Noise measurement flight test of five light helicopters ( Book )
2 editions published in 1993 in English and held by 86 libraries worldwide
The U.S. Department of Transportation, Federal Aviation Administration, (U.S. DOT/FAA), along with the U.S. DOT, Research and Special Programs Administration, Volpe National Transportation Systems Center (RSPA/ volpe Center) conducted a helicopter noise measurement flight test in Champaign, Illinois, during the period July 22 through 26, 1991. The primary objective of the study was to obtain the field data necessary to examine the feasibility of a Bimplified helicopter-noise-certification procedure (screening test). Acoustic data were measured by and stored on a hand-held sound-level meter (on-line processing) and recorded on digital tape for later off-line processing. A comparison of the measured on-line acoustic data with the acoustic data processed off-line provided the foundation necessary to evaluate the feasibility of the proposed screening test. In addition to acoustic measurements, meteorological data and helicopter tracking and performance data were also obtained ... Helicopter, Noise Measurement, Acoustic, Configuration, Meteorological

On the interpretation of infrared solar spectra for altitude distribution of atomospheric trace constituents by United States( Book )
3 editions published in 1978 in English and held by 76 libraries worldwide
The quantitative interpretation of infrared sunset spectra in terms of mixing ratio profiles of atmospheric constituents requires a detailed consideration of the airmass and pressure distribution along the sunset ray. A comptuer program has been developed for determining the airmass and pressure distribution along this ray. Since infrared absorptions are pressure-dependent, a technique has been developed for treating this pressure dependence in analyzing absorption over such paths. The technique uses an approximation which maintains computational accuracy for such paths while reducing the computer time required for the calculations. The interpretation of such spectra is further complicated if the concentration of the constituent of interest varies with solar zenith angle (e.g. NO). Calculations were performed using time-varying profiles for NO and NO2. These calculations show that, if this time variability is not taken into account, the inferred profiles are greatly in error in the case of NO and marginally in error for NO2

High altitude pollution program stratospheric measurement system laboratory performance capability report chemical conversion techniques ( Book )
2 editions published in 1980 in English and held by 75 libraries worldwide
This report documents the laboratory measurements made to resolve specificity questions concerning the chemical conversion techniques for measurement of stratospheric trace species NO2, N2O5, and HNO3 to NO (Which is the measurable species). Particular emphasis was placed on the conversion of NO2 to NO by both catalytic and photolytic converters, thermal conversion of N2O5 and HNO3 to N02 with and without possible interfering gases, and the feasibility of measuring total odd-nitrogen concentration using catalytic thermal conversion to NO. The laboratory measurements were generally carried out at ppm concentrations at STP conditions. The GEARS/EPISODE computer code was used to model both the laboratory reactions and the behavior of the technique at stratospheric conditions. The laboratory measurement and stratospheric simulations lead to the recommendation to develop a flight prototype of a Hybrid Gas Conversion System consisting of a number of instrumentation modules. The first module would be a Total Odd-Nitrogen module (and NO) based on high temperature catalytic conversion of the odd-nitrogens and chemiluminescent detection of NO. The second module would be an NO2/NO module based on NO2 photolysis and NO chemiluminescent detection. Other modules could consist of an O3 UV photometer, and N2O gas chromatograph, and other appropriate modules that are ready at flight time. (Author)

Parameters for ozone photolysis as a function of temperature at 280-330 NM by John E Davenport( Book )
6 editions published between 1980 and 1982 in English and held by 74 libraries worldwide
This study was undertaken to obtain the parameters for ozone photolysis in the 280-330 nm region as a function of temperature in the 200-300 K range. The absolute absorption coefficients for 03 were measured at 298, 271, 225, and 206 K and were tabulated at 1-nm intervals over the 250-370 nm wavelength range. Uncertainties in the absorption coefficients range from 2% at room temperature to about 14% at 206 K and mainly fall in the 3-7% range. Pressure of 0.02-100 torr ozone were used, and no pressure effect was observed up to 800 torr N2

Assessment of the environmental compatibility of differing helicopter noise certification standards ( Book )
3 editions published in 1979 in English and held by 71 libraries worldwide
Areas having the heaviest helicopter activity in the U.S. were visited and environmental noise measurement made in order to evaluate the impact of possible relaxed noise emission standards for helicopters restricted to remote regions. Measurement results showed that an average of 10 flyovers per hour produced a one-hour energy-averaged sound level (Leq) of 54.5 dBA, a level 2.5 dBA above ambient. An average of 34 events per hour adjacent to heliports produced a one-hour Leq of 63.1 dBA, which was 13.3 dBa above ambient. If emission levels were increased by 10 dBA, projected Leq values of 57.0 and 71.2 dBA resulted for the flyover and heliport conditions, respectively. Sixty-four percent of those responding to a questionnaire stated that they had not experienced a problem from helicopter noise. The degree to which the remaining respondents were bothered ranged from 'slightly' to 'very annoyed' with no significant preference for either category. (Author)

Noise levels and data correction analysis for seven general aviation propeller aircraft by United States( Book )
2 editions published in 1980 in English and held by 70 libraries worldwide
This document reports noise levels of a general aviation propeller aircraft noise test at the FAA National Aviation Facility Experimental Center located in Atlantic City, New Jersey. The test was performed to acquire noise data on general aviation type aircraft and examine how these noise levels are influenced by variables such as distance, aircraft speed, power settings, and propeller speeds. Aircraft were tested during takeoff, approach, and flyover modes and data are given in EPNL and in 'A'-weighted decibels. All measurements were performed in accordance with FAR 36 Appendix C and Appendix F procedures. (Author)
On the applicability of two- and one-dimensional parameterizations of atmospheric tracer transports to prognostic photochemical models of the stratosphere by Henry Hidalgo( Book )
2 editions published in 1980 in English and held by 70 libraries worldwide
This paper deals with the applicability of empirical parameterizations of stratospheric transports of chemically inert tracers to predictive or prognostic two- and one-dimensional photochemical models of the stratosphere and troposphere for the forecasting of anthropogenic effects on atmospheric ozone. The scope of this paper therefore includes: (1) a critical review and assessment of the prognostic utility of the parent Reed and German (1965) 2-D parameterization of stratospheric transports; (2) the implied assumption in representative subsidiary 2D parameterizations used or for use in 2-D photochemical models; (3) use of GCM/tracer model data for a chemically inert tracer for the assessment of the prognostic utility of both 2-D and 1-D parameterizations of stratospheric transports; and (4) the outlook for the development of prognostic parameterizations of stratospheric transports.

Recent developments in the estimation of potential effects of high altitude aircraft emissions on ozone and climate by R. C Oliver( Book )
2 editions published in 1979 in English and held by 69 libraries worldwide
A review is provided of recent (December 1976-June 1978) developments in problems associated with estimating the potential effects that aircraft emissions at cruise altitudes may have on the earth's protective ozone shield and/or surface climate. Background information is provided as deemed necessary for context. The review shows that one recently measured key reaction rate(HO2 + NO yields NO2 + HO) has had dramatic effects on the ozone question. Computed effects on the ozone column of nitrogen oxides (which, unless in very large quantity, now cause an increase) and water vapor emissions (which, unless thermal feedback effects are included, cause a decrease) from supersonic transports (at 17-20 km) are now small and, on balance, apparently positive, at least for moderate fleets (several hundred aircraft). Subsonic aircraft also appear to cause small increases in the ozone column; however, on new modeling results are available. The new HO2 + NO rate has affected model duplication of the natural atmosphere adversely; another important new rate (HO2 + O3 yields HO + 2 O2), not yet incorporated in available results, may reduce this difficulty. Second-order effects (thermal feedback) have become important, particularly in modeling water effects; the modeling of water transport processes, however, involves many uncertainties. Additional modeling studies are needed. Progress in emissions measurement uncertainties and brief comments on possibly important climatic aspects are also included. (Author)

Two-dimensional description of potential perturbations to the ozone layer due to NOx and H₂O aircraft emissions by George F Widhopf( Book )
3 editions published in 1984 in English and held by 69 libraries worldwide
This report is divided into two parts. Part I is an interim report, which describes the basic two-dimensional photochemical model of the atmosphere developed to model the distribution of trace species in the natural atmosphere, as well as potential perturbations arising from NOx and H2O emissions from a fleet of supersonic and subsonic aircraft projected to be operational in the 1990-2000 year timeframe. A listing of the model transport parameters is included. Part II includes an update for the natural and perturbed atmosphere using rates recommended by the panel in 1982. Distributions of trace species calculated for a natural atmosphere are in relatively good agreement with observations. The potential effect of NO emissions from the fleet of subsonic and supersonic aircraft examined in this study is to slightly increase the ozone column
Status of representative two-dimensional models of the stratosphere and troposphere as of mid-1978 by Henry Hidalgo( Book )
3 editions published in 1978 in English and held by 68 libraries worldwide
This paper reviews ongoing efforts aimed at solution of basic problems dealing with ozone chemistry and atmospheric mass transports in representative two-dimensional (altitude and latitude) photochemical models of the troposphere and stratosphere. Emphasis is placed on the impact of recent measurements of the reaction rate coefficients for HO2 + NO yields OH + NO2 and HO2 + 03 yields OH + 2 02 on: (a) the balance between ozone production and destruction on both ozone concentrations and columns at middle northern latitudes during summer for an oxygen-hydrogen-nitrogen atmosphere; (b) calculation of NO sub x concentrations in the upper troposphere which are important for the effects of high-altitude subsonic flight on the ozone column; and (c) estimates of the tropospheric NO sub x and OH concentrations as well as the removal rates of water-soluble species in the lower troposphere from considerations of the tropospheric ozone and carbon monoxide budgets. The severe limitations of arbitrary extensions of available 2-D parameterizations of the dynamics to an upper troposphere and lower stratosphere assumed to be perturbed by large emissions of engine effluents are brought out from numerical solutions of the primitive equations for instantaneous and continuous sources of inert material in the lower stratosphere. The paper includes preliminary 2-D results based on the revised ozone chemistry for the trend of subsonic and supersonic flight effects ozone
