Book Description
The effect of Mach number on both unshielded and shielded tubes was found to be considerable. For most of the unshielded tubes the usable range increased with Mach number, whereas that of the shielded tubes decreased with Mach number.

Book Description
Calibrations of 39 total-pressure tubes for an angle-of-attack range of plus or minus 45 degrees and an indicated airspeed of the various tubes differed as regards external shape, internal shape, and type of total-pressure entry. External shapes testsed included cylindrical-, conical-, and ogival-nose sections. Internal shapes and total-pressure entries were varied on the basis of such factors as size of impact opening, leading-edge sharpness, chamber shape, internal bevel, slant profile, and shielding (combined with venting). The effect of these design variables on the sensitivity of the tubes to angle of attack is discussed.

Book Description
The National Advisory Committee for Aeronautics is investigating the possibility of designing a fixed total-pressure tube which will remain insensitive to inclination of the air stream over a wide range of angle of attack throughout the subsonic and supersonic speed ranges. As the first step in this program the variation of total-pressure error with angle of attack of 39 total-pressure tubes has been determined for an angle-of-attack range of + or - 45 deg and an indicated airspeed of 195 miles per hour. The design of these tubes was varied in such a manner that the effects of external shape, internal shape, and configuration of the total- pressure entry could be determined. The external shapes tested included cylindrical-, conical-, and ogival-nose sections. The internal shapes and total-pressure entries were varied on the basis of such factors as size of impact opening, shape of internal chamber, internal bevel, leading-edge sharpness, slant profile, and shielding (combined with venting).
