Introduction:

The design requirement for the launcher device is to design a launcher that can launch paper airplanes to a distance of 20 meters and launch it. The tolerance of the device should not exceed the width 12” of the system frame. Also, the length of the launcher should be 7” or less. The parameters of interest of launcher device are speed, distance, acceleration, dimension and time.The predicted performance of the launcher device is to launch the paper airplane with speed up to 28.28 m/s. The angular velocity was calculated to be 5400 rpm in order to reach the distance of 20 meters. The power needed to supply the motors is 2.49 watts. The required acceleration is 3.54 m/s^2. Finally, the expected time to launch the paper airplane is 0.01 second. The data acquisition was collected physically. Measuring tap was used to measure the distance that the paper airplane reached to. To measure the time, stopwatch was used to record the time when the paper launched until it hit the ground. From there, the velocity and acceleration were calculated using the formula V= d/t, d being the distance, and t being the time and A=v/t, v being the velocity and t being the time. The schedule shows test demo 1 and 2. Test demo 1 is about the maximum distance of the paper airplane made by the machine. Test demo 2 is about the distance, acceleration, velocity, and time of the paper airplane that made by the machine vs. the hand. Gantt chart shows the date of each test in the report appendix E.

Test Procedure:

•  

• The approximate time to complete the speed test of each flight is 5-15 minutes.

•  

• The test can take a place at the Hogue building exhibit area in front of the machine lab.

•  

• The speed test required a group of two or three to operate the machine, and record data

•  

•  

•  

Equipment: 

A4 papers, tap measure, stopwatch and notebook.

Procedure:

      1. Make sure the launcher battery are fully charged. 

      2. Set the top frame on the four legs and secures

          them with the screws. 

      3. Insert the paper in the loading to fold the paper

          and when the folding process is done and the

          paper airplane is completely free to launch, turn

          on the launcher switch on showing in the right picture.

      4. Start the stopwatch once the paper airplane starts

          to launch and then stop the stopwatch when the

          paper hit the ground.  

      5. Turn the launcher switch off when it is not in used. 

      5. Measure the flight distance where the paper

          airplane falls. 

      6. Record the time in second and the distance in meter.

      7. Repeat the steps 3-6 three times and calculate the speed of each flight using V= D/T, D being 

          distance, and T being time.

Safety:

Don’t stand of the launcher so the paper does not hit you. There is no other safety issue to concern about this test.

Discussion:

Depending on the design of the paper airplane determines its ability for speed, distance, accuracy, and performance. The airplane models with the larger wing area flew greater distances. The longer based and larger wing designs flew fastest.
