National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

V/STOL Flight Test Instrumentation Requirements for Extraction of Aerodynamic Coefficients. Volume I.

AD850956

Publication Date	1968
Personal Author	Hill, R. W.; Clinkenbeard, I. L.; Bolling, N. F.
Page Count	326
Abstract	The results of a synthesis of pertinent maneuvers with a mathematical model of the XC-142 v/stol airplane have served to establish tolerances in the measurement of flight parameters which provide the time histories used in the derivation of aerodynamic coefficients. The method of multiple linear regression, a least squares algorithm, provides the requisite mathematical tool with adequate statistical credentials. A state-of-the-art survey and a vendor-product-line review have provided guidelines for a system that will meet the overall accuracy requirements established.
