An aircraft that depends principally on the lift generated by one or more rotors for its support in flight. synonym: Rotorcraft
disco lighting effect modelled on a helicopter's rotors. 4 or more pinspot lamp s on the end of a number of arms rotate about the central motor / transformer unit.
A power-driven heavier-than-air aircraft that derives its lift in flight from aerodynamic reactions on one or more power-driven rotors on substantially vertical axes. Fr: hélicoptère
an aircraft without wings that obtains its lift from the rotation of overhead blades
a brick with a rotor, so it doesn't glide well when unpowered
a collection of rotating parts going around and around and reciprocating parts going up and down -- all of them trying to become random in motion
a complex collection of rotating assemblies that allow flight characteristics unavailable to fixed wing aircraft
an aircraft An aircraft is any machine capable of atmospheric flight
an aircraft that can take off and land vertically
an aircraft which is lifted and propelled by one or further large horizontal rotors (propellers)
a type of aircraft that uses spinning blades called rotors to fly
a type of VTOL aircraft, but there are very few VTOL airplanes
A mid-air maneuver in which the skier rotates the body 360 degrees.
Simulation of helicopter flight or battle.
An aircraft that can rise or descend vertically, by means of large overhead power-driven rotor or rotors.
A rotor craft with one or more sets of powered blades.
A term for a device that spins very fast and lifts high into the sky, only to explode or burst into a special aerial effect. These are also called planes, sky flyers or UFOs.
A rotary wing aircraft which depends principally for its support and motion in the air upon the lift generated by one or more power driven rotors, rotating on substantially vertical axes.
A flyer in the horizontal position is tossed, then rotates around a vertical axis (like Helicopter blades) before being caught by the original base.
An overhead lift. The partners skate facing each other, with the lifting partner skating backwards. They clasp hands and the lifted partner is raised over the lifting partner's head as in a forward lasso lift. In the air, the lifted partner maintains a position parallel to the ice with an arched back with the legs extended back and split in a "V" position, as though the arms and legs are the blades of a helicopter as the lift is turned by the lifting partner.
Upright aerial spin of 360 degrees.
A rotorcraft that, for its horizontal motion, depends principally on its engine-driven rotors.
A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors consisting of two or more rotor blades. Helicopters are classified as rotorcraft to distinguish them from fixed-wing aircraft because the helicopter derives its source of lift from the rotor blades rotating around a mast. In fact, the word 'helicopter' originates from the Greek words elikoeioas (helical or spiral) and pteron (wing or feather).
