Effects of planform geometry on hover performance of a 2-meter-diameter model of a four-bladed rotor
Hover tests were conducted on three small scale rotors to evaluate the effects of blade planform taper on rotor hover performance. Tests were conducted on a rectangular swept-tip configuration, on a configuration with a 3 to 1 taper over the outboard 20 percent of the span, and on a configuration with a 5 to 1 taper over the outboard 20 percent of the blade span. The investigation covered a range of thrust coefficients from 0 to 0.0075 and a range of tip speeds from 300 to 600 ft/sec. The tests showed that both tapered configurations had better hover performance than the swept-tip rectangular configuration and that the 3 to 1 taper configuration was better than the 5 to 1 taper configuration. The test results were compared with predictions made with a prescribed wake analysis, a momentum analysis, and a simplified free wake analysis
Frank\u27s Arms: Stories & Lessons from a Caregiver and Patient Advocate
Frank\u27s Arms follows a caregiver\u27s journey through terminal illness into widowhood. Tragic, yet empowering and hopeful, the author\u27s stories are interlaced with compassion, honor, dignity, and dedication. This thought-provoking memoir is filled with insights on advocacy and self-discovery.https://griffinshare.fontbonne.edu/faculty-books/1017/thumbnail.jp
A Practical Method of Policy Analysis by Estimating Effect Size
The previous articles on class size and other productivity research paint a complex and confusing picture of the relationship between policy variables and student achievement. Missing is a conceptual scheme capable of combining the seemingly unrelated research and dissimilar estimates of effect size into a unified structure for policy analysis and decision making. This article builds a rationale for a unifying structure and consistent method of estimating effect size
Helicopter Anti-Torque System Using Strakes
A helicopter is disclosed with a system for controlling main-rotor torque which reduces the power and size requirements of conventional anti-torque means. The torque countering forces are generated by disrupting the main rotor downwash flowing around the fuselage. The downwash flow is separated from the fuselage surface by a strake positioned at a specified location on the fuselage. This location is determined by the particular helicopter wash pattern and fuselage configuration, generally being located between 20 deg before top dead center (TDC) and 80 deg from TDC on the fuselage side to which the main rotor blade approaches during rotation. The strake extends along the fuselage from the cabin section to the aft end and can be continuous or separated for aerodynamic surfaces such as a horizontal stabilizer

Another Look at the Glass and Smith Study on Class Size
One of the most influential studies affecting educational policy is Glass and Smith’s 1978 study, Meta-Analysis of Research on the Relationship of Class Size and Achievement. Since its publication, educational policymakers have referenced it frequently as the justification for reducing class size
Optimizing Educational Resources: A Paradigm for the Pursuit of Educational Productivity
The advantage and perhaps the major motivation for using “seat-of-the-pants” decision making is that it obscures the assumptions made in arriving at a decision. If no one knows the assumptions upon which you based your decisions, then even though they may be uneasy with the decision they will have a difficult time criticizing your assumptions or decisions
