Up up and away Soar like a bird in a 21st century version of the Wright brothers’ groundbreaking invention, so many believed wouldn’t fly WE take the sight of planes crisscrossing the sky for granted, but it is only a recent phenomenon in human history. For thou- sands of years, only birds took wing and all man could do was dream of one day taking to the skies. Attempts to fly From early humans flapping their arms to mimic the flight mechanics of birds, to the Chinese discovery of kites in 400BC, to Leonardo da Vinci’s designs for an ornithopter during the 1500s, to the Montgolfier brothers’ historic hot air balloon flight in 1783, to the many diffe- rent versions of gliders, the foundations flight were being laid. For a feasible flying machine to be created the science of flying had to be understood. After constructing and test- ing a wide variety of flying machines, in 1903 the first successful, powered, piloted flight in history was achieved by the Wright brothers. Humankind was now able to fly and there was no stopping the development of aviation. Forces that act upon planes Have you ever seen the wind pick up a leaf or feather and carry it through the air? Planes have engines that make their own wind so they can fly. As the engines push the plane forward, this movement creates air flow moving over and under the wings. The wings on a plane are a special shape – curved on top and flatter underneath. The shape of the wings makes the air flow faster over the top of the wing. The faster the air moves, the lighter the air pressure. Planes and other aircraft that travel in straight level flight have four forces that affect them: drag, gravity, thrust and lift. ● Drag: air resistance at the back of the plane that slows forward movement. ● Thrust: force that moves a plane forward through the air. Thrust is creat- ed by a propeller or a jet engine. ● Gravity: pulls all objects towards Earth. ● Lift is the force created by the move- ment of air above and below a wing. Gravity is the opposite of lift, and drag is the opposite of thrust. When all four forces are in balance the plane remains level. When one or more of these four forc- es change, the plane changes its height, direction or speed. AUSSIES IN THE AIR In terms of air distance and prominent aviation pioneers, Australia has led the way in aviation. The vast size of our country meant pioneers developed manned and powered flight establishing passenger and cargo transport, airmail, medical, as well as search and rescue services. Lawrence Hargrave paved the way with his box-kite. HAVE you ever come across a word in the newspaper that you haven’t seen before or don’t know what it means?

Cut cardboard into two strips. One 2.5cm wide and 30cm long and one 2.5cm x 13cm. 2. Overlap the ends of each strip by 2cm and tape together to make two loops – one big, one small. 3. Set the straw inside the smaller loop so that the end sticks outside the loop. Tape the straw inside. 4. Tape the other end of the straw to the inside of the large loop, making sure the straw is set evenly so the flying machine is balanced. 5. To fly your machine hold it between your thumb and forefinger and toss it in the air at an upward angle. News in the Spotlight Another Aussie record An Australian pilot has broken the record for the youngest person to fly a single-engine aircraft solo around the world. When 19-year-old Ryan Campbell (pictured below) landed his plane The Spirit of the Sapphire Coast in Wollongong on September 7 he completed an epic feat that saw him rewrite the record books. Seventy days after setting off on his journey, the teenager arrived back in Australia having taken a route over deserts, glaciers, oceans and volcanoes. Piloting a specially-modified single-engine Cirrus SR22, Campbell made 34 stops in 15 countries and spent 200 hours in the air. Campbell follows in the slipstream of Charles Kingsford Smith, and Bert Hinkler.
