Aeronautics and Aerospace Applications

In the field of cryotechnology, which includes, for example, transport and storage of liquefied gases or frozen biomedical specimens, aerogel insulation offers numerous 

The most typical space saving applicatitms in the building industry are as follows  

A current reference market price for a cubic meter of silica aerogel is on the order of US 4,000 (2008). With increasing commercialization, this value could drop below the US 1,500 mark by the year 2020. Lower prices will cause an equilibration or stabilization of the aerogels insulation market. The advance of organic and hybrid systems could invigorate this development process additionally. In the meantime, we shall look forward to seeing new aerogel insulation products and manufacturers appear on the markets.

The filament winding technology is used in the production of high performance composite structures for aeronautical and aerospace applications and also for more current applications, like pressure vessels or piping systems. 

Johnson et al. (15) reported the first attempt to synthesize PEEK by polycondensation of bisphenolate with activated dihalides using DMSO as a solvent and NaOH as a base. High molecular weight polymers were difficult to obtain due to the crystallinity and the resulting insolubility of polymers in DMSO. To circumvent the solubility problem, Attwood and Rose (16) used diphenyl sulfone as a solvent, and the polymerization was carried out close to the melting point. Victrex PEEK was commercialized by the British company ICI in 1982 using this method. Since its commercialization, this thermoplastic polymer has been used in a wide range of applications, from medicine to the electronic, telecommunications and transport industries (automobile, aeronautic and aerospace) (17,18). 

It was hard to even guess that the glycidylic compounds discovered by the Swiss chemist P. Kastan in the 1930s would become so significant in 20 years. Many industrial branches would become potential fields of application of these products. Glass fiber-reinforced plastics, a wide variety of adhesives, and numerous elec-troinsulating materials the aeronautics and aerospace industries, electronics, and... 

Advanced composites represent another major growth market. It is expected to reach 10 billion by the end of the next decade. Du Pont recently announced the formation of a new composites division to consolidate operations and business-planning functions. The company intends to participate in every step of the composites process, from the manufacture of reinforcing fibers and resins to the design and fabrication of finished products to replace metals in aeronautic, aerospace, and automative applications. Du Pont s families of engineering resins and industrial fibers give it an excellent springboard for this opportunity. 

During the past decades, progress in aeronautics and astronautics has been remarkable because people have learned to master the difficult feat of hypervelocity flight. A variety of manned and unmanned aircraft have been developed for faster transportation from one point on earth to another. Similarly, aerospace vehicles have been constructed for further exploration of the vast depths of space and the neighboring planets in the solar system. RPs has found numerous uses in specialty areas (ablation, insulation, etc.) such as hypersonic atmospheric flight and chemical propulsion exhaust systems. The particular RP employed in these applications is based on the inherent properties of the material or the ability to combine it with another component material to obtain a balance of properties uncommon to either component. 

Sohd oxide fuel cells (SOFC) are currently being developed for various applications in the automobile, power generation, aeronautic, and other industries. More recently, NASA has explored the possibility of using SOFCs for aero-propulsion under its Zero Carbon Dioxide Emission Technology (ZCET) Project in the Aerospace Propulsion and Power...

The original drive for the development of modem carbon fibers, in the late-1950s, was the demand for improved strong, stiff and lightweight materials for aerospace (and aeronautical) applications, particularly by the military in the West. The seminal work on carbon fibers in this period, at Union Carbide in the U.S.A., by Shindo, et al, in Japan and Watt, et al, in the U.K., is well-documented [4-7]. It is always worth pointing out, however, that the first carbon fibers, prepared from cotton and bamboo by Thomas Edison and patented in the U.S.A. in 1880, were used as filaments in incandescent lamps. 

Epoxy resins show better properties than those of polyester resins, for instance, good ultimate elongation, which is an extremely important factor for the mechanical properties of composites. On the other hand, they are more expensive and more complicated to be applied when compared to polyester. These are the reasons why epoxy resins are mainly used in technology-based fields such as aeronautics, aerospace, and sport. The high mechanical and bonding properties make epoxy resins the most commonly used resins for civil engineering applications. 

Aeronautics is the science of atmospheric flight. Aviation is the design, development, production, and operation of flight vehicles. Aerospace engineering extends these fields to space vehicles. Transonic airliners, airships, space launch vehicles, satellites, helicopters, interplanetary probes, and fighter planes are all applications of aerospace engineering.
