Available in PDF, EPUB and Kindle. Book excerpt: This NASA special publication presents a general overview of the flight research that has been conducted at Ames Research Center over the last 57 years. Icing research, transonic model testing, aerodynamics, variable stability aircraft, boundary layer control, short takeoff and landing (STOL), vertical/ short takeoff and landing (V/STOL) and rotorcraft research are among the major topics of interest discussed. Flying qualities, stability and control, performance evaluations, gunsight tracking and guidance and control displays research are also presented. An epilogue is included which presents the significant contributions that came about as a result of research and development conducted at Ames. Flight research has been an integral and essential part of the missions of, first, the National Advisory Committee for Aeronautics (NACA) and, later, its successor, the National Aeronautics and Space Administration (NASA). The NACA's Ames Aeronautical Laboratory was established at Moffett Field, California, in 1939. In its role as an aeronautical research laboratory, Ames, from its inception, made the most of the linkage between exploratory and developmental testing in its wind tunnels and in flight. The research carried out in flight had numerous technical areas of emphasis over the years, and most of the individual experiments can be categorized accordingly. These areas are identified in the narrative to follow as icing research; transonic model testing; aerodynamics research; flying qualities, stability and control, and performance evaluation; variable stability aircraft; gunsight tracking and guidance and control displays; in-flight thrust reversing and steep approach research; boundary-layer control research; short takeoff and landing (STOL) and vertical and short takeoff and landing (V/STOL) aircraft research; and rotorcraft research. From the earliest days of Ames Aeronautical Laboratory until the creation of NASA, the focus of flight research was on military aircraft and their operations. Icing research and the earliest efforts in aerodynamics and flying qualities research occurred during World War II and were intended to aid in the design and operation of aircraft for the Army Air Corps and the Navy. From the war's end until the late 1950s, motivation for research came from the need to achieve ever higher performance and to advance the technology in wing aerodynamics. Upon the transition from the NACA to NASA, headquarters assigned Ames the responsibility for powered-lift research, including flight research with STOL and V/STOL aircraft. This decision was influenced by Ames' broad technical background with this category of aircraft in aerodynamics, performance, stability and control, flying qualities, and operations and because of the presence of the 40- by 80-foot wind tunnel and its experienced aerodynamics staff that had developed considerable expertise in powered-lift technology. Another influence on this decision was the interest the U.S. Army had expressed in this area of technology and the beginnings of what would become a cooperative program in aeronautical research with Ames. Thus, powered-lift research grew into a major effort that has lasted to the present day, supporting military along with newly emerging civil needs. It included the development and flight of several proof-of-concept aircraft, particularly the XV-15 tilt rotor, which stands as one of Ames' most important contributions to aeronautical technology. Further, it was soon to be augmented with rotorcraft flight research when NASA chose to consolidate rotary-wing technology efforts at Ames in the late 1970s. This research was supported and strongly influenced by the Army through its research laboratory, which had been established and collocated at Ames in the late 1960s. This collaborative program continues to this day.

Download or read book Rotorcraft Aeromechanics written by Wayne Johnson and published by Cambridge University Press. This book was released on 2013-04-29 with total page 949 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rotorcraft is a class of aircraft that uses large-diameter rotating wings to accomplish efficient vertical take-off and landing. The class encompasses helicopters of numerous configurations (single main rotor and tail rotor, tandem rotors, coaxial rotors), tilting proprotor aircraft, compound helicopters, and many other innovative configuration concepts. Aeromechanics covers much of what the rotorcraft engineer needs: performance, loads, vibration, stability, flight dynamics, and noise. These topics include many of the key performance attributes and the often-encountered problems in rotorcraft designs. This comprehensive book presents, in depth, what engineers need to know about modelling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behaviour. The first third of the book is an introduction to rotorcraft aerodynamics, blade motion, and performance. The remainder of the book covers advanced topics in rotary wing aerodynamics and dynamics.

This book was released on 2018-07-17 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pioneer Aerospace Corporation (PAC) conducted parafoil wind tunnel testing in the NASA-Ames 80 by 120 test sections of the National Full-Scale Aerodynamic Complex, Moffett Field, CA. The investigation was conducted to determine the aerodynamic characteristics of two scale ram air wings in support of air drop testing and full scale development of Advanced Recovery Systems for the Next Generation Space Transportation System. Two models were tested during this investigation. Both the primary test article, a 1/9 geometric scale model with wing area of 1200 square feet and secondary test article, a 1/36 geometric scale model with wing area of 300 square feet, had an aspect ratio of 3. The test results show that both models were statically stable about a model reference point at angles of attack from 2 to 10 degrees. The maximum lift-drag ratio varied between 2.9 and 2.4 for increasing wing loading. Geiger, R. H. and Wailes, W. K.

Available in PDF, EPUB and Kindle. Book excerpt: The Integrated Test Facility (ITF), being built at the NASA Ames Research Center's Dryden Flight Research Facility (ADFRF), will provide new real-time test capabilities for emerging research aircraft. An overview of the ITF and the real-time systems being developed to operate this unique facility are outlined in this paper. The ITF will reduce flight-test risk by minimizing the difference between the flight- and ground-test environments. The ground-test environment is provided by combining real-time flight simulation with the actual aircraft. The generic capabilities of the ITF real-time systems, the real-time data recording, and the remotely augmented vehicle (RAV) monitoring system will be discussed. The benefits of applying simulation to aircraft-in-the-loop testing and RAV monitoring system capabilities to the X-29A flight research program will also be discussed.

This book was released on 1985 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA-ARC has an ongoing research program to investigate high-angle-of-attack aerodynamic phenomena associated with high-performance aircraft. As part of this research, two rotary-balance apparatuses have recently been developed for testing airplane models in a coning motion. A new large-scale apparatus, developed for use in the 12-Foot Pressure Wind Tunnel primarily to permit testing at high Reynolds numbers, was recently used to investigate the aerodynamics of a 0.05-scale model of the F-15 fighter aircraft. Effects of Reynolds number, spin-rate parameter, model attitude, presence of a nose boom, and model/sting mounting angle were investigated. A smaller apparatus has been used in the 6- by 6-foot supersonic wind tunnel to investigate the aerodynamic behavior of a simple representation of a modern fighter, the Standard Dynamics Model (SDM). Effects of spin-rate parameter and model attitude were investigated. This paper presents a description of the two rigs and a discussion of some of the results obtained in the respective tests.
