrechten Abstand von dem tiefsten Punkt des Rumpfes einnehmen, und um die Größe dieses Abstandes wird auch der ärodynainische Druclcmi@ttelptinkt höher verlegt, wenn bei dieser Rumpfform die lilü= gel in üblicher Weise unmittelbar .an die unteren Rumpfbohne angeschlossen werden.So long. given the fuselages a rectangular cross-sectional shape was prepared the. Fulfillment of this condition when building double and multi-deckers no difficulties because the lower wings are attached to the lower fuselage spars could be connected directly, so that from the lower position of the wing the Lowering of the Aerodvnainic center of pressure resulted by itself: Receives on the other hand, the trunk is rounded, d. H. circular, elliptical or teardrop-shaped Cross-section, the longitudinal spars must have a greater vertical distance from the occupy the deepest point of the torso, and by the size of this distance will also the aero-synchronic pressure tinker tinkers higher, if with this hull shape the lilü = gel directly connected to the lower trunk bean in the usual way will.
Durch Vermittlung von Streben lassen sich die unteren Flügel zwar in der erwünschten tiefen Anordnung zum Rumpf an den Längsbahnen befestigen, aber es erscheint doch erstrebenswert, diese Konstruktionsmittel auszuschalten, weil durch sie der Bau der Flugzeuge umständlicher und teurer wird und die 7ahl der Gefahrenduellen sich vergrößert.By arranging struts, the lower wings can be admittedly attach to the longitudinal panels in the desired deep arrangement to the fuselage, but it seems worth striving to switch off these constructional means because they make the construction of the aircraft more cumbersome and expensive and the number of dangerous duels enlarges.
Auf dem kürzesten, einfachsten ünd damit sichersten Wege läßt sieh die Befestigung der unteren Flügel in größerem, senkrechtem Abstande von den unteren Längsholmen des gerundeten Flugzeugrumpfes dadurch bewirken, (iaß innerhalb der Vertikalebene der Rumpfliolnie mit diesen fest verbundene Stege angebracht werden, die in der (Quer richturig gleichfalls durch Stege mit dem Rumpf bzw. dessen Spanten in starrer Verbindung stehen.In the shortest, simplest and therefore safest way, you can see the fastening of the lower wings at a larger, vertical distance from the lower ones Longitudinal spars of the rounded aircraft fuselage thereby cause (iaß within the The vertical plane of the fuselage is attached to these firmly connected webs, those in the (transversely correct also by webs with the fuselage or its frames are in rigid connection.
Diese -Längsstege bilden mit den Querstegen und Rumpf'spänten ein festes Gefüge; so daß a.': ihnen die Flügelgleich sicher befestigt «-erden können @ als an. den -h,äiigsholinen selbst.These -longitudinal bars form with the cross bars and fuselage spänten solid structure; so that a. ': the wings can be securely attached to them @ as an. the -h, äiigsholinen themselves.
Die Zeichnung: zeigt -in Querschnitt und Schaubild den Rumpfteil- eines Flugzeuges. -In der Ebene der unteren Längsholme (a) sind Stege (1i) angeordnet, die sich von unten her gegen die Längsholme (a) legen und durch Keilstücke (d) mit den Sparten (h) zii einem festen Gefüge verbunden sind. Auch die Spanten.(h) werden in - der Regel an der Anschlußstelle für die Flügel innen verstrebt, worauf in der Zeichnung-wegen der Einfachheit und Übersichtlichkeit keine-Rücksicht genommen worden .ist.The drawing: shows the fuselage part of an aircraft in a cross-section and a diagram. In the plane of the lower longitudinal spars (a) there are webs (1i) that lie against the longitudinal spars (a) from below and are connected to the sections (h) zii by means of wedges (d) with the sections (h) zii. . The ribs (h) are in - braced usually at the connection point for the wings inside, .is what was put into the drawing-because of the simplicity and clarity no-respect.
Dieser ganze für den Anschluß. der unteren Flügel dienende Gerüstteil wird von der Rumpfhaut so umkleidet, daß nur die Außenfläche jedes der beiden senkrechten Stege frei liegt, an--der mit den üblichen Mitteln die Befestigung der Flügel erfolgt.This whole for the connection. the lower wing serving the framework part is covered by the skin of the fuselage in such a way that only the outer surface of each of the two is vertical Webs is exposed, on - the attachment of the wings is done with the usual means.
