    Notes: Monolithiated 1,7-dicarba-closo-dodecaborane(12) reacts with O-isopropylidene derivatives of D-erythrono-1,4-lactone (1), L-mannono-1,4-lactone (3) and with tetra-O-trimethylsilylated D-glucono-1,5-lactone (2) and D-gulono-1,4-lactone (4) to give the title compounds after deprotection. An X-ray structure analysis of the protected L-mannofuranose carborane derivative 9 reveals that the more stable anomer has the β-L configuration.

    Aerodynamic characteristics of a propeller powered high lift semispan wing (1992)

    Description: An experimental investigation was conducted on the engine/airframe integration aerodynamics for potential high-lift aircraft configurations. The model consisted of a semispan wing with a double-isolated flap system and a Krueger leading edge device. The advanced propeller and the powered nacelle were tested and aerodynamic characteristics of the combined system are presented. It was found that the lift coefficient of the powered wing could be increased by the propeller slipstream when the rotational speed was increased and high-lift devices were deployed. Moving the nacelle/propeller closer to the wing in the vertical direction indicated higher lift augmentation than a shift in the longitudinal direction. A pitch-down nacelle inclination enhanced the lift performance of the system much better than vertical and horizontal variation of the nacelle locations and showed that the powered wing can sustain higher angles of attack near maximum lift performance.
