72 PROPELLER ARRANGEMENT US13027653 2011-02-15 US20110223020A1 2011-09-15 Alexander V. LAVRENKO
A propeller arrangement has a first propeller assembly providing a row of first propellers, and a second propeller assembly, rearward of the first propeller assembly, providing a row of second propellers. The first and second propellers are radially extendable and retractable. The propeller arrangement further has a control system for controlling the extension and retraction of the first and second propellers. The control system is arranged such that when the propellers of one of the first and second propeller assemblies extend, the propellers of the other of the first and second assemblies retract.

74 Methods and apparatus for adjustable surfaces US11670736 2007-02-02 US07777165B2 2010-08-17 Terry M. Sanderson; Jamie W. Clark
Methods and apparatus for systems having deployable elements according to various aspects of the present invention comprise a system including a deployable surface and an adaptive actuator including a polymer foam. In one embodiment, the system comprises a vehicle including a deployable wing comprising an exterior surface. The exterior surface may be adjusted by adjusting the shape, size, position, and/or orientation of the adaptive actuator.
75 Propeller with Flexible Variable Blades US12115457 2008-05-05 US20090274557A1 2009-11-05 Khymych Vasyl
The proposed propeller consists of the rotor disc assembly 1, two or more flexible variable-length blades 2, a precise number of which depends on the desired lifting force; carrying capacity and the airflow involved in the process of the aircraft take off and retention in the air, device or devices, which control retraction of blades, and devices which controls blade pitches 3. The blade represents a flexible strip made of steel composite or any other suitable material. The flexible nature of the strip and the fixture of the inner end of each blade on the barrel 4 located within the rotor disc assembly on which blades are reeled when retracted; provides for the blades pulling out automatically with minimal effort and no additional effort or engine force. This effect is reached through the blades being dragged out by the centrifugal force created by the rotation of the rotor and amplified by the load attached to the outer end of each blade. Centrifugal force when reaches appropriate level, keeps the blades in straighten and stiffen state, which allows for the operation of the aircraft similar to any propeller with fixed-length blades.

78 Rotor system having alternating length rotor blades and positioning means therefor for reducing blade-vortex interaction (BVI) noise US569390 1995-12-11 US5735670A 1998-04-07 Robert C. Moffitt; David G. Matuska; Evan A. Fradenburgh
A Variable Diameter Rotor (VDR) system (4) having telescoping odd and even blade assemblies (O.sub.b, E.sub.b) wherein the odd blade assemblies define a radial length R.sub.O and the even blade assemblies define a radial length R.sub.E. Each blade assembly (O.sub.b, E.sub.b) defines an internal chamber (64) for accepting a positioning means (70) operative to effect telescopic translation of the blade assemblies (O.sub.b, E.sub.b) such that the radial length R.sub.E of the even blade assemblies (E.sub.b) is equal to the radial length R.sub.O of the odd blade assemblies (O.sub.b) in a first operating mode, and such that the radial length R.sub.E is between about 70% to about 95% of the length R.sub.O in a second operating mode. The positioning means (70) includes a centrifugal restraint assembly (80) disposed within each internal chamber (64) of the rotor blade assemblies (O.sub.b, E.sub.b), a stop surface (64s) formed internally of each internal chamber (64), and an actuation means (90) operative for transpositioning the centrifugal restraint assemblies (80) within the internal chambers (64) such that, in one operating mode, the centrifugal restraint assemblies (80) are disposed in abutting engagement with the stop surfaces (64s) and, in another operating mode, the actuation means (90) is disposed in abutting engagement with the centrifugal restraint assemblies (80) of at least one of the blade assemblies (O.sub.b, E.sub.b).
