Why did we start our investigation?Because of curiosity;The interest to the super light aircraft;To evaluate the correspondence of obtained results to the real winged seed flight parameters.
Слайд 2
Why did we start our investigation?
Because of curiosity;
The
interest to the super light aircraft;
of obtained results to the real winged seed flight parameters.
Слайд 3
The Aim of the work
To investigate the aerodynamics
of single blade rotor (SBR);
To construct its (SBR)
mathematical model;To get acquainted with results of scientific researches in this area;
To solve the equation of motion of SBR: to find the angular velocity of autorotation.
To sophisticate the idea of SBR motion.
Слайд 4 We assumed the model of a winged seed
aerodynamics and, based on it, we decided to create
the single blade rotor.
Слайд 7
MEG-1X
MEG-1X was created by American engineer Eugene Gluhareff
in 1955. The creator of MEG-1X, following the ancient
wisdom “the less, the better”, has coherently thrown out all the excessive details, he did not spare even the blades: only one of them stayed with a jet engine, attached to its end.Слайд 8 In USSR the pioneer in creation of single
bladed helicopter was the student of Kharkov Aviation Institute,
Yuri Marinchenko. The original version of helicopter was planned as a backpack weighting 30 kg. He developed this idea during a year and, in 1971 the model was established.
Слайд 9
AliSport
Nowadays the only firm, Alisport, creates the full-size
aircraft with single blade rotor.
They created the famous
one-bladed gliders.
