0516312???Question?Ina windy and sunny afternoon, Jack and his son went for kite flying.When Jack bought a kite, the boss told him that if he wants to flythe kite fairly and highly, he needs to know how to control the kitestring. As an engineer, Jack thought maybe he could figure out othermore concrete solutions to compute how much power he needs to fly akite step-by-step, for getting the best result. Known?Akite gains lift while there is wind blowing up the kite, the surfaceof the kite touch the moving air and generate lift force to the kite,so that a kite airborne.There are some ways to make kite float onthe air. Sincea kite need to act against its own weight in order to reduce itsforce, player should give enough force to the kite to climb.
The steady wind speed for flying akite is the main consideration during kite flying among otherdifferent factors that may change the amount of liftgenerated.Before releasing the kite to lift, hold it in thedirection of a tailwind rather than a head wind. This action can helpto provide some physical energy to fly a kite, and just simply tug itto rise in the air. So that the proper velocity of wind can provideenough power, to support and maintain the kite to aviate, as thehigher the altitude between the ground and the kite, the faster thewind blows.
The kite will continue to fly up to the sky, after thekite is successfully being launched. To keep the kite cruise, it isimportant to control and balance the tension of pulling the rope andthe height of the flying kite.The lift of the flight increase, ifthe tug are being pulled to gain extra and faster wind speed. Thiswill make the kite float higher and stay in good condition.Naive solution?Bruteforce method. List all the possible pares, and compute themindividually.
After getting all the results, choose the optimal one.My solution?Byapplying the way of linear programming. After knowing the balancedrelationship between wind speed and tug force, we can get the mostfavorable solution by applying greedy algorithms.Bythe result found from the above solutions, a programmed machine couldbe installed on the kite handle, as well as a light-weight wind speedsensor on the wings of the kite.
The wind speed sensor will be linkedto the machine for the data transfer, wirelessly reporting it’sreal-time wind-speed which has been detected. The programmed inputthe recorded wind-speed for the machine to compute the value of thetension to pull the tethers, and this output will be shown on themonitor. Finally, we can modify the pulling force by the value on themonitor.
