ELASTO 3,1 / 3,8 m

ELASTO – Back to the roots…

During the last 5 years we are busy at work on the evolvement of new Elasto model. Our objective is to produce an airplane with the ideal wing, inspired by the wings of birds – the dream of aerodynamicists and the airplanes constructers of the early era, that have not been successfully developed until these days. The wing, that allows air to flow around without any interferences or induced drag caused by control surfaces, rigid on it´s leading edge and flexible on the trailing one, allowing to reach the highest possible wing´s aerodynamical clearness.

An elastic wing is truly a dream that could allow to change it´s characteristics from simple bending of the trailing edge to the whole form of the airfoil resulting in the highest possible glide performance and the controlability of the glider. Versatility of this system allow the glider to be used in various competition categories, mostly the F3F, F3B and F3J complemented with possibility of changing the wingtips of the 3,1m and 3,8m of wingspan.

After solving all important constructive questions and problems, the first tests of our idea were in practice! At this stage of Elasto development, we tested the basic concept in the wind tunnel and also for the first time in flight.
A testing prototype was build from the Espadita fuselage and elevator, and the brand new wing construction, adapted from the outer wing of the Ellipse 2. We can tell the test  was very succesfull , flying performance and  attributes overcomed our expectations.We are  happy after all the engineering hours ……..

 

At a later stage of testing, we have produced a wing middle part of our future Elasto.
On wing middle part we tested, among others, the newly developed drive mechanism of the flaps.
When we have seen the  simple-looking mechanic, we almost did not believe how many experiments were necessary! The genius is in the simplicity ….

 

At the same middle part we also tested the drive mechanics of the ailerons with 2 servos. This allows a wing trailling edge twisting. The harmful resistance between the wing and the thrust aileron is  eliminated this way.

Despite that there is still a lot of work awaiting us, we can proudly announce that the plane will be finished and available for the 2017 season.
