Abstract: In a fully articulated helicopter rotor head, utilizing an elastomeric bearing (36) to support each rotor blade (2) and react centrifugal flight loads, a blade restraint (52), effective in three axes is provided for use during blade folding for aircraft stowage purposes (Fig. 1). The restraint allows the blade to be folded through a predetermined fold plane, and held there while preventing or minimizing deflection of the elastomeric bearing (36).

Abstract: Radiant energy (7) is used in conjunction with a boron phosphide semiconducting electrode (2) to at least partially power an electrolytic cell (1) in the generation of hydrogen (8), utilizing a bromide, preferably hydrogen bromide, as the essential electrolyte component in the electrolytic cell. This solves overvoltage and corrosion, problems associated with the use of conventional electrolyte (5) results in the broadening of the selection of semiconductor electrodes which can be used in the process and apparatus of the present invention enabling the boron phosphide semiconducting electrode to produce superior anticorrosive and radiant energy gathering results over conventional systems. The boron phosphide semiconductors (2, 3) can be either boron phosphide alone or multilayered structures with other semiconducting material. The hydrogen generated from such systems can be used to power a fuel cell.

Abstract: A wire of a normally nonforgeable composition, having improved resistance to fracture during working, handling and use is comprised of a portion with a rapidly quenched structure as a continuous stratum along its length. A preferred wire useful for fusion welding has a circular cross section with a micro-crystalline surface portion of at least 30 volume percent of the wire. Other preferred wires have elliptical or rectangular cross sections with amorphous strata continuous along their lengths.

Abstract: L'appareil ci-decrit permet l'amortissement effectif de l'energie vibratoire des aubes. Les concepts concernent essentiellement l'amortissement dit aube-aube en comparaison a l'amortissement aube-sol. Les amortisseurs (26) utilises ont une geometrie en coupe en forme de "T" et sont concus pour s'etendre sur la circonference d'un rotor (12) d'un moteur entre les sections de plate-forme (22) de chaque paire d'aubes (14) du rotor. Les amortisseurs (26) sont extremement legers de telle sorte que les forces de charge de glissement requises pour generer un contact de glissement entre l'amortisseur (26) et les plate-formes (22) des aubes sont faibles.

Abstract: Coated article and method for producing the coated article. The article (1) is coated with a system which provides protection against oxidation and corrosion and which significantly reduces the substrate temperature. An MCrAlY layer (2) is applied to the article (1) to be protected and a columnar grain ceramic (4) is applied by vapor deposition to the MCrAlY coated article. An alumina layer (3) which exists between the MCrAlY layer (2) and the columnar ceramic layer (4) provides for the adherence of the columnar layer to the MCrAlY layer.

Abstract: A helicopter having an automatic flight control system including an inner, stability loop is rendered less sensitive to short-term, inadvertent pilot inputs by applying a washed-out derivative (36) of a stick position signal (32) to the inner stability loop in a sense to countermand the pilot action. Using a washed-out signal countermands only short term rapid stick motions, which may be induced by the pilot actively, but inadvertently, or inactively due to coupling between the pilot or the stick and motion of the fuselage, while permitting purposeful longterm stick positions to have the full, intended effect.

Abstract: An alloy composition casting scheme and specific heat treatment process are described for the production of directionally solidified single crystal articles which have exceptional properties. The alloy is based on the Ni-Al-Mo system, preferably with additions of Ta. The process for producing the article includes directional solidification at a high rate to produce a fine dendritic microstructure. A combined homogenizing and solution treatment is performed to provide a unique chemically homogeneous single phase microstructure. This homogeneous article is rapidly quenched and then aged at an intermediate temperature to develop a controlled uniform distribution of fine gamma prime phase particles.

Abstract: Coated article and method for producing the coated article. The article (1) is coated with a system which provides protection against oxidation and corrosion and which significantly reduces the substrate temperature. An MCrAlY layer (2) is applied to the article to be protected and a columnar grain ceramic (5) is applied by vapor deposition to the MCrAlY coated article. An alumina layer (4) which exists between the MCrAlY layer (2) and the columnar ceramic layer (5) provides for the adherence of the columnar layer to the MCrAlY layer. An important feature of the invention is that the interface (3) between the MCrAlY layer and the alumina layer has a low surface roughness and this greatly improves the columnar ceramic layer adherence.
