I want, again, to please you with a story about the author of many aircraft models known to all of you, such as the Mirage and Space, which I have already talked about and will continue to tell.
This time, the author decided to surprise us all. model aircraft on impellers. After long viewing photos of prototypes, the author settled on the beautiful Concorde liner. Captured this author's aircraft with its sophisticated forms.
After the author found the drawings suitable for the work, he made all the calculations of the main parameters of the model.
Length - 1850 mm.
Span - 840 mm.
Impellers - 64 mm 2 pcs.
The total thrust of impellers is 900 g.
Battery - 3S2200
Regulators - 20A. - 2 pcs.
Servos are different.
Flight weight - 1250g.
The ceiling is 3.5 mm.
Heater "Penopleks".
PVA glue.
Epoxy resin - epoxy.
Scotch is different.
Knitting needles made of metal.
Wooden slats.
Here according to this drawing this model was made.
The wing is glued from two layers of the ceiling.
Here is the wing center.
Glued wooden slats to strengthen the wing.
Under the fuselage skin are glued frames cut out of insulation.
Saving the weight of the model, instead of frames, small pieces of insulation are glued onto which the external fuselage skin is mounted.
The outer skin of the tail section of the model is mounted.
The nose of the fuselage is made removable. The bow is mounted on dowels made of “skewers”.
Lightweight design of the bow of the fuselage, made of skewers and insulation, sheathed by the ceiling.
Nests are glued in the nasal septum, for the nasal frames of the nose of the fuselage.
Also, a servo machine controlling the front landing gear is mounted on it.
The battery is located in front of the fuselage.
A hatch was made to replace the battery.
Tubes for impellers made of three layers of Whatman paper.
For durability, when installing impellers, ceiling strips are glued.
Cutouts are made in the wing exactly to the size of the impellers and the shape of the “lip”.
Impellers are mounted on epoxy.
Checked the impellers for vibration, balanced.
Regulators are installed in the place of the best airflow for cooling.
Glued rectangles 40 x x 40 mm in size from 3 mm plywood. Chassis racks with M4 screws will be mounted on them.
All wires are laid.
Front landing gear
To save weight, for the chassis I used F 2mm spokes,
A removable keel mounted on pins is made. When flying, the keel is fixed with transparent tape.
When designing the appearance of the model, a marker was used. The porthole drawing is glued with transparent tape.
The first tests of the model showed its abilities. The model is easy to operate, stable in flight.
The author notes that the model is suitable for slow flights, but it is desirable to increase the traction of the impellers.
The first flight of the Concord aircraft model in front of the audience.
Thanks to the author for a great model. I will build myself such a great pleasure.
