Aircraft Noise: Assessment, Prediction and Control

adminpai — Thu, 02 Sep 2021 17:19:45 +0000

Aircraft noise has adverse impacts on passengers, airport staff and people living near airports, it thus limits the capacity of regional and international airports throughout the world. Reducing perceived noise of aircraft involves reduction of noise at source, along the propagation path and at the receiver.

Effective noise control demands highly skilled and knowledgeable engineers. This book is for them. It shows you how accurate and reliable information about aircraft noise levels can be gained by calculations using appropriate generation and propagation models, or by measurements with effective monitoring systems. It also explains how to allow for atmospheric conditions, natural and artificial topography as well as detailing necessary measurement techniques.

Just ten days after Alan Shepard Jr. became America’s first man in space on May 5, 1961, President John F. Kennedy challenged the nation, suggesting that the United States should land a man on the moon by the end of the decade. The ambitious goal of Project Apollo required a series of intermediate steps, which were to be explored by Project Gemini. Created on January 3, 1962, Project Gemini’s objectives were many. During ten manned flights in 1965 and 1966, astronauts would perform spacewalks, rendezvous with orbiting vehicles using maneuvering and propulsion systems, and perform docking tests. A great deal of experience was gained and equipment tested, and with one exception – a dry land capsule landing – all of the planned objectives were met. All ten manned flights were made using Titan II two-stage boosters that were purpose-built for Gemini and known as “GLV” or Gemini-Titans. The prime contractor for the Mercury capsule McDonnell Aircraft, constructed the two-man Gemini capsule. A larger, more sophisticated spacecraft than Mercury, the Gemini capsule relied on a detachable Equipment Module for power, propulsion, and life-support systems. The capsule itself was outfitted with ejection seats, carried an on-board Guidance Computer, and could be flown in six directions. Created by NASA and contractor McDonnell Aircraft, this Familiarization Manual explains all the systems aboard the Mercury space capsule including cabin controls, sequence, electrical power, cooling, guidance and control, communications, retrograde rocket, and landing systems and procedures. Dating from September of 1965 for the long range and extended missions, it represents a late revision of documents created at the beginning of the Gemini program. Originally restricted, this manual has been declassified and is presented in its entirety, running nearly 600 pages.

Analysis of Aircraft Structures: An Introduction

adminpai — Thu, 02 Sep 2021 17:19:45 +0000

As with the first edition, this text provides a clear introduction to the fundamental theory of structural analysis as applied to vehicles, aircraft, spacecraft, automobiles, and ships. The emphasis is on the application of fundamental concepts of structural analysis in everyday engineering practice. No assumptions are made with regard to the method of analysis. All approximations are accompanied by a full explanation of their validity. Repetition is an important learning tool, and so some redundancy appears to dispel misunderstanding. The number of topics covered in detail is limited to those essential for modern structural engineering practice. In this new edition, more topics, figures, examples, and exercises have been added. A primary change has been a greater emphasis on the finite element methods of analysis. Three new chapters are now included, and clarity remains the hallmark of this text.

The DelFly: Design, Aerodynamics, and Artificial Intelligence of a Flapping Wing Robot

adminpai — Thu, 02 Sep 2021 17:19:44 +0000

This book introduces the topics most relevant to autonomously flying flapping wing robots: flapping-wing design, aerodynamics, and artificial intelligence. Readers can explore these topics in the context of the “Delfly”, a flapping wing robot designed at Delft University in The Netherlands.

How are tiny fruit flies able to lift their weight, avoid obstacles and predators, and find food or shelter? The first step in emulating this is the creation of a micro flapping wing robot that flies by itself. The challenges are considerable: the design and aerodynamics of flapping wings are still active areas of scientific research, whilst artificial intelligence is subject to extreme limitations deriving from the few sensors and minimal processing onboard.

This book conveys the essential insights that lie behind success such as the DelFly Micro and the DelFly Explorer. The DelFly Micro, with its 3.07 grams and 10 cm wing span, is still the smallest flapping wing MAV in the world carrying a camera, whilst the DelFly Explorer is the world’s first flapping wing MAV that is able to fly completely autonomously in unknown environments. The DelFly project started in 2005 and ever since has served as inspiration, not only to many scientific flapping wing studies, but also the design of flapping wing toys.

The combination of introductions to relevant fields, practical insights and scientific experiments from the DelFly project make this book a must-read for all flapping wing enthusiasts, be they students, researchers, or engineers.

Stratonauts: Pioneers Venturing into the Stratosphere

adminpai — Thu, 02 Sep 2021 17:19:44 +0000

Just what does it take to be a stratonaut, soaring to higher and higher altitudes of Earth’s atmosphere? Brave men and women have reached extreme heights in balloons, aircraft and rocket ships over the past two centuries, from the first untethered balloon flight to the first flights in the newly defined stratosphere, through to the present flights that continue to set new records. This book defines the altitudes related to the stratosphere, how it changes with latitude and the effects on ascending aviators. Also described is how over time technology enabled aircraft and balloons to achieve higher altitudes. The book shows the clear influence of the military on designs that initially focused on speed and maneuverability, but only later on reaching new altitudes. The early flights into the troposphere and eventually the mid to upper reaches of the stratosphere are chronicled, with great emphasis on flight operations. This includes decompression, bailouts, inertia coupling, ejections, catastrophic disintegration, crashes and deaths. Although the book highlights major altitude attempts and records, it also focuses on the life-threatening problems confronting the would-be stratonaut and the causes of many of their deaths. In doing so, it tries to define just what it takes to be a stratonaut.

NASA’s First Space Shuttle Astronaut Selection: Redefining the Right Stuff

adminpai — Thu, 02 Sep 2021 17:19:33 +0000

Unofficially they called themselves the TFNG, or the Thirty-Five New Guys. Officially, they were NASA’s Group 8 astronauts, selected in January 1978 to train for orbital missions aboard the Space Shuttle. Prior to this time only pilots or scientists trained as pilots had been assigned to fly on America’s spacecraft, but with the advent of the innovative winged spacecraft the door was finally opened to non-pilots, including women and minorities. In all, 15 of those selected were categorised as Pilot Astronauts, while the other 20 would train under the new designation of Mission Specialist. Altogether, the Group 8 astronauts would be launched on a total of 103 space missions; some flying only once, while others flew into orbit as many as five times. Sadly, four of their number would perish in the Challenger tragedy in January 1986.

In their latest collaborative effort, the authors bring to life the amazing story behind the selection of the first group of Space Shuttle astronauts, examining their varied backgrounds and many accomplishments in a fresh and accessible way through deep research and revealing interviews. Throughout its remarkable 30-year history as the workhorse of NASA’s human spaceflight exploration, twice halted through tragedy, the Shuttle fleet performed with magnificence. So too did these 35 men and women, swept up in the dynamic thrust and ongoing development of America’s Space Shuttle program.

“This book on the Group 8 Astronauts, the TFNGs, is an excellent summation of the individuals first selected for the new Space Shuttle Program. It provides insight into what it took to first get the Space Shuttle flying. For any space enthusiast it is a must read.”

– Robert L. Crippen PLT on STS-1

“As a reader, I had many moments where long, lost memories of the triumph and tragedy of the space shuttle program were brilliantly reawakened at the turn of a page. Loved it! This is a must-have book for every space enthusiast’s library.”

– TFNG Mission Specialist Astronaut Richard ‘Mike’ Mullane, author of Riding Rockets: The Outrageous Tales of a Space Shuttle Astronaut

“Many of the anecdotes in the book brought back memories of challenges, opportunities, and a team of men and women who were committed not just to the space program, but to one another…I’ve gone back to it several times as a reference source.”

– TFNG Steve Hawley, 5-time Space Shuttle Mission Specialist Astronaut

“The TFNG book is incredible and amazingly thorough! The detail in the book is awesome! It is my go-to book for any of the details I’ve forgotten.”

– TFNG Dr. Rhea Seddon, 3-time Space Shuttle Mission Specialist Astronaut.

“I can’t believe how detailed and complete it is!!! FANTASTIC work!!!”
