Principle drawing of a cyclogyro.

The cyclogyro, or cyclocopter, is an aircraft configuration that uses a horizontal-axis cyclorotor as a rotor wing to provide take and most incessantly also propulsion and delight in an eye on. In conception, the cyclogyro is able to vertical seize off and landing and hovering performance like a helicopter, while doubtlessly making the most of just a few of some high-quality benefits of a fixed-wing aircraft.

The cyclogyro is determined from the Flettner airplane which uses a cylindrical wing rotor to harness the Magnus enact.

Principles of operation[edit]

The cyclogyro wing resembles a scuttle wheel, with airfoil blades changing the paddles. Like a helicopter, The blade pitch (angle of assault) may per chance per chance well moreover moreover be adjusted both collectively all collectively or cyclically as they transfer across the rotor’s axis. In fashioned forward flight the blades are given a puny obvious pitch on the upper and forward portions of their arc producing take and, if powered, also forward thrust. They are given flat or detrimental pitch on the bottom, and are “flat” during the remainder of the circle to invent tiny or no absorb various directions. Blade pitch may per chance per chance well moreover moreover be adjusted to alternate the thrust profile, allowing the cyclogyro to commute in any course with out the necessity for separate delight in an eye on surfaces.[1] Differential thrust between the two wings (one on both aspect of the fuselage) may per chance per chance well moreover moreover be used to flip the aircraft spherical its vertical axis, though ancient tail surfaces may per chance per chance well moreover be used to boot.[2]

History[edit]

Jonathan Edward Caldwell took out a patent on the cyclogyro which used to be granted in 1927, nevertheless he by no scheme adopted it up.[3]

The Schroeder S1 of 1930 used to be a plump-dimension prototype which used the cyclogyro for forward thrust top most likely.[quotation wanted] Adolf Rohrbach of Germany designed a plump VTOL model in 1933, which used to be later developed in the US and featured an unlimited streamlined fuselage to retain the wings a ways from the bottom.[4][5] One other example used to be built by Rahn Aircraft in 1935, which used two gargantuan-chord rotary wings as a substitute of a multi-blade wheel pushed by a 240 hp supercharged Wright Whirlwind[6]

The cyclogyro has been revisited in the twenty-first century, as a that it is most likely you’ll per chance per chance perchance moreover factor in configuration for unmanned aerial autos.[7][8][9]
