This three-engined helicopter has a single large main rotor and smaller tail rotor. On a helicopter, the main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic ...
When a helicopter is being maneuvered, its disk loading changes. The higher the loading, the more power needed to maintain rotor speed. [3] A low disk loading is a direct indicator of high lift thrust efficiency. [4] Increasing the weight of a helicopter increases disk loading. For a given weight, a helicopter with shorter rotors will have ...
The Hillberg EH1-01 RotorMouse is an American helicopter that was designed by Donald Gene Hillberg and produced by Hillberg Helicopters of Fountain Valley, California, first flying in 1993. Now out of production, when it was available the aircraft was supplied as a kit for amateur construction .
Coning is a phenomenon which affects helicopter rotor discs. The tips of the helicopter rotor blades move faster through the air than the parts of the blades near the hub, so they generate more lift, which pushes the tips of the blades upwards, resulting in a slight cone shape to the rotor disc. This is balanced by centrifugal force.
The aircraft can also be built new from a complete kit. In either case the resulting MH-1 complies with the US experimental - amateur-built rules. [1] [2] [3] The MH-1 features a single main rotor with a two-bladed tail rotor, a single-seat enclosed cockpit with a windshield and skid-type landing gear. Its 19 ft (5.8 m) diameter two-bladed ...
Tilts main rotor disk left and right through the swashplate: Induces roll in direction moved To create movement to sides To move sideways Collective Collective angle of attack for the rotor main blades via the swashplate: Increase/decrease pitch angle of all main rotor blades equally, causing the aircraft to ascend/descend Increase/decrease torque.
In aeronautics, a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades. Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot's commands from the non-rotating fuselage to the rotating rotor hub and mainblades.
Flapback [1]: 3:28 or blowback [2]: 2–14, 2–20, 2–21 [3] is the tilting of a helicopter rotor disc, usually aft (backwards), which occurs in several circumstances. In normal operating circumstances, forward flight results in flapback caused by dissymmetry of lift and the transverse flow effect .
