Book excerpt: An investigation has been conducted in the NASA Langley 20-Foot Vertical Spin Tunnel to determine the static aerodynamic characteristics of a 1/25-scale model of the X-29A Forward Swept Wing airplane. The tests were conducted at a free-stream dynamic pressure of 3.6 lb/ft(exp 2), corresponding to a unit Reynolds number of 0.35x10(exp 6)/ ft, or 45x10(exp 5) based on a maximum fuselage forebody depth of 0.128ft. The purpose of this investigation was to assess the ability of various forebody devices to correct the aerodynamic parameters that are important in spin testing for Reynolds number effects. Low Reynolds number aerodynamic characteristics obtained for the X-29A during the present test were compared with high Reynolds number data obtained for this configuration in a previous test. The low Reynolds number tests were conducted first with the unmodified (baseline) model and then repeated with each of several forebody modifications installed.

Available in PDF, EPUB and Kindle. Book excerpt: state of the art in aeronautical engineering has been continually accelerated by the development of advanced analysis and design tools. Used in the early design stages for aircraft and spacecraft, these methods have provided a fundamental understanding of physical phenomena and enabled designers to predict and analyze critical characteristics of new vehicles, including the capability to control or modify unsatisfactory behavior. For example, the relatively recent emergence and routine use of extremely power- ful digital computer hardware and software has had a major impact on design capabilities and procedures. Sophisticated new airflow measurement and visualization systems permit the analyst to conduct micro- and macro-studies of properties within flow fields on and off the surfaces of models in advanced wind tunnels. Trade studies of the most efficient geometrical shapes for aircraft can be conducted with blazing speed within a broad scope of integrated technical disciplines, and the use of sophisticated piloted simulators in the vehicle development process permits the most important segment of operations—the human pilot—to make early assessments of the acceptability of the vehicle for its intended mission. Knowledgeable applica- tions of these tools of the trade dramatically reduce risk and redesign, and increase the marketability and safety of new aerospace vehicles.

Book excerpt: A program was conducted to obtain data, both steady state and dynamic, from wind tunnel models and full scale flight tests of the RA-5C aircraft. Data were acquired on 0.228 and 0. 125 scale RA-5C inlet models and on a fully instrumented flight test RA-5C aircraft. Interim data reports presenting the data acquired during each test have been published. These data were utilized in this report to develop scaling techniques for correlating small scale model wind tunnel data with full scale flight data. Data presented include duct steady state operating characteristics and pressure distributions in the inlet and at the engine face. Dynamic data are presented in the form of engine face turbulence contour plots, radial turbulence distributions and selected spectral data functions. Data are presented for variations of angle of attack, angle of yaw, Reynolds number, ramp angle, secondary flow rates and inlet diverter width. Brief descriptions of the model and test methods are also presented.
