Curiosidade:
Na sala 22 do Museu Egípcio no Cairo, há um objeto
de madeira que aparenta ser um avião moderno ou planador. De fato, é tão
semelhante que alguns acreditam ser esta a prova de que os egípcios antigos
possuíram a tecnologia de vôo. O artefato é feito de madeira, tem comprimento de
5.6 polegadas (14.2 cm) e envergadura de 7.2 polegadas (18.3 cm). Foi encontrado
em uma tumba perto de Saqqara em 1898 e foi datado aproximadamente 200 A.C.

Alternative fuel options
There are
a number of alternative fuel options for aviation. The main two criteria for
optimum fuel efficiency are:
·
Aircraft need to
be lightweight and have low drag (as well as efficient engines and wings)
·
Aircraft fuel
needs to have a high energy content per unit volume and weight
Synthetic liquid fuels:
Synthetic fuel or synfuel is any liquid fuel obtained from coal, natural gas or
biomass. It can sometimes refer to fuels derived from other solids such as oil
shale, tar sand, waste plastics or from the fermentation of biomatter.
The leading
company in the commercialization of synthetic fuel is Sasol, a company based in
South Africa. Sasol
currently operates the world's only commercial coal-to-liquids facility at
Secunda, with a capacity of 150,000 barrels a day. Other companies that have
developed coal- or gas-to-liquids processes (at the pilot plant or commercial
stage) include Sasol, Shell, Exxon, Statoil, Rentech, and Syntroleum.
Bio-jet fuel:
jet fuels made from converted agricultural oil crops like soya. Ethanol
fuel: can be combined with gasoline in any concentration up to pure ethanol
(E100). Ethanol is, by far, mostly used to power cars, but it may be used to
power other vehicles, like farm tractors and perhaps in the future, airplanes.
Hydrogen: The use
of hydrogen in aviation is expected to start with fuel cell applications for the
replacement of Auxilliary Power Units (APUs), ram air turbine (RAT) and
distributed power units. These applications will generate large fuel savings on
the ground, lower noise and lower NOx.
