Abstract
Official abstract text for this publication.
A method of forming a pitot tube includes forming a substantially cylindrical body portion including an outer surface, a tip portion having an inlet opening and an interior defining a flow passage, radially tapering the outer surface from the body portion toward the inlet opening, and disposing at least one electrical coil including one or more coil wraps along the flow passage of the pitot tube.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of forming a pitot tube comprising: forming a substantially cylindrical body portion including an outer surface, a tip portion having an inlet opening, and an interior defining a flow passage; radially tapering the outer surface from the body portion toward the inlet opening; disposing at least one electrical coil that includes one or more coil wraps along the flow passage of the pitot tube; positioning at least one bulkhead along the flow passage to limit travel of particles ingested into the pitot tube; and arranging at least one of the one or more coil wraps along the flow path downstream of the at least one bulkhead. 2. The method of claim 1 , wherein the radially tapered outer surface has a concave curve. 3. The method of claim 1 , wherein disposing the at least one electrical coil includes arranging the one or more coil wraps to establish a variable watt density along the flow path. 4. The method of claim 1 , further comprising: arranging at least one of the one or more coil wraps along the flow path between the inlet opening and the at least one bulkhead. 5. A method of forming a pitot tube comprising: forming a substantially cylindrical body portion including an outer surface, a tip portion having an inlet opening, and an interior defining a flow passage; radially tapering the outer surface from the body portion toward the inlet opening; disposing at least one electrical coil including one or more coil wraps along the flow passage of the pitot tube; positioning at least one bulkhead along the flow passage to limit travel of particles ingested into the pitot tube; and forming at least one drain opening in the substantially cylindrical body portion fluidically connecting the flow path and the outer surface; wherein positioning the at least one bulkhead along the flow passage includes positioning at least a first bulkhead along the flow passage and a second bulkhead along the flow passage downstream of the first bulkhead, the second bulkhead defining an aft most bulkhead. 6. The method of claim 5 , wherein forming the at least one drain opening includes forming the at least one drain opening upstream of the at least one bulkhead. 7. The method of claim 6 , wherein forming the at least one drain opening upstream of the at least one bulkhead includes positioning the at least one drain opening between one of the one or more coil wraps and the at least one bulkhead. 8. The method of claim 5 , wherein positioning the at least one drain opening includes arranging the at least one drain opening upstream of the aft most builkhead. 9. The method of claim 8 , wherein arranging the at least one drain opening upstream of the aft most builkhead includes arranging the at least one drain opening directly adjacent the aft most bulkhead. 10. The method of claim 8 , wherein arranging the at least one drain opening upstream of the at least one bulkhead includes positioning the at least one drain opening between one of the one or more coil wraps and the aft most bulkhead. 11. The method of claim 10 , wherein positioning the at least one drain opening between one of the one or more coil wraps and the aft most bulkhead includes arranging the at least one drain opening directly adjacent the aft most bulkhead.
