	Rotary wing device (US4243190)
		A rotary wing device has a circular stabilizer disc and, secured normally thereto, a bilaterally symmetrical wing member having a first symmetry axis intersecting the center of the stabilizer disc.
		The ends of the wing member at the first symmetry axis are connected through pin connections to a string harness whereby the device functions as a kite when the wing member rotates about the first symmetry axis.
		at least one guy wire connecting the frame of the said stabilizer disc to the frame of the said wing member in each quadrant of the device, each said guy wire functioning to transfer stresses from the frame of the said stabilizer disc to the frame of the said flat wing member.

	Database Introduction
		The load distribution on a fixed wing configuration is considerably different from that on a rotary wing configuration due to the incoming velocity variation.
		Rotary wing flowfields, especially in hover, are highly susceptible to facility recirculation effects and ensuing aperiodicity(Shinoda and Johnson, Piziali and Felker).
		The tip-vortices trailed from a rotary wing, however, stay in the vicinity of the rotor blades for a few revolutions of the vortex, significantly affecting the bound circulation distribution on the rotor blade.

	Flex-Wing Rotary Cutters
		Wings also fold up to 90 degrees for transport and storage.
		The wings operate simultaneously on the HX and independently on the CX for quick transition to and from transport mode.
		HX and CX flex-wing rotary cutters feature heavy-duty construction and are designed to last for years under the toughest cutting conditions.

	Technology: The Pivoting Wing Paradigm
		Substitute "jet" for "rotary wing" as a means of generating and vectoring thrust in combination with a fixed wing fuselage, and you are still inside the Paradigm.
		Imagine a different kind of airplane: in pitch the wing is free with regard to the fuselage, and the fuselage is free with regard to the wing, and together they are free with regard to gusts of wind.
		Instead of forcing the wing to a certain angle of attack, the wing is allowed to adjust itself.

	Technology: Tilt-Body
		Tilt-rotors of necessity have transmissions crisscrossing the wing: having the engine in the fuselage obviously means transmissions to the tip rotor assemblies; and separate engines in each tip rotor need to be interlocked so that one engine can power both rotors in the event of engine failure.
		The lower weight of the pivoting wing tilt-body compared to a tilt-rotor means less fuel for a given mission, and weight reduction on both those counts mean that a smaller engine can be chosen for a given design, which in turn means even lower fuel consumption.
		More standard fixed wing vehicles can be made more modular, but the "single pin release" that comes naturally to the pivoting wing would come only at a cost and weight penalty to standard fixed wings.

	Back Pain in the Naval Rotary Wing Community
		The USMC alone has around 3,000 rotary wing aviators and if 80 percent of them suffer with back pain the annual cost is $3.6 million for Marine assets alone.
		Though back pain in rotary wing aviators is a well-known problem, not enough has been done to alleviate it.
		There is no quick and easy way to eliminate a problem that has plagued rotary wing aviators for many years, but with careful attention, sustained focus, and further research, much progress can still be made.

	Georgia Institute of Technology :: News Room :: Tech Successfully Flies Smarter Rotary Wing UAV
		GT Max, the first rotary wing UAV, is able to learn as it flies, maneuver aggressively and automatically plan a route through obstacles thanks to its Open Control Platform system.
		Researchers from several partner institutions and organizations have helped to successfully build, test and fly the first rotary wing UAV, a helicopter called GTMax, with capabilities of flight control fault identification and reconfiguration, adaptive control and agile maneuvering — all operating on a single vehicle and under a single software architecture.
		Advances in rotary wing UAVs are particularly important because of their requirement to take off and land in difficult terrain and restricted-size areas, such as ship decks, and their ability to hover while they identify and inspect specific locations.

	Introduction to Helicopter Flight
		With early fixed-wing aircraft, the propulsion system (the engine and propeller) and the lift device (the wing) were relatively simple and the challenge was developing control systems to keep the aircraft in level flight and to change direction.
		But with a helicopter, more powerful, and lighter engines were needed and it was many years before relatively lightweight, powerful enough engines were developed that could turn a rotor fast enough to life an aircraft off the ground.
		Their Fa 61 aircraft used a conventional biplane fuselage, but instead of wings it had two large rotors mounted on outriggers on either side of the aircraft.
