THE NEXT GENERATION MAGNUS STABILIZERS
Around 1970 – nearly 50 years ago- Theo Koop invented the Magnus Effect stabilizer. At that time he built various prototypes of these stabilizers, but due to technical limitations production was discontinued.
However, about 10 years ago, Koop collaborated with Quantum Controls Engineering to redesign his former Magnus Effect stabilizer concepts. This joint effort proved to be fruitful and paved the way for the development of the AtZeroSpeed, AtCruiseSpeed and AtFullSPeed techniques. Each one of these remarkable concepts have now been fully integrated in what we call The Next Generation Magnus Stabilizer. Resulting in a highly versatile and retractable stabilizer system.
Back in 2011 a company called RotorSwing Marine was put in place, which at the time aimed mainly at the typical Dutch displacement vessels. The Magnus effect proved to be beneficial for low speed applications and soon became a great success which was copied by others.
The RotorSwing stabilizer and its concept copys were highly effective but had one short coming. The perpendicular to the hull protruding rotors caused drag at higher speeds. Cruising speeds around 10 knots could easily result in a drop of velocity around 0.6 to 0.8 knots. Koop found a solution to this drag issue by adaptively and proportionally folding the rotors backwards, just like the wings from fighter airplanes. He called his invention RAKE. (Revolutionary Adaptation of Kinematic Energy)
The Rake function in its current form is capable of stabilizing up to 25 knots. This has opened up another large market for faster cruising vessels. Koop patented these original ideas to prevent further copying of his inventions.
Recently RotorSwing Marine invented another function for the RotorSwing, which only has become feasible due to technological advancements, a combination of RAKE and ZeroSpeed. While at anchor or adrift, the rotors swing back and forth to mimic the flow of water over the rotors through which large lift forces are being generated.
A summary of the NEXT Generation RotorSwing 140 stabilizer system is as follows:
· ATZero- ATCruise- and ATFullSpeed in a single combined system.
· Retractable against the hull
· Fully electric with advanced touchscreen control panel
· No forward or backward motion induced by ZeroSpeed function
· Ideal for refit due to small size of internal components
· Flexible installation locations
Special feature for sportfishing yachts
· The RotorSwing roll damping system can be engaged while slowly going astern This is ideal for sport fishers while hauling in their catch.
Innovation has always been top priority for RotorSwing Marine. Many improvements and additions have been implemented after the invention and first commercialization phase. The company is excited that it has now surpassed the phase that the Magnus RotorSwing system can only be installed on displacement vessels. RAKE is the answer to provide an extremely efficient multifunctional roll damping system to vessels up to 35 meters.
