MAKING OF CHUCK GLIDER

MAKING OF CHUCK GLIDER

Objective

1.  Build a glider.
2.  Learn how to change the flight characteristics of a glider.

Different wing platforms’

The early jet aircraft had straight wings, wings that angled (swept) toward the tail, triangular (delta) wings, and wings that could be moved in-flight to change the angle of backward sweep. Each design added to our knowledge of high-speed flight. More recently, aircraft designs have incorporated wings that sweep forward and even wings that sweep forward and backward at the same time. Made use of small wing-like control surfaces called canards which are located ahead of the main wings.

The templates on this poster allow students to build and experiment with all of these basic wing/tail/canard configurations. Eight different plastic foam “gliders” can be built using these templates, but the total number of variations is only limited by the imagination of the “designer.”

Materials for building airplanes must be lightweight, strong, and readily available. These qualities make plastic foam a good material for the construction of flying models. Most real airplanes are made from another lightweight, strong, and readily available material called aluminum.

Materials Required

•  Plastic foam food tray,
•        About 28 cm X 23 cm (Size 12)
•   Cellophane tape
•   Paper clips
•  Binder clips
• Ball point pen
• Plastic knife or scissors
• Toothpicks
• Goggles (eye protection)
• Emery boards or sandpaper

Procedure

1. Understand the template keys.

2. Take plastic foam tray and copies of the glider templates.

3. Write the name of each airplane part on the template.

4. Tape the glider template to the food tray.

5. Cut out the airplane parts using the templates. Plastic foam can be cut using Scissors, a razor knife, or a serrated plastic knife. It can also be cut using a sharp pencil or round toothpick to punch a series of holes approximately 2mm apart around the outside edge of the part. The part can then be pushed out from the tray.

6. If there are any rough edges around a part, they can be smoothed using Sandpaper or an emery board.

7. Carefully cut a slot in the fuselage. Slide other parts into it to finish the glider.

(Another fuselage is needed to make the “twin fuselage” glider.)

Techniques

1. An airplane’s weight must be properly balanced for it to fly safely. The same "weight and balance" principles apply to models. We can determine the proper weight and balance by attaching a paper clip or binder clip to the fuselage. We should vary the position of the clip with each flight until the glider flies the greatest distance in a straight line. Additional clips might be needed to improve the glider’s flight performance.

2. Weight and balance is also determined by the position of the wings, canards, and other surfaces along the fuselage. As per my point of view; move the wings, stabilizers, and canards to different positions in the fuselage to determine the settings that make the glider fly best.

3. Measure and record the distance of each flight, and compare the results with each change in the glider’s weight and balance.
