Tip Of The Blade

Tip of the Blade: Notes on Rowing is a collection of over 100 articles by sculling coach and Rowing magazine columnist, Marlene Royle. Each piece offers a hands-on, practical approach toward improving your understanding of the sport of rowing. Ranging from your first outing in a shell to steering a perfect race, the topics covered in nine chapters include: flexibility, breathing, posture, core strengthening, coordination, skill development, aerobic conditioning, recovery, oarsmanship, sweep and sculling technique, rhythm, boat stability, bladework, performance drills, self-coaching, mental training, event planning, starts, sprinting, head-style events, marathoning, rigging, erging, and coaching. Whether you are a trainer planning the fall season for your novice squad, a competitive sculler who needs to improve stroke length, or a recreational rower looking to gain more fluidity, this anthology has valuable information to help you develop your technique, methods, and results.

Author R.J. Martin, whose knives are some of the most popular and sought-after in the industry, instructs on flat- and double-hollow-grinding knife blades. Martin been featured in BLADE® Magazine with increasing frequency, and here’s your chance to learn his methods for blade grinding. You won’t be disappointed.

Blade Element Rotor Theory This book presents an extension of the conventional blade element rotor theory to describe the dynamic properties of helicopter rotors. The presented theory focuses on the accurate mathematical determination of the forces and moments by which a rotor affects its rotorcraft at specified flight conditions and control positions. Analyzing the impact of a blade's non-uniform properties, the book covers blade twisting, the non-rectangular planform shape of a blade, and inhomogeneous airfoil along the blade. It discusses inhomogeneous induced airflow around a rotor disc in terms of the blade element rotor theory. This book also considers the impact of flapping hinge offset on the rotor's dynamic properties. Features • Focuses on a comprehensive description and accurate determination of the rotor's aerodynamic properties • Presents precise helicopter rotor properties with inhomogeneous aerodynamic properties of rotor blades • Considers inhomogeneous distribution of induced flow • Discusses a mathematical model of a main helicopter rotor for a helicopter flight simulator This book is intended for graduate students and researchers studying rotor dynamics and helicopter flight dynamics

A water-cooled turbine was fabricated and tested to determine the effect of a connecting passage at the turbine rotor blade tip between a radial coolant passage 0.10 inch in diameter (length-diameter ratio = 25.5) and radial coolant passages in the legnth-diameter range of 5.1 to 20.4. Coolant flow through the connecting passage is induced by free-convection forces in the radial passages.
