This book was released on 2018-09-27 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: An eight-inch-long (0.2 m) crack was found in an external fuel-tank pylon of a U.S. Coast Guard HH-60 helicopter. The damaged pylon was removed from service and destructively examined at NASA Langley Research Center (LaRC) to determine the cause of the crack. Results of the analysis revealed that crack initiation occurred at corrosion pits in a fastener hole and crack propagation was a result of cyclic loading.

Book Synopsis Failure Analysis of Helicopter External Cargo-Handling Systems by : Robert E. Hunt
Download or read book Failure Analysis of Helicopter External Cargo-Handling Systems written by Robert E. Hunt and published by . This book was released on 1973 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the failure of helicopter cargo-handling systems was conducted. A data search and compilation were completed from which the external cargo-handling system was defined and the system operation explained. Operational parameters were also defined and explained. Also criteria for assessing failures were established, data sources were cited, a search plan outlined, and failure data and consensus data were retrieved and categorized. The data were taken primarily from cargo helicopters deployed in Vietnam. Their overall utilization, load categories, and rigging materials were determined, and a consensus summary of the cause of specific failures was compiled and documented. A data analysis was conducted with the relationship of failure occurrences and rates determined for specific types of accidents and failures. Predominant causes of failures were analyzed, a cost/value of relationship of cargo dropped established, and projections of the heavy-lift helicopter as a cargo carrier were made. Candidate corrective actions were recommended, with the development of specific corrective actions made, encompassing a collapsible cargo net-pallet concept and an investigation of cargo hook design principles.

Available in PDF, EPUB and Kindle. Book excerpt: This test was conducted to analyze failures that occurred in the airborne pressurization system of missiles 4C and 11D. The objective of the test was to determine if heating of the motor section pressure/bleed line on the regulator would result in a condition similar to that which caused the failures. (Author).

Book excerpt: Unlike most engineers, system engineers focus on the knowledge base needed to develop good systems in a cross-functional fashion rather than deeply on isolated topics. They are often said to be a mile wide and an inch deep in what they do know. System Synthesis: Product and Process Design provides insight into complex problems, focusing on the boun

Download or read book Lightning Protection of Aircraft written by Franklin Fisher and published by CreateSpace. This book was released on 2012-07-13 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to present under one cover the current state of knowledge concerning the potential lightning effects on aircraft and that means that are available to designers and operators to protect against these effects. The impetus for writing this book springs from two sources- the increased use of nonmetallic materials in the structure of aircraft and the constant trend toward using electronic equipment to handle flight-critical control and navigation function.

Download or read book Gradual failure : the air war over North Vietnam 1965-1966 written by Jacob Van Staaveren and published by DIANE Publishing. This book was released on 2002 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the many facets of the American war in Southeast Asia debated by U.S. authorities in Washington, by the military services and the public, none has proved more controversial than the air war against North Vietnam. The air war s inauguration with the nickname Rolling Thunder followed an eleven-year American effort to induce communist North Vietnam to sign a peace treaty without openly attacking its territory. Thus, Rolling Thunder was a new military program in what had been a relatively low-key attempt by the United States to win the war within South Vietnam against insurgent communist Viet Cong forces, aided and abetted by the north. The present volume covers the first phase of the Rolling Thunder campaign from March 1965 to late 1966. It begins with a description of the planning and execution of two initial limited air strikes, nicknamed Flaming Dart I and II. The Flaming Dart strikes were carried out against North Vietnam in February 1965 as the precursors to a regular, albeit limited, Rolling Thunder air program launched the following month. Before proceeding with an account of Rolling Thunder, its roots are traced in the events that compelled the United States to adopt an anti-communist containment policy in Southeast Asia after the defeat of French forces by the communist Vietnamese in May 1954.

Download or read book Sierra Hotel : flying Air Force fighters in the decade after Vietnam written by and published by DIANE Publishing. This book was released on 2001 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 1999, only a few weeks before the U.S. Air Force spearheaded NATO's Allied Force air campaign against Serbia, Col. C.R. Anderegg, USAF (Ret.), visited the commander of the U.S. Air Forces in Europe. Colonel Anderegg had known Gen. John Jumper since they had served together as jet forward air controllers in Southeast Asia nearly thirty years earlier. From the vantage point of 1999, they looked back to the day in February 1970, when they first controlled a laser-guided bomb strike. In this book Anderegg takes us from "glimmers of hope" like that one through other major improvements in the Air Force that came between the Vietnam War and the Gulf War. Always central in Anderegg's account of those changes are the people who made them. This is a very personal book by an officer who participated in the transformation he describes so vividly. Much of his story revolves around the Fighter Weapons School at Nellis Air Force Base (AFB), Nevada, where he served two tours as an instructor pilot specializing in guided munitions.
