In 1974, the company eliminated the 2-cycle engine and, unable to find a manufacturer to make their 4-cycle engine suitable for the helicopter, began production of their own engine. This engine, called the RotorWay RW133 , was a 4-cycle engine that was able to provide a cruise speed of 80 mph (130 km/h) with a range of 120 miles (193 km) and a ...
It had a single three-blade rotor originally powered by a 75 horsepower (56 kW) engine. The first "free" flight of the VS-300 was on 13 May 1940. [ 2 ] The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque .
Compound rotorcraft augment the rotor with additional thrust engines, propellers, or static lifting surfaces. Some types, such as helicopters, are capable of vertical takeoff and landing. An aircraft which uses rotor lift for vertical flight but changes to solely fixed-wing lift in horizontal flight is not a rotorcraft but a convertiplane.
The powered rotors of a tiltrotor (sometimes called proprotor) are mounted on rotating shafts or nacelles at the end of a fixed wing, and used for both lift and propulsion. For vertical flight, the rotors are angled to provide thrust upwards, lifting the way a helicopter rotor does.
The various types of such rotor wings may be classified according to the axis of the rotor. Types include: [1] [2] Vertical-axis. Conventional rotary wings as used by modern rotorcraft. Spanwise horizontal-axis. Wing rotor: an airfoil-section horizontal-axis rotor which creates the primary lift. Magnus rotor: a rotor which creates lift via the ...
One month into his stay at the NICU at M Health Fairview Masonic Children's Hospital, Cooper got a neighbor, Raghu, who weighed even less than him. The parents quickly connected.
The cyclogyro, or cyclocopter, is an aircraft configuration that uses a horizontal-axis cyclorotor as a rotor wing to provide lift and, sometimes, also propulsion and control. In principle, the cyclogyro is capable of vertical take off and landing and hovering performance, like a helicopter , while potentially benefiting from some of the ...
