Advances in Rotorcraft Crashworthiness: Trends Leading to Improved Survivability 37th Alexander A. Nikolsky Honorary Lecture

Abstract

This paper documents progress in rotorcraft crashworthiness research and development that has been realized during the past forty years. Trends are presented in several categories including: facilities and equipment for conducting crash testing, updated crash certification requirements, the application of crash modeling and simulation techniques, and rotorcraft structural design for improved crash performance focusing on the application of advanced composite materials. Likely one of the most important advances is the ability to rapidly simulate crash impacts and to see the effects of design changes on the impact response. Enhanced dynamic computer simulations have greatly improved automotive safety today and are making inroads in the aerospace community. Consequently, a detailed discussion of advances in crash modeling and simulation is presented. The paper concludes with a list of suggested recommendations, such that the progress made to date can be continued into the future.

A Structural Design of a Child Seat Based on Morphological Elements and Ergonomics

“…With the help of processing development language, Jackson realized the visualization of human movement process and the real-time transmission of data. And for designer users, real-time statistical analysis and visualization are realized [ 12 ]. The categories of existing sitting posture detection algorithms and their advantages and disadvantages are analyzed in detail.…”

Development of method of testing a set of screen-exhaust devices in the helicopter Mi-8MSB-B

“…А тактико-технічні характеристики досліджених схем ЕВП не наводяться. Виключенням є робота [11], автор якої запропонував нові підходи у вирішенні живучості літального апарату, в тому числі, за рахунок інтеграції ЕВП в склад силової установки запропонованої нової конструкції бойового вертольоту.…”

Validation of Numerical Models of a Rotorcraft Crashworthy Seat and Subfloor

“…In particular, a significant effort has been made to study rotorcraft crashworthiness in the past four decades. A thorough synthesis of the most relevant activities can be found in [10]; this paper deals with all the main aspects, starting from accident statistics and then describing experimental test facilities, numerical modeling tools and techniques, design solutions and recommendations. The reader can easily find many aspects in common with automotive crashworthiness.…”
