How to make a glider with your own hands
Smart parents will always come up with their ownchildren useful employment, yes such, that from it then the child will be and for ears to not pull out. The boy is best given in the hands of carpentry tools and wood, offering to create something interesting. And what could be more interesting than creating a flying glider?
Glider yourself: the arsenal
Choosing a tree, the easiest way is to take the pine. Paper is needed for pasting surfaces, it is better to take cigarette paper. The PVA glue is more suitable, the thicker the better. The elastic band ("Hungarian") is needed to connect the removable parts and for the motor. A sharp shoe knife is the main tool. Manual jig saw is absolutely necessary for cutting out curly details. Many of them will need to be pre-processed before manufacturing, so without the participation of serious machine tools can not do.
To begin with, it is necessary to explain to the boy howhandle a knife and a jigsaw. Safety in this case is not particularly useful, to study it it will still be a trial and error method. Also, you should briefly outline the overall work plan and the expected result. Knowing what will happen in the end, he will do his best to make a glider with his own hands exactly as his imagination draws.
The basis of the glider will be a wooden rack width7-10 millimeters and a length of 800-1000 millimeters. The wings are made in the form of a central horizontal section of 600 mm long and 100 mm wide and two curved "ears" with a length of 150 millimeters. The structure of the wing is simple. It consists of two laths five by five millimeters in cross section, passing through the front and rear edges of the wing, and ribs located across the structure every five to seven centimeters. Form they must resemble a drop to provide the glider with a lift. You can make them from two curved racks, but it is better to give the child a stack of thin pieces of wood and a jig saw. Stabilizer and keel are made lattice from the same rods five by five millimeters in cross section. The stabilizer is 200 x 70 millimeters, the keel is a trapezium with bases 70 and 40 millimeters and a height of 100 millimeters. All parts are glued together and clamped with something heavy. After that they are pasted with paper. The main thing is that the paper is stretched. Wings are attached to the fuselage by means of rubber at a distance of about one-third of the length from the front end. The keel is attached to the rear end, followed by a stabilizer. On the nose of the airplane is a drop-shaped weight, the size and weight of which depend on the weight and location of the elements of the aircraft. You can praise the child: he made a glider with his own hands!
After happy hours of work and fun startsyou can think about further employment of the child. If the child is carried away, for example, by decorating an airplane, it is possible to make various models together with him - copies of aircraft. And you can invite him to make a more sophisticated version of the aircraft using a rubber engine. Making airplane models with their own hands is interesting and informative. After all, aviation is a whole world, always attracting boys. If the child was able to make a glider with his own hands, then it can be trusted by everyone. Or almost everything.
