The book describes the state of the art and latest advancements in technologies for various areas of aircraft systems. In particular it covers wide variety of topics in aircraft structures and advanced materials, control systems, electrical systems, inspection and maintenance, avionics and radar and some miscellaneous topics such as green aviation. The authors are leading experts in their fields. Both the researchers and the students should find the material useful in their work.
Air travel is continuing to experience the fastest growth among all modes of transport. Increasing total
fuel consumption and the potential impacts of aircraft engine emissions on the global atmosphere have
motivated the industry, scientific community, and international governments to seek various emissions
reduction options. Despite the efforts to understand and mitigate the impacts of aviation emissions, it still
remains uncertain whether proposed emissions reduction options are technologically and financially
Innovation in engineering often means the clever use of a new material - new to a
particular application, but not necessarily (although sometimes) new in the sense of
‘recently developed’. Plastic paper clips and ceramic turbine-blades both represent
attempts to do better with polymers and ceramics what had previously been done well
with metals. And engineering disasters are frequently caused by the misuse of
Engineering technology or mechanical engineering industry is the application of physical principles to create all kinds of machinery and equipment or other useful objects. Mechanical application of thermodynamic principles, the law of conservation of mass and energy to analyze static and dynamic physical systems, for design work in areas such as automotive, aircraft and the other vehicles, heating systems and cooling, household appliances, machinery and production equipment, weapons ...
Written for students of aeronautical engineering and based on a range of detailed aircraft design projects, this wide-ranging book draws together the elements of aircraft design and will support any aircraft design project. Written by experienced U.K. and U.S. based authors this is a unique resource that opens up the initial design process, explores the experience of others on similar projects, and clarifies the processes that are behind the equations and calculations used in aircraft design.
During my experience of teaching aircraft structures I have felt the need for a textbook
written specifically for students of aeronautical engineering. Although there
have been a number of excellent books written on the subject they are now either
out of date or too specialist in content to fulfil the requirements of an undergraduate
Aircraft wake (photo courtesy of Cessna Aircraft Company). This photograph first appeared in the Gallery of Fluid Motion, Physics of Fluids (published by the American Institute of Physics), Vol. 5, No. 9, Sept. 1993, p. S5, and was submitted by Professor Hiroshi Higuchi (Syracuse University). It shows the wake created by a Cessna Citation VI flown immediately above the fog bank over Lake Tahoe at approximately 313 km/h. A r r f altitude was about icat 122 m above the lake, and its mass was approximately 8400 kg. The downwash caused the trailing vortices to descend over the fog layer...
The introduction of the technology for bonded composite repairs of metallic
airframe structures could not have come at a more opportune time. Today, many
countries are facing the challenge of aging aircraft in their inventories. These
airframes are degrading due to damage from fatigue cracking and corrosion.
Repair with dependable techniques to restore their structural integrity is
mandatory. The concept of using bonded composite materials as a means to
maintain aging metallic aircraft was instituted in Australia approximately thirty
Acoustic fatigue is due to a very high intensity excitation as a result of pressure
waves caused by either engine or aerodynamic effects. Acoustically-induced
cracking has occurred on the external surface of the lower nacelle and aft fuselage
skins on the F/A-18, as illustrated in Figure 19.1. In the former region, overall
sound pressure levels greater than 170dB have been measured in flight [l]. These
high sound pressure levels appear to be a result of an aerodynamic disturbance at
the inlet lip....
In recent years, the affordability of weapon systems has become increasingly important to policymakers in the Department of Defense and U.S. Congress. Aerospace industry analysts and some government officials have asserted that government cost estimates are based on outdated methods that do not account for the latest technological innovations. The authors of this report present the results of a RAND research study to update the methods for estimating military jet engine costs and development time.
Technological improvements might also involve the adoption and use of alternative fuel or
alternative propulsion vehicles. In developing countries, the most commonly discussed
alternative vehicle strategies include compressed natural gas (CNG), liquefied petroleum gas
(LPG), alcohol-based fuels, and electric propulsion or hybrid -electric vehicles in certain
applications. Other alternative fuels showing potential long -term promise in the transport sector
include hydrogen fuel cells and various synthetic fuels for use in compression-ignition engines.
Systems engineering and program management (SE/PM) constitute a large portion of the acquisition cost of military aircraft and guided weapons systems. The goal of this study was the development of a set of cost-estimating relationships that can be used to estimate the SE/PM cost element for development and
