Abstract: Methods and apparatus for mechanically driving components in a desired direction, such as in a moving craft. In one embodiment, the craft comprises a vertical or short takeoff and landing (VSTOL) aircraft comprising one or more rotating rings having airfoils disposed around a periphery thereof. In one variant, the one or more rings are driven by a multi-level drive apparatus having a plurality of angularly offset roller-based drive levels and a plurality of corresponding angularly offset driven members (e.g., rings), the plurality of driven members coupled to e.g., the at least one rotating ring. Advantageously, use of this arrangement provides enhanced reliability as well as opportunities for selective load balancing, and obviates comparatively heavy lubrication components such as seals and liquid lubricants, thereby also saving weight when applied to the host craft.

Abstract: Apparatus for vertical or short takeoff and landing, and operational control during flight. In one embodiment, the apparatus includes a main body assembly, the main body assembly including: a fuselage, the fuselage includes one or more power motor assemblies and one or more actuator motor assemblies; a plurality of power mounting bodies and a plurality of power/articulation mounting bodies; a static rail that is operatively coupled with the plurality of power mounting bodies; a transient rail that is operatively coupled with the plurality of power/articulation bodies; and a plurality of airfoils, each of the plurality of airfoils being coupled to a respective power/articulation mounting body. Various sub-systems of the apparatus and methods of manufacture and use are also disclosed.

Abstract: Methods and apparatus for vertical or short takeoff and landing, and operational control during flight. In one embodiment, the apparatus comprises two or more counter driven rings with one or more airfoils attached. In one variant, there is an upper ring and a lower ring, each with multiple airfoils attached. In one variant, lift is generated largely via ambient air currents, allowing for long term on-station operation of the device. In another variant, a fuselage (or parts thereof) of the apparatus can be independently controlled, including for example as to attitude relative to other components of the craft.

Abstract: A silicone film is attached to a surface by chemical bonding. The silicone film consists of chains of siloxane groups, each chain terminating in an end molecule which is either an ester, an ether, or a halogen. The end molecule is allowed to react with water to produce an OH group. The surface is then contacted with a capping agent which reacts with the OH group to produce a new end group which improves the properties of the film. A premix including a tertiary amine can be initially applied to the surface to react with any acidic molecules generated during the process, in order to form non-reactive and water-soluble amino salts.
