Book Synopsis The Use of Composite Omega and the 3.4 KHz Difference Frequency for Aircraft Navigation by : John W. Brogden
Download or read book The Use of Composite Omega and the 3.4 KHz Difference Frequency for Aircraft Navigation written by John W. Brogden and published by . This book was released on 1972 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Aviation Administration (FAA) furnished the National Hurricane Research Laboratory with an Omega aircraft receiving system which was manufactured by Tracor, Inc. This system was installed in a hurricane watch aircraft operating out of Miami, Flordia. FAA was interested in obtaining data on the usefulness of Composite Omega and the uncorrected difference frequency (3.4 kHz) for aircraft navigation. The Naval Research Laboratory (NRL) was requested by FAA to recommend procedures for obtaining data and methods for data reduction. Data was to be collected on routine flights and reduced by the National Hurricane Research Laboratory and then sent to NRL for analysis. Results that were submitted show extremely large errors in position that could only have been caused by receiver malfunctions or in the data reduction. Therefore no significant conclusions could be drawn from the information that was submitted. Since the main purpose of the study was not achievable it was felt that fixed site data could also be used to evaluate the composite Omega concept. However, whithin the funds available only a limited amount of fixed data could be analyzed and therefore the results are not conclusive. The limited data show no significant improvement in the errors due to diurnal variations of composite Omega over the 3.4 kHz difference frequency. The data did show however that the fluctuations due to noise were reduced by the composite Omega method over what was shown by the 3.4 kHz difference frequency data. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Naval Research Laboratory (NRL) conducted an investigation to determine the effect of multi-mode propagation on the usefulness of the Omega 3.4 KHz difference frequency for aircraft navigation. This investigation was conducted under the sponsorship of the Federal Aviation Administration (FAA) and with the cooperation of the National Oceanic and Atmospheric Administration (NOAA). A NOAA aircraft that was equipped with Omega receivers was used for this investigation. Flights were made between Grand Forks AFB, Grand Forks, North Dakota and Piarco airport in Trinidad. Position fixes, for comparison with those obtained from the Omega system, were obtained from the standard VOR/VORTAC stations when the aircraft was over the continental United States and doppler radar and inertial systems were used on the portion of the flights that were over water. The flights made during nighttime conditions when the effects of multi-mode propagation were the most pronounced. The data for this specific path and under nighttime conditions show that the 3.4 kHz difference frequency can be used for navigation using only simple correction factors if an accuracy of + or - 5 miles is acceptable. More data are required to determine the accuracy that can be obtained in other areas and during other propagation conditions. (Author).
Book Synopsis Composite Omega: Omega Navigation Using a Combination of Information from Radiations at 10.2 and 13.6 KHz by :
Download or read book Composite Omega: Omega Navigation Using a Combination of Information from Radiations at 10.2 and 13.6 KHz written by and published by . This book was released on 1969 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of composite Omega, as developed by J.A. Pierce, is shown to be equivalent to a statistical optimization of the information available from two Omega carrier frequencies. However, composite Omega offers no increased stability over that available from the 13.6-kHz carrier except over arctic paths during disturbed conditions. From a statistical standpoint, conventional lane resolution of the 10.2-kHz carrier lanes from 3.4-kHz difference frequency measurements is a virtual certainty except during disturbed conditions.

Book Synopsis Structural Health Monitoring Damage Detection Systems for Aerospace by : Markus G. R. Sause
Download or read book Structural Health Monitoring Damage Detection Systems for Aerospace written by Markus G. R. Sause and published by Springer Nature. This book was released on 2021 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.
