Creative project. Schematic model of an airplane with a rubber engine.

I recently found a reel with a rubber band for fishing (for casting the so-called donkey) and, as usual, figured out how it could be used in aircraft modeling. Two ideas came to mind:

1) Attach the wing 2) Rubber motor

The second idea interested me more than the first. Why not try building a model with a rubber motor? Yes, there was also a competition for articles... Unfortunately, or maybe fortunately, I don’t know any calculation formulas, and I don’t need it yet - in a word, I built it by intuition.

Looking ahead, I will say that the model was not a success =( Either it turned out to be too heavy, or a special rubber band was needed, but the rubber motor did not work. The model looked kind of scanty, unfinished.

However, the plane was planning, and this forced me to still participate at my own peril and shame in the competition.

I wrote the article on making the model even before the first tests, so I didn’t yet know about my failure =)

What will you need? — A sheet of ceiling paper (I lost a sheet somewhere) — A wooden ruler (consumables) — An iron ruler — A sharp knife (the ability to wield it) — The same rubber band (preferably stronger and longer) — Several paper clips — Possibly a drill — Air screw (preferably small in size with large increments) - Thin marker or gel pen - Printer for printing drawings - Possibly a clothespin - Thin aluminum plate (can be done without it or with any material with a smooth surface) - Small pliers (bend paper clips) - A couple of toothpicks - Titan glue or an analogue - Perhaps 5-minute epoxy or other epoxy resin My ceiling was 4 mm thick, so all the drawings, etc. were designed for exactly this thickness of the ceiling. Let's begin.

This is what happened when I first drew the fuselage =)) Funny =) There’s no need to laugh, it will be better later: Hmm... Not very good, but oh well. This is what happened after cutting: By the way, the ceiling has one feature: it bends in one direction better than in the other. This depends on the direction of the fibers of the sheets. The fuselage should be positioned PARALLEL to the grain, i.e. It should bend worse in length than in width. The same applies to the wing and, in general, all ceiling models!!! Kiel turned out to be simply terrible, but oh well. It is important for us to maintain the width of the fuselage throughout its entire length, so that the elastic does not fold it in half. Two stripes in the middle are where the slot for the elastic is. Next, we cut out exactly the same half of the fuselage. There is one important point here. The second part must be cut so that it is a mirror image of the first part. Let me explain. It may be that your ceiling is not perfectly level. Then one half will look like this: We need to make sure that when gluing the second part is bent in the opposite direction - this will strengthen the structure and the fuselage will be even. This is what it should look like: But I glued these halves in reverse (not like in the photo above: I glued the top half to the bottom). Pour a little glue onto one side, spread it with a toothpick, leaving a THIN layer of glue. We wait a couple of minutes and stick the other half. It is unlikely that you will be able to cut and glue everything perfectly, so after the glue has set, we take a sharp knife and trace our fuselage along the edge. IMPORTANT: Keep the knife at right angles to the fuselage surface. This is what is left of my fuse =) Previous — Next >>

The process of making an airplane using a rubber motor with your own hands

First about materials and tools. Everything is as accessible as possible here. So for the fuselage of an airplane, a stick for sushi, wings from a cardboard box, a pencil for component assemblies, one paper clip and one for fastening the corrugated packaging for fastening to an elastic band, a cotton swab as a bearing, an elastic band as a source of energy are suitable. Hot melt adhesive will be used to connect the parts, an ice cream stick for the propeller, as well as threads will be useful for more firmly fixing the joints.

We can start making our plane using a rubber engine. The first step is the most technologically advanced operation, the manufacture of the propeller. In order to shape the curved blades, hold the stick over hot steam using pliers.

Next we bend it and cool it. The result is a propeller for our future aircraft.

Now we cut out the wings and tail from cardboard. You can choose the geometry yourself, the one that you think will most confidently keep the plane in flight.

We glue the wings and tail with glue to the sushi sticks.

It's time to think about implementing a rubber motor. For this we need a pencil. We cut off a couple of elements from the pencil, about 2-3 cm, and spread it lengthwise. We take out the stylus.

In the first one we put a paper clip from the corrugated packaging.

. and in the second a plastic tube from a cotton swab.

We first cut the tube from the central part of the stick. We put the separated halves of the pencil back together and fill the parts installed in them with hot glue. Let's start making the propeller assembly. We take a paper clip, pass it through the plastic tube in the pencil and insert it into the hole in the propeller. Next, slightly bend the edge of the paper clip and fill everything with hot glue.

Now you can install a pencil with a paper clip from a corrugated container onto the frame closer to the tail, and the propeller assembly opposite closer to the bow.

In this case, it is necessary to clearly measure how the rubber band can twist so that it does not tear, ensures optimal twisting and does not tear out the elements of the rubber motor. For reliability, it is better to attach the rubber motor units to the stick using thread. Now all that remains is to install the rubber band, twist the propeller in the desired direction, which is important, and launch the plane.

In this case, the plane will not only glide due to the initial inertia, but also due to the fact that the propeller will pull it.

This is a simple children's craft you can do with your children so that you can not only make an airplane together, but also lay the foundations for the operating principle of propeller-driven airplanes. After all, flying an airplane with and without a rubber motor will clearly show the difference in flight range. Well, in addition to popular science information for the child, we would like to wish, first of all, positive emotions during the assembly and operation of the aircraft.

I present to your attention my simple air glider, with a rubber motor, made with my own hands from scrap materials. The guys and I actively made such gliders in my childhood, so I actually decided to repeat what had been long forgotten. It's very exciting.

What I used:

• thin strip (for old windows)
• plastic bottle
• fishing gum
• glue
• pen refill
• paper clips

Cut out blades from a plastic bottle. Next, glue them to the toothpicks.

From pieces of the lath and empty paste from the handle we form a seat for the screw. We fix it with thread. We make the blade holder from a paper clip.

Also, from a paper clip, we make a hook on the back side of the rail. We attach an elastic band to it and pull it between the screw and the end of the rail. Cut two wheels from a piece of foam padding. We also make a chassis from wire.

We also cut out the tail and wing flaps. We attach it to the glider.

The next stage is the wings. The main thing is to correctly design these moments, otherwise, in case of incorrect weight distribution, it will either fall on the tail or on the propeller. What is not good.

That's all. The glider is ready. Thank you for your attention, watch the video for more details.

Options for older children

For more experienced designers, there are options for making more complex models, but they are also more interesting in terms of aerodynamic capabilities and may have properties such as:

• Possibility of forward gliding (when the airliner is designed in such a way that it does not roll over on its side).
• Flight range (from 100m).
• Duration of stay in the air.

So, consider an airplane that can fly far. This is what this handsome guy will look like:

To build a stable airplane that flies straight and fast and does not fall over on its side, use the following diagram:

Stable

An airplane with large wings, which also has sufficient flight speed and a long stay in the air, deserves special attention.

Big wings

For those who want to create a plane that is not afraid of collisions, a paper aircraft with a blunt nose has been created, which, at the same time, flies excellently.

No collisions

One of the favorite aircraft models among enthusiastic aircraft designers is the powerful and fast “Groza”, which is assembled as follows:

As a result, you get this beautiful plane:

Airplane on a rubber engine

Hello to all fans of making flying model airplanes! We bring to your attention instructions for making a model airplane using a rubber motor .

Materials for making an airplane

In order to make a rubber-powered airplane you will need:

• One bamboo barbecue stick.
• One toothpick.
• Three rubber bands (it is advisable to use a Hungarian rubber band, as it is more elastic).
• Two sheets of A-4 paper.
• Two paper clips.
• Scissors and pliers.
• Threads.
• Ballpoint pen refill.
• PVA glue.

We make an airplane using a rubber engine

1. Make a propeller holder from paper clips

The paper clip that will hold the screw

and a hook for hooking the elastic. Tie them to the fuselage (the base of the plane - a long bamboo stick). To prevent the thread from coming undone, coat it with glue.

Aircraft for the pros

Some airplanes, although they are folded simply from paper without the use of any additional auxiliary means, will require a professional approach to make them. For example, for a super fighter model.

Super fighter

There are also paper airplanes that require scissors, glue, attentiveness and accuracy to make, so it is better to make them with an adult or if you already have enough experience in constructing such structures.

"Flying Wing"

First you need to bend a sheet of paper along the dotted lines (Fig. 1-5), then lift the upper part, forming a rectangle, and cut it in accordance with Fig. 6. In Fig. 8-10 shows how to make a microfuselage (also known as a stiffener); you need to hold the airplane by it during launch. The manufacture of cantilever keels is shown in Fig. 11-13.

The main thing is to make the “engines” correctly; manipulations with them are shown in Fig. 16-18 – they are made by folding and gluing paper into a “tube”. For better flight, you need to make the nose heavier - several triangles are cut out (Fig. 19), which are then glued to the leading edge of the wing (Fig. 20). The manufacture of ailerons is shown in Fig. 21.

Do-it-yourself rubber-powered airplane

The first place that novice pilots—children, that is, those who are thinking about it, but are still not sure for sure, and at that age are not yet capable of it—start their flights, with toy airplanes. The simplest option would be a paper plane, you can simply fold it and launch it, it will float in the air like a glider. We discussed this option in the article “How to fold a paper airplane.” More advanced versions are capable of slightly assisting themselves in flight. So, for example, an airplane is on a rubber tire, where the potential energy of a twisted rubber band is capable of turning the propeller, which pulls the airplane forward. This option is already known to many adults who, as children, assembled such an airplane with their parents. Now it’s your time to pass on the experience to the children, showing them how it is done and on what principle the aircraft operates on a rubber tire. And in order to make it easier for you to navigate and not really rack your brains over what to use for production, we suggest that you read our article - a cheat sheet.

Options for Beginners

There are several ways to make a paper airplane that are accessible even to children. At the same time, it will float perfectly in the air and will be able to cover a distance of up to 100 meters.

The main rule when creating even the simplest classic paper airplane is the symmetry of both sides, which will later become wings.
