Book Data from a Static thrust Investigation of a Large scale General Research Vtol stol Model in Ground Effect

Download or read book Data from a Static thrust Investigation of a Large scale General Research Vtol stol Model in Ground Effect written by Robert J. Huston and published by . This book was released on 1960 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The model was tested at two different elevations with the wing pivot at 1.008 and 2.425 propeller diameters above the ground. The slipstream of the propellers was deflected by tilting the wing and propellers, by deflections of large-chord trailing-edge flaps, and by combinations of flap deflection and wing tilt. Tests were conducted over a range of propeller disk loadings from 7.41 to 29.70 pounds per square foot. Force data for the complete model and pressure distributions for the wing and flaps behind one propeller were recorded and are presented in tabular form without analysis.

Book Further Measurements of Model Propeller Pressure Distributions Using a Novel Technique

Download or read book Further Measurements of Model Propeller Pressure Distributions Using a Novel Technique written by Stuart D. Jessup and published by . This book was released on 1986 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model propeller blade pressure distributions were measured using a novel technique. A single pressure gage was installed at a radial position to measure pressures at numerous chordwise locations through pressure taps and connecting channels. The technique resulted in accurate, detailed pressure distributions along two radial positions using two pressure gages. The major advantage of this technique is the ability to make measurements in the thin parts of the blade with high potential accuracy, and no disruption to the measuring surface, except for the orifice hole. The relatively along test time required to collect the data is the disadvantage. Keywords: Marine Propeller, Propeller Research Pressure Distribution, Model Experiments.

Book Aerodynamic Characteristics of a Powered Semispan Tilting shrouded propeller VTOL Model in Hovering and Transition Flight

Download or read book Aerodynamic Characteristics of a Powered Semispan Tilting shrouded propeller VTOL Model in Hovering and Transition Flight written by Kenneth W. Goodson and published by . This book was released on 1962 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An investigation of the aerodynamic characteristics of a powered semispan tilting-shrouded-propeller configuration has been conducted in the 17-foot test section of the Langley 300-MPH 7- by 10-foot tunnel. The wing had an aspect ratio of 2.67 (based on wing span of 60 inches), a taper ratio of 0.67, and an NACA 2418 airfoil section with a 15-inch-diameter shrouded propeller mounted on the tip. The test results show that large nose-up pitching moments are obtained at transitional speeds of about 40 knots and duct angle of about 70°. Decelerating flight procedures further increases in the nose-up moment. Ground proximity reduces the nose-up pitching moments. The large nose-up moments can be trimmed by use of duct-exit control vanes. The results show that unloading the duct (shroud) by flying at a wing angle of attack of 15° reduces the power required by about 30 percent at 50 knots. Duct-lip stall produces large increases in power required. The results in general show that full-scale aerodynamic simulation can be made with small-scale wind-tunnel models if duct-lip separation at low Reynolds numbers is avoided."--Summary.
