The Helicron is an open-wheel car that used a propeller as its drive. The Helicron was abandoned in the late 1930s, but was restored after its barn find in 2000. [1] In the same year, the car was permitted by the French government to drive on the French roads. [2] The car currently resides in the Lane Motor Museum and is on display, as a ...
Among the designs he tried was the Oehmichen No. 2, which employed four two-blade rotors and eight propellers, all driven by a single engine. The angle of the rotor blades could be varied by warping. Five of the propellers, spinning in the horizontal plane, stabilized the machine laterally. Another propeller was mounted at the nose for steering.
Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
The hybrid design is simpler than a pure gasoline drivetrain by eliminating the gearboxes and rotor linkages of a traditional helicopter, while security is higher through two redundant motors. Each propeller blade is driven directly by an independent electric motor and flight control is achieved by varying the RPM of each blade to achieve ...

Compound rotorcraft augment the rotor with additional thrust engines, propellers, or static lifting surfaces. Some types, such as helicopters, are capable of vertical takeoff and landing . An aircraft which uses rotor lift for vertical flight but changes to solely fixed-wing lift in horizontal flight is not a rotorcraft but a convertiplane .
A Mark 46 Mod 5A torpedo is inspected aboard a destroyer in April 2005. Contra-rotating propellers have benefits when providing thrust for boats for the same reasons. ABB provided an azimuth thruster for ShinNihonkai Ferries in form of the CRP Azipod, [1] claiming efficiency gains from the propeller (about 10% increase [2]) and a simpler hull design.
Other terms include ducted propeller or shrouded propeller. [1] When used in vertical takeoff and landing applications it is also known as a shrouded rotor. [2] Ducted fans are used for propulsion or direct lift in many types of vehicle including airplanes, airships, hovercraft, and powered lift VTOL aircraft. The high-bypass turbofan engines ...
