The Propeller Handbook: The Complete Reference for Choosing, Installing, and Understanding Boat Propellers
On the surface, choosing the correct propeller for a particular boat seems simple. But one factor affects another, which then affects another factor, leading many boaters to believe that propeller selection depends more on black magic than logic. All the questions are answered in this complete reference, the first of its kind. This clear, easy-to-use handbook for all small boats is written not for Ph.D.s seeking the latest wrinkle in high-tech propeller design, but as a practical aid for the average mechanic, engineer, boatbuilder, fleet operator, serious yachtsman, or naval architect. .

Dynamic Effects on Propeller Blade Section Lift, Drag, and Pitching Moment Coefficients
This is a NAVAL SURFACE WARFARE CENTER CARDEROCK DIV BETHESDA MD report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A313763. The abstract provided by the Pentagon follows: The Propeller Force Module (PFM) uses the blade element/momentum theory to predict propeller forces during maneuvers. A typical inflow angle distribution is studied. The blade sections will encounter spatial and temporal variations in angles of attack. Theories to calculate unsteady effects on section lift, drag, and pitching moment coefficients are formulated and presented in this report. Using the classic approach developed in aerodynamics, the section lift and pitching moment are expressed in circulatory and non- circulatory solutions. The non-circulatory solution is found to be a universal function independent of the type of motion. The circulatory solution depends heavily on the type of motion. In the case of ramp-up and ramp-down motions simulating blade sections experiencing angle of attack variations when maneuvering, an analytical solution is obtained for the circulatory lift. Empirical formula are developed to calculate the delay in stall angle due to unsteady motion. The classic aerodynamic theories assume the flow to be potential which give zero drag. Instead, Leishman's mathematical model assuming a loss of full suction pressure recovery at the leading edge due to viscous effect is adopted in this report to calculate the dynamic drag. The theories are compared with experimental measurements by Francis and Keesee, and by Ham and Garelick with encouraging results..

Aircraft And Rotorcraft System Identification: Engineering Methods With Flight-test Examples (Aiaa Education Series)
Although many books have been written on the theory of system identification, few are available that provide a complete engineering treatment of system identification and how to successfully apply it to flight vehicles. This book provides the unique perspective of over 20 years of flight-test applications to both aircraft and rotorcraft and is a valuable resource for students, working engineers, and others interested in atmospheric flight mechanics, modeling and simulation, and test and evaluation. It presents proven methods, practical guidelines, and real-world flight-test results for a wide range of state-of-the-art flight vehicles, from small uncrewed aerial vehicles (UAVs) to large manned aircraft/rotorcraft. Beginning with the basic concepts of system identification, each chapter traces a simple simulation example and real flight examples through the step-by-step process from instrumentation and data checking to model extraction and model verification. The frequency-response method, that is unique to this book, is especially well suited for system identification of aircraft and rotorcraft dynamics models from flight-test data. A complete chapter is devoted to higher-order modeling of helicopters. Many applications are included to demonstrate how the products resulting from system identification are used. Specific applications include flight mechanics and handling-qualities analyses, stability margin determination, structural mode determination, and simulation model fidelity assessment. The book assumes knowledge of the basic concepts of aeronautics, Laplace transforms, and flight dynamics and classical control. Emphasis is placed on engineering methods and interpretation of flight-test results and each key method or analysis application is illustrated with graphics obtained from the system identification software (CIFERÆ) provided with the book. Case studies based on real flight-test projects are included as well! as problems for students to solve using the provided CIFERÆ software. A Solutions Manual, written by Christina M. Ivler and Mark B. Tischler is available from the publisher..

Convair Twins (AirlinerTech Series, Vol. 12)
World War II saw a tremendous number of advances in aviation technology. Low-speed maneuverability, robust pressurization systems, and implementation of the first jet engines are just a few of the amazing developments made. Returning GIs, having experienced air travel to distant lands, were expected to fuel a postwar travel boom. That perceived need drove companies such as Consolidated Vultee Airlines (Convair) to propose a new series of medium-range airliners, thus giving birth to the Convair-Liner and their turboprop-powered conversions - the Turbo-Liner. More than 55 years after the first flight of the Convair-Liner, turboprop-powered examples of the type are still hauling cargo in the United States and passengers in a few foreign countries. This book discusses the development of the Convair Twins and their eventual transition from piston power to turboprop power. Over 300 photos illustrate Convair Twins' interior, exterior, powerplants, and systems. Find out who the initial delivery customers of the 240, 340, and 440 were. This book covers the many challenges Convair faced and the technologies employed to advance it. Also covered are military models, domestic and foreign airline operators and models flown, second airline owners, and significant dates in Convair-Liner history. .
