An examination was made of the utilization of the effective moment parameter, that has been used for many years, in relation to a recently devised procedure that involves the concept of an effective angle of attack for the nonlinear motion history being analyzed. This procedure provides an approximate direct relationship between an effective moment parameter measurement and its parent nonlinear moment curve, for a large family of nonlinearities. Both the additional use of the effective moment parameter values and the restraints in their utilization are discussed in relation to small amplitude, large amplitude, and out-of-plane modes of testing.

Download Flight Stability and Automatic Control Book in PDF, ePub and Kindle
The second edition of Flight Stability and Automatic Control presents an organized introduction to the useful and relevant topics necessary for a flight stability and controls course. Not only is this text presented at the appropriate mathematical level, it also features standard terminology and nomenclature, along with expanded coverage of classical control theory, autopilot designs, and modern control theory. Through the use of extensive examples, problems, and historical notes, author Robert Nelson develops a concise and vital text for aircraft flight stability and control or flight dynamics courses.

Download Evaluation of Critical Sting Length on a 7-deg Cone as Determined by Measurements of Dynamic Stability Derivatives and Base Pressure for Mach Numbers 0.2 Through 1.3 Book in PDF, ePub and Kindle
Wind tunnel tests were conducted to provide sting-support interference information for planning and directing wind tunnel tests at subsonic and transonic Mach numbers. Sting-length effects on dynamic stability derivatives, static pitching moment, and base pressure of a blunt, flat-base 7- deg cone were investigated at Mach numbers 0.2 to 1.3 in the Arnold Engineering Development Center (AEDC) Propulsion Wind Tunnel Facility (PWT). Two frequencies of oscillation, nominally 5.3 and 2.9 Hz, were investigated. The boundary-layer state at the model base was turbulent for all Mach numbers greater than 0.2. The interference effects of two types of model-wake splitter plates were also investigated. The results showed that the critical sting length depended on the Mach number, angle of attack, and type of data used as the interference indicator. A critical sting length of three model diameters was determined to be suitable for all test conditions for the ratio of sting-diameter-to-model-base- diameter (0.22) for this test.
