Description: The Tower of Gedser Wind Turbine 1957 Quote from Johannes Juul's speech at the UN conference in Rome, 1961: "The "Gedser Mill" is the most recently built and largest Danish experimental wind power plant and is to a material extent designed on the basis of experience gained from the aforesaid pilot plants. The "Gedser Mill" has a 25 m high tower made of prestressed concrete. On top of the tower is mounted a measuring cylinder carrying the machinery." Source: 1961 - Juul's speech at the UN Conference, Rome "Design of Wind Power Plants in Denmark" 
Fitted with a newer Wincon nacelle from 1993 to November 2019 - the tower is updated for renewed operation. This time for a planned Johannes Juul Prototype, similar in design to the original, however constructed in newer sustainable materials. Quote from Juul's speech in Rome, 1961: "When the blades were designed, it should be remebered that the possiblities of production were restricted, as they could only be made by manual power craftsmanship. In a possible future industrial production in series, these blades can undoubtedly be more cheaply made of pressed steel sheets welded into hollow shell-like constructions to be bolted to the hub by flanges. It is possible as well to make the blades of other material than steel, e.g. plastic reinforced with glass fibre, if this proves economically advantageous." Although the design must be similar to the original, it is important to adapt the operation to the extreme weather conditions of our time. Furthermore, Juul's prototype will be subject to applicable safety requirements. The Energy Museum maintains the display of Juul's rotor as a popular attraction and for teaching students on the subject "green technologies". The Energy Museum is part of the project: Operation of the Gedser Wind Turbine. This item is provided and maintained by Juul's Museum - managed by the Association: Operation of Gedser Wind Turbine.

Quote from Johannes Juul's speech "Design of Wind Power Plants in Denmark" at the UN Conference, Rome, 1961: "The brake flaps (1) make up 12 percent of the surface of the rotor blades and are an integral part of the rotor blades under normal operating conditions of the system. Each flap is fixed to a tubular carrying rod (2) which will, when actuated by the automatics of the mill, travel about 300 mm along the longitudinal axis of the blade and move in a link-motion (3) in the fixed part of the blade. By this movement, the brake flap is twisted about 60° out of the plane of the blade, thus counteractring the remaing part of the blade and bringing the mill to a dead stop. The brake flaps are operated by a hydraulic servo motor (5) in connection of automatics. When the mill starts, the servo-motor will pull the brake flaps into working position. When it stops, the centrifugal power will force the flaps out into braking position. The rotor blade beam (4) is square and consists of 16 mm and 10 mm welded steel plates." |
