Book Synopsis 1985 Small Propeller-Driven Aircraft Noise Test Program by : Kenneth E. Jones
Download or read book 1985 Small Propeller-Driven Aircraft Noise Test Program written by Kenneth E. Jones and published by . This book was released on 1985 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international aviation community is currently reviewing noise certification procedure for small propeller-driven aircraft. Under discussion is a proposal to substitute a ground-plane microphone for the currently specified elevated microphone as a means of suppressing spectral irregularities. Given the strong low and mid-range tonal frequencies attendent to propeller-driven aircraft, the constructive/destructive interference pattern in an aircraft frequency spectrum can result in inconsistent certification test results for aircraft with different blade passage frequencies. The Federal Aviation Administration conducted several flight tests during the summer of 1985 in-order-to compare noise levels measured at four feet to ground-plane levels as a function of the blade passage frequency. The purpose of this report is to present a preliminary assessment of the data acquired during the flight tests. A more comprehensive analysis of the test results will be documented in the final report. Three flight tests were performed using a Cessna 210, Cessna Caravan I, and a (Beechcraft) U.S. NAVY T-34C. A vertical array (3.75 to 7.0 ft.) of microphones and a range of test RPMs were used in-order-to test the theoretical prediction of the ground reinforcement effect. As a secondary objective, the microphones were redeployed in horizontal arrays to test for a difference in variability between elevated and ground-plane microphones. The primary installation for the ground-plane microphone was over a 0.4 meter circular metal plate. A comparison was also made between 0.4 meter and 36 inch diameter ground plates.

This book was released on 1985 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September, 1984, the FAA, with the cooperation and support of the General Aviation Manufacturers' Assoc. (GAMA), conducted a noise measurement program on small propeller-driven aircraft at Salina Municipal Airport, Salina, Kansas. The program objectives were: (1) to obtain takeoff noise data using prepared international and U.S. certification procedures for propeller-driven small airplanes; and (2) to measure the benefits of noise abatement takeoff procedures being developed by the manufacturers for inclusion in the Pilot's Operating Handbook. For the five twin and four single engine aircraft tested, the results show an average noise reduction of 4.4 decibels when using reduced power procedures after takeoff. Keywords: General aviation; Noise abatement; Operating procedures.

This book was released on 1982 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the effectiveness of current noise regulations in Appendix F of FAR Part 36, examines the potential effectiveness of future technology to achieve further noise reduction, and evaluates a number of new concepts for noise certification procedures for propeller-driven small aircraft. The latter were based, in part, on results of a flight test program carried out with Cessna Aircraft Company, to evaluate the utility of takeoff noise tests and the possible use of sound exposure level as a suitable metric for noise certification of the subject aircraft. The study indicates that existing regulations have been effective in stimulating development of quieter propellers for the existing fleet of propeller-driven small aircraft. However, it does not appear economically feasible to achieve more noise reduction in most of this fleet using existing technology with the possible exceptions of some of the two-engine aircraft. However, application of future noise reduction technology, primarily for quieter propellers, should allow a reduction in current noise limits by about 6 dB and should reduce levels of the noisiest aircraft in the current fleet by as much as 10 dB. A takeoff test is appropriate for all propeller aircraft except those equipped with cruise-optimized fixed-pitch propellers. For this test, the current level flyover test appears to represent the noisiest operating condition.
Book Synopsis Noise Levels and Data Analyses for Small Prop-Driven Aircraft by : J. Steven Newman

Available in PDF, EPUB and Kindle. Book excerpt: During the Summer and Fall of 1982, the FAA Office of Environment and Energy, Noise Abatement Division, conducted a noise measurement program to evaluate proposed revisions of International and U.S. noise certification standards for light-weight propeller-driven aircraft. Tests were conducted using both single- and twin-engine propeller-driven light aircraft. Normally aspirated, turbo-charged, and turboprop engines were included, as were both fixed and variable pitch propellers. Takeoff noise measurements were made for eighteen aircraft. Additional measurements for nine of these aircraft (during level flight) provided sufficient data to examine the relationship of noise level versus helical tip Mach Number and engine power setting. This report presents noise measurements, aircraft position data, meteorological data, and cockpit instrument readings acquired during the test. Data analyses include: corrections to proposed noise certification reference conditions, development of Mach Number and Power Correction functions, empirical examination of sound propagation, regression of noise level versus weight (and the logarithm of weight) and correlation of acoustical intensity (AL) and acoustical dose (SEL) noise metrics. While this report concludes that a takeoff noise certification procedure is feasible and will provide consistent results for a given aircraft, it remains uncertain whether or not equal stringency (or even comparable stringency) can be achieved between the existing certification procedure and the proposed takeoff procedure.
