A rotary-wing aircraft, rotorwing aircraft or rotorcraft is a heavier-than-air aircraft with rotary wings that spin around a vertical mast to generate lift. The assembly of several rotor blades mounted on a single mast is referred to as a rotor .
A rotor wing is a lifting rotor or wing which spins to provide aerodynamic lift. ... Conventional rotary wings as used by modern rotorcraft. Spanwise horizontal-axis.
This is a list of large aircraft, including three types: fixed wing, rotary wing, and airships.. The US Federal Aviation Administration defines a large aircraft as any aircraft with a certificated maximum takeoff weight (MTOW) of more than 12,500 lb (5,700 kg) [1]
Rotary wing squadrons use "H." Marine squadrons are always noted by the second letter "M." Squadron numbering is not linear as some were numbered in ascending order and others took numbers from the wing or the ship to which they were assigned. From 1920 to 1941, Marine flying squadrons were identified by one digit numbers.
Conventional rotary-wing aircraft use a set of complex mechanical gearboxes to convert the high rotation speed of gas turbines into the low speed required to drive main and tail rotors. Unlike powerplants, mechanical gearboxes cannot be duplicated (for redundancy) and have always been a major weak point in helicopter reliability.
The U.S. Navy first used the term "wing" to describe the level of command above its aircraft squadrons when it established five Patrol Wings in 1937. In 1938 it organized the squadrons flying from the five aircraft carriers in commission at the time into Carrier Air Groups. Those Carrier Air Groups are the forerunners of today's Carrier Air Wings.
In April 2018 a new squadron type designation was created apart from the existing "V" for fixed wing squadron and "H" for rotary wing squadron when Air Test and Evaluation Squadron Twenty Four (UX-24) was programmed for establishment to develop unmanned aerial systems (UAS) for the U.S. Navy and Marine Corps.
Sikorsky S-72 modified as the X-Wing testbed, with experimental 4-blade main rotor. With a single main rotor helicopter, the creation of torque as the engine turns the rotor creates a torque effect that causes the body of the helicopter to turn in the opposite direction of the rotor. To eliminate this effect, some sort of antitorque control ...
