Book General Aviation Interior Noise Part 2 In Flight Source Verification

Download or read book General Aviation Interior Noise Part 2 In Flight Source Verification written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-05-31 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technical approach made use of the Cessna Model 182E aircraft used in the previous effort as a test bed for noise control application. The present phase of the project reports on flight test results during application of various passive noise treatments in an attempt to verify the noise sources and paths for the aircraft. The data presented establishes the level of interior noise control that can be expected for various passive noise control applications within the aircraft cabin. Subsequent testing will address specific testing to demonstrate the technology available to meet a specified level of noise control by application of passive and/or active noise control technology.Unruh, James F. and Till, Paul D. and Palumbo, Daniel L.

Book Monitoring Aircraft Noise and Operations in the Vicinity of Airports System Validation

Download or read book Monitoring Aircraft Noise and Operations in the Vicinity of Airports System Validation written by A-21 Aircraft Noise Measurement Aviation Emission Modeling and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Recommended Practice (ARP) provides engineering methods that can be applied to monitoring aircraft noise and operations in the vicinity of airports using either attended or unattended monitoring systems, as well as methods for validation of measurement results from permanent systems. Part 1 provides guidance on the components, installation and administration of permanent systems and guidance on analysis of data collected from temporary monitoring of aircraft noise. Part 2, this part, describes both system screening tests and detailed test methods for validating the data reported by permanently installed systems. This document is intended as a guide toward standard practice and is subject to change with experience and technical advances.Potential users include: airport proprietors, airport neighbors, federal, state and local government agencies, equipment vendors and other public bodies and officials. Potential applications include: Part 1 - development of a basis for communication among concerned parties for acquisition, installation and operation of a permanent monitoring system, and reduction of sound level data collected through temporary monitoring; Part 2 - initial system testing and detailed system validation and improvement.The recommended practices included here are intended to apply to commercial air carrier airports and general-aviation airports.The guidance in Part 1 of this document is intended for application to airport noise-monitoring systems that are designed and installed (or refurbished) after the publication date of the document. Part 1 also provides methods for analyzing data from temporary noise monitoring. The methods and information in Part 2 may be used for any permanent monitoring system.The primary topics addressed in this Part 2 are identified in six subsections. Sections 2 and 3 give References and Definitions. Section 4, Post-Installation Screening Tests, identifies tests that may be conducted immediately after a system has been installed and is operational. These tests use only data directly from the system and should efficiently identify any major short-comings, such as missing significant numbers of operations, missing or erroneous aircraft noise event data. These tests may also be run at any time that some major portion or type of system reported data is in question.Section 5, System Validation for Special Studies, provides more rigorous and time consuming methods for quantifying a permanent system's capabilities when special needs require detailed, quantitative analysis of system data. It describes metrics, tests and calculations that can be used to determine how well the system is: (1) capturing all aircraft flight tracking information, (2) matching captured tracks to runways, aircraft types and flights, (3) capturing aircraft noise events, (4) matching those events with correct tracks, runways and aircraft, (5) measuring aircraft sound levels, and (6) properly locating aircraft flight tracks.Section 6 - Data Analysis and Reporting - Suggests what general steps can be taken to improve system operation and how measured data should be reported to provide sufficient information so that reviewers can easily judge data quality.Appendices provide related and additional information. ARP4721 Part 2 has been reaffirmed to comply with the SAE five-year review policy.
