    Topics: Chemistry and Pharmacology
    Description / Table of Contents: Summary For the isolation of the intermetallic compounds Al2Cu, Al12Mg17, Al3Fe, Al9Co2 and Al3Ni in their binary alloys a new method is proposed: Sample alloy particles are placed in a flask with a methanolic solution of benzoic acid (20% wt.), oxine (5% wt.), chloroform (20% vol.) and sodium hydroxide (0.02% wt.). After sufficient time of agitation, the intermetallic compounds remain quantitatively in the solution.
    Notes: Zusammenfassung Zur Isolierung der intermetallischen Verbindungen aus den entsprechenden binären Legierungen wird die Probe mehrere Stunden bis Tage unter Rühren mit einer methanolischen Lösung von Benzoesäure (20%), Oxin (5%), Chloroform (20%) und Natriumhydroxid (0,02%) behandelt. Hierbei wird die Matrix aufgelöst und die intermetallischen Verbindungen bleiben zurück.

    Description: A fluidic emergency roll control system for aircraft stabilization in the event of primary flight control failure was evaluated. The fluidic roll control units were designed to provide roll torque proportional to an electrical command as operated by two diametrically opposed thrust nozzles located in the wing tips. The control package consists of a solid propellant gas generator, two diametrically opposed vortex valve modulated thrust nozzles, and an electromagnetic torque motor. The procedures for the design, development, and performance testing of the system are described.

    Description: The design, development, fabrication and test evaluation of two prototype fluidic emergency thrusters (FET) for aircraft stabilization are discussed. The fluidic control units were designed to provide, between two diametrically opposed nozzles, a thrust differential proportional to an input voltage signal. The emergency roll control requirements of the X-14 VTOL research aircraft were defined as typical design goals. Two control units, one on each wing tip, are intended to provide a maximum thrust of 224 pounds per unit. The units are designed to operate with 2500 psig, 2000 F gas from a solid propellant gas generator. The emergency system including the gas generator was designed to add less than 11 pounds per wing tip. The operating time under emergency conditions was specified as five seconds. The fluidic emergency thruster is similar in concept to a JATO system but has the added feature of controllable thrust.
