A convertible ducted fan engine and mounting system. The convertible ducted fan engine has a shroud encircling a mechanical fan. The convertible ducted fan engine includes a fluid-propulsion configuration in which the mechanical fan rotates freely with respect to the shroud to produce thrust through fluid flow, and a drive-wheel configuration in which the shroud rotates about the rotational axis. The mounting system includes at least one gimbal ring and may include a circular track system thereby enabling the convertible engine to be oriented in any direction.

A self-rotation graphene heat-dissipation device for a direct-drive electro-hydrostatic actuator, that includes inner and outer walls of a shell eccentrically arranged relative to each other, the shell sleeves on an outer side of a self-rotation mechanism. The self-rotation mechanism is arranged on an outer side of a shaft; the shaft is coaxial with the inner wall of the shell and connected with outer and inner end covers. The self-rotation mechanism includes a rotor and blades, the rotor sleeves on the shaft and is connected with the outer and inner end covers. The rotor is slidably connected with the blades, and outer walls of the blades are closely attached to the inner wall of the shell. Graphene heat-dissipation layers are coated on outer walls of all of the shell, blades, the rotor, the inner and outer end covers respectively.

A tower fan is provided that includes a fan body having a double cross fan blower centered in the body of the fan with a motor positioned between the fan blowers in the center of the fan body. The tower fan is capable of being oriented in both the horizontal and vertical directions. The fan body may further include first and second ends and at least two supports. At least a first support is coupled to the first end of the fan body and a second support is removably coupled to the least second end of the fan body. The first and second ends of the fan body each have a groove for each receiving at least one of the at least two support members where each groove extends entirely around the fan body. The at least two supports may both be removably coupled to the fan body or one of the at least two supports may be permanently coupled to the first end of the fan body.

A magnetically attracted fan set comprises N+1 fans, the N≥1, and each of the N+1 fans has a fan frame and an airflow generating component disposed on the fan frame. Any two adjacent fans of the N+1 fans respectively have a joint surface, each of the joint surfaces has at least one fixing member capable of forming magnetic attraction, when the joint surface is close to the other joint surface at a distance sufficient for the two fixing members on the two joint surfaces to form magnetic attraction, two of the N+1 fans are joined together. Accordingly, the invention is capable of directly and quickly joining the N+1 fans without requiring complicated assembly gestures or other external components.

A bottom-mounted whole house fan assembly includes an intake plenum mounted over an opening in a ceiling of a building. The intake plenum is supported on the ceiling in the attic of the building. One end of a flexible duct is connected to the intake plenum and the other end of the duct is connected to a fan so that the fan draws air in the building through the intake plenum and duct and exhausts the air in the attic from whence the air is vented to atmosphere. The fan is supported by at least one vertical strut that is connected to the ceiling at the lower end of the strut and to a housing of the fan at the upper end of the strut. A sound dampener is interposed between the strut and the fan housing and/or the ceiling beam to which the strut is attached.

A fan carrier is to be placed in physical communication with a fan-side connector of an information handling system. The fan carrier includes a plunger assembly and multiple isolators. The plunger assembly is biased toward an at-rest position. The plunger assembly is in physical communication with the fan-side connector when the plunger assembly is in a deformed position. The isolators are mounted on the fan carrier, and dampen vibration energy in the fan carrier and prevent the vibration energy from being transferred to the fan-side connector. The isolators enable the fan-side connector to float within the fan carrier.

A fan includes a column assembly, a fan head, a hinge assembly, and a support structure connected to the fan head and the column assembly. The hinge assembly includes a first connection member and a second connection member which are hinge-connected to each other. The first connection member is connected to the column assembly, and the second connection member is connected to the fan head. The fan head is configured to rotate around the support structure, and an axis around which the fan head rotates relative to the support structure coincides with an axis around which the first connection member and the second connection member rotate relative to each other.

A suspension assembly of industrial fans is provided. The suspension assembly of industrial fans includes a suspending main rod and a sub rod. A first adapter is pivotally disposed on a bottom end of the suspension main rod and provided with a plurality of first assembly holes. One end of the sub rod corresponding to the first adapter is pivotally connected with a second adapter which includes second assembly holes corresponding to the first assembly holes. A fan body is installed at the other end of the sub rod. According to environmental requirements and wind field coverage, directions and angles of air flows from the fan body can be changed by adjustment of relative positions of the second assembly holes of the second adapter to the first adapter. Therefore, good air circulation and ventilation in the environment is provided.

A clip-on fan includes a specialized clamping clip that is attached to rectangular or cylindrical tent poles that are commonly used for grow tents; wherein fans are essential components for growing in tents and the current designs clip-on fans do not meet the needs of indoor growers; the clip-on fan comprising a fan assemblage and clip clasp assemblage arranged at the base of the complete product, wherein the clip is able to grasp to the vertical tubular structure of a grow tent; the grasping clasp assembly consisting of: a left clip plate, a right clip plate, a clip plate rotation shaft, a clip spring, a fan connection hole and, a clip clamp opening; the left and right clip plates are connected in a bilateral symmetry through the clip plate rotation shaft at the central connection position.

A method for forming a blade for a gas turbine engine may include forming a suction side sheath and a pressure side sheath, a first cavity and a second cavity established on opposed sides of a rib, forming a structural core configured for positioning in an interior section of the blade between the suction side sheath and the pressure side sheath, the structural core including a first core member, a second core member and a root interconnecting the first and second core members, assembling the suction side sheath and the pressure side sheath with the structural core such that the first core member is positioned in the first cavity and such that the second core member is positioned in the second cavity, and securing the suction side sheath to the pressure side sheath to form the blade.
