Abstract

The airscrew shroud doubling as a radiator is conventional in basic shape and profile. It is hollow, and it is embodied into the engine coolant circuit by way of its also hollow supporting struts. Both the inner and outer surfaces can be used for releasing heat. Flow through the shroud is pref. along two parallel paths each covering one half. The curved inside and outside surfaces of the shroud give sufficient heat exchange area while maintaining an efficient aerodynamic shape. The system ensures that the shrouds and struts are protected against icing up while flying through supercooled clouds.

Description

Bezeichnung: SantelscEAraubenkühlerDesignation: SantelscE screw cooler

Es handelt sich hier um einen sogenannten Oberflächenkühler in Form einer Mantelschraube. Dabei wird das zu kühlende Medium durch den Mantel eines Luftschrauben-oder Fan-Antriebs geleitet und durch den vom Fan Deschleunigten Luftstrom gekühlt. Es kennen dabei sowohl die Innen- als auch die Äusserflächen des mantels als wärmeabführende Oberflächen verwendet werden (siehe Skizze).This is a so-called surface cooler in the form a jacket screw. The medium to be cooled is thereby through the jacket of a propeller or Fan drive and cooled by the air flow accelerated by the fan. It know both the inner and outer surfaces of the jacket as heat dissipating Surfaces can be used (see sketch).

Die Vorteile dieser Anordnung im Vergleich zur Kühlung durch einen herköLmlichen kühler sind: - sofort einsetzende Lühlwirkung nach dem Anlassen des Triebwerkes - kein zusatzlicher Luftwiderstand - keine zusätzliche Führung der Kühlluft Vorteile im Vergleich zur Kühlung durch einen anderen Oberflächenkühler: - beidseitige Umströmung des I.antelschrauDenkühlers - sinnvolle Nutzung des BFantels, der im Gegensatz zur Rumpfoberfläche nicht anderweitig benutzt werden kann Durch die Verwendung dieses Kühlers kann man bei Luftfahrzeugen, die mit einer r.antelschraube ausgerüstet sind, langlebige und leise Verbrennungsmotoren einsetzen, wobei durch das Wegfallen des Luftwiderstandes der Einläufe für luftgekühlte Verbrennungsmotoren eine Leistungsverbesserung in der Grössenordnung von 10% zu erwarten ist.The advantages of this arrangement compared to cooling by a Conventional coolers are: - The cooling effect starts immediately after the Engine - no additional air resistance - no additional guidance of the cooling air Advantages compared to cooling with another surface cooler: - on both sides Flow around the I-jacket screw cooler - sensible use of the B-jacket, which is in the In contrast to the fuselage surface, it cannot be used otherwise by using This cooler can be used on aircraft that are equipped with a screw jack are to use long-lasting and quiet internal combustion engines, whereby by eliminating the air resistance of the inlets for air-cooled internal combustion engines an improvement in performance in the order of magnitude of 10% is to be expected.
