Even a schoolchild who does not miss classes in a school aircraft modeling circle is quite capable of building an airplane out of wood. Such a model of a glider, of course, is unlikely to be able to take passengers on board, but it will reward the creator with excellent flight properties and high structural strength. Launching a wooden glider will give you the experience of adjusting free-flying models and an unforgettable DIY flight experience.
It is necessary
Pine slats, knife, jigsaw, plane, PVA glue, aluminum wire, polystyrene, balsa, lavsan film, iron with thermostat
Instructions
Step 1
Start working on the wooden airplane model by assembling the frame. Glue it from pine slats with a section of 5x5 mm using PVA glue. After the glue is dry, reinforce the frame with styrofoam inner corners. Cut the upper end of the keel out of a piece of foam or balsa with a knife. Round off the front and back edges of the frame. Cover the keel with colored lavsan film on both sides. Glue the rudder to the trailing edge (you can cut it out of 0.5mm thick cardboard).
Step 2
Also, assemble a stabilizer from pine slats with a cross section of 5x5 mm. Strengthen it with foam corners, rounding the edges of the frame. Bend the end parts of the stabilizer with wire (an aluminum knitting needle or a piece of electrical wire will do). Tie the tip to the frame with threads with PVA glue or epoxy resin. Cover the finished stabilizer with a thin polyester film, like the keel.
Step 3
The wing is completely made of pine wood. The leading and trailing edges of the wing should have a section of 3.5x9 mm, the spar - 3.5x7 mm. Also make the ribs from a pine blank or linden. After the frame is assembled, cut the edges along the wing profile and round off.
Step 4
The fuselage is made of a pine lath with a section of 10x15 mm. The strip should thin out evenly along its entire length towards the tail. Cut the spout out of linden or pine. You will also need a balancing weight made from a piece of lead. Insert the weight into the hole in the spout and rivet.
Step 5
After gluing and processing the fuselage, glue the keel and stabilizer to it with PVA glue. At the same time, observe the mutual perpendicularity of the empennage elements and the even position of the stabilizer in relation to the fuselage beam. Lacquer the fuselage and cover with bright nitro paint.
Step 6
Adjust the wooden glider model. Tie the pylon at the rear and front ends to the fuselage using a rubber band and move the wing along the beam until you find the desired center of gravity relative to the wing.
Step 7
Perform the first test runs in the gym or outdoors in light wind. Launch the model with a slight throw across the horizon. Using the wooden adjusting wedges between the pylon and the fuselage, achieve the slowest descent speed when planning the model. After mastering the technique of such "piloting", feel free to use the model to demonstrate your design skills - to the delight of the public.
