Abstract

This innovation alters the pressure in the high and low pressure areas in the air stream over a moving vehicle. This is achieved with the aid of an air duct passing through the vehicle in which a drive motor is fitted to accelerate the air flow. The accelerated air flow serves to lessen the vehicle wind resistance thereby decreasing the amount of energy required to keep the vehicle moving. By appropriate design of the inlet and outlet openings of the duct the stability of the vehicle can be enhanced.

Veränderung des Luftwiderstandes bei Fahrzeugen durch Zwangsbelüftung. Bescheeibung : Stand der Technik Beim Transport von Personen und Lasten müssen Fahrzeuge den Luftwiderstand Oberwinden. Der dafür erforderliche Aufwand an Energie hängt insbesondere von der Form der Fahrzeugoberfläche ab. Der Herstellung anzustrebender windschlüpfriger Formen sind bisher enge Grenzen gesetzt. Bei der Mehrzahl der Fahrzeuge bleibt der entsprechende Widerstandswert daher weit über dem gewünschten Minimum. Aus der heutigen Sicht gesteigerten Energiebewußtseins muß man bedauern, daß bei den herkömmlichen Möglichkeiten der Gestaltung strömungsgünstiger Formen erhebliche Energien vergeudet werden.Change in air resistance in vehicles through forced ventilation. Description : State of the art When transporting people and loads, vehicles must have the Air resistance overhead winds. The amount of energy required for this depends in particular on the shape of the vehicle surface. The production of more streamlined ones to strive for Up to now, there are narrow limits to shapes. The majority of vehicles stay with the corresponding resistance value therefore well above the desired minimum. From today's View of heightened energy consciousness one has to regret that with the conventional Possibilities for the design of aerodynamic shapes wasted considerable energy will.

Darstellung der Neuerung An der Oberfläche des in Bewegung befindlichen Fahrzeuges werden mit Hilfe der Neuerung die Stau- und Sogbereiche der umgebenden Luft verändert. Dies geschieht durch eine Zwangsführung (A) des umgebenden Mediums durch das Fahrzeug hindurch. Dabei kann ein besonderer Antrieb zur Beschleunigung der Luft in der Zwangsführung eingesetzt werden (B). Bei geeigneter Wahl der Eintritts- und Austrittsöffnungen findet eine Minderung des Luftwiderstandes statt.Representation of the innovation on the surface of what is in motion With the help of the innovation, the storage and suction areas of the surrounding vehicle are removed Air changed. This is done by forced guidance (A) of the surrounding medium through the vehicle. A special drive can be used for acceleration the air can be used in the forced operation (B). With a suitable choice of entry and outlet openings there is a reduction in air resistance.

Auch zur Stabilisierung des Fahrvorganges kann beigetragen werden. Die bisherige Formgebung kann, diese Neuerung nutzend, mehr anderen Kriterien folgen.It can also help to stabilize the driving process. The previous design can, using this innovation, follow more different criteria.
