The NASA F-15 Intelligent Flight Control System project team has developed a series of flight control concepts designed to demonstrate the benefits of a neural network-based adaptive controller. The objective of the team is to develop and flight-test control systems that use neural network technology to optimize the performance of the aircraft under nominal conditions as well as stabilize the a...

The Mosquito is Glasflügel's entry into the 15-meter flapped sailplane racing category, and it is a sleek, modern, fiberglass sailplane that is both meticulously engineered and pleasing to the eye. Its well-known cousins are the AS-W 20, LS-3, and Mini-Nimbus. All four made their competition debuts during the 1977 summer season. Our Dallas Gliding Association testing has already been completed ...

This paper provides a comprehensive description of an acoustic flight test of the XV15 Tiltrotor Aircraft with Advanced Technology Blades (ATB) conducted in August and September 1991 at Crows Landing, California. The purpose of this cooperative research effort of the NASA Langley and Ames Research Centers was to obtain a preliminary, high quality database of far-field acoustics for terminal are...

Flight testing of aircraft in which new design concepts, problems, and deficiencies are examined, involves the collection of a large quantity of data or test parameters allocated onto blocks within a telemetry frame or Data Cycle Map (DCM). Individual parameters are sampled at different rates and may vary in both their word length and the number of words used to represent them. During a flight ...

The algorithms onboard Unmanned Aerial Vehicles are increasing in complexity and thus require a well established concept to flight test development process to accelerate deployment and avoid loss of aircraft. We present a modular multi-UAV algorithm development framework which combines design, simulation, performance evaluation and deployment in a single, high level graphical environment. The f...

NASA’s Morpheus Project has developed and tested a prototype planetary lander capable of vertical takeoff and landing, that is designed to serve as a testbed for advanced spacecraft technologies. The lander vehicle, propelled by a Liquid Oxygen/Methane engine and sized to carry a 500 kg payload to the lunar surface, provides a platform for bringing technologies from the laboratory into an integ...

‘‘Dear Colleague, Please see and advise on this patient with COPD who wishes to fly’’. This is a common request from our non-respiratory colleagues and although we have guidelines to follow to assist in answering their queries, the evidence on which the guidelines are based is weak. The most recently published air travel recommendations are those from the British Thoracic Society (BTS) [1], whi...

We describe the BOOMERanG experiment, a stratospheric balloon telescope intended to measure the Cosmic Microwave Background anisotropy at angular scales between a few degrees and ten arcminutes. The experiment has been optimized for a long duration (7 to 14 days) flight circumnavigating Antarctica at the end of 1998. A test flight was performed on Aug.30, 1997 in Texas. The level of performance...

time-of-flight diffraction method (tofd) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. although tofd can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. in this paper, a new tofd method for evaluating horizontal planar defects is presented. the finite...
