Together with BHGE's Conde, France factory, the combined teams have also successfully supplied many large size globe valves for oxygen service, and severe service sweep angle
73000 series valves for the highly erosive Blackwater letdown applications that are critical for the performance of this plant technology.
How the parameters such as the sweep angle
([LAMDA]), the dihedral angle, the taper ratio will affect the flight performance, how to set the upper and lower limits of these parameters are determined by using theoretical, numerical and experimental approaches along with the designers' experience.
(i) Compared with the works in [4, 17], we extend the morphing dimension into two degree of freedom: wingspan and sweep angle
. Both detailed modeling process based on the Kane method, and explicit expressions of polynomial parameter-dependent LPV system are given.
NOMENCLATURE AR = aspect ratio S = wing wetted area [C.sub.R] = root chord length b = span length [[lambda].sub.R-B] = inboard taper ratio [[lambda].sub.B-T] = outboard taper ratio [[LAMBDA].sub.R-B] = inboard sweep angle
[[lambda].sub.B-T] = outboard sweep angle
[BP.sub.Inboard] = inboard break point [BP.sub.Outboard] = outboard break point [[GAMMA].sub.R-B] = inboard dihedral angle [[GAMMA].sub.B-T] = outboard dihedral angle [M.sub.[infinity] = free stream Mach number Re = Reynolds number [alpha] = angle of attack [PSI] = yaw angle [C.sub.L] = lift coefficient [C.sub.D] = drag coefficient [C.sub.D0] = drag coefficient at zero lift L/D = lift to drag ratio
Most specifically in the firm's cross-hairs are all the electric motors that drive remotely-controlled devices, such as overhead light gun turrets, missile launchers and autoloaders, the sweep angle
of which need to be accurately monitored.
At low speeds, the wing sweep angle
is relatively low, providing an efficient, low-speed aerodynamic design.
As a result, the animals that contact the ground with a steeper limb angle are more easily able to convert the vertical displacement of the center of mass into horizontal movement with less effort since they move through a smaller sweep angle
. In addition, a stiffer limb is more capable of storing energy thus it maybe hypothesized that these animals are able to conserve energy during landing than the animals with less stiff limbs.
The connecting tubes between the inlet and outlets are made from seamless tubes and the indexing tube has a gentle sweep angle
which creates a direction changing conveyong line valve that minimises product degradation.
The attack or sweep angle
of the blades is generally much more severe than it is with most conventional broadheads.
The in-plane curvature of the wing considerably reduces the aerodynamic drag especially in the transonic regime where the nonuniform distribution of the sweep angle
of the curved wing leads to a reduction in the wave drag effects.
