The Syncrolift shiplift is a piece of equipment for lifting boats, ships and vessels onto land and back at sea for maintenance work or repair. The vessel is maneuvered over a submerged cradle, which is then lifted by a set of synchronized hoists or winches. The vessel can be worked upon in place, or it can be moved inland.
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England , rotational, like the Falkirk Wheel in Scotland , or operate on an inclined plane , like the Ronquières inclined plane ...
Rotor ship E-Ship 1. A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion. "The idea worked, but the ...

The rotor head, pre-rotator shaft, and Subaru engine configuration on a VPM M-16 autogyro. An autogyro is characterized by a free-spinning rotor that turns because of the passage of air through the rotor from below. [6] [7] The downward component of the total aerodynamic reaction of the rotor gives lift to the vehicle, sustaining it in the air ...

It had a single three-blade rotor originally powered by a 75 horsepower (56 kW) engine. The first "free" flight of the VS-300 was on 13 May 1940. [2] The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque.
