    All set for the future: New aircraft technologies are taking to the skies

    If you think flying today is exciting, you’re in for some special surprises as the aviation industry moves forward. Aircraft in the future might look like today’s planes, but they will be completely different in terms of the technology they will use.

    Future Aviation

    The aircraft of the future will be faster, quieter, and more comfortable.

    They will weigh less, too. More airframes will be made completely of woven mats of carbon embedded in plastic called “composites.” These materials offer both lightness and exceptional strength. Smooth, rivetless surfaces make for superior aerodynamics.

    Always online
    All aircraft will be connected to the worldwide web almost everywhere they fly, so passengers can use their cell phones and the Internet everywhere. Brand new Ka broadband technology makes for increased download speeds, so we can say goodbye to slow loading emails, and can even watch video more easily.

    We may even be able to forget the messages from the captain at the beginning of the journey. Pilotless passenger planes are now in flight test, such as the Centaur, a four-seat 4,100-pound turboprop. It could be in service testing pipelines within five years, and eventually pave the way for larger passenger types. As the public gets more used to driverless cars, it will also become more comfortable with the concept of flying in drones.

    Flying at supersonic speed
    We can also look forward to supersonic aircraft that can fly faster than the speed of sound. Several companies, including Airbus, are developing ultra rapid air vehicles, which can cruise supersonically at altitudes of more than 100,000ft and carry up to 20 passengers for 5,500 miles, saving time and fuel on long haul flights.

    More efficient flying
    A greener flying environment is on the horizon, too. GE Aviation is testing revolutionary new engines that will deliver supersonic speeds and fuel efficiency, and all the engine manufacturers are looking for a reduction in fuel consumption.

    Speaking of which, there are also international programmes in place creating bio-jet fuel from jatropha, camelina and micro-algae. Sustainable aviation fuels could provide up to one-third of all commercial aviation jet fuel by 2030 if produced in sufficient quantities.

    Airlines all over the world are buying up thousands of new aircraft, so air travel is definitely here to stay. It’s good to know, then, that flying will become greener and cleaner than it is today.

    WINGSWings develop the major portion of the lift of aheavier-than-air aircraft. Wing structures carry some ofthe heavier loads found in the aircraft structure. Theparticular design of a wing depends on many factors,such as the size, weight, speed, rate of climb, and use ofthe aircraft. The wing must be constructed so that itholds its aerodynamics shape under the extremestresses of combat maneuvers or wing loading.Wing construction is similar in most modernaircraft. In its simplest form, the wing is a frameworkmade up of spars and ribs and covered with metal. Theconstruction of an aircraft wing is shown in figure 4-8.Spars are the main structural members of the wing.They extend from the fuselage to the tip of the wing. Allthe load carried by the wing is taken up by the spars.The spars are designed to have great bending strength.Ribs give the wing section its shape, and they transmitthe air load from the wing covering to the spars. Ribtend from the leading edge to the trailing edge of thewing.In addition to the main spars, some wings have afalse spar to support the ailerons and flaps. Mostaircraft wings have a removable tip, which streamlinesthe outer end of the wing.Most Navy aircraft are designed with a wingreferred to as a wet wing. This term describes the wingthat is constructed so it can be used as a fuel cell. Thewet wing is sealed with a fuel-resistant compound as itis built. The wing holds fuel without the usual rubbercells or tanks.The wings of most naval aircraft are of all metal,full cantilever construction. Often, they may be foldedfor carrier use. A full cantilever wing structure is verystrong. The wing can be fastened to the fuselagewithout the use of external bracing, such as wires orstruts.A complete wing assembly consists of the surfaceproviding lift for the support of the aircraft. It alsoprovides the necessary flight control surfaces.NOTE:The flight control surfaces on a simplewing may include only ailerons and trailing edge flaps.The more complex aircraft may have a variety ofdevices, such as leading edge flaps, slats, spoilers, andspeed brakes.Various points on the wing are located by wingstation numbers (fig. 4-7). Wing station (WS) 0 islocated at the centerline of the fuselage, and all wingstations are measured (right or left) from this point (ininches).STABILIZERSThe stabilizing surfaces of an aircraft consist ofvertical and horizontal airfoils. They are called the4-8TRAILING EDGERIBSSPARSLEADING EDGEANf0408Figure 4-8.—Two-spar wing construction.
