The integral pin-fin tube is a new type of non-continuous finned tubes, increasing the effective heat transfer area, while its non-continuous fin structure can strongly stimulate the fluid boundary layer separation, to achieve enhanced heat transfer effect. Using fluent software three-dimensional numerical simulation on integral pin-fin tube is got. The results is accord to the actual situation, verifies...
In order to solve the problems of missile's safety and arming device identifying missile's overloading, that is the phenomena of "arming movement accumulating" of the untuned runaway escapement in collision experiments, and tooth breaking in impulsion experiments, when adopting setback arming device driven by single mass slider. This paper brings forward a principle of untuned runaway escapement...
Two image sensors simulate directly the way of disposition of biologic vision, and it is used in many fields, such as UAV detection, vehicle navigation, objects identify and so on. This paper focuses on the localization using multi-vision method (more than two image sensors can be used to achieve localization). For the special application, it has improved the original method which uses two image sensors,...
The MAV is very little, so it is easily disturbed by the environment and has week stability. Due to its low Reynolds number, it is easy to be affected by the unstable air (turbulence and gusts), and other outside interference. Recent work in dynamic inversion with neural network may be applied to control a MAV where the reference commands include position, velocity, attitude and angular rate. This...
The MAV accurate modes are typically unavailable. Most traditional methods for system design are complex and can not get satisfactory effect. Recent work in dynamic inversion with neural network may be applied to control a MAV where the reference commands include position, velocity, attitude and angular rate. This control technology can provide the MAV with an admirably command follow and steady control...
