Commentators at the time raised eyebrows at the creation of such a highly geared buyout structure for a group with heavy capital spending commitments - some £9.5bn is earmarked for BAA's three London airports in the next decade.
Composite materials exhibit complex failure behavior under impact loading especially such as that for composite landing gear structure.
Finally, the proposed methods were utilized to predict the response of a landing gear structure fabricated using braided composites under bending.
By optimising the geometric parameters of the gearbox, such as the module, number of teeth, axial clearance, and backlash, it is possible to obtain a gear structure with high bending and contact strength and to minimise the torsional vibration, transmission error and gear-rattling noise.
This paper proposes a combination of slidable flat washer and four-jaw auto-centering chuck to meet the clamping requirement and provide millimeter-grade carrier locating precision; realization of auto offset correction by use of the clamping jaws of a quasi-planetary gear structure is a guarantee of hoisting work on the carrier in the condition of gripper swinging.
An interlocking gear structure synchronizes the movement of the insect's hind legs during a jump and prevents it from spinning out of control like a plane that has lost control of its yaw.
Without the gear structure, such synchronized movement would be difficult, as the spike in neural activity that generates this movement lasts much longer, about 1 millisecond, the group reports online today in Science.
But Sallie Mae doesn't plan to change its business practices, he said, as the company has long been "geared and structured to full compliance".
Ultra-high strength steels employed in safety-critical applications, such as AerMet®100 used in aircraft landing gear structures, are managed on very conservative rejection criteria for small defects and repair options are limited.
The two types of typical coupler and draft gear structures are shown in Fig. 1a, b.
