Abstract

A para-glider is made from flexible material which is usually inflated to form an aerodynamic profile by the ram pressure of the air which flows into the internal compartments into which the paraglider is divided. The invention proposes a para-glider in which the internal compartments are sealed and are inflated with a gas under pressure before use. This proposal ensures that the correct aerodynamic form is maintained under all operational conditions and reduces the risks for the pilot. The internal compartments may be formed by flexible hoses. USE - Para-gliders.

Description

Die Erfindung betrifft ein Fluggerät aus flexiblem Material dessen aerodynamisches Profil (Auftriebsprofil) durch einen in Kammern erzeugbaren Staudruck gebildet wird, insbesondere Gleitschirm.The invention relates to an aircraft made of flexible material its aerodynamic profile (lift profile) by a back pressure which can be generated in chambers is formed, in particular Paraglider.

Auftriebserzeugende oder ein Fluggerät stabilisierende Flächen werden im allgemeinen aus starren Materialien oder aus starren Gerüsten mit flexibler Bespannung hergestellt. Eine Ausnahme bildet die Kappe eines Gleitschirms, deren Profil durch einen Staudruck aufgebaut wird und während des Fluges erhalten bleibt. Der Staudruck wird in Kammern erzeugt, die in Flug­ richtung offen sind.Surfaces that generate lift or stabilize an aircraft are generally made of rigid materials or rigid Scaffolds made with flexible covering. An exception forms the cap of a paraglider, whose profile through a Back pressure is built up and maintained during the flight remains. The dynamic pressure is generated in chambers that are in flight direction are open.

In kritischen Flugsituationen können sich die Kammern teil­ weise oder ganz entleeren, was eine Gefahr für den Piloten darstellt.The chambers can participate in critical flight situations wise or completely empty, which is a danger to the pilot represents.

Die an der angeströmten Kante des Auftriebsprofils, beispiels­ weise an der Schirmnase vorgesehenen Öffnungen der Kammern, lassen eine aerodynamisch optimale Ausformung der Vorderkante nicht zu.The on the inflated edge of the lift profile, for example openings of the chambers provided on the shield nose, leave an aerodynamically optimal shape of the front edge not to.

Aufgabe der Erfindung ist es, ein Fluggerät nach dem Gattungs­ begriff so auszubilden, daß kritische Flugsituationen und die damit für den Piloten einhergehenden Gefahren verringert und das aerodynamische Profil verbessert werden. Die erfindungsgemäße Lösung zeichnet sich durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale aus.The object of the invention is to provide an aircraft of the generic type understood to train so that critical flight situations and the  this reduces the dangers associated with the pilot and the aerodynamic profile can be improved. The Solution according to the invention is characterized by the in the license plate of claim 1 specified features.

Alle oder einige der Kammern werden zur Benutzung luftdicht ver­ schlossen und durch ein gasförmiges Medium mit Überdruck ge­ füllt. Das Füllen kann beispielsweise durch eine Hand- oder Fuß­ pumpe vorgenommen werden. Gegebenenfalls können in die üblicherweise mit Nähten versehenen Kammern geeignete luft­ dichte Schläuche oder der Form der Kammern angepaßte luftdichte Aufblasteile eingearbeitet sein. Vor dem Abbau (Zusammenlegen) des Fluggeräts kann die Luft beispielsweise durch ein Ventil wieder abgelassen werden.All or some of the chambers are airtight for use closed and ge through a gaseous medium with excess pressure fills. Filling can be done by hand or foot, for example pump can be made. If necessary, in the Suitable air, usually with sutures tight hoses or airtight to match the shape of the chambers Inflation parts must be incorporated. Before dismantling (folding) the aircraft can, for example, the air through a valve be drained again.

In weiterer Ausbildung der Erfindung wird vorgeschlagen, durch Aufpumpen beliebiger Hohlkörper, wie Tragflächen oder Stabili­ sierungsflächen an Fluggeräten, diese aerodynamisch zu formen bzw. zu stabilisieren.In a further embodiment of the invention, it is proposed Inflate any hollow body, such as wings or stabilizers areas on aircraft to shape them aerodynamically or to stabilize.

Bei einem erfindungsgemäß ausgebildeten Gleitschirm sind keine oder nur noch wenige Öffnungen an der Schirmvorderkante vor­ handen. Dadurch wird der Strömungswiderstand verringert. Ein seitliches Einklappen des Schirmes oder das Einklappen der Schirmvorderkante werden vermieden. Die Kammern können sich in kritischen Flugsituationen nicht entleeren. Es wird eine wesentlich erhöhte Sicherheit für den Piloten erreicht.In a paraglider designed according to the invention there are none or only a few openings on the front edge of the screen act. This reduces the flow resistance. A folding in the screen or folding in the The leading edge of the screen is avoided. The chambers can do not empty in critical flight situations. It will be one significantly increased safety for the pilot.

Bei anderen Fluggeräten, die nicht als Gleitschirme bezeichnet werden, kann eine hohe Formfestigkeit von als Hohlkörper aus­ gebildeten Flächen erreicht werden, wobei formgebende Starr­ elemente völlig entfallen können oder nur geringfügig einge­ setzt werden müssen.For other aircraft that are not referred to as paragliders can be a high dimensional stability of as a hollow body formed areas can be achieved, shaping rigid elements can be omitted completely or only slightly must be set.
