The Boeing 777 is the first jetliner to be 100 percent digitally designed using three-dimensional computer graphics.
Throughout the design process, the airplane was "pre-assembled" on the computer, eliminating the need for a costly, full-scale mock-up.
The airplane is larger than all other twinjet or trijet airplanes and smaller than the 747.

A 350 : Airbus A350 is a Long-range airliner. Airbus has listened to its customers, who were interested in the medium size category with greater range
to complement their current Airbus wide-body families. There would be the A350-800 and A350-900, based on the A330-200 and A330-300 respectively, the cabin of the A350 will be 3 inches wider than the A330 ,but with range increases of 1000 miles or more.
The A350 is based on the A330, but with substantial improvements so that Airbus now claims its nearly a new aircraft.

F-35 :America's newest combat aircraft, the F-35 Joint Strike Fighter (JSF) will be manufactured by Lockheed Martin .
The Lockheed Martin team includes Northrop Grumman, BAE Systems, Pratt & Whitney and Rolls-Royce. Major subassemblies will be produced by Northrop Grumman. BAE Systems is
responsible for aft fuselage horizontal and vertical tails and the wing-fold mechanism, using experience from the Harrier STOVL programme.The F-35 family
designated the F-35A, F-35B and F-35C which are similar in shape and size and power by the same basic engine.

Aircraft Propellers :Thrust is generated by the propulsion system of the aircraft.
There are different types of propulsion systems develop thrust in different ways, although it usually generated through some application of Newton's Third Law.
Propeller is one of the propulsion system. The purpose of the propeller is to move the aircraft through the air

Helicopter : A typical helicopter has two sets of rotors. The main set commonly called the main rotors,
has upwards of two or more seperate blades and provides the lift for flight. The second set are much smaller and mounted vertically on the end of the helicopter's tail boom. This set is normally
refered to as the anti-torque rotor or tail rotor. The function of this tail rotor is to counter the torque produced by the powered main rotor

Airplane: It was , of couse, the birds who were responsible for the whole complicated story . A man with the brain of a scientist began to think seriouly about attainment of the dream.
This was Leonado da Vinci (1452-1519).There are four forces acting on the airplane all the time during airplane is flying.The four forces are: (1) Lift, (2)Gravity force or Weight, (3)Thrust, and (4) Drag.
