Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is twofold. First, the unique characteristics of a wide variety of helicopter operations which ended in a collision with terrain features or man-made obstructions were analyzed. Special emphasis was given to operations during difficult visual conditions. Second, this report provides the reader with systematic insights into the affiliated technical and operational aspects of helicopter flight operations which contributed to this category of accident. The report explores the way helicopters are flown in the low airspace and employs composite accident summaries as points of departure to both illustrate and substantiate the analysis which in turn identifies opportunities for improved flight safety and productivity in the National Airspace System (NAS). The included analysis deals with a series of rotorcraft accidents involving terrain and obstruction strikes. The common characteristics of these accidents support the need for specific changes. Each composite accident is illustrated and treated to an analysis which often allows the reader to focus on one characteristic in isolation. The summaries of these composite accidents and supporting analysis are included in the report to provide a common information base for the FAA analysts and industry engineers to support the need for additional equipment, new procedures, new products, additional training, and regulatory change. This technical report contains pertinent data and testing/guidance material needed to support those elements of the agency charged with performance of regulatory actions and the development of advisory materials and standards.

Available in PDF, EPUB and Kindle. Book excerpt: In a companion report entitled Analysis of Helicopter Mishaps at Heliports, Airports, and Unimproved Sites, DOT/FAA/RD-90/8, National Transportation Safety Board and U.S. Army mishap reports were reviewed in order to determine the types of mishaps that have occurred at helicopter landing sites. Based upon these mishap records, helicopter composite mishap profiles were developed and are presented here in order to demonstrate the types of mishaps that have occurred at or near heliports and airports. Each composite profile includes a description of the mishap, facility design factors which contributed to the mishap, nondesign-related contributing factors, and operational safety enhancements where appropriate. This document is intended to be a learning and teaching aid. The intended audience includes helicopter landing area designers, managers, and operators, as well as pilots. The goal of the report is to broaden awareness in the helicopter community in order to promote safety. This report is one in a series of three dealing with helicopter mishaps at landing sites. The other reports are: Analysis of Helicopter Mishaps at Heliports, Airports and Unimproved Sites, DOT/FAA/RD-90/8, and Analysis of Helicopter Accident Risk Exposure near Heliports, Airports, and Unimproved Sites, DOT/FAA/RD-90/9.

Download or read book Occupant Responses in a Full Scale Crash Test of the Sikorsky ACAP Helicopter written by and published by . This book was released on 2002 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A full-scale crash test of the Sikorsky Advanced Composite Airframe Program (ACAP) helicopter was performed in 1999 to generate experimental data for correlation with a crash simulation developed using an explicit nonlinear, transient dynamic finite element code. The airframe was the residual flight test hardware from the ACAP program. For the test, the aircraft was outfitted with two crew and two troop seats, and four anthropomorphic test dummies. While the results of the impact test and crash simulation have been documented fairly extensively in the literature, the focus of this paper is to present the detailed occupant response data obtained from the crash test and to correlate the results with injury prediction models. These injury models include the Dynamic Response Index (DRI), the Head Injury Criteria (HIC), the spinal load requirement defined in FAR Part 27.562(c), and a comparison of the duration and magnitude of the occupant vertical acceleration responses whole-body acceleration tolerance curve.

Download or read book Analysis of Helicopter Accident Risk Exposure Near Heliports Airports and Unimproved Sites written by and published by . This book was released on 1992 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the development of relevant safety indicators to be used in the assessment of risk exposure due to heliport design and operational standards. Since helicopter accidents have been relatively rare events, historical data at heliports are somewhat limited. Therefore, the approach described herein is to develop the total helicopter risk exposure due to all causes and then estimate what proportion of that risk should be allocated to various circumstances associated with specific heliport design and helicopter operational characteristics. This approach introduces the need for analysis and quantification of risk using a parameter or parameters that both industry and government agree are within a logical framework. Data on the number of helicopter accidents per year, accidents per 100,000 hours of flight time, accidents per 100,000 mission segments, accident rates for selected mission types, occupant risk of serious injury, and neighborhood risk are presented. Finally, civil helicopter accidents are categorized by the facilities near which they occur (heliport, airport, etc.) and by the operating facility design parameters that impact operational risk. This report is one of a series of three dealing with helicopter accidents near heliports, airports, and unimproved landing areas. The other reports are: 'Analysis of Helicopter Mishaps at Heliports, Airports, and Unimproved Sites' DOT/FAA/RD-90/8, 'Composite Profiles of Helicopter Mishaps at Heliports and Airports, ' DOT/FAAIRD-91/1.

This book was released on 1988 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the BK 117 helicopter a composite fuselage was designed, manufactured, and will be flight tested at MBB. Within the development programme evidence was given to the crashworthy design of the fuselage which was accomplished by a joint activity between MBB and DFVLR Stuttgart. The crash investigations were focused on the lower airframe section under vertical crash loads. The task was performed by design support tests on the specimen level and by sub-component crush testing. Sandwich panel specimens were statically and dynamically crushed to study various crush initiators at the panel-skin intersections, and to investigate the energy absorption capability. (JES).

This book was released on 2018-06-15 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: A full-scale crash test of a prototype composite helicopter was performed at the Impact Dynamics Research Facility at NASA Langley Research Center in 1999 to obtain data for validation of a finite element crash simulation. The helicopter was the flight test article built by Sikorsky Aircraft during the Advanced Composite Airframe Program (ACAP). The composite helicopter was designed to meet the stringent Military Standard (MIL-STD-1290A) crashworthiness criteria and was outfitted with two crew and two troop seats and four anthropomorphic dummies. The test was performed at 38-ft/s vertical and 32.5-ft/s horizontal velocity onto a rigid surface. An existing modal-vibration model of the Sikorsky ACAP helicopter was converted into a model suitable for crash simulation. A two-stage modeling approach was implemented and an external user-defined subroutine was developed to represent the complex landing gear response. The crash simulation was executed with a nonlinear, explicit transient dynamic finite element code. Predictions of structural deformation and failure, the sequence of events, and the dynamic response of the airframe structure were generated and the numerical results were correlated with the experimental data to validate the simulation. The test results, the model development, and the test-analysis correlation are described. Jackson, Karen E. and Fasanella, Edwin L. and Boitnott, Richard L. and Lyle, Karen H.
