The swinging bucket rotor allows the tube to change angle during the run. The buckets are vertical when stopped and horizontal when running. The parallel geometry of the swinging buckets allow the ...

The Kaman K-MAX has intermeshing rotors eliminating the need for a tail rotor. These opposite-spinning rotors lend the K-MAX a natural tendency to hover, making it more stable. The K-MAX is ideal ...

Before the digital age, when transistors were expensive, unreliable, and/or nonexistent, engineers had to use other tricks to do things that we take for granted nowadays. Motor positioning, for ...

The control complexity is due to the mechanical complexity of the swashplate, which translates control inputs into both collective and cyclical changes in the angle of attack of the rotor blades.

During standing tests, rotor assistance enabled the robot to resist external disturbances effectively, maintaining posture with minimal pitch angle shifts (3°) and quickly stabilizing its center ...
