Download or read book Techniques for Measuring Liquid Water Content Along a Trajectory written by Rosemary M. Dyer and published by . This book was released on 1981 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard procedure for estimating the point value of liquid water content (M) along the reentry path of a ballistic missile is to use a radar derived value of radar reflectivity factor (Z), with the M to Z relation obtained from aircraft measurements of the particle spectrum. This report contains descriptions of the various techniques used to make the radar and aircraft data compatible. The results of various methods to predict the liquid water content values are compared with aircraft measured values. The extrapolation of instrumentally truncated aircraft measurements to include the entire range of particle sizes is treated in Section 1. Section 2 contains a discussion of the method of deriving nominal M-Z relations, applies the method to data acquired at Kwajalein Missile Range, and provides M-Z relations for rain, small snow, large snow, and bullet rosettes. The introduction of the factor 'k' to convert from aircraft measurements to radar derived values is also discussed in Section 2. The relationship of k with altitude and temperature for data from Kwajalein and Wallops Island is covered in Section 3. Finally, Section 4 contains a determination of the accuracy to which liquid water content can be estimated from climatological storm data for moderate to heavy stratiform winter storms at Wallops Island. The results of Section 4 demonstrate that situations which deviate significantly from climatological averages still require time- specific M-Z relations derived from simultaneous aircraft-radar measurements.

This book was released on 1954 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: The angle of inclination of the principal axis was found to have probable error of plus or minus 0.17 degrees both from analysis of the error of inertia measurement of the full-scale airplane and from tests with a model having a simple configuration. Analysis showed the probable error of the inertia measurements for the test airplane to be plus or minus1.00, plus or minus 0.49, and plus or minus 0.35 percent of the true moment of inertia about the X, Y, and Z body reference axes, respectively.
