This book was released on 2018-07-08 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA Dryden Flight Research Center has developed a second-generation flight test fixture for use as a generic test bed for aerodynamic and fluid mechanics research. The Flight Test Fixture 2 (FTF-2) is a low-aspect-ratio vertical fin-like shape that is mounted on the centerline of the F-I5B lower fuselage. The fixture is designed for flight research at Mach numbers to a maximum of 2.0. The FTF-2 is a composite structure with a modular configuration and removable components for functional flexibility. This report documents the flow environment of the fixture, such as surface pressure distributions and boundary-layer profiles, throughout a matrix of conditions within the F-15B/FTF-2 flight envelope. Environmental conditions within the fixture are presented to assist in the design and testing of future avionics and instrumentation. The intent of this document is to serve as a user's guide and assist in the development of future flight experiments that use the FTF-2 as a test bed. Additional information enclosed in the appendices has been included to assist with more detailed analyses, if required. Richwine, David M. Armstrong Flight Research Center...

Book excerpt: The design and development of the F-15B Propulsion Flight Flight Test Fixture (PFTF), a new facility for propulsion flight research, is described. Mounted underneath an F-15B fuselage, the PFTF provides volume for experiment systems and attachment points for propulsion devices. A unique feature of the PFTF is the incorporation of a six-degree-of-freedom force balance. Three-axis forces and moments can be measured in flight for experiments mounted to the force balance. The NASA F-15B airplane is described, including its performance and capabilities as a research test bed aircraft. The detailed description of the PFTF includes the geometry, internal layour and volume, force-balance operations, available instrumentation, and allowable experiment size and weight. The aerodynamic, stability and control, and structural designs of the PFTF are discussed, included results from aerodynmaic computational fluid dynamic calculations and structural analyses.

Available in PDF, EPUB and Kindle. Book excerpt: Flight vibration data are analyzed for the NASA F- 1 5B/Flight Test Fixture 11 test bed. Understanding the in-flight vibration environment benefits design and integration of experiments on the test bed. The power spectral density (PSD) of accelerometer flight data is analyzed to quantify the in-flight vibration environment from a frequency of 15 Hz to 1325 Hz. These accelerometer data are analyzed for typical flight conditions and maneuvers. The vibration data are compared to flight-qualification random vibration test standards. The PSD levels in the lateral axis generally are greater than in the longitudinal and vertical axes and decrease with increasing frequency. At frequencies less than approximately 40 Hz, the highest PSD levels occur during takeoff and landing.

Available in PDF, EPUB and Kindle. Book excerpt: A new boundary-layer rake has been designed and built for flight testing on the NASA Dryden Flight Research Center F-15B/Flight Test Fixture. A feature unique to this rake is its curved body, which allows pitot tubes to be more densely clustered in the near-wall region than conventional rakes allow. This curved rake design has a complex three-dimensional shape that requires innovative solid-modeling and machining techniques. Finite-element stress analysis of the new design shows high factors of safety. The rake has passed a ground test in which random vibration measuring 12 g rms was applied for 20 min in each of the three normal directions. Aerodynamic evaluation of the rake has been conducted in the NASA Glenn Research Center 8x6 Supersonic Wind Tunnel at Mach 0-2. The pitiot pressures from the new rake agree with conventional rake data over the range of Mach numbers tested. The boundary-layer profiles computed from the rake data have been shown to have the standard logarithmic-law profile. Skin friction values computed from the rake data using the Clauser plot method agree with the Preston tube results and the van Driest II compressible skin friction correlation to approximately plus/minus 5 percent.

The PSD levels in the lateral axis generally are greater than in the longitudinal and vertical axes and decrease with increasing frequency. At frequencies less than approximately 40 Hz, the highest PSD levels occur during takeoff and landing. Peaks in the PSD data for the test fixture occur at approximately 65, 85, 105-110, 200, 500, and 1000 Hz. The pitch-pulse and 2-g turn maneuvers produce PSD peaks at 115 Hz. For cruise conditions, the PSD level of the 85-Hz peak is greatest for transonic flight at Mach 0.9. From 400 Hz to 1325 Hz, the takeoff phase has the highest random vibration levels. The flight-measured vibration levels generally are substantially lower than the random vibration test curve.Corda, Stephen and Franz, Russell J. and Blanton, James N. and Vachon, M.

Available in PDF, EPUB and Kindle. Book excerpt: According to Aulus Gellius, Archytas, the Ancient Greek philosopher, mathematician, astronomer, statesman, and strategist, was reputed to have designed and built, around 400 BC, the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have actually flown some 200 metres. This machine, which its inventor called The Pigeon, may have been suspended on a wire or pivot for its flight. The 9th century Muslim Berber inventor, Abbas Ibn Firnas's glider is considered by John Harding to be the first attempt at heavier-than-air flight in aviation history. In 1010 AD an English monk, Eilmer of Malmesbury purportedly piloted a primitive gliding craft from the tower of Malmesbury Abbey. Eilmer was said to have flown over 200 yards (180 m) before landing, breaking both his legs. He later remarked that the only reason he did not fly further was because he forgot to give it a tail, and he was about to add one when his concerned Abbot forbade him any further experiments. Bartolomeu de Gusmão, Brazil and Portugal, an experimenter with early airship designs. In 1709 demonstrated a small airship model before the Portuguese court, but never succeeded with a full-scale model. Pilâtre de Rozier, Paris, France, first trip by a human in a free-flying balloon (the Montgolfière), built by Joseph-Michel and Jacques-Étienne Montgolfier, . 9 km covered in 25 minutes on October 15, 1783. (see Le Globe below for first unmanned flight, 2 months earlier) Professor Jacques Charles and Les Frères Robert, two French brothers, Anne-Jean and Nicolas-Louis, variously shared three milestones of pioneering flight: Le Globe, the first unmanned hydrogen gas balloon flew on 26 August 1783. On 1 December 1783 La Charlière piloted by Jacques Charles and Nicolas-Louis Robert made the first manned hydrogen balloon flight. In 1951, the Lockheed XFV-1 and the Convair XFY tailsitters were both designed around the Allison YT40 turboprop engine drivin
