Available in PDF, EPUB and Kindle. Book excerpt: Helicopters are being used in increasing numbers for military operations in countries throughout the world. In the U.S. Army, helicopters comprise approximately 94 percent of the active fleet. While medical considerations for helicopter operations are much the same as for fixed wing operations, there are some differences of emphasis that will be reviewed. A review of the past 5 year's accident experience reveals that 80 percent are attributed to human error. It is shown that crew error is never a sufficient explanation for an accident. The relationship of errors to system deficiencies is established through human factors analysis. Once identifide, appropriate measures can be instituted to correct these deficiencies. Since current operational helicopters are not equipped with systems for inflight escape, crashworthiness is a key issue in their design. Principles of helicopter crashworthiness are reviewed, and the means for deriving these principles from crash injury analysis is discussed.

Book excerpt: The extensive use of composite materials in helicopter structures has prompted new research activities in crashworthiness in the last decade. A rational design of crashworthy structures requires a great deal of data and experience to be collected and organized; in particular the most efficient mechanisms of energy adsorption must be understood and carefully investigated and consequently the best structural concepts an detail design can be identified. With this aim and in cooperation with Augusta Helicopters a research program has been undertaken, covering many of the basic aspects of crashworthy design, i.e. dynamic modeling, design and verification procedures.

Book excerpt: This paper discusses the evolution of crash survival design criteria, its influence on the formulation of a US Army military standard for rotary-wing aircraft crashworthiness, and its application to current and new-generation Army helicopters. Emphasis is given to the need for a total systems' approach in design for crashworthiness and the necessity for considering crashworthiness early in the design phase of a new aviation weapon systems development effort. The actual application of crashworthiness to Army helicopters is presented with statistics that show dramatic reductions in fatalities and injuries with implementation of a crashworthy fuel system. Current and planned US Army R & D to improve crashworthiness technology is discussed, including full-scale crash testing, human tolerance definition, improved energy absorbers, crew restraint systems, and crash impact characteristics of composite helicopter structures. Applicability of the work within Army helicopter crashworthiness to commercial/ civil helicopters is shown. The cost effective aspects of designing helicopters to be more crash survivable are also discussed.

Book excerpt: Results are presented from the U.S. Army-Aerostructures Directorate/NASA-Langley Research Center joint research program on helicopter crashworthiness. Through the on-going research program an in-depth understanding was developed on the cause/effect relationships between material and architectural variables and the energy-absorption capability of composite material and structure. Composite materials were found to be efficient energy absorbers. Graphite/epoxy subfloor structures were more efficient energy absorbers than comparable structures fabricated from Kevlar or aluminum. An accurate method predicting the energy-absorption capability of beams was developed. Farley, Gary L. and Boitnott, Richard L. and Carden, Huey D. Langley Research Center ...

Available in PDF, EPUB and Kindle. Book excerpt: Acquire the Life-Saving Skills Needed to Eliminate or Reduce Most Helicopter Accidents A vital resource for pilots, helicopter enthusiasts, and aircraft maintenance technicians, Fatal Traps for Helicopter Pilots analyzes all aspects of helicopter accidents, including flight basics, engineering, meteorology, flight training, and human factors. This life-saving guide shows how proper preparation can help prevent accidents by addressing causes such as aerodynamic problems, mechanical failures, poor loading, mid-air collisions, and more. Filled with case studies and first-hand accounts of accidents, the book organizes accident types by primary causes, presenting proven methods for eliminating or reducing the possibility of each type. Greg Whyte, an ex commercial helicopter pilot and professional aviation writer, draws on his own flying experiences and those of other flight veterans to provide a wealth of practical information and safety tips that are essential for everyone who flies, maintains or crews in helicopters. Filled with over 100 helpful illustrations, Fatal Traps for Helicopter Pilots enables readers to: Identify and address the common causes of helicopter accidents Explore in-depth examples of accident scenarios Examine the technical details of accident causes Review case studies and first-hand accounts of accidents Learn from the plain-English notes on avoidance and recovery Inside This Aviation Accident-Prevention Guide • Basic Flight Principles • Vortex Ring State • Recirculation • Ground Resonance • Retreating Blade Stall • Dynamic Rollover • Overpitching • Main Rotor Strikes • Mid-Air Collisions • Mast Bumping • Engine Failures • Tail Rotor Failures • Mechanical Failures • Fuel • Fire • Ditching • Loading Issues • Winching • Weather • Crew and Pre-flight Hazards • Human Factors • Training Mishaps
