Fantastic video I found here of a guy called Clark Cogan performing a vertical take off in his gyrocopter using hydrogen peroxide rockets at the tips of the rotor blades.I was surprised to see find that this was not a new idea and was famously tested on the Fairey Rotodyne (a 50-passenger carrying gyro) in 1957. It is calibrated in degrees, usually with every 30 degrees labeled.
Similar to tiltrotor concept, but with ducted fans. The entire mechanism with adjustable pitch is covered with a large diameter spinner. TOPICS: Electric Pre-Rotator gyrocopter design Pre-Rotator Rotor spin up Short field take offs Vertical take offs Posted By: admin@bag June 11, 2017 Building an electric pre-rotator for your whirlybird is a very simple process – once you know what to watch out for.
Rotors having articulated joints with flapping or universal joint, common to the bladesRotors having articulated joints with flapping or universal joint, common to the blades see-saw type, i.e. A disadvantageous feature of this construction is the fact that the rocking joint has side planes that are milled off at an angle 2-3 degrees to the flat surface, with the result that the fiberglass torsion fixed on the rocking joint has an angle of 4-6 degrees. This classification can include a variety of types of aircraft including fixed-wing aircraft as well as helicopters and other aircraft with powered rotors, such as cyclogyros/cyclocopters and tiltrotors. In VTOL, the exhaust can be varied between vertical and horizontal thrust.
A gyrodyne has the powered rotor of a helicopter with a separate forward thrust system of an autogyro. This causes a vertical compass card that is geared to the rotor gimbal to move. A cyclogyro or cyclocopter has a rotary wing whose axis and surfaces remain sideways across the airflow, as with a conventional wing.

One used the The idea of using the same engine for vertical and horizontal flight by altering the path of the thrust was conceived by In the 21st century, unmanned drones are becoming increasingly commonplace. a fuselage coupled to a strut frame located above the fuselage, the strut frame having a rotor head mounted on the strut frame through a frame joint and having a forward-offset pitch trunnion;the rotor head further including a torsional hub formed of substantially straight composite plates;a rocking joint above the torsional hub and mounted on a hollow hub-shaft,wherein the rocking joint is oriented at an angle of not more than 40° to a longitudinal axis of the torsional hub;the torsional hub having a plurality of plates with a rotor blade coupled to each plate;an engine within the fuselage having a pusher propeller coupled to the engine, the pusher propeller having an adjustable pitch;at least one vertical tail fin with a rudder, the tail fin mated to the fuselage; andthe rear torsional hub having a plurality of pusher propeller blades attached thereto.wherein to fold the strut frame into a horizontal orientation, the plurality of linkage connections of the rotor head and the flexible Hooke's joint are placed on the axis of rotation of the strut frame.6.
The principle of pitch variation of rotor and pusher screw is in manufacturing of special hollow-centered blades inside which there are long torsional bars. A power unit with adjustable pitch pusher propeller is placed behind the cockpit.
A convertiplane takes off under rotor lift like a helicopter, then transitions to fixed-wing lift in forward flight.
A gyroplane comprises a fuselage 1 with a cockpit, with a folding strut mounted on it, a rotor head 3 , with adjustable torsional hub 16 and pusher propeller 5 with adjustable pitch. This was a gyro that could cruise at 200mph! A tiltrotor or proprotor tilts its propellers or rotors vertically for VTOL and then tilts them forwards for horizontal wing-borne flight, while the main wing remains fixed in place.
