De oude Egyptenaren waren al aan het puzzelen. De Griekse wiskundige Archimedes gaf ook een klap op de ontwikkeling. En ook Leonardo da Vinci stoeide met het idee, al zette de Italiaanse alleskunner de schroef op iets wat we nu als een helikopter herkennen. De scheepsschroef zelf moest wachten tot de uitvinding van een bruikbare stoommachine. Hoe fijn zou het voor de handel niet zijn, als de onvoorspelbare zeilschepen vervangen zouden kunnen worden door een betrouwbare krachtbron in het ruim?\u003C/p\u003E\r\n\u003Ch3\u003EToekomst zien in de raderboot\u003C/h3\u003E\r\n\u003Cp\u003EDat vooruitzicht zet de technologische pioniers in de maritieme wereld aan het denken. Ze worstelen collectief met twee hoofdproblemen. De eerste is dat er in de scheepsromp een gat moet komen voor de door de stoommachine aangedreven as. Dat probleem blijkt overkomelijk. Het tweede probleem leidt tot een technologische tweestrijd. Aan de ene kant zijn er de uitvinders die brood en toekomst zien in de raderboot. Aan de andere kant zijn er de techneuten die veel meer zien in het vervolmaken van een idee waar al eeuwen mee wordt gespeeld: de schroef.\u003C/p\u003E\r\n\u003Cp\u003EDie nieuwe vinding bestaat uit een naaf met daarop minimaal twee bladen, die symmetrisch onder een hoek zijn geplaatst. Bij het draaien ontstaat er dan een drukverschil tussen de voor- en achterzijde, zoals dat bijvoorbeeld ook gebeurt met de ouderwetse ventilator die ’s zomers thuis verkoeling biedt.\u003C/p\u003E\r\n\u003Ch3\u003EVaders van de scheepsschroef\u003C/h3\u003E\r\n\u003Cp\u003EDe gepatenteerde vaders van die scheepsschroef komen uit Oostenrijk, Engeland en Zweden: Josef Ressel, Francis Petit Smith en John Ericsson. Van dat drietal geldt Josef Ressel, een uit Bohemen afkomstige bosbouwambtenaar met voorliefde voor techniek, als de voorloper. Hij vraagt op 11 februari 1827 een octrooi aan op een aandrijfwiel waarmee schepen zich kunnen voorttrekken.\u003C/p\u003E\r\n\u003Ch3\u003EOorlogsschip USS Princeton\u003C/h3\u003E\r\n\u003Cp\u003EDe Brit Petit Smith doet negen jaar later hetzelfde na uitgebreide testen met een modelboot. Hij bouwt in 1839 met succes het eerste door een schroef aangedreven stoomschip, die niet toevallig de SS Archimedes wordt gedoopt. De via Engeland naar de Verenigde Staten geëmigreerde Zweed John Ericsson bouwt enkele jaren later het oorlogsschip USS Princeton. Dit is het eerste schip met twee tegen elkaar in draaiende schroeven. Geen enkel ander marineschip kan op dat moment tippen aan de snelheid van de USS Princeton.

The ancient Egyptians were already puzzling on a better propulsion. The Greek mathematician Archimedes was pushing for its development. And Leonardo da Vinci also toyed with the idea, although the Italian all-rounder put the screw on something we now recognize as a helicopter. The ship's propeller itself had to wait until the invention of a usable steam engine. Wouldn't it be nice for trade if the unpredictable sailing ships could be replaced by a reliable source of power in the hold? was the general question to be answered.\u003Cbr\u003E\r\n\u003C/p\u003E\r\n\u003Ch4\u003EFuture of the paddle steamer\u003C/h4\u003E\r\n\u003Cp\u003EThe prospect occupies the brains of the technological pioneers in the maritime world. They collectively struggle with two main problems. The first is that there must be a hole in the ship's hull for the shaft driven by the steam engine. That seems feasible. The second problem leads to a technological dilemma. On the one hand, there are the inventors who see the potential and the future in the paddle steamer. On the other hand, there are the technicians who see much more in perfecting an idea that has been toyed with for centuries: the propeller.\u003C/p\u003E\r\n\u003Cp\u003EThis new invention consists of a hub with at least two blades on top, which are symmetrically placed at an angle. When running, there is a pressure difference between the front and rear, as is the case with the old-fashioned fan that provides cooling at home in the summer.\u003C/p\u003E\r\n\u003Ch4\u003EFathers of the ship's propeller\u003C/h4\u003E\r\n\u003Cp\u003EThe patented fathers of the ship's propeller come from Austria, England and Sweden: Josef Ressel, Francis Petit Smith and John Ericsson.

In 1839 he successfully built the first propeller-driven steamship, which was not coincidentally christened the SS Archimedes. A few years later, the Swede John Ericsson, who had emigrated to the United States via England, built the warship USS Princeton. This is the first ship with two propellers rotating against each other. No other naval ship at that time could match the speed of the USS Princeton. Since then, the ship's propeller has been dominant.\u003C/p\u003E\r\n\u003Ch4\u003EExtendable wings\u003C/h4\u003E\r\n\u003Cp\u003EBut with a footnote.
