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.

Flights of the F-1513/Propulsion Flight Test Fixture (PFTF) with a Cone Drag Experiment (CDE) attached have been accomplished at NASA Dryden Flight Research Center. Mounted underneath the fuselage of an F-15B airplane, the PFTF provides volume for experiment systems and attachment points for propulsion experiments. A unique feature of the PFTF is the incorporation of a six-degree-of-freedom force balance. The force balance mounts between the PFTF and experiment and measures three forces and moments. The CDE has been attached to the force balance for envelope expansion flights. This experiment spatially and inertially simulates a large propulsion test article. This report briefly describes the F-15B airplane, the PFTF, and the force balance. A detailed description of the CDE is provided.

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.

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
