Question

Progressions of Models of Airplanes

Answer 1

Answer:

A model aircraft is a small sized unmanned aircraft or, in the case of a scale model, a replica of an existing or imaginary aircraft. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models.

Flying models range from simple toy gliders made of card stock or foam polystyrene to powered scale models made from materials such as balsa wood, bamboo, plastic, styrofoam, carbon fiber, or fiberglass and are skinned with tissue paper or mylar covering. Some can be very large, especially when used to research the flight properties of a proposed full scale design.

Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many models are available in kit form, typically made of injection-moulded polystyrene.

Aircraft manufacturers and researchers also make wind tunnel models not capable of free flight, used for testing and development of new designs. Sometimes only part of the aircraft is modelled.

Explanation:

Static model aircraft (i.e. those not intended to fly) are scale models built using plastic, wood, metal, paper, fiberglass or any other suitable material. Some static models are scaled for use in wind tunnels, where the data acquired is used to aid the design of full scale aircraft.

Models are available that have already been built and painted; models that require construction, painting and gluing; or models that have been painted but need to be clipped together.

Answer 2

Progression of Models of Airplanes.

• Over the last century, aeroplanes have come across a drastic change moreover it has gone through various evolution.
• Our dependence on air travel over the years has forced aeroplane design to develop with the times.
• the modern aircraft uses only jet engines which have helped to increase the average speed of aeroplanes, aircraft wings have also been shortened to produce less drag.
• The general flight phases are divided into the planning phase, takeoff phase, climb phase, cruise phase, descent phase, approach phase, and taxi phase.
• Some of the first planes weren't used to carry people, but instead to carry mail.
• The modern aeroplanes are made with aluminium while the pilot of the 1903 Wright Flyer lay in the middle of the plane and used wing warping to control.
