Book Fan and Wing Force Data from Wind tunnel Investgation of a 0 38 meter  15 IN   Diameter VTOL Model Lift Fan Installed in a Two dimensional Wing

Download or read book Fan and Wing Force Data from Wind tunnel Investgation of a 0 38 meter 15 IN Diameter VTOL Model Lift Fan Installed in a Two dimensional Wing written by Joseph A. Yuska and published by . This book was released on 1972 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test data are presented for a 38-cm (15-in.) diameter, 1.28 pressure ratio model VTOL lift fan installed in a two-dimensional wing and tested in a 2.74-by 4.58-meter (9-by 15-ft)V/STOL wind tunnel. Tests were run with and without exit louvers over a wide range of crossflow velocities and wing angle of attack. Tests were also performed with annular-inlet vanes, inlet bell-mouth surface disconuities, and fences to induce fan windmilling. Data are presented on the axial force of the fan assembly and overall wing forces and moments as measured on force balances for various static and crossflow test conditions. Midspan wing surface pressure coefficient data are also given.

Book Results of Wind Tunnel Tests of a Full scale  Wing mounted  Tip turbine driven Lift Fan

Download or read book Results of Wind Tunnel Tests of a Full scale Wing mounted Tip turbine driven Lift Fan written by GENERAL ELECTRIC CO CINCINNATI OHIO. and published by . This book was released on 1963 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: The full-scale wing-tip turbine-driven lift fan was model tested in the NASA Ames Research Center 40-foot by 80-foot wind tunnel. This series of tests has provided the first large scale test data with fans installed in wings. Detailed discussions and tabular data are pre sented on the following: wind tunnel model; test instrumentation, and test procedures and results. Analysis of results considers the basic aircraft performance (power off), fan aerodynamic performance, fan thermodynamic per formance, fan powered aircraft performance, fan mechanical performance and hardware inspection.

Book A Wind tunnel Investigation of the Development of Lift on Wings in Accelerated Longitudinal Motion

Download or read book A Wind tunnel Investigation of the Development of Lift on Wings in Accelerated Longitudinal Motion written by Thomas R. Turner and published by . This book was released on 1956 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: All the wings investigated developed at least 90 percent of their steady-state lift in the first 7 chord lengths of travel. The development of lift was essentially independent of the acceleration when based on chord lengths traveled, and was in qualitative agreement with theory.

Book Aerodynamic Characteristics of a Large scale Model a Lift Fan Mounted in a 5 percent thick Triangular Wing  Including the Effects of BLC on the Lift fan Inlet

Download or read book Aerodynamic Characteristics of a Large scale Model a Lift Fan Mounted in a 5 percent thick Triangular Wing Including the Effects of BLC on the Lift fan Inlet written by Brent K. Hodder and published by . This book was released on 1970 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The low-speed aerodynamics of a large-scale triangular wing model, with a reduced thickness, tip-turbine driven lift fan in each wing were investigated in the Ames 40-by 80-Foot Wind Tunnel. The model had a 5-percent-thick wing typical of wings designed for supersonic performance. Conventional lift-fan depth has, in the past, limited wing thickness to about 10 percent. A thinner lift fan for the present investigation was obtained by modification of a conventional fan. The modification included removing the discharge stator and reducing the fan inlet length and radius. To control airflow separation resulting from small inlet radii, blowing boundary-layer control was applied through a nozzle in the inlet. Performance of the modified fan along with aerodynamic characteristics of the total configuration is presented. The static thrust performance of the conventional fan (requiring a lo-percent wing) was equalled by the reduced thickness fans of this investigation.--P. [i].

Book An Investigation of Several Slotted Wind Tunnel Wall Configurations with a High Disk Loading V STOL Model

Download or read book An Investigation of Several Slotted Wind Tunnel Wall Configurations with a High Disk Loading V STOL Model written by Travis W. Binion and published by . This book was released on 1971 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation reported herein is the experimental portion of a unified theoretical and experimental search for a slotted wind tunnel wall configuration with minimal interference for conventional and V/STOL models. It is shown that theory and experiment are in excellent agreement for the classical case provided an appropriate expression is used to relate the wall geometry to the boundary condition. Classical data correction equations are not appropriate for the V/STOL case, however. An additional term, not predicted by theory, is needed to account for changes in the jet wake. Geometric parameters which influence the wall interference quantities are indicated. Wall configurations are shown which will produce interference-free force data to a jet-to-free-stream velocity ratio of 4.5. (Author).
