Download Aerodynamic Characteristics of a Small-Scale Shrouded Propeller at Angles of Attack from 0 Deg to 90 Deg Book in PDF, Epub and Kindle
An investigation has been made to determine the effects of airspeed and angle of attack on the lift, drag, and pitching moment of a shrouded-propeller model, having a shroud length of about two-thirds the propeller diameter, over an angle-of-attack range from 0 deg to 90 deg. Tests were made of the complete model with the propeller operating and also of the shroud and motor combination with the propeller removed. The effect of inlet-lip cross-sectional radius on the static-thrust characteristics was also studied. These tests were made in connection with the design of a vertical-take-off free-flight model and the results are presented herein without analysis as it is felt that they may be useful in the design or analysis of other aircraft.

Download Investigation of the Aerodynamic Characteristics of a Model Wing-propeller Combination and of the Wing and Propeller Separately at Angles of Attack Up to 90° Book in PDF, Epub and Kindle
This report presents the results of an investigation conducted in the Langley 300 mph 7- 10-foot wind tunnel for the purpose of determining the aerodynamic characteristics of a model wing-propeller combination, and of the wing and propeller separately at angles of attack up to 90 degrees. The tests covered thrust coefficients corresponding to free-stream velocities from zero forward speed to the normal range of cruising speeds. The results indicate that increasing the thrust coefficient increases the angle of attack for maximum lift and greatly diminishes the usual reduction in lift above the angle of attack for maximum lift.

Download Progress in Aeronautical Sciences Book in PDF, Epub and Kindle
Progress in Aeronautical Sciences, Volume 3 deals with topics in the field of aerodynamics. The book covers topics on aerodynamic design, propulsion systems, hypersonic flows laboratories, and gust research. The text is composed of four articles. The first article presents a review of the aspects of aerodynamic design of swept-winged aircraft. The second paper surveys the applications of ducted propellers. Critical reviews of experimental hypersonic facilities are provided in Chapter 3. The last paper focuses on the meteorological and aeronautical aspects of atmospheric turbulence. Aeronautical engineers, pilots, aviators, and students in the field of aerodynamic design will find this book invaluable.

Download Robot 2019: Fourth Iberian Robotics Conference Book in PDF, Epub and Kindle
This book gathers a selection of papers presented at ROBOT 2019 – the Fourth Iberian Robotics Conference, held in Porto, Portugal, on November 20th–22nd, 2019. ROBOT 2019 is part of a series of conferences jointly organized by the SPR – Sociedade Portuguesa de Robótica (Portuguese Society for Robotics) and SEIDROB – Sociedad Española para la Investigación y Desarrollo en Robótica (Spanish Society for Research and Development in Robotics). ROBOT 2019 built upon several previous successful events, including three biannual workshops and the three previous installments of the Iberian Robotics Conference, and chiefly focused on presenting the latest findings and applications in robotics from the Iberian Peninsula, although the event was also open to research and researchers from other countries. The event featured five plenary talks on state-of-the-art topics and 16 special sessions, plus a main/general robotics track. In total, after a stringent review process, 112 high-quality papers written by authors from 24 countries were selected for publication.

Download Experimental Investigation of the Effects of Some Shroud Design Variables on the Static Thrust Characteristics of a Small-scale Shrouded Propeller Submerged in a Wing Book in PDF, Epub and Kindle
An experimental investigation has been made to determine the effects of shroud-lip radius of curvature, shroud length, and shroud diffuser angle on the static thrust characteristics of a small-scale shrouded propeller which simulated a propeller submerged in the wing of an airplane. Also included are the effects of distance from the exit of the shroud to the ground on the thrust available take-off.
