Lenses axial space ray tracing measurement
Optics Express, 2010 In order to achieve the precise measurement of the lenses axial space, a new lenses axial space ray tracing measurement (ASRTM) is proposed based on the geometrical theory of optical image. For an assembled lenses with the given radius of curvature r(n) and refractive index nn of every lens, ASRTM uses the annular laser differential confocal ...

Axial Spacing Effects on Rotor-Rotor Interaction Noise and Vibration in a Contra-Rotating Fan
International Journal of Aerospace Engineering, 2019 Because of the potential technical advantages, the contra-rotation technology has become a renewed interest in aviation and other applications. Contra-rotation increases efficiency in comparison with the single-rotor design, but this advantage is not ...

Axial and radial forces of cross-bridges depend on lattice spacing. [PDF]
PLoS Computational Biology, 2010 Nearly all mechanochemical models of the cross-bridge treat myosin as a simple linear spring arranged parallel to the contractile filaments. These single-spring models cannot account for the radial force that muscle generates (orthogonal to the long axis

Design and Experimental Validation of a Ducted Counter-rotating Axial-flow Fans System [PDF]
, 2012 An experimental study on the design of counter-rotating axial-flow fans was carried out. The fans were designed using an inverse method. In particular, the system is designed to have a pure axial discharge flow.

Influence of Aerodynamic Interaction on Performance of Contrarotating Propeller/Wing System
Aerospace, 2022 This paper gives a quantitative account of the influence of slipstream on the aerodynamic performance of a contrarotating propeller (CRP)/wing system, and compares it with the CRP and clean wing. To accurately evaluate the complex aerodynamic interaction,
