A fan structure includes a fan frame having a base and a shaft barren vertically upward extended from the base; a motor stator enclosure having a top provided with a shaft hole and an open bottom correspondingly covering and connecting to a top of the base, such that the motor stator enclosure, the shaft barrel and the base together define a potting space among them; a potting opening selectively provided on the base or the motor stator enclosure to communicate with the potting space; a motor stator externally fitted around the shaft barrel and located in the potting space; and a potting compound filled in the potting space to cover the motor stator. With the above arrangements, the fan structure overcomes the problem in conventional inconvenient fan potting process to largely reduce production costs, production time, bad yield rate, and reworking.

Disclosed herein is an all-in-one methodology for the fabrication and the programming of soft machines. Instead of relying on the assembly of individual parts, the disclosed approach harnesses interfacial flows in elastomers that progressively cure to robustly produce monolithic pneumatic actuators whose shape can easily be tailored to suit applications ranging from artificial muscles to grippers. Rationalized herein are the fluid mechanics at play in the assembly of the disclosed actuators and modeled herein are their subsequent morphing. This quantitative knowledge was leveraged to program these soft machines and produce complex functionalities, for example sequential motion obtained from a monotonic stimulus. It is expected that the flexibility, robustness, and predictive nature of the disclosed methodology will accelerate the proliferation of soft robotics by enabling the assembly of complex actuators, for example long, tortuous, or vascular structures, thereby paving the way towards new functionalities stemming from geometric and material nonlinearities.

A method of manufacturing a woven fabric for a composite component for a turbine engine. The method includes arranging a plurality of warp fiber tows to extend in the warp direction.
