Human beings have always had a fascination with flying, and this has served as an impetuous for design of all types of devices that will fulfil their dreams (Abzug, 2002, Pp. 1 – 10).
1 – 5). Thus, a capacity for flying over the longest possible distance on limited power available from humans is a critical measure of performance for small human powered aircraft and jump type hang gliders, which must maintain a low weight while ensuring a degree of stability, safety, controllability and structural soundness. Because one of the largest weight components of an aircraft is its primary structure, the proper design of aircraft structure for human powered aircraft and hang gliders remains a challenge that decides about the success or failure of a design. The appropriate design flight conditions and the structural loads caused by a flight are variable and not immediately apparent, with flight regime and manoeuvring requirements placing additional demands on aircraft structures. Thus, for hundreds of years, if not thousands, the idea of man-powered flight has inspired many brave men to design strange contraptions with which to rival the birds (Grosser, 2004, Pp. xvii – xix).
The International Worthing Birdman Competition is an annual event held in the picturesque Worthing Town, located on England’s South Coast that encourages creativity in design and innovation for human powered / glider type flying machines (Worthing Birdman, 2011,” Worthing International Birdman Festival”). ...
