Abstract
A fan installation assembly includes a conduit and an axial fan assembly. The conduit is disposed onboard a vehicle and configured to contain airflow that is supplied to or received from an internal cabin of the vehicle. The axial fan assembly is configured to propel the airflow through the conduit. The axial fan assembly includes a case, a motor assembly, and an impeller. The case surrounds the impeller and the motor assembly and is mounted to the conduit. The impeller includes a hub and multiple blades mounted on the hub. Each of the blades has a toroidal shape and forms a loop.
Claims20
A fan installation assembly comprising:
- a conduit disposed onboard a vehicle and configured to contain airflow that is supplied to or received from an internal cabin of the vehicle;
- and
- an axial fan assembly configured to propel the airflow through the conduit, wherein the axial fan assembly comprises a case, a motor assembly, and an impeller, wherein the case surrounds the impeller and the motor assembly and is mounted to the conduit, wherein the impeller includes a hub and multiple blades mounted on the hub, and wherein each of the blades has a toroidal shape that forms a loop.
An aircraft comprising:
- an air distribution system including a conduit and an axial fan assembly, wherein the conduit is configured to contain airflow that is supplied to or received from an internal cabin of the aircraft, wherein the axial fan assembly is configured to propel the airflow through the conduit, and wherein the axial fan assembly comprises:
- a motor assembly;
- an impeller including a hub and multiple blades mounted on the hub, wherein each of the blades has a toroidal shape that forms a loop;
- and
- a case that is mounted to the conduit and surrounds the impeller and the motor assembly.
A fan installation assembly comprising:
- a conduit disposed onboard a vehicle and configured to contain airflow that is supplied to or received from an internal cabin of the vehicle;
- and
- an axial fan assembly configured to propel the airflow through the conduit, wherein the axial fan assembly comprises a case, a motor assembly, and an impeller, wherein the case defines a cavity that is fluidly connected to an internal volume of the conduit, and wherein the impeller and the motor assembly are disposed within the cavity;
- wherein the impeller includes a hub and multiple blades mounted on the hub, wherein each of the blades has a toroidal shape and forms a loop, wherein each of the blades includes a first airfoil section mounted to the hub, a second airfoil section mounted to the hub, and a tip section that connects the first and second airfoil sections;
- and
- wherein the case defines an annular relief channel configured to receive captured flow of the airflow.
