Improved resistance to engine bird ingestion by Herbert B Kaehler( Book )

5 editions published in 1977 in English and held by 88 WorldCat member libraries worldwide

An analytical design method capable of quantitatively evaluating and ranking rotor blades for resistance to bird impact damage was investigated. This method was used to design blades having sufficient tolerance to meet the bird-ingestion requirements of FAR 33.77 for turbofan engines in the 6800 to 1600 lbf thrust class. The design procedure was also used for the preliminary design of a damage resistance boron/aluminum composite fan blade for the 6800 lbf thrust class engine. In addition, two protective devices designed to prevent an ingested bird from striking sensitive engine parts were presented. (Author)

Recycling of asphalt concrete airfield pavement : a laboratory study by R. B Brownie( Book )

4 editions published in 1979 in English and held by 87 WorldCat member libraries worldwide

Laboratory experiments have been conducted on aged asphalt concrete (AC) pavement samples obtained from three Naval airfields and two civil airports to develop and establish criteria and design guidelines for recycling such pavements. In these experiments, tests were conducted on nine agents for softening residual asphalt cements and designed hot- and cold-mix samples. It was found that aged AC pavement materials can be recycled to meet FAA and Navy specifications for new pavement surfaces and base courses by hot-mix recycling procedures and new base courses by cold-mix recycling procedures. Based on the results of this investigation, criteria and design guidelines for recycling aged AC pavements by hot-mix and cold-mix procedures have been established. (Author)

Turbine engine particulate emission characterization by D. L Fenton( Book )

4 editions published in 1977 in English and held by 85 WorldCat member libraries worldwide

A particulate sampling system has been designed and fabricated for the collection of exhaust particles emitted by aircraft turbine engines. The samples obtained by the sampling system were suitable for the determination of total mass emission rate and characterization of the exhaust particles. Two separate samples were necessary - a bulk sample for mass emission rate and a light deposit of particles for individual characterization. Operational adjustments and performance evaluations were made utilizing a TF-30 MIXED-FLOW TURBOJET ENGINE. The reliability of the data was established through repeated tests and the collaboration among the different techniques used to characterize the particles. (Author)

Assessment of the capacity of the automated radar terminal systems (ARTS IIIA) for the years 1980-1990 by William Pailen( Book )

4 editions published in 1980 in English and held by 81 WorldCat member libraries worldwide

The capability of the ARTS IIIA to support future air traffic growth and functional enhancements through 1990 is examined. The approach used is to investigate a few high traffic density sites which are representative of the three current terminal system configurations: single sensor sites (Detroit); dual sensor sites (Chicago, Los Angeles); and Metroplexes (New York). Loading factors are determined for each model site. These factors include the number and type of sensors and displays, the instantaneous traffic counts, and functional capability. The loading parameters are then used as inputs to a processing model, developed in this study, in order to determine if the ARTS IIIA can provide adequate processing capacity. The loading parameters are also used to develop estimates of memory requirements. The results of the study indicate that processing capacity limitations, if not overcome, will likely constrain functional growth at Metroplex facilities but will present no problems for single and dual sensor sites. Current memory capacity limitations are shown to present significant problems for both Metroplexes and dual sensors sites

High velocity jet noise source location and reduction : Task 4, Development/evaluation of techniques for "inflight" investigation( Book )

7 editions published in 1977 in English and held by 79 WorldCat member libraries worldwide

This report presents the results of Task 4 as conducted under the subject program over a period of 30 months. Task 4 was formulated to identify and evaluate several inflight simulation techniques, select the most promising technique for demonstration and validation, and employ that technique in testing under Task 5 of the program. Techniques evaluated include closed-circuit wind tunnels, free jets, rocket sleds, and high speed trains. Pertinent results from the evaluation phase and rationale which led to selection of the free jet simulation technique are discussed, including advantages and disadvantages. The results of a theoretical study aimed at relating the noise signature obtained in a free jet facility for simulation of forward flight effects on jet noise with the noise signature in true flight are presented. Transformation is carried out by extracting 'static directivity' of the noise after correcting for refraction, turbulent scattering, and absorption effects, and then employing a suitable multipole source decomposition to evaluate the proper dynamic effect. A flowchart describing the details of the transformation procedure and a listing of the computer program are included. Acoustic results from the Learjet and NASA-Lewis F-106 Aircraft Flyovers and the French Aerotrain Tests, taken with a baseline, 8-lobe, and 104-tube nozzle were used to formulate a data base for verification of the free jet simulation technique. Detailed directivity and spectra comparisons between aerotrain data and transformed free jet data are presented for three primary jet velocities and two flight velocities for the three nozzle types
Commercial airport operations and community noise criteria by J. E Mabry( Book )

5 editions published in 1978 in English and held by 79 WorldCat member libraries worldwide

This study program involved response of 48 persons to seven different simulated commercial airport noise environments. Each exposure period was of 1-1/2 hours duration and subjects experienced and rated eight of these 1-1/2 hour noise exposure periods. The test environments simulated a conventional living room environment. Number of aircraft noise intrusions per exposure period ranged from 6 to 18 flyovers and indoor Leq(dBA) levels ranged from 38.9 to 52.1 dB. Some of the conclusions are: Noise exposure from a 'new' aircraft fleet mix (circa 1980) is clearly more acceptable than that from an 'old' fleet mix (circa 1965). Commonly used noise exposure methods such as NEF, Leq, and mean peak dBA are level dependent. Depending on the noise exposure method used, 2.5 to 4.0 dB is perceived as a reliable change in noise exposure. Predictive capability of a noise exposure method is a function of the engineering calculation procedure employed to weight the acoustic energy. Mean peak level exposure methods have greater predictive capability than energy summation methods. Leq(dBA) is a relatively poor predictor. (Author)
Assessment of the performance of an active ATCRBS mode for beacon collision avoidance by Ned A Spencer( Book )

4 editions published in 1977 in English and held by 78 WorldCat member libraries worldwide

The active ATCRBS Mode of BCAS was tested in a NAFEC airborne test bed. After conducting many flights for purposes of the system shakedown, design refinement, and the setting of parameters, a series of detailed data collection flights was run. The report presents first, the results of approximately 100 one-on-one aircraft encounters in which the ability of BCAS to give a proper maneuver command was examined; second, the results of one and one-quarter hours of data on targets-of-opportunity in the environment of the Washington, D.C. TCA; and third, an examination of flights with a controlled target aircraft in the airspace near NAFEC to explore the effects of antenna coverage. A comparison is made between the results obtained in Washington, those from NAFEC flights, and those from simulated scenarios fed into the operating processor. (Author)
