VectoRotor | |||
VectoRotor combines buoyant lift with dynamic lift in a
revolutionary hybrid, rotary-wing aircraft. The VectoRotor’s
unique joined-rotor design (U.S. Patent No. 5,931,411) distinguishes it
from other hybrid, rotary-wing designs. The joined-rotor concept
consists of two rotors – an upper rotor with drooped blades and
a lower rotor with blades that are coned upward. The resulting rotor
configuration provides vertical thrust and direct lateral force control
for precision hovering in a structurally efficient design. While
the joined-rotor concept may also have future applications as a non-hybrid
VTOL aircraft, its most promising initial application is in the vertical,
heavy-lift VectoRotor. When compared to conventional helicopters
in civil vertical, heavy-lift applications, the VectoRotor offers dramatic
improvements. These improvements would include:
The center-body, a large helium-filled cell, floats the unladen aircraft, thus conserving fuel for lifting cargo at lower cost. The control cabin below will have a cargo hoist. VectoRotor will fly at least up to 50 mph. Payloads of six and twelve tons are planned, matching current helicopter logging capability. |
